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 that throws your body into a fat burning state of ketosis within 30 minutes.

I’m going to warn you, this is a very long and thorough review, but I think it will answer all the questions you may have on Keto OS and you’re going to learn a few new things.

What is ketosis? Ketosis is when your body is burning ketones for energy instead of glucose.

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 is all the craze right now, 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 Keto OS?

The reason I chose to review Keto OS is because my sister is drinking it, and now I am too! She 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!

I haven’t seen her this focused and feeling good about herself in years.

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.

It’s the first natural consumer product to provide elevated blood ketone levels to the body.

Keto OS contains a patented and proprietary engineered ingredients formula of ketone mineral salts and MCT oils (extracted from coconuts) for optimal protein synthesis that equals high energy fuel, and the recommended dose is to drink it once or twice per day.

Ketones produce 38% more energy than glucose and is an ideal choice to fuel the body with more power by burning fat.

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

Ketosis Explained

When we were hunter-gatherers, we would have an energy surge when we were low on food (fasting) by way of ketones flooding the body.

We would go into ketosis and burn fat instead of muscle until we found our next meal. This is the body’s physiological method of survival.

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 takes 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 without having to restrict your 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?

Would following a clean eating diet boost your results? Absolutely, that’s a no-brainer, but you don’t have to change your diet for this product to provide results.

The folks at Pruvit recommend a ketogenic diet for optimal results, but you certainly don’t have to follow this diet for Keto OS to put you into ketosis and provide results. That’s the beauty of it!

If you’re following a ketogenic diet already and have trouble staying in ketosis – drinking Keto OS can keep you in ketosis for 24 hours.

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!

I highly recommend at least trying to clean up your diet a bit and exercise if you want to get better results from drinking Keto.

The ketogenic diet is in fact the diet recommended for many health ailments (such as my sister’s epilepsy) since it’s an anti-inflammatory diet.

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. This is the flavor I first started with!

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.

They offer both On-the-Go (OTG) individual envelopes or you can also buy the KAN which is a big container with a scoop. You simply mix one envelope with 12-16 oz of water, shake, and drink!

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

The recommendation (and what I did) is to start by drinking only one-half of an envelope per day to allow your body to adjust to it for about 4 days.  Now I’m drinking one full envelope of the Charged in the morning mixed with water.

It also 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.

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.

So if you’re a chocolate lover, you’re going to love how this tastes!

It tastes like a light chocolate milk, and if you add some ice to it, it tastes like a chocolate milkshake – so good!

Chocolate Swirl only comes in a “charged” version with caffeine.

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 – purest and most bioavailable ketone delivery

**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 also a bit lighter than the other flavors which I like, it’s very easy to drink.

As I sit here sipping on the Bio Max Maui Punch “Charged” version, I’ve only finished about half and I am one big ball of energy! I have an Orange Theory Fitness class scheduled at 4:30 and I’m raring to go!

The Bio Max version is the latest and greatest from Keto OS. It has the most pure, most bio-available form of ketones.

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

Bio Max comes in both Charged and Non-Charged. My advice is to drink charged in the morning and non-charged in the afternoon.

**UPDATE 1/18/17** 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 almost have to remind myself to eat (in fact I do), since it suppresses my appetite so much.

I’m going to admit, I do like it better than the Orange Dream, but I still love the creamscicle flavor of the Orange. I have a friend who actually mixes these two flavors together so I definitely want to try that.

I’ll continue to update on my progress! I still have some weight to lose and some muscle I want to add! 😉

Keto Kreme – Healthy Fat Source for Your Coffee

Keto Kreme review

Keto Kreme mixed with hazelnut coffee

Just a quick mention, 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.

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.

I add it to my hazelnut coffee sometimes and it’s delicious! This is a supplement that goes hand in hand with a ketogenic lifestyle.

Recommended dose is once per day, in additional to drinking Keto OS up to twice per day.

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.

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 would.

But if you’re a regular coffee drinker like me, then you probably won’t have any issues.

Some people report a slight upset tummy when they are adjusting to it, and this is the reason to start with half a pack for at least a few days.

I did not experience this but my sister did the first couple of days she drank the Orange Dream it but it didn’t last. This is your body getting used to the MCT oils.

Maui Punch does not contain MCT oils, just pure ketones. And the Chocolate Swirl contains a prebiotic if you have gastro issues.

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.

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.

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! 😉

After the first week, I shed 5 lbs EASILY. 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.

I would go running/walking (4-5 miles 3x per week), weight train, play beach volleyball, nothing worked. When you hit a plateau where the scale doesn’t budge, it can be very depressing.

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.

Maybe it was a little premature writing this review, because I haven’t lost that much weight, but often 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, I can definitely see how a product like this would make it really easy. Not only because Keto OS is engineered to put you into instant ketosis, but it’s going to make you eat less, have more energy, and feel more focused.

**UPDATE** My Keto OS Before and After Photos

keto os before and after photo

Keto OS before and after photo. 10 pounds lost!

Ok so I promised to do this….I’m putting myself out there so you can see for yourself what Keto-OS can do.

My before pictures were taken four weeks before my after photos. So in 4 weeks, I’ve lost about 10 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 also feels slimmer and less puffy.

I would be willing to bet I’ve lost 10 lbs of fat but added 5 lbs of muscle. So I can’t go by the scale anymore, I’m going by how my clothes fit.

This is progress! I know I’m already small framed, but the last 5-10 lbs is always the hardest. I would actually like to add more muscle, but for now 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.

My Ketogenic Goal for 2017!

What is different about keto os bio max

Bio Max Maui Punch, I start my day with it!

My goal for 2017 is to eat “more” of a ketogenic diet. I’m not going crazy with it, I’m just going to try to lower my carbs and eat more healthy fats like salmon, avocado, nuts, cook in coconut oil and commit to drinking Keto OS daily.

Am I going to cheat and eat carbs? Of course! There’s no way I could personally follow a strict ketogenic diet ALL the time, I like good carbs too much (and occasional pizza!).

But this is where the Keto OS helps – even if I cheat I’m going to stay in ketosis and continue to burn fat for fuel.

I also joined Orange Theory Fitness and at 44 years old, I plan on getting in the best shape of my life!

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!

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.

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! 🙂

As of right now, 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 preventative health.

The Smartship option does provide 17% savings – this is where they’ll automatically send it to you each month (but this is just an option and you can cancel anytime).

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. This is someone’s leftover product and there are a lot of fakes out there. Just like fake designer purses, there are fake supplements and skin care products galore! And you won’t be eligible for money back guarantee.

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 30 OTG Pack in Orange Dream Charged and did well with that for a few months. I did the Smartship and saved $16 off the $160 price so it came out to $144 per month.

Since my husband also started drinking it with me, 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).

Now that I’m love with the Maui Punch flavor, I changed my order online to include the smart ship of the Bio Max so I can save on it since it’s a bit more expensive than the other flavors.

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!

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!

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.

I drink a combo of the Orange and the new Bio Max. If you like to lift weights, having a serving before the gym can really help you lift heavier, stay sharper and eases inflammation, I don’t get as sore as I used to. This stuff has helped me lose about 5% body fat in a few months. Bio Max is more expensive so I also get the Orange flavor to keep the price down, I like both.

I am impressed so far. I mostly lift weights and wanted to get “shredded” or lean out. Keto is giving me energy to push through the burn and suppress my late night munchies, which is probably what was keeping me from meeting my goals. For only being on it two weeks, I’m already seeing a difference. I feel leaner and less bloated for sure. I also seem to not get as sore from my workouts. Great stuff so far so good.

I started drinking Keto a couple of weeks ago, bought the 30 pack to try for a month. My energy is through the roof and I’ve lost 6 lbs. It gives me steady energy throughout the day and I don’t crash like I used to. Good stuff. I know this review was from a women’s point of view, but it works well for guys just the same. Do some research on this product and you’ll see it does a lot more than weight loss.

I work in an office of overweight people. I’ve lost 15 lbs this month drinking keto twice a day. Charged in the morning and decaf in the afternoon. People are asking me my secret so now we have a keto os weight loss group at work. Some of us have also been walking for 30 minutes during lunch. My joints also don’t hurt as much anymore and my blood pressure is lower. I’m still new to keto but it’s exciting to be the start of something great and we are all eager to get our health back!

I lost 2.5 lbs my first day…

I started drinking Keto yesterday and wanted to share my experience. I drank half a pack of the charged at 7:30 am. I wasn’t hungry all day but forced myself to have small snacks and a healthy, low carb dinner. I don’t know if I was bloated before but I woke up this morning and had lost 2.5 lbs! I had a little trouble going to sleep last night probably because I didn’t exercise to burn off any of the caffeine affect. I am going to drink half another couple of days before drinking a whole one. I’m loving this stuff so far! I am over the moon how it helps to kill my appetite and late night snacking!

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: 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: 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: Is this safe for headache/migraine sufferers ? & Can you take this for life ? -Libby

A: Hi Libby, I don't see why it wouldn't be safe for migraine sufferers...but I'm not a Dr. so I can't be sure. Keto OS has many health benefits other than weight loss. You can take it for life, lots of people make their lifestyle Keto friendly and use Keto OS as a supplement for a ketogenic lifestyle. Check out all the Q&A at the bottom of the Keto OS Research page on their website, there is a ton of good info here regarding how Keto OS affects and/or helps certain health conditions. Let me know if you have any more questions. Thanks, Rachel

Q: Can you clarify something for me if possibe. I wanted to find out if the Keto//os chocolate swirl in fact has chocolate in it?? I have been told Natural Chocolate Flavour & NO cocoa but not clearly stated what Natural Chocolate Flavour actually is? & also is it chocolate?? I am allergic to chocolate due to migraines so don't want to get it if in fact it is chocolate. Can you clarify please :) -Libby

A: Hi Libby, thanks for your question. The chocolate swirl doesn't contain chocolate, just natural flavoring. If you visit the chocolate swirl page, and then up towards the top click on "Use and Ingredients" then it will show you a picture of the label. You should be fine :) 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

  2. Lisa January 16, 2017 at 10:00 am - Leave A Comment

    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?

      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

    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.

      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

    what happens if you stop taking it?

      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!

      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. 😥 Have the terrible over 50 menopausal weight gain and totally do not feel good about myself or like the way I look anymore…. Ugh…. 😣

      Hi Jody, I’m sorry but I can’t find it either. I was actually searching for it the other day and it doesn’t appear that they offer it any more. 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

      Hi Juliet, Keto OS won’t stall your metabolism at all. I took it and lost the weight I wanted, and then stopped. I didn’t gain any weight back until I started REALLY slacking on my diet again. 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

  9. Deborah August 30, 2016 at 1:27 pm - Leave A Comment

    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.

    • Rachel Vrabel
      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…

    • 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.

      Rachel Vrabel April 16, 2016 at 12:57 am - Leave A Comment

      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?

    • 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

      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.

    • 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. 🙂

      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!

    • Rachel Vrabel
      Rachel Vrabel January 15, 2016 at 12:39 am - Leave A Comment

      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!

      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!
