Pruvit Keto//OS Exogenous Ketones Review

Available Now: Keto Reboot 60 hour fast – AMAZING!

Check out my Pruvit Sales, Specials and Samples page here. 

Hello! Hi, my name is Rachel Vrabel and you can find me on Instagram @womensblogtalk or on Facebook.

Today I’m reviewing a supplement made by Prüvit called Keto//OS (Ketone Operating System), which is a ketones powder you mix with water (either charged or decaf) and drink once or twice daily that tastes delicious!

One serving of Keto OS puts your body into the metabolic state of ketosis in under an hour by flooding your body with exogenous ketones.

keto weight loss journey

Me before and after Keto-OS

The skinny is – you can help your body burn fat rather than glucose (carbs/sugar). It helps you to eat less, and is a great tool for intermittent fasting.

What I love most about drinking ketones however, is how they make me FEEL – happy and with sustained energy throughout the day, and much better workouts!

The Ketogenic Diet will also put your body into ketosis, however it’s very strict – less than 20 grams of carbs per day. To put that in perspective – one cup of rice has about 48 grams of carbs. Yea….

But what if you don’t want to follow a super strict diet but you still want the benefits of being in ketosis?

Or what if you want to make your transition to a low-carb or ketogenic diet a HECK of a lot easier? (with no “Keto-flu” symptoms such as headache and low energy).

This is where Keto//OS sets itself apart from every other supplement on the market!

Keto Weight Loss Results – Round 1

Ok so I’ve had two rounds of experience drinking Keto OS and I want to tell you about both times, because the difference is what’s important!keto os before and after photo

The first time I started drinking Keto OS (Orange) was in Jan. 2016 and I lost a total of 11 lbs in a month!

This was huge for me since the prior year I’d gained 15 lbs going through fertility treatments. I went through 3 IVF cycles, lost a pregnancy, and went through a D&C surgery.

The hormones were no joke. No matter WHAT I did, the scale did not budge. For months!!  However, after starting the Keto I lost weight easily and was never hungry. 

So why did I stop and gain the weight back? That’s easy…I got complacent. I got out of the habit of drinking Keto, and I started eating bad again!

Keto Weight Loss – Round 2

Daily Ketones for Over a Year (Jan. 2017 – to the present!)

Round #2 with Keto OS was my game changer – I’m down 17 lbs and I’ve kept it off for over a YEAR. Keto os review and results keto os review and results

Replace bad habits with something healthy and stick with it and guess what? It’s much easier to stay on track!

My cravings basically disappeared and eating fewer calories feels easy.

I took these photos Jan. 1, 2017 and April 28, 2017 (in these pics I was down 15 lbs, but I’ve lost a couple more lbs since then).

Here’s how my Keto-OS weight loss transformation went down:

  • My first ten days on Maui I lost 6 lbs
  • By week four I’d lost 9-10 lbs
  • By the end of month two I’d lost 15 lbs
  • Total lbs lost: 17
  • Total Body fat lost: Went from 25% to 18% in four months

I lost the most weight around my middle, my back, butt and top of my thighs, and my face is slimmer and less puffy.

Why I Committed to Drinking Ketones

In January (as many of us do in January) I got tired of not fitting into any of my clothes, I’d gained back those 11 lbs and then some.

I felt bloated and miserable, very low energy and I’d stopped going to the gym.

So I ordered the Max Maui Punch which was their new flavor at the time and absolutely LOVED it and started drinking it every day. keto os before and after keto os max

I also joined Orange Theory Fitness in Jan. which is HIIT training (run, row, weights) and I do that about 2-3x per week and usually play some beach volleyball on the weekends.

So yes, I’m very active. I’ve learned over the years that I can lose weight, sure, but add in exercise and you will shape your body as well.

I highly encourage exercising and eating a low carb diet, it makes the ketones work that much better!

In fact, if you’re interested in this product just for quick weight loss results, it’s a great tool to use, if used correctly.

I did eat a strict ketogenic diet my first month – and this DID help to really get my body into a deeper ketosis to burn even more fat, but now I do eat some carbs.

Now I do a lot of intermittent fasting, mainly eat low carb/high fat during the day, and eat good “most of the time.” However, I have plenty of cheats and don’t gain weight back – so to me that is priceless!

Since being back on Keto, I have my energy back, my mood is lifted, my skin is clear, and I’m a LOT more focused and productive in life.

Why Am I Writing About Pruvit Keto OS?

I originally set out to review Keto OS is because before I tried it,  my sister also lost 12 lbs in 3 weeks and looks amazing!

It’s also helped her energy level, mental clarity and focus, and it’s safe for her to drink with her medical condition.

My sister has epilepsy and her Dr.’s have always recommended a Ketogenic diet (which is anti-inflammatory diet), but she has a hard time with diet restrictions, who doesn’t?

Drinking Keto OS has been a safe and effective way for her to lose weight – weight that’s been impossible to lose since she’s on medications that cause weight gain!

It really helped her get a handle on her appetite and make smarter choices, and she also practices yoga. She had these results drinking the Orange Dream flavor, which contains MCT in it and is GREAT for weight loss.

So what is Keto OS and how does this first-of-its-kind supplement put your body into ketosis?

What results can you expect with Keto OS? And does Keto OS have side effects? Let’s find out!

What is Prüvit Keto OS and How Does It Work?

Prüvit’s KETO//OS “Bio-hacks” your body into ketosis in under an hour. pruvit results

In fact, you can pee on a ketone test strip 45-60 minutes after you drink it to “pruvit.” These are available at drug stores, and you can read about testing for ketones here.

Here is a picture of my keto strip, one hour after drinking a full serving of Raspberry Lemonade. Boom! Some people eat a strict ketogenic diet for weeks and don’t see this level of elevated ketones.

Keto OS contains a patented formula of the highest quality ketone mineral salts (BHB -Betahydroxybutyrate) in a blend of amino acids and minerals.

The Orange flavor also contains MCT which equals high energy fuel for the brain and increased fat burning.

Ketones produce 38% more energy than glucose (carbs/sugar) and preserves muscle! It is a fuel source.

The brain absolutely loves ketones (the brain can only use either glucose or ketones for fuel), that’s why this product provides so many other health benefits aside from weight loss, such as mental focus, energy, and protection from Alzheimer’s.

Normally, ketones are only produced in the body during periods of fasting, but when’s the last time you fasted, or even at less than 20 grams of carbs in a day? Gave up pizza or bread? 😉

What is Ketosis?

pruvit long term benefits

One year to the day of daily ketones!!! Jan 2018

Click here to watch a short video explaining ketones, ketosis and how Keto OS works

Ketosis is our native state – when we were hunter-gatherers, we would go into ketosis and burn fat (instead of muscle) until we found our next meal. Our bodies thrive going in and out of ketosis!

Babies are born in ketosis, and nursing babies are in and out of ketosis.

Mom’s give their babies ketones through breast milk during the time when their brain is developing the most.

So…why deprive yourself now of this natural metabolic state we thrive in?

Some of you may NEED Ketones in your Life

How’s your health? And your waistline? Are you addicted to sugar and carbs?

Metabolic syndrome is projected to surpass cigarette smoking as the leading factor for heart disease. Obesity (from overeating carbs and sugar) and lack of activity are to blame.

There’s no doubt we are a carb-loving and sugar addicted society, and that’s why our waistlines have gotten out of control.

We will never go into a state of ketosis naturally unless we follow an extremely strict ketogenic diet and even then it can take weeks to get there.

The long of the short is, drinking exogenous ketones twice per day allows your body to safely go into ketosis and experience the abundance of health benefits of ketosis.

Ketones are a fabulous tool to regain both your physical and mental health.

Do You Have to Eat a Special Diet to Lose Weight on Keto OS?Ketogenic diet

Many people ask me how to take Keto OS, and this is my recommendation:

  • Drink 1-2 servings of Keto OS per day and a new diet will follow naturally – because you won’t be as hungry and your carb and sugar cravings will be squashed!
  • If you have a significant amount of weight to lose, DRINK TWO SERVINGS PER DAY (optimal dose for everyone). And make sure the Orange Dream with MCT is in your rotation of flavors.
  • It becomes much easier to eat smaller, healthier meals, and even intermittent fast – it’s a BREEZE!
  • Keep in mind, if you drink ketones and continue to eat a high carb diet, guess what? You’re not going to lose a ton of weight.

The folks at Pruvit do recommend a ketogenic diet for optimal results (low carb/high fat), but you don’t have to follow it at the strictest level to experience benefits from drinking Keto OS. 

Will you burn more fat if you eat a low carb, ketogenic diet?  YES, of course! And you won’t feel hungry.

At the very least, try to eat low carb and get used to eating high fat snacks – FAT BURNS FAT – continuing to eat a high carb diet is not going to help you stay in ketosis.

If you’re following a ketogenic diet already and have trouble getting into or staying in ketosis – drinking ketones will help you get into a deeper ketosis and stay there longer.

Also, drinking ketones is a fabulous tool to help you easily transition to a ketogenic diet without feeling those “keto-flu” symptoms such as headache and fatigue.

Keto OS – How Many Should you Drink? And When?

The recommendation is to start by drinking one full serving in the morning and a second serving between 1 and 4.

If you’re starting with the Orange flavor (this is the only flavor that contains MCT), it’s best to start with a half serving for your first couple of days so your tummy can adjust.

Take it slow, and take it back down to a half or even quarter serving until the tummy issues subsides. You are “Keto-adapting.”

But there’s no hard or fast rule on when to drink your ketones, drink them when you feel you need the energy!

I love drinking mine about an hour before a workout (and that’s optimal if you’re using it as a pre workout to increase fat loss).

However if fat loss and weight loss is your primary goal, drinking two per day is really the optimal level and Orange is a great choice since it contains MCT.

What Does Keto OS Taste Like?

keto os orange dream 2.1

Keto OS Orange Dream 2.1

The new Orange Dream 2.1 came out in April 2016 which is an optimized version of the original Orange flavor. Here’s a picture of the Orange Dream Ingredients.

The Orange Dream flavor tastes just like a creamscicle (or Orange Julius if you remember those), and if you add a squeeze of lemon it tastes like lemonade! It’s yummy!

Pruvit brought their exogenous ketones to the market place using Dr. Dominic D’Agostino’s patented formula of ketones + MCT (medium chain triglycerides i.e. fat extracted from coconut).

The Orange Dream is “special” as it’s the only ketones flavor that contains MCT. The MCT allows the ketones to have a more “slow release” and can give an edge to appetite suppression and fat burning. Great for weight loss!


The Orange contains a bit of milk powder (not much) to bind the MCT to the ketone body (it’s gluten free, but not dairy free or vegan).

Keto OS Chocolate Swirl 3.0

Keto Chocolate Swirl Kan servings


The second flavor Pruvit launched is the Chocolate Swirl 3.0, which tastes like a tootsie roll!  Here’s a picture of the Chocolate Swirl ingredients.

What’s Different about Chocolate Swirl 3.0?

  • Includes a Prebiotic – a food source for the good bacteria in the gut making them stronger and more able to fight off the bad bacteria and also helps with gastro intestinal upset
  • Vegan, Dairy and Gluten Free
  • Contains a short fatty chain amino acid blend – great for inflammation (all ketones are anti-inflammatory, but this one may give an edge on inflammation i.e. for fibromyalgia and other related inflammatory conditions).

Keto OS Max Maui Punch

why is keto os bio max better

The Keto Max Maui Punch has been hands down my favorite flavor for a while now – it tastes just like Hawaiian Punch!

The Max flavors (Max salts are a bit different from the OS) have the most pure, most bio-available form of ketones, meaning your body can more easily absorb it so there’s a faster uptake, quicker peak, and provides more energy – the Max is roughly 40% stronger.

Keto Max Maui is gluten-free, dairy-free, Vegan and Kosher Certified (like the Chocolate) and is the most advanced ketone delivery drink they offer, thus “the MAX.”

This stuff is absolutely amazing. I’m energized all day, and I have so much motivation to work out and it keeps me feeling so sharp, and happy! It’s the BEST preworkout supplement I’ve used!

Keto OS Max Raspberry Lemonadepruvit reviews

Keto Max Raspberry Lemonade is now part of the permanent menu in both Charged AND Decaf.

Keto Max Raspberry Lemonade tastes ah-mazing, like off-the-chain good!

It is so refreshing just as you would imagine this flavor would be and reminds me of Country Time Lemonade!

It has the same quick uptake as the other Max formulas and it’s been my go-to flavor since it first came out over the summer.

I go back and forth a lot with the Maui and Raspberry – it’s nice to have options!

Keto OS Max Swiss Cacaoketo os new flavor max swiss cacao

The new Max Swiss Cacao is made with real cocoa. Chocolate lovers – THIS is your flavor!

Keto Max Swiss Cacao is similar in base formula to the Keto Max Maui Punch except it’s Swiss chocolate flavor – like delicious, iced cocoa tasting flavor!

My sister described the flavor as being somewhere in between dark chocolate and milk chocolate. It’s a great decaf choice for afternoon or evenings – if it’s ever too late in the day for a charged, I always go for the Swiss decaf!

If you have tried the Chocolate Swirl and it’s not chocolatey enough for you, you will love the Swiss Cacao!

Keto OS Drink Recipes

What does keto os taste likeKeto tastes really good mixed with a sparkling water, like La Croix! Pruvit offers some fun recipes you can whip up with your Keto powder.  One of my faves is the Maui MaxTai:

  • 1 pack Keto OS Max Maui Punch
  • 16 oz pineapple-strawberry flavored sparkling water
  • 1/2 oz fresh lime juice

Shake, pour over ice, sip, and pretend your on an island on vacation – it’s so refreshing!

Keto OS New Amped Blue Ocean – If you like Pina coladas…..Amped Blue Ocean

Speaking of new flavors – What’s all the Hype about Pruvit’s new flavor Keto OS Amped Blue Ocean? 

With double the caffeine and stronger feel all around, this is the stuff I drink for those days I have a lot of work, or a tough workout. Amped is magical!

I prefer the regular Max for daily use, but LOVE having this as an option. I can’t wait for the full release.

Blue Ocean also contains AC-11 for DNA repair (reverse aging), which is also in the new Keto Kreme!

Check out my blog post on why AC-11 should be part of your anti-aging routine.

Keto Splash – Watermelon Grapefruit Fusion!keto splash reviews

Pruvit has done it again, in a watermelon grapefruit Max formula!

This new flavor contains AC-11 DNA repair and added B3, B6 and B12 Vitamins, and you can check out my Keto Splash blog post here.

I love the Splash, I am low on Vitamin B so it gives me an added boost of energy and it’s very light and refreshing.

They’ve had a few flash sales on the Splash, but it’s not on the menu yet!

New Keto//OS Amped Midnight #MYSTERYMAX FlavorAmped Midnight keto

Pruvit released their “Mystery Max” Amped Midnight in early December and it’s AMAZING, and so smooth.

This is a new black cherry vanilla flavor and is “AMPED” like the Blue Ocean, contains AC-11, is purple (almost black) and is delicious!

Amps me up exactly the same as the Blue Ocean – it’s fantastic!

Keto Kreme with Functional Fat Technology (FFT™)

Pruvit’s Bulletproof Coffee – New Optimized Formula with Collagen!

New keto kreme from pruvitPruvit’s Keto Kreme is a fat supplement powder you mix with your coffee or tea that’s great for boosting fat loss, an energy and brain boost, and is very filling and yummy!

Here’s a picture of the New Keto Kreme ingredients.

Keto Kreme should be considered complimentary to Keto OS since it doesn’t contain exogenous ketones – but they encourage ketosis and help your liver ramp up its own ketone production.

It’s great to use for fasting in the morning to keep you full until you drink your ketones and should increase your fat loss and give you plenty of brain energy.

How to use:  FAST on the Keto Kreme until you get hungry, then drink your ketones, then when you get hungry (lunch time or later) eat a low carb/high fat meal. Super burn!

Or: Drink half hour before dinner (with a decaf tea) and your appetite will be a lot less. Remember, FAT BURNS FAT, and fat calories are dense – they are very filling.

Keto Kreme contains a healthy serving of fat (12 grams) made from coconut oil, MCT Powder (Medium Chain Triglycerides) and sweetened with stevia.

FAT LOSS TIP: I encourage anyone who’s main focus is fat loss or weight loss to intermittent fast (google the health benefits). Drink a Keto Kreme and then wait until you start feeling hungry, then drink a Keto//OS or Keto Max. Eat low carb/ketogenic and drink a second serving between 1-4.  The key for using this product for fat loss is to stay in ketosis as long as possible.

What’s New about the Keto Kreme?

  • Four different patented collagen formulas, new “Functional Fat Technology” *FFT
  • Collagen, which benefits: hair, skin, nails
  • Smoother than the old formula, more creamy, can even mix with just water and ice as a shake
  • AC-11 for DNA Repair – ANTI-AGING
  • Tastes similar to the old formula but you can even mix it just with water for a creamy tasting shake!
  • Neuroprotective benefits from MCT, fat burn, keeps you full, gives you energy.

Keto Kreme Pancakes

My sister and I made some Keto Kreme pancakes the other day and they are amazing! Super simple ketogenic breakfast, brunch, or snack.

One pack Keto Kreme, two eggs, two tablespoons of cream cheese, and fry them up in coconut oil.

Does Keto OS Have Any Side Effects?

Like any supplement, not everyone will have the same exact experience. If you’re sensitive to caffeine and drink the Charged version late in the day, then you may have trouble falling asleep, just like coffee may keep you up.

Some people report an upset stomach when they are adjusting to the Orange flavor (since it contains the MCT oils), and this is the reason to start with half a pack for at least a few days, or longer if necessary.

One more thing, you may notice you pee more frequently your first week or two. This is normal as being in a state of ketosis naturally flushes the body of water and along with it goes the fat and electrolytes.

For this reason, be sure and drink plenty of fresh water throughout the day! (half of your body weight in ounces if you can). The side effect of this may be a FLATTER TUMMY;)

I also recommend adding a basic minerals supplement when drinking Keto daily and using Himalayan salt on foods.

Some people when starting ketones even gain a little weight their first week or two (not common but it does happen)!

When the fat cells start to lose fat, they fill up with water temporarily, and then when the fat cell finally collapses, you should experience something called “The Whoosh Effect” and you’ll see a drop on the scale.

More on How I Feel Drinking Daily Ketones

What I’ve felt since I started drinking Keto Max is increased energy and my ability to focus on tasks without becoming distracted is remarkable.

keto os reviews

Keto OS gives me a ton of energy for Volleyball, tournaments take a lot out of you!

I’ve been sailing through each day no longer experiencing those slumps of energy like I used to, or staring into space when I got bored or didn’t feel like working. No more brain fog, and no more afternoon coffee.

The Keto keeps me fueled and energized all day, but definitely NOT in a jittery-energy sort of way. Just an awake, let’s conquer the day feeling!

It’s a very level feeling of energy, unlike coffee where you might feel pepped up for a little while but then crash.

I’ve also been powering through my workouts at the gym and pushing myself through those somewhat painful moments but gaining strength because of it, whereas before I might just stop when it got too tough.

It gives me energy to get my butt to the gym when I would sometimes blow it off….you know how that goes. Half the battle is getting there!

Even my volleyball game has improved. Having the endurance to play game after game has been easier, more fun, and made me more competitive! I never go to play ball without drinking a full Charged on the way!

As you can tell by my lifestyle, Keto works so well for me because I’m active as well as eat a lower carb diet. It’s not a quick fix weight loss miracle..just to be honest.


If you’re reading this and you consider yourself more hardcore, i.e. you’re a weight lifter, crossfitter, triathlete, iron man or woman, someone who wants to get completely shredded, willing to eat a ketogenic diet and do some intermittent fasting for optimal results, read about Pruvit Keto-OS’s plan for getting into the N8TIVE ZONE.

Other Health Benefits of Keto-OS

keto os results

My Mom’s 6 week Keto results

Aside from the obvious fat loss benefits, Keto OS and Keto Max have many other health benefits and the research section of their website has a ton of published PubMed research and clinical trials to back up their claims.

For me personally, inflammation is an issue. I have blepharitis of the eyes (ocular rosacea) and my eyes have definitely improved from the anti-inflammatory benefits from drinking Keto-OS.

Rosacea is inflammation, so if you treat the root of the problem, you’re going to see an improvement. For the first time in a while, my eyes actually look white instead of red! And my skin looks amazing!

Here are some highlights of what Keto OS can help with aside from weight loss:

  • Keto OS fights chronic inflammation, which for some can mean chronic pain or achy joints
  • Provides cognitive improvement and neuroprotection for the brain, which can ward off Alzheimer’s disease.
  • Improves insulin sensitivity for the treatment of diabetes.
  • Improves cellular health and longevity, along with anti-aging benefits.
  • Weight loss – fat loss without muscle loss.
  • Cancer inhibiting – cancer cells can’t live using ketones as fuel (I’m definitely not saying exogenous ketones cure cancer, but there is research that cancer cells don’t thrive in ketosis).
  • Check out my  My Family’s Results Drinking Pruvit’s Keto OSBoth my Mom and my brother have used ketones as a tool to regain their health. They’ve both lost fat and kicked alcohol to the curb which has helped to reduce their high blood pressure to normal levels.

Thanks Rachel for the ketone trial. I really enjoyed all the flavors but found that I liked using the Keto Kreme in my coffee and maui punch best! My results have been great! I actually lost 7 lbs in those 10 days and I’ve gone on to lose 8 more the following month. They keep me energized and not as hungry!

Decided to try the product because it sounded right for me. Purchased $155 jar of Pruvit Keto OS and started. The first few days I had a terrible headache from it but than it stopped. That first week I definitely felt more energetic and good. Also that first week I lost 4 lbs. I felt great. I started the Keto diet and even signed up with a helpful website. I have 10-15 lbs max to lose but the reason I was sold on this product is that I was told it would help with my Crohn's disease…….. I do not exercise, and I do enjoy a cocktail (sugar free cran & vodka)… With that being said , my second week taking this product I noticed the energy level decrease AND the scale was telling me that I've put on 5 lbs. After the full second week of taking this product I started to feel black aged and my stomach started to act up. The third week was the same with decrease of energy and bloating/stomach flare ups. The fourth week was the same. As of today, a full month of taking this product I have not only gained 5lbs extra but my Crohn's has flared up. Considering the fact that not only did I take it for a full month plus followed a strict Keto diet, I am very disappointed. Do not waste your money, this product does not work for everyone. And if you decide to try this product, consult your physician first .

one thing ppl don’t understand is Keto is a fuel source. exogenous ketones give you energy much like carbs except with more energy, and you don’t have the crashes. great for endurance athletes and for intermittent fasting. it’s been a game changer for me for competing in sports.

For any guys reading this blog, I found the Maui to be great fuel as a preworkout supp for weight lifting and it’s made my workouts stronger, and I’ve lost a good bit of body fat. I don’t eat a pure ketogenic diet and it still works. I try to eat healthy but I do eat my share of carbs. Only gave it 4 stars because it’s a bit pricey but it’s worth it.

Keto OS is amazing!

I was first introduced to Keto OS by a friend at volleyball. She told me that she started to drink it every day and has already started to drop weight. I saw the results that she was getting from it so I decided to try the samples that she gave me. I liked the way it tasted and the energy it gave me but was hesitant to purchase it because of the price but I decided to purchase it and give it a try. I am so happy that I made the purchase and now it is an essential part of my day. I purchased the KAN in the orange dream flavor. I drink it first thing in the morning, without it my day is not the same. Keto OS provides me with the energy that I need to get through my hectic days without the jittery feelings that other products give. I feel more focused, alert and happier when I take it. The energy that Keto OS provides is the perfect amount that I need to get through the day without crashing and I can fall asleep at night without any problems. Keto OS helps suppress my appetite as well. I don’t feel as hungry and when I am hungry I am eating less. The weight loss that I have experienced on this is also phenomenal. I have not been trying to lose weight and I have not gone to the gym in months because my daily schedule is so hectic, I only play beach volleyball a few times a week but have managed to drop about 15 pounds. Everyone gives me compliments on how good I look and I don’t even realize the weight I have lost until I try on clothes that used to be tight on me are now too big! Keto OS is an amazing product and I am so glad that I have tried it and I will continue to purchase it!

Great product!

I’ve been drinking this stuff for a year now! My favorite flavor now is the Maui! Like Kool-Aid or something! I had a similar experience to you! I make sure and eat healthy while drinking it, and make time to workout. With all the energy that it gives you, put it towards something useful, right?!

4.7 5.0 23 23 Thanks Rachel for the ketone trial. I really enjoyed all the flavors but found that I liked using the Keto Kreme in my coffee and maui punch best! My results have been great! I act Pruvit KETO OS Review & Results – UPDATED DAILY!

Q: How much weight should I expect to lose daily? -Terry

A: Hi Terry, everyone is different, but if you have more than 20 lbs to lose, some have reported up to a pound a day when they get started. For someone who is already closer to their goal weight, maybe closer to 1/2 lb. It also depends on your diet and whether you exercise. While you don\'t have to change your diet to lose weight using Keto, you\'ll always get faster results if you try to eat a moderate protein/high fat/low carb diet.

Q: When I drink on an empty stomach in the morning I don't get hungry until sometimes 1:00. Is this bad to not eat for that long? It suppresses my appetite so much I almost have to remind myself/force myself to eat. I did read something about intermittent fasting but I wasn't sure if that was the best way. Should I eat even if I'm not hungry? I've lost 10 lbs in two weeks! And easily! Thanks. -Tiffany

A: Tiffany, sometimes I do that, drink in the morning and then don\'t eat until I\'m hungry. It is called intermittent fasting and it\'s ok to do. Just make sure you eat by lunch time if you\'re going to skip breakfast. Rachel

Q: I'm a 50 year old female. I had a large brain tumor removed August 4th. As a result I've lost a lot of cognitive ability, memory issues, and focus problems. I also gained 40 pounds from no activity. Steroids and stress eating. I heard Keto/os might help. I purchased and notice I am in ketosis an hour after taking it but get not a trace within 2-3 hours. Does this mean it's not working for me? is it safe to take several times a day? -Michelle

A: Hi Michelle, first of all, I\'m so sorry you\'ve had to endure so much! Are you peeing on the keto sticks? I never bothered.... I knew it worked for me because it suppressed my appetite, I lost weight, and I have great mental focus and energy. You can drink up to two per day (no more). This will definitely help keep you in ketosis longer and I\'ve read that drinking 2x per day should keep you in ketosis for 24 hours, so maybe try again but don\'t get focused on the strip. One a day worked for me but everyone is different, and with more weight to lose, I would recommend two. I would do the decaf in the afternoon - the charged version may keep you up at night and you need your rest :) Good luck to you and I\'d love to hear back from you to see how things progress.

Q: Hi there. What kind of workouts did you do to lose 10 pounds in 4 weeks on keto? -Heather

A: Hi Heather, thanks for your email. I usually went to the gym 1-2x per week and I mostly did plyo body weight stuff in the back room along with some kettlebell swings (15 lbs),  and I like the ball slam (only use 10 lbs).  Some free weights also, but nothing with super heavy weights.  I also play beach volleyball 1-2x per week so that gives me my cardio. So I\'d say on average, I was active at least 3 days per week with a pretty vigorous workout. But like I mentioned in my article, I had been doing all this and more and the scale was not budging! When I started drinking the keto, I got fired up with energy and it helped me to push myself a little harder in the gym and the weight finally started coming off. I\'m not a gym rat by any means, but I do stay pretty active.   I will email you one of my plyo workouts, in case you\'re not familiar. I have a ton of these if you\'re interested in more. I find that if I go to the gym with a plan in hand, I do everything. I hate just wandering around the gym and never get as good of a workout in.    Thanks! Rachel

Q: Ca I add a scoop of protein to my drink. -Jackie

A: Jackie, you can, but it\'s more effective if you drink it separately. I actually asked this question\'s not a huge difference but every bit helps! So if drinking it separately was 100%, maybe mixing it with a shake it would lose some strength so make it 80 or 90%. Personally I would drink 30 minutes before or after. Good luck! ~Rachel

    Love the Maui punch, my workouts have really improved and are much stronger. Can’t wait for the Splash to be offered as a regular flavor, thank you for the samples it was delicious! Let me know when it’s for sale on the website. I want that AC-11 benefit. Thanks.

      Hi Par, I do know a customer who mixes the Maui punch with the Keto Kreme and loves it! You’re getting both the ketones (BHB) and the benefit of the MCT, coconut oil, and four different types of collage from the Kreme when you take both. Even if you don’t mix them, it’s good to drink both. ~Rachel

    I am starting a low carb life style change and need this push but it seems like a lot of money to throw out there on something I haven’t tried. Is there a starter package or samples? I have right at 100 lbs to lose and need a good kick to get it going.

      Hi Jody, thanks for your message. I do offer a 5 day experience to try all the flavors, this is a great way to determine which flavor you like best and would enjoy committing to. I offer these for $35 and that includes mailing. So it would be one of each: Max Maui Punch, Max Raspberry Lemonade, Max Swiss Cacao, OS Chocolate Swirl and OS Orange Dream. I can do all charged or a mix of charged and decaf. Please send me an email to [email protected] if you’d like to go ahead. Thanks! Rachel

    Hi Rachel! Thanks for all the great information. I too along with my wife are doing Orange Theory. Just a week into the workouts. Quick question, I am very interested in the Keto OS product for fat burning. With this product in the body when you work out are you burning fat or just the OS supplement that’s been put into the body? Reading reviews it looks like there has been great success with this product. I am thinking in my case there is still sugar stored in the fat/muscle that would get burned before the fat does. Not sure how that works? I may have the terminology wrong. Once again thanks for the wealth of information and congrats on the success you’ve had in journey through health.

      Hi Mike, thanks for your message! That’s awesome you’ve started OTF, I absolutely love it, it’s the best workout and the most fun I’ve ever done…I’ve done boot camps before and they’re just too intense, I really don’t like flipping tires OR doing 100 burpees, LOL. Keto OS will throw you into ketosis which is when you’re body uses fat for fuel, so you’ll be burning fat. However if you have carbs/glucose in your system (which most of us do unless you’re following a ketogenic diet), then on Keto you’re body is able to duel fuel and use both. So you’re right, in the presence of both glucose and fat, the Keto will use both. Exactly which one first and how much is getting too scientific for me to explain. Dr. Andra Campitelli does discuss this, take a look at these Keto U videos, they’re all short like one minute. I know she talks about dual fueling in one of these, and you’ll probably have a few other questions answered by listening to these. I usually drink my Keto about 30 minutes to an hour before going to OTF, great energy! I definitely push through the hard stuff and keep running so much easier using ketones as fuel. Ketones are a superior fuel source, with more energy/oxygen than carbs. Let me know if you’re interested in a five day experience before purchasing. Email me at [email protected]. Thanks!! Rachel

    Hi there – some people in another company (health and fitness but NOT ketones) claim that its unsafe to push your body into ketosis with this product. Is there any truth to that or research to back that?

    • Rachel Vrabel
      Rachel Vrabel September 2, 2017 at 2:51 pm - Leave A Comment

      Katy, they’re just trying to sell their product… ketones are very safe. Ketones are a fuel source just like carbs and protein, your body uses them as fuel. Babies are born into ketosis and stay there if they are nursing. Ketones are also safe to drink if you’re pregnant or nursing. Being in ketosis is our native state, we were meant to be in and out of ketosis and our bodies make ketones naturally. Check out some of the articles in the research section of the Pruvit site. There’s a ton of third party research. If you see someone or a company bashing ketones, you can bet they are just trying to bait and switch you to their product. Ketones are amazing! I’m going on 9 months of drinking them daily and never felt better. 🙂 Rachel

    What is KAN 30 and OTC 30?
    I had three knee surgeries, last one two years ago but I am still in extreme pain and have a lot of weight to lose. I read your blog and it said to use the Orange dream, which is great advice because I had no idea where to start on this Pruvit.

    • Rachel Vrabel
      Rachel Vrabel August 3, 2017 at 6:57 pm - Leave A Comment

      Hi BJ, thanks for your question. The Kan is literally a can of powder that comes with a scoop, and it’s more economically priced vs. the OTG (On the Go) envelopes, those are individual servings. It’s the same formula whether you get in a Kan or envelopes, but only the Orange Dream and the Chocolate Swirl come in either a Kan or OTG. The Maui Punch, Swiss Cacao and Raspberry Lemonade (once it’s released) are only available in OTG envelopes. The Orange is great because it contains MCT, however if you’re in a lot of pain you might consider the Chocolate Swirl – it contains a short fatty chain butyrate which is really good for inflammation. My fibromyalgia customers use that one mostly when in a crisis. They all work….there’s just some differences. Let me know if you have more questions or you can email me directly at [email protected] Pruvit is on sale today 20% off. Thanks! Rachel

      Rachel Vrabel August 2, 2017 at 9:52 pm - Leave A Comment

      Hi Lucretia, you’re more than likely dehydrated, so definitely up your water intake to half your body weight in ounces.Remember ketosis flushes the body of water so with that goes electrolytes. Good to add a little Himalayan salt to your foods and/or a magnesium supplement. If you also changed your diet to a low carb diet, that could be a contributing factor, but Ketones themselves should not cause a headache. Good luck! Rachel

    Hi Rachel!
    I started out on Herbalife in January and lost 25lbs. in 4 months, but have plateaued the last 3 months. Thinking maybe my body has just gotten accustomed so I’ve been looking at ways to shake/shock my body and start losing weight again. I’m interested in trying Keto-OS but it’s super expensive and I’d rather try before I buy. I saw you had offered samples to some people and was wondering if you’re still doing that? And if so, may I try some?
    Thank you!

    I am trying to take the Decaf Orange Keto OS. I started taking one in the mid morning after I have my caffeinated coffee. 30 minutes later, I want to take a nap. No energy at all. It does help with my constipation, which is good. That being said, if I am staying at home, I do take it before bed and it does help me sleep. As for energy or Ketosis (I have the sticks) have not seen any of that. I also do have to add that I have not started a routine due to the fatigue and what my plans are for the day.

      Rachel Vrabel July 9, 2017 at 7:16 pm - Leave A Comment

      Hi Irma, I would definitely recommend drink the Charged for your morning dose. If you’re a coffee drinker already, I doubt the caffeine in the charged will be too much. It’s got about as much as a cup of coffee. The MCT powder in the orange also makes you feel more full which is great for suppressing appetite but it sounds like it’s just making you sleepy. Test with the sticks 30 minutes after drinking a full serving, you will see it register on the stick. If you wait for hours to test, it could be out of your system by then. Good luck! Rachel

    I have hypothyroidism which means I have an under active thyroid. My metabolism is slow as a result and I have a sensitivity to caffeine. Do you have any info regarding results with people having metabolism issues? I also would like to know if the decaf products are as effective as those containing caffeine?

    • Rachel Vrabel
      Rachel Vrabel June 20, 2017 at 7:28 pm - Leave A Comment

      Hi VM, thanks for your message. Keto can help with thyroid and boosting metabolism. If you have the time, watch this FB live video with Dr. Heather Carden. It’s on the JustPruvit corporate Facebook page, so you may have to “like” their page first. She is super informative on all things Keto OS and she also talks about thyroid….it’s a 30 minute video and I’m sorry I don’t know exactly at what point she discusses thyroid, but it’s worth listening to and will probably answer a ton of other questions you may have. The decaf works just as well to put you into ketosis. You won’t get the caffeine “buzz” but you’ll still get mental energy and increased focus since the brain loves ketones, so you’ll still get some energy from it as well. I’ll also link you to the Pruvit Research section, if you scroll all the way down the page, there are a ton of great articles. Let me know if you still have questions. Thank you, Rachel

    Thanks for this great information. But, please stop saying that muscle weighs more than fat. A pound is a pound is a pound. Whether it’s a pound of feathers, a pound of lead, or a pound of muscle. Muscle is more DENSE than fat, so it takes up much less space, but it still weighs 16 ounces…and so does a pound of fat.
    Your review was great otherwise. Thank you!

I don’t remember that…some people do take longer however, depends how bad your diet is and what you’re used to eating. My sis did have an upset stomach for a couple days from the Orange Dream and then she was fine. Rachel

          A few days….a week. I don’t feel that was a glaring discrepancy or intentional to mislead anyone, my point was that if you do get an upset stomach (which most people don’t at all by the way), it usually doesn’t last long, but everyone is different. If you are concerned about the orange giving you an upset stomach, or you’re sensitive to fats, the chocolate is the one I recommend because it doesn’t contain MCT oils and contains a prebiotic. Hope that helps. Rachel

    Tonya, I just want to say – I love you! 🙂 I really appreciate your comment and support on this, you totally made my day – thank you! Pruvit is an MLM, so you do have to know someone if you’d like to purchase it, so why not from me? I promote it because I LOVE the product for so many reasons and I don’t hide the fact that I’m a promoter – I’m very proud to be! Some people are just miserable and love to complain. The same woman started commenting on a bunch of other posts so I decided to take the high road and ignore any more communication – just a Negative Nancy. I’ve worked hard on this blog for six years to make it what it is today and feel good about my recommendations. Thank you again for your encouraging support! ~Rachel

    Hey Rachel – you mentioned dealing with IVF and pregnancy loss, I’m in the same boat. I’ve done 1 retrieval and 3 transfers ending in 2 miscarriages and 1 failed cycle. Same as you experienced my body is kind of a wreck from all of it. I’m doing another retrieval in May and a transfer in August. Have you done Keto os while doing IVF cycles? Did you ever talk to a doc about it? I’m curious to try but I also don’t want to anything that may have a negative impact on our IVF.

      Hi Casey, thanks for your message. I’m really sorry for your losses, I know how painful that is…I’m not sure how being in ketosis would affect a cycle. I wouldn’t recommend drinking in once you start injections, but I don’t see any reason not to use it to your benefit up until then. It’s very safe in fact it’s safe for pregnant and nursing mothers. And for what it’s worth, drinking keto makes me feel happy again, I am seriously always in a good mood. I was extremely low after more than a year going through 3 cycles of IVF, so it definitely has made me feel like my happy, energized self again! You could talk to your Dr. about continuing on it once you start your meds (like decaf) but most Dr.’s like to say don’t add anything to the mix once your stimming. Good luck with your next cycle!! I know it’s so rough! Rachel

    Hi there,

    I just started taking this product this week. I am very active and at an ideal weight but am doing this more for energy and focus. I work out at 5am (HIIT and weights) and do my coffee post workout and then my keto OS chocolate swirl at 8am. My struggle is that I am usually hungry by 9-10am. Am I decreasing the effectiveness by eating so soon after? It is 3 whole eggs and cauliflower rice so still keto but I am wondering if this is okay or if I should switch the time I take my keto OS.

    • Rachel Vrabel
      Rachel Vrabel March 21, 2017 at 7:17 pm - Leave A Comment

      Hey Sarah! Thanks for your question. You won’t decrease it’s effectiveness but if you want to do more of an intermittent fasting method, try drinking your keto in the morning before your workout and keeping everything else the same. You may not be as hungry so quickly if your goal is to wait a little longer to eat. Also, you’ll have a lot more energy for your workout! I realize this means probably drinking it at 4:30 and finishing up on your way to the gym but I love the maui as a preworkout. Sometimes I’m not quite finished with it yet and I’ll finish the rest during my workout, adding a little more water along the way if I’m thirsty. If you’re doing this more for the energy and focus, just give it a try pre workout one day and see how you feel. Either way is great! Personally I don’t really eat for several hours at least after I drink my keto….I like to be fueled by the ketones alone for a while because I feel great when I do that. Good luck and keep me posted. I’d love to hear how your workout is fueled by keto! 🙂 Rachel

    Tried it for the first time today. My friend swears by it and sent me samples. I am experiencing the worst stomach cramps ever. I tried advocare products in the past and it didn’t help. I was able to lose almost 40 on my own without suplements and keep it off for about a year but then started regaining and hit a plateu so tried this. I don’t think I will continue.

      Hi Valerie, are you drinking the Orange Dream? That is only flavor that contains MCT oils which for some can cause some stomach upset. It should pass if you’re able to push through it, but this is the only flavor I’ve ever heard of giving anyone stomach upset. You should try the chocolate flavor – it includes a prebiotic and anyone that has a reaction to the orange is better suited on the chocolate. You can email me at [email protected] if you’d like to talk more about or privately. Let me know if it’s the orange. Thanks! and I’m sorry…my sister had an upset stomach for a couple days on the orange but then it passed. Your body is adapting but I would recommend chocolate for you.

    Hi Rachel! Thanks for the review, very informative. I already purchased some Keto Kreme and the Max but then read somewhere that the Ketone OS stuff isn’t in the kreme?? So if I drink the Kreme in the morning with my coffee, I’m still going to need to take the Max in the morning as well? I was planning on Kreme in the morning, Max in the late afternoon before my workout.

      Hi Tonya, thanks! You’re right, the Keto Kreme is a companion product just to get a nice healthy fat serving, it doesn’t contain ketones like the other Keto OS flavor (max, orange and chocolate). You can drink that in your coffee in the morning (or make pancakes with it for a meal), and then normally you’d want to drink your Max a short while after that. The keto kreme will help keep you full and rev your metabolism but it’s not going to put you into ketosis like the Max would. Personally, I would drink some plain water after you have your coffee with Keto kreme and then I’d drink a full serving of the MAX so you’ve got energy throughout the day and you’re burning fat. Then I would drink another half serving of the charged by 3 for energy for your workout if you feel you need an energy boost. This is exactly what I do most days. I’ll drink another half serving of the charged if I’m going to Orange Theory class or I’ll drink a whole decaf. I would not delay drinking your max until late afternoon. You’ll miss out on the all day energy and focus, fat burning, and it could keep you up because of the caffeine. Let me know how it goes! Rachel

    Thank you for reviewing this product. I just ordered the chocolate swirl for a.m. and caffeine-free for p.m. I attempted to follow the keto plan back in early December and while I lost 5lbs, it was hard for me to reach ketosis. I’m excited to give this a try and will follow the low-carb lifestyle.

      Deanna, thanks for your message. Following a strict ketogenic diet is very difficult, if not impossible for most people. This is where Keto OS is really going to make things a lot easier for you to stay in ketosis! And if you follow a low carb diet, you’re going to get great results. Even if you cheat with extra carbs, the Keto is going to stay in your system and keep you in ketosis for up to 24 hours. Best of luck with it and I’d love to hear back from you to see how you like it. ~Rachel

    Hi there, if I exercise in the afternoons is it ok to still have the keto OS in The morning? Or should I have it an hour before training? Do you know how long our body stays in ketosis after having the supplement?

    • Rachel Vrabel
      Rachel Vrabel January 16, 2017 at 6:11 pm - Leave A Comment

      Hi Lisa, absolutely it’s great (and best) to start your day by drinking Keto OS. If you’re drinking it early (between 7 and 9am) then you should have a second serving in the afternoon (between 1-4) and then go train. If you drink two servings per day your body will stay in ketosis for up to 24 hours. You can drink the decaf in the afternoon if you’re sensitive to caffeine or you find you have any trouble getting to sleep. I’m usually ok as long as I drink it before 3. Good luck and let me know if you have any more questions. ~Rachel

    Hey John, I appreciate your comment even if you are giving a huge thumbs down to Keto OS. Kudos to you for losing 100 lbs! I’ve never been able to stick with a ketogenic diet, it’s extremely difficult. Like you said, even more restricting than Atkins. I disagree with you that 10 lbs in 3 weeks is not great progress, at least for me. Being only 10-15 lbs away from my goal weight, it was much harder to lose. I think it’s a pretty well known fact that those last 10 lbs are the most stubborn. And if you have a lot of weight to lose, as you did, then I could see losing 10 lbs in a week of water weight. Losing 10 lbs in a week for someone like me would be completely ridiculous, impossible without starving myself, and losing 10 lbs in a week is not even recommended. Losing 2-3 lbs per week is a reasonable amount for me to lose safely and effectively. You’re right that Keto OS can help with alzheimer’s, there’s a lot of research on the Keto OS website about it in their research section. Obviously, trying to eat clean while consuming Keto is the way to go. This supplement isn’t a miracle drink, I always recommend trying to eat a healthy diet and exercising to achieve your overall health and fitness goals. I think of this supplement as a boost, a boost to get off my ass when I don’t feel like going to the gym, an energy boost to power through workouts with more energy, focus and less inflammation afterwards, a little help to suppress the appetite when I feel like stuffing my face with cheese and crackers, and it does help your body burn fat quicker. This all still takes willpower, determination and a huge desire to better myself. I know I’m getting off track, but to me Keto OS is not “snakeoil” and I would probably not enjoy drinking a $3.99 jar of coconut oil 😉 Anyhow, it’s not for everyone but it’s helped a lot of people, including me and my sister… But I do appreciate you taking the time to comment. I don’t just approve “the good comments.” I feel there is value in these discussions. Have a great day and keep up the good work with your weight loss! ~Rachel

    I am concerned about the use of Keto OS (I ordered the chocolate swirl w/ caffeine for myself) for my husband who has diabetes. If the product is getting you in ketosis (more ketones) would this be dangerous for a diabetic? I need to lose 40-45 pounds myself, have no thyroid due to thyroidectomy bc of thyroid cancer, so I’m hoping this will help me loose the weight as nothing else has helped me significantly.

    • Rachel Vrabel
      Rachel Vrabel December 5, 2016 at 12:01 am - Leave A Comment

      Hi Sherri, thanks for your question. I want to refer you to the Research section of the Keto OS website. Scroll all the way to near the bottom until you see the section called “Still Wondering?” and there is a section under this called “Improving Insulin Insensitivity.” This is where you can read the Pub Med research regarding a ketogenic, low carb diet and its affect on insulin. Keto OS is not a replacement for a ketogenic diet but a supplement to help you stay in ketosis. It should not be dangerous for a diabetic, in fact it should help, but you should always check with your Doctor before starting a new supplement, especially if you’re on other medications. As far as it being safe for you with no thyroid, it shouldn’t be a problem for you. If you decide to try it, both of you should start very slowly, only drink one half of a pack (each) per day mixed with water. See how you feel on it for several days, 4-5 days before you drink a whole pack. If your husband checks his insulin he should keep a close watch on it for any changes. I would still recommend talking to your Doctor first. Good luck! Rachel

      Carro, you can take it to reach your desired weight, and then stop. However, just like with any diet plan – if you go back to eating bad you’ll gain weight back. Some people like the other health benefits of Keto OS so they continue drinking it long term. It has a lot of other benefits besides weight loss such as energy, mental focus, fights inflammation and protects the brain. But you can certainly just drink it for weight loss. Rachel

    Hi! This question is kind of more for your sister. I’m also epileptic and have been struggling with the keto diet for a while. I was just wondering if the keto os has been successfully keeping her body in ketosis and if it has helped decrease the number of seizures she’s had. I appreciate any kind of response you can give me. Cheers!

    • Rachel Vrabel
      Rachel Vrabel October 31, 2016 at 4:09 pm - Leave A Comment

      Hi Catherine, thanks for your email. I’m sorry you’re dealing with epilepsy, it’s a very difficult road at times. The Keto OS had no effect on her seizure activity that we could tell, since she’s been seizure free for about 5 years from finally finding the right cocktail of meds (thank God). She hasn’t been drinking it every day since she lost some weight. She drank it pretty faithfully to lose some weight, and then she really upped her yoga activity so that’s been keeping her on track for the most part, although she’s gained back a few lbs so she’s been wanting to restart the Keto. She always did real well tolerating it and never had any side effects. As far as using it to stay in ketosis long term, I think you certainly could, but I don’t know that it “replaces” the ketogenic diet that Dr.’s recommend for epilepsy, in fact I know it doesn’t, it’s more of a supplement to the ketogenic lifestyle. It’s always best to talk to your Dr. about starting any new supplements when you have epilepsy, so I would just run it by him/her for some guidance. Good luck to you! Rachel

    Hi, I was on their website and I don’t see the sample pack option anywhere. So I’m guessing they no longer offer that??? I really want to try this but is too expensive for me. ?

I would recommend ordering a 15 pack of either the Orange Dream or the Chocolate Swirl to try it. They have a money back guarantee with good customer service so if you try it for several days and don’t like it, you can call and tell them you want to return it. They stand by their return policy 100%, but I guarantee you’ll love it! Rachel

So at that point, I started drinking it again. This is a great product that works! Good luck, Rachel

      Hi Elizabeth, no the Chocolate Swirl Keto OS does not give me the shakes at all, nor does the Orange charged. It has about as much caffeine as a cup of coffee but it gives me more of a steady all day energy rather than a quick, jittery buzz. That’s what I really like about it. You could always order the smaller package to make sure you like it, but they do offer a money back guarantee, just to let you know. Great company and customer service. Good luck! I can’t say enough about the effectiveness of this product, it really works for weight loss, energy, and mental focus. Rachel

    Hi Rachel, wondering what is the exact difference between the original Keto-OS and the new product. Are they both as effective? Appreciate your input. Have had the product for over a year and started taking it but didn’t notice much change and felt nauseas so stopped it. I had bought the 300. supply when the company was just taking off. So I have quite a bit of it left. Wondering if I should give it another try. But I’m curious as to the changes they made in the newer version and the difference in the effectiveness if any. Thanks for all the info you share.

    • Rachel Vrabel
      Rachel Vrabel August 30, 2016 at 8:05 pm - Leave A Comment

      Hi Deborah, thanks for your question. There is a difference between the old Orange 2.0 and the new Orange Dream 2.1. They changed the ratio of the salts and the MCT powder and added a few things. I’m going to link a picture here of all three showing the ingredients on the back of the packets (Orange 2.0, Orange Dream 2.1, and Chocolate Swirl 3.0) so you can see the difference. I can only say they have improved the formula based on their science and research.

      The new Chocolate Swirl 3.0 has a much different formula, and I just got mine (it’s delicious!). You may do better on the chocolate since they added a prebiotic and it’s supposed to not give you an upset stomach. I’m going to copy and paste here a clip from my review that talks about the new 3.0:

      What’s Different about Chocolate Swirl 3.0?
      -Ratio of BHB salts for faster peak into the system which creates sustained ketone levels throughout the day
      -Added Ketogenic Amino Acids and Short Chained Fatty Acids which use the same transporters as ketones so you’re getting that same direct quick uptake into your system
      -Includes a Prebiotic – a food source for the good bacteria in the gut making them stronger and more able to fight off the bad bacteria and also helps with gastro intestinal upset
      -Vegan, Dairy and Gluten Free so now there’s a product suitable for everyone.

      You can read more about the Keto OS 3.0 Chocolate Swirl by clicking here.

      I’d hate for you to waste all that orange you have. You could give it another try. Try drinking half a pack for a few days, then go to a full pack. Did you start slowly last time? It’s very important. You should get over that stomach upset fairly quickly, that’s your body getting used to the MCT oil. I never had an upset stomach but my sister did, but only for a day or two.
      Let me know if you have any more questions, and good luck!

    I have the original Keto OS. I heard that if you drink coffee before taking it, then it won’t work. Is this true? I need to lose 50 lbs, but the very first thing I do in the morning is have a cup of coffee. I don’t want to waste the Keto OS. But I do want to start taking it.

      Hi Susan! This is not true. This is exactly how I drink it. When I wake up, I drink my coffee and use cream in it (no sugar), then drink one plain glass of water, then drink the Keto OS and it takes me about 45 minutes to drink it slowly. I still have a bunch of the old formula that I’m using as well, nothing wrong with it. My next order I’m getting the 3.0 Chocolate Swirl though! If you put a lot of sugar in your coffee, that will hinder weight loss but the Keto will still work. Good luck!

    Just wondering…do you feel/believe/think that this is something that you will have to continue to take for life, like for maintenance? or is it a shorter term thing, like when you reach your goals, then you discontinue? I have looked for an answer but haven’t been able to find one…

    • Rachel Vrabel
      Rachel Vrabel June 10, 2016 at 2:56 pm - Leave A Comment

      Lisa, you don’t have to drink it for life. It’s a great weight loss tool to reach your goals. Some people like the energy and continue at smaller doses. But you could certainly take it for a few months, lose weight and then stop. The only thing that will cause you to gain the weight back is if you go back to an unhealthy lifestyle to be totally honest. I’ve taken it and lose weight but also taken breaks from drinking it and haven’t gained any weight back but I have to continue to eat fairly clean and stay active. 🙂 I just started drinking it again because I like the energy and I want to lose another 5 lbs. it also helps me to be a lot less sore between lifting weights and volleyball since it helps with inflammation.

      Helen, there is no special diet. That’s why people are raving about this product! They do have some information on their website about pairing it with a ketogenic diet (moderate protein/low carb/high fat) for optimal weight loss, but you don’t have to. Keto suppresses my appetite like crazy so you won’t feel hungry.

    What’s the best type of diet while on Keto?

    • Rachel Vrabel
      Rachel Vrabel April 6, 2016 at 5:24 pm - Leave A Comment

      Hi Neal, that’s awesome! You’re going to love it. The best diet to combine with Keto-OS is to follow a ketogenic diet, and there’s a ton of information and links if you look around on the Keto website: Moderate protein/low carb/high fat (good fats mostly). This is what brings optimal weight loss. But I wouldn’t go nuts with it….try to eat clean, no processed foods, no white flour, no alcohol, no added sugar or fake sweeteners. Add some good fats such as salmon, avocado, drizzle olive oil on steamed veggies or salad (oil and balsamic on salad), hummus and veggies, small handful of nuts. These are the things I eat when I want to increase my good fats. You can also cook your eggs and stir fry veggies in coconut oil. If you like smoothies, add some flax seed oil or ground flax seed, that’ll add some good fat too! Good luck and keep in touch. Let me know if you have any more questions. Rachel

    Hi! I’m only on day 4 of drinking 1/2 a pkg of Keto in the AM (upon waking) and the other half later in the afternoon. Yesterday and today I’ve noticed a lot of stomach upset and not feeling the best. It kind of feels like what your stomach would feel like when it’s empty and hungry – with a lot of gurgling and growling, yet I don’t feel hungry. I’m just wondering if this will pass. I like that I have more energy and it’s definitely hunger suppressing. I’m just not enjoying how much stomach feels these past 2 days.

    • Rachel Vrabel
      Rachel Vrabel March 22, 2016 at 7:18 pm - Leave A Comment

      Hi Loretta, thanks for your question. Tummy upset can happen in the beginning but it should pass. My sister had that experience when she started and it passed after about a week. Honestly from what they explain on the website, it’s your body getting used to the high fat content (the MCT oil) which is extracted from coconut. Did you start by just drinking half a pack a day for at least four or five days? You could always taper down to half until this feeling passes and then go up to a full pack. It’s also my understanding that the more gut issues you have, the more upset tummy you’ll have. So it’s probably not a bad thing entirely if that makes sense. Good luck!

      • Loretta March 23, 2016 at 11:55 am - Leave A Comment

        Thank you very much for your response! I was doing 1/2 a pack in the AM and half in the PM, but yesterday I only did 1/2 the pack. I’m on day 5 now. I have always had other stomach/digestion issues so that would make sense as to why I am now. 🙂

      Reba, Keto should keep you in ketosis for up to 24 hours. Half a pack won’t though, that’s just the starting dose to get used to it. Some people need to drink up to two packs per day for optimal ketosis and weight loss. Honestly I never did the pee strips, and I only drink one pack per day. I never took two since I didn’t have as much weight to lose and one works for me for weight loss and energy. Try going up to one pack and test again.

    Hi, Rachel, I just got totally engrossed by your review of the Keto OS. This sounds like a product that would be my saving grace! I am, like the Dr. says “morbidly obese”.. those are such dirty sounding words.. and honestly makes me want to cry even now as I write this message. How could let myself get to this point??..I have also just been diagnosed with type 2 diabetes.. my Dr. wants me to have lap band surgery.. for quicker results.. although there are lots of hoops to have to jump through to even get that surgery approved through my u think a person such as myself could benefit from this product?.. thank you for listening.. and good luck to you and your sister!

      Carmen, thank you so much for your email. I’m so sorry, I know it must be upsetting to feel the way you are right now, but you can change it! There is always hope and I would want to try everything before I resorted to surgery. I think Keto-OS could absolutely help you. Not only to lose weight, but to help with your diabetes. This is an excerpt from the website regarding insulin resistance and how keto can help.

      KETO//OS can enhance insulin sensitivity. In preclinical studies, exogenous ketones have been shown to do this. Richard Veech (scientist at the NIH) showed that feeding exogenous ketone supplements lowers blood glucose while simultaneously lowering blood insulin “research has demonstrated “ If more glucose is removed from the blood with less insulin that suggests that insulin sensitivity has been enhanced. We are experiencing this from testimonies of KETO//OS. As with any medical condition we recommend you consult with your physician.

      If you go to the home page of Keto-OS and scroll down all the way until you can scroll no further, you’ll see the “FAQ” section. This is where I quoted from, one of the questions. If I were you, I would get started right away, for your health and for your well being. I have seen some amazing results from some of the other posters, in fact one of the guys who started Keto was “morbidly obese” and that’s one of the reasons he wanted to get this product on the market. It’s very safe and it works quickly. You don’t “have” to change your diet, but it would always be of more benefit to eat clean while taking the keto. You don’t have to go nuts and follow the ketogenic diet (they recommend it) but that’s the beauty of this product – you will still go into ketosis within 15 minutes and stay there for 24 hours.

      There’s a lot more I could say, but you’ve read my review. I would encourage you to browse the website some more and watch some of the videos. Yes, it’s a bit pricey, but this is your health…there’s no price you can put on that in my opinion.

      I’d be happy to help you along in your journey, in fact I would love for you to try it and see how you like it. Be sure and keep in touch!

      Stacy, thanks for your question. I KNOW this product will work for you. I’ve seen it changing many lives! With not a lot of time to work out, it’s easier to lose weight by diet/supplements, but even those 1-2 days of exercise can always help 🙂 To answer your question, I would start with buying a Go Pack since this is the best bang for your buck in the long run, and I know you’re going to like it and see quick results. Start by drinking half a packet for a few days to see how you feel, then go up to a full pack. You could drink one a day in the morning and see results, but if you want quicker results, you can drink up to two per day, but one is working for me! You don’t have to change your diet, but a ketogenic diet would melt the fat off even quicker. I haven’t adapted it yet, but Keto-OS does recommend it for best results. Good luck!

      Hey Lauren, thanks for your question. I drink my coffee first thing in the morning (well actually around 9 – I have a very late schedule), drink a glass of plain water, then drink the Keto-OS, then I eat around noon.

      This is more of the “intermittent fasting” method, however Keto-OS can be taken on an empty stomach or with food. You will still go into ketosis.

      I’ve also done it where I drink coffee, drink a green smoothie or eggs and toast for breakfast, then drink the Keto.

      I would recommend you read the Frequently Asked Questions (FAQ)- scroll down to the very bottom of the Keto website and it’s under Questions/Browse FAQ. There is some great info there!

      Would you like a sample? I’ll send you a separate email! 🙂

      Alana, thanks for your comment. No doubt Paleo can work if you can work around the food restrictions i.e. mostly meat, fish, vegetables, and fruit, and excluding dairy or grain products and processed food. I’m not knocking it, but a lot of people don’t want to have to eat such a strict diet. 😉 Keto-OS brings an alternative to that, and it also has so many other health benefits. But that’s some awesome weight loss you’ve accomplished, congrats!
