Back to My Pruvit Keto OS Review – But That News Couldn’t Wait!

Keto OS review

Pruvit Keto OS Flavors – Taste the rainbow!

Hello! Today I’m reviewing a supplement called Keto OS, which is a powder you mix with water and drink twice daily that throws your body into a fat burning state of ketosis within 30 minutes.

What is ketosis? Ketosis is when your body is burning ketones for energy instead of glucose (carbs/sugar).

The skinny is – you’re burning FAT rather than carbs. Good for weight loss? Heck yes! And extremely safe, by the way.

Remember the Atkins Diet – high fat, low carb? A freaking miserable diet if you’ve ever tried it, but one that works to shed weight quickly if you can endure the food restrictions.

A similar diet is the Ketogenic Diet which is a high fat/moderate protein/low carb diet (and by low carb I mean less than 5% carbs per day!) and there are plenty of restrictions – it’s similar to the induction phase of Atkins.

  • But what if you don’t want to follow a strict diet but you still want the fat burning/weight loss benefits of being in ketosis?
  • Or what if you’re following a ketogenic diet and you’re having trouble staying in ketosis? Or want to be able to cheat and live a little?

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

Why Am I Writing About Pruvit Keto OS?

The reason I chose to review Keto OS is because my sister 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.

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 so many meds that cause weight gain!

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?

how does keto-os taste

Keto OS Orange Dream with lemon

Prüvit’s KETO//OS (Ketone Operating System) is a proprietary formula which delivers ketones into your system and allows you to “Bio-hack” your own body to go into instant ketosis to lose weight. 

Keto OS contains a patented and proprietary engineered ingredients formula of ketone mineral salts and fat sources for optimal protein synthesis that equals high energy fuel, and the recommended dose is to drink it twice per day.

Ketones produce 38% more energy than glucose (carbs/sugar).  Ketones are the ideal choice to fuel the body with more power by burning fat.

The brain absolutely loves ketones, 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 (more on that later). 

Normally, ketones are only produced in the body during periods of fasting, but when’s the last time you fasted?

What is Ketosis?

When we were hunter-gatherers, we would go into ketosis and burn fat instead of muscle until we found our next meal.

Ketogenic diet

Ketogenic Diet

But think about it – when’s the last time you had to endure a prolonged period of fasting? Give up pizza or bread? Yea, never, let’s be real!

We are a carb-loving society for sure, and that’s why our waistlines have gotten out of control.

Metabolic syndrome is projected to surpass cigarette smoking as the leading factor for heart disease. Obesity and lack of activity are to blame.

We, as a population (me included) love all the carbs that are so abundant. We don’t eat enough good fat (salmon, avocado, omega 3’s) and we surely don’t eat enough veggies and fruit.

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 Keto OS twice per day can allow your body to safely go into ketosis and burn fat for fuel without having to follow a strict diet.

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.

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

Many people ask me how to take Keto OS, and this is my recommendation:  Drink Keto OS and a new diet will follow naturally – because you won’t be as hungry or have carb cravings!

The folks at Pruvit recommend a ketogenic diet for optimal results (low carb/high fat), but you certainly don’t have to follow this diet for Keto OS to put you into ketosis and provide results.

If you’re following a ketogenic diet already and have trouble getting into or staying in ketosis – drinking Keto OS can help you stay there.

If you want to cheat with carbs now and then, you will stay in ketosis if you’re drinking Keto OS. In other words, live a little while staying on track which is what I do!

I eat carbs and I’m still losing weight! Some days I’ll have a protein shake with blueberries and ground flax seed, and when I do eat carbs, I try to focus on eating good carbs like sweet potato. But sometimes I’ll eat a sandwich, or a slice of pizza! Gotta live!

How Do You Drink Keto OS and What Does It Taste Like?

Keto OS Orange Dream Version 2.1


Keto OS Orange Dream 2.1

Keto OS came out with the new new Orange Dream 2.1 version in April 2016 which is a newer, more optimized version. Here’s a picture of the Orange Dream Ingredients.

The Orange Dream Keto OS comes in two versions, the “Charged” version, which has about the same amount of caffeine as a cup of coffee (120 mg), and the “Non-Charged” decaffeinated version (all the flavors have Charged and Decaf versions).

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

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

The recommendation (and what I did at first) is to start by drinking one-half of an envelope in the morning per day to allow your body to adjust to it for a few days, then drink a whole one each morning.

Once you do that for about a week, you can add the afternoon serving.

What I normally do is get up, have a cup of coffee with cream, then drink a plain glass of water, then drink a full serving of Keto OS. Then I don’t eat breakfast until I’m hungry!

Then usually around 3 or 4 is when I drink my second serving. If I’m doing an afternoon workout, I will usually drink another charged – Keto OS, especially the Maui Punch flavor, it a GREAT pre-workout. If I’m not working out, I’ll drink a decaf.

Keto OS Drink Recipes

Keto tastes really good mixed with a sparkling water, like La Croix! The Keto OS website offers some fun recipes you can whip up with your Keto powder.  My favorite is the Maui MaxTai and here is the recipe:

  • 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!

New Flavor: Keto OS Chocolate Swirl Version 3.0


Keto OS Chocolate Swirl 3.0

Keto OS has just unleashed a new flavor in a new 3.0 edition of Keto OS – Chocolate Swirl! And with it, a new and improved formula. Here’s a picture of the Chocolate Swirl ingredients. It tastes just like a tootsie roll!

They’ve added a prebiotic to the Chocolate swirl, so if you have any kind of gut issues then I would recommend the Chocolate swirl.

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.

Keto OS Bio Max Maui Punch Flavor – Most Advanced Version

why is keto os bio max better

New Keto OS Bio Max

*UPDATE 1/10/17* I just got the Bio Max Maui Punch today!

I tried the Bio Max this morning for the first time and it’s hands down my favorite flavor – it tastes just like Hawaiian Punch! It’s lighter than the Orange and it’s very easy to drink.

The Bio Max has the most pure, most bio-available form of ketones, meaning your body can absorb it better.

Bio Max is gluten-free, dairy-free, Vegan and Kosher Certified (like the Chocolate) and is the most advanced ketone delivery drink they offer.

After a week on the Maui Punch, I’ve lost 6 lbs!!

This stuff is absolutely amazing. I’m energized all day, and I have so much motivation to work out and eat healthy. I have to remind myself to eat since it suppresses my appetite so much.

keto os resultsCurrently I’m drinking a Maui punch charged in the morning and another half serving in the afternoon, or a whole decaf.

**UPDATE 1/24/17** Still going strong!! Down 7 lbs and I’m toning up! Check out my latest pic.

This latest picture of me was taken a couple days ago and you may have seen my instagram post (follow me @womensblogtalk).

I bought these shorts in my “old size” as motivation and I’m fitting into them now! *high-fives*

**UPDATE 2/10/17** Lost a total of 10 lbs! Check out my before and after pictures towards the bottom.

Keto Kreme – Healthy Fat Source for Your Coffee

Keto Kreme review

Keto Kreme mixed with hazelnut coffee

Pruvit offers a companion product called Keto Kreme which is a powder you mix with your coffee or other hot beverage. Here’s a picture of the Keto Kreme ingredients.

This is their version of “bulletproof coffee” which is pretty much a staple with a ketogenic diet.

It contains a healthy serving of FAT, yes fat (16 grams). Fat burns fat. Keto Kreme is made from coconut oil, MCT Powder and is sweetened with stevia and also contains cinnamon – yum!

I add it to my hazelnut coffee sometimes and it’s delicious!  If you’re following a ketogenic diet, this is a GREAT addition to get a healthy serving of good fats which will rev up your metabolism.

If you’re more focused on weight loss, drinking a cup of coffee with the Keto Kreme is going to really fill you up, and help your body to burn fat.

Follow the Keto Kreme with a serving of Keto OS and this is great way to really kick your weight loss into high gear. I do this at least 3-4 times per week!

But remember, the Keto Kreme doesn’t contain the ketone blend like the other flavors, this would be in addition to the Keto OS, or, if you’re just looking to get more fat in your diet.

Keto Kreme Pancakes

My sister and I made some Keto Kreme pancakes the other day and they are amazing!

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

So easy and quick! Here’s me and my sister making pancakes the other morning. Yum!

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 Keto OS 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 or feeling sick 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.

My sister had an issue for a couple days but it passed, and I did feel nauseous a couple times while drinking the Orange but it didn’t last and it was completely random (not at the beginning). Your body should adjust! This is called “keto-adaption.”

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, so be sure and drink plenty of fresh water throughout the day! (half of your body weight in ounces if you can).

How I’ve Felt on Keto OS

What I’ve felt since I started drinking Keto OS 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.

I haven’t even been drinking my afternoon cup of coffee at all. I just don’t get tired so I don’t crave it.

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!

I want to add that it’s a very level feeling of energy, unlike coffee where you might feel pepped up for a little while but then crash. Ketones are brain food – my brain is so much more sharp!

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 ass 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!

How Much Weight Have I Lost on Keto OS?

keto os before and after photos

Feeling kinda shredded after a few weeks on Keto OS! 😉

I have lost a total of 11 lbs! Why is this huge for me? Well, over the past year I gained about 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. I have never “not” been able to lose weight if I tried, but no matter WHAT I did, the scale did not budge. For months!! It was very discouraging and I didn’t feel like myself.

However, after starting the Keto OS I have found that I’m losing weight easily and never hungry! It does suppress your appetite and what I’ve noticed is that I’m not snacking anymore at night and a smaller meal fills me up.

It’s harder to lose weight the closer that you are to your IDEAL weight. So that’s why this has been such a big score for me personally.

So if you have a lot of weight to lose, Keto is going to make it real easy!

If you have more than 10 lbs to lose, be SURE and drink 2 servings per day so that you stay in ketosis for 24 hours – you’ll be burning fat while you sleep!

My Keto OS Before and After Photos

Keto OS before and after photo

My before pictures were taken four weeks before my after photos. So in 4 weeks, I’ve lost about 11 lbs total. Whoop!

You can tell by my photos how my body composition has changed. I have replaced fat with some muscle and I’m a lot less bloated.

I lost the most weight around my middle, my back, rear end and top of my thighs.

My face is slimmer, less puffy and my skin looks great!keto os results

I’m happy because my love handles are gone and I can fit into my size 6 skinny jeans again!

Keto OS N8TIVE ZONE – For the Hardcore Athletes

If you’re reading this and you consider yourself more hardcore, i.e. you’re a weight lifter, crossfitter, triathlete, 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.

I have been doing Orange Theory HIIT training 2-3 times per week and my workouts have never been better!

One of the best ways to boost weight loss and lose body fat is to drink a Keto OS (Maui for me) in the morning and do a class or a workout in a fasted state fueled by ketones!

Your body will NOT feel low on blood sugar because you haven’t eaten – you will feel powerful and strong and get shredded!

What Other Ailments/Illnesses Can Keto OS Help With?

Aside from the obvious weight loss benefits, Keto OS has 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 trying to say Keto cures cancer, because it does not, only that cancer cells don’t thrive in ketosis).

Keto OS has been seen on ABC, NBC, Fox news, and studied at Yale University and Oxford. Keto OS is lab tested, Doctor approved, has its CFA (Certificate of Analysis) and has a patent on its proprietary formula.

Where Can I Buy Keto OS & How Much Does it Cost?

Pruvit Keto OS review

Pruvit Keto OS – there’s a flavor for everyone! 🙂

The only place to purchase Keto OS is online from their official website and it comes with a 100% 90 day money back guarantee – basically risk free!

The cost varies depending on how much you buy, and if there’s one drawback to this product, it would be that it’s a bit pricey! But you can’t put a price on your health, or your self confidence!!

The Smartship option does provide 17% savings – this is where they’ll automatically send it to you each month. This is the best deal, and you can cancel anytime.

NOTE ON SMARTSHIP: If you sign up for smartship, it ships monthly and it will show you the next ship date (about a month away).

So if you sign up for smartship, I recommend doing a one time order as well so that you’re not waiting for weeks to get started!

A one time order you’ll receive in about 5-7 days via UPS and you’ll also get it at a discount since you’re setting up smartship.

So when you go through checkout, what you want to choose is “today and smartship.”

With each package, you’ll pick which flavor you want, and whether or not you want the charged or the non-charged.

  • 15 servings (OTG) = $85 ($76 w/Smartship)
  • 30 servings (OTG) = $160 ($144 w/Smartship)
  • 30 servings (Kan) = $144 ($133 w/Smartship)
  • 60 servings (Kan 30 + OTG 30) = $300 ($255 w/Smartship)
  • 90 servings – *Family Pack (90  OTG Mix Pack, Orange Dream & Chocolate Swirl) = $408
  • 200 servings – *Experience Pack (200 OTG Mix Pack, 80 Maui Punch/60 Chocolate Swirl/60 Orange Dream) = $928

*Family Pack and Experience Pack are available to promoters only

A word of warning – I don’t recommend buying from Amazon or ebay. You’ll find most of the vendors who sell it are trying to unload the old formula and who knows how old it is or how they’ve had it stored.

Just like fake designer purses, there are fake supplements and skin care products galore! And you won’t be eligible for money back guarantee unless you buy from the manufacturer.

Click Here to browse all of the Keto OS customer packages available on their website

Which Keto OS Package Should You Buy?

After my sister gave me a couple samples, I first bought the 60 Orange Dream Charged Pack which is 30 KAN servings (a scoop) and 30 OTG packs. I did the Smartship to get the $45 off.

The Smartship is totally worth it! It not only gives you a discount, but if you make any “one time” purchases in between you’ll get 17% off!

Since my husband also started drinking it with me and I like sharing, now I get the Family Pack. The Family Pack is 90 OTG servings and it has both flavors with a mix of everything (30 Orange Dream Charged, 30 Orange Dream Non-Charged, and 30 Chocolate Swirl Charged).

I also added a smart ship of two boxes of the  20 Bio Max Maui Punch. It’s very easy to change your smartship order if you change your mind. You just log in to your account and change your preferences with almost no lead time – which is awesome!

For those days that I want to drink two, I like drinking the charged in the morning and non-charged in the afternoon, and I like having the option of different flavors! It’s great to be able to change things up so you don’t get bored of the same flavor.

Good luck and I encourage you to try it! I have quickly become passionate about this product not only for the weight loss, but how great it’s helped both me and my sister to feel!

If You’re Still Unsure Which Keto OS Flavor to Buy

While ALL of the flavors contain ketones and will put you into ketosis to burn fat for weight loss, give you energy and focus, there are are some slight differences between the formulas.

If you’re unsure, maybe these tips can help you decide.

Orange Dream – may provide a slight edge on appetite suppression since it contains MCT Oils and will help to keep you feeling full. Many people start with the Orange. (Gluten free, does contain a tiny bit of dairy). Some people have reported feeling sick from the MCT oils, but this is your body adjusting and it should pass. Most people have no issues.

Chocolate Swirl – contains a prebiotic and has a lighter taste than the Orange (doesn’t contain MCT oils), great for a second serving in the afternoon (or pre-workout) or evening decaf, and very easy to drink. Vegan, Dairy and Gluten Free. Best for people with any stomach issues (or chocolate lovers;)

BioMax Maui Punch – The Cadillac of Keto! 😉 Great if you need an optimal energy boost and mental focus or as a pre-workout. It also tastes the absolute best in my opinion, very light and the easiest of all the flavors to drink. Vegan, Dairy and Gluten Free. I’ve had the best and quickest results while drinking the Maui and if it’s something you love the taste of, you’re going to be more apt to stick with it!

Like I said, you can’t go wrong with any of them. I really feel it’s best to have at least a couple of the flavors on hand so you can mix it up and also to see which one you like the best!

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 have lost 25 lbs on a ketogenic diet and stalled. Decided to try keto kreme and Max and it helped me break through my plateau. Really great flavors, the only drawback for me is the price.However, going to starbucks can be more expensive than a daily serving. I’m going to stick with it. only 4 stars instead of 5 because of the price.

I have MS and have been taking Keto OS for a month and a half. I thank God for my friend who introduced it to me. My inflamation is so much better. I have energy for first time in over 3 years. I have lost 22 pounds, pain is better, brain fog improving, migranes have been for most part gone. Had one migraine in 6 weeks. I feel like playing with my grandson and the 2 other little angels I watch. I feel like a new me.

Finally found a product that works!

Keto OS is amazing! I’ve been drinking the Bio Max in the morning and chocolate decaf in the afternoon and I’ve lost 15 lbs this month! 15! This is huge for me. I have two kids and nothing seemed to work to shed some of this baby weight. I have a ton of energy for my kids now and into the evening to get all my chores done and still feel good. And I’m sleeping like a damn baby. Love Keto, thank you thank you!

I bought this product initially for the energy. I’ve researched a lot on ketones for brain function. It’s helping me to have energy all day at work and deal with my three kids at night. I’m a happier mom because of it and the weight loss side effect is an added bonus. I have lost 15 lbs so far in a month. It really helps with appetite. I am also sleeping like a baby. I drink both the Chocolate charged in the morning and the punch decaf in the afternoon. People are noticing a change in me.

I was eating a low carb diet but my energy levels were low. Started drinking the Biomax fruit punch flavor and my energy levels are incredible and I’m staying in ketosis. I needed something to help me with energy mostly but it’s also suppressing my appetite which is a nice side effect. I’m a very happy customer.

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: 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

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.

    I thought you said that when your sister took it her stomach was upset for a couple days then she was fine and now you’re saying it took her about a week.

      Hey Carmen,
      I’m confused…did I say somewhere that it took my sister a week to keto adapt? 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

    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.

      Rachel Vrabel March 29, 2017 at 9:33 pm - Leave A Comment

      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

    Hi, thanks for your site and great info. I signed on to get this product, but the people are not knowledgeable and aren’t really motivated as you. I ordered 2 day shipment and paid extra, but no package. I’m Leary of sending others to this site now. How do I change referrers and get in touch with company. I’ll sign on under you since you are so supportive to your people.

    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 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.

    • Rachel Vrabel
      Rachel Vrabel March 3, 2017 at 9:30 pm - Leave A Comment

      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.

      Rachel Vrabel January 19, 2017 at 10:37 pm - Leave A Comment

      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

    • Rachel Vrabel
      Rachel Vrabel November 2, 2016 at 9:51 pm - Leave A Comment

      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

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 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.

      Rachel Vrabel July 3, 2016 at 3:45 pm - Leave A Comment

      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…

      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.

    Is there a special diet as well? Or just take Keto//os, I am sick of diet plans that don’t work and deprive me of food, hate feeling hungry.

      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.

    Started Keto Os!

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

      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

    I wanted to order this product, I’ve been doing research (which is how I found this review) and would like to try this but I have to have an invite/invite code (?) to do so. How do I get that if I found the information on my own?

      Julie, hmm I’ve never heard of that. When I initially purchased, I just ordered from my sister’s website. You can go directly to and order from me. Keto is sold as an “MLM” structure (like Beachbody) so you just have to know someone who promotes it, which I do. 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.

      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!

        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. 🙂

    I took a half a pack went into keto soon but checked later that day and was already out so how long does it keep you in ketois

    • Rachel Vrabel
      Rachel Vrabel February 28, 2016 at 4:35 pm - Leave A Comment

      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!

    Hi Rachel, I’m 36 years old and need to lose 15-20 lbs of post baby weight. I could relate to what you said about hormones. I only have time to exercise once maybe twice per week with two kids.Do you think Keto OS could work for me? How much would you recommend I buy? And will I have to change my diet? Thanks, Stacy

    • Rachel Vrabel
      Rachel Vrabel December 15, 2015 at 12:23 am - Leave A Comment

      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!

    do you drink it before or after a meal? If so, how much time before or after? Thank you

    • Rachel Vrabel
      Rachel Vrabel December 14, 2015 at 11:17 pm - Leave A Comment

      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! 🙂

    I just lost 8 lbs. in 14 days with the Paleo diet!! It’s simple and you’re never hungry!!

    • Rachel Vrabel
      Rachel Vrabel December 11, 2015 at 5:04 am - Leave A Comment

      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!
