Keto OS Review

2.8 out of 10

People Who Viewed Keto OS Diet Also Viewed PS1000 Plan.

KETO-OS product is produced by a company called Pruvit Ventures LLC and is located in Texas, USA.

Ketosis is a condition that raises levels of ketones in the body and provides abnormal fat metabolism. Ketosis is a body condition when instead of glucose body fat is used for fuel. Body goes into ketosis when ketone production starts.*

The science, explained by Pruvit, about the KETO-OS is that if you add more ketones your body might go into ketosis without extreme dieting, therefore creating a body that is more alert, with high-energy use and faster metabolic rate. The company promises weight loss (even though they say “it is not a weight loss supplement).*

It is not a cheap product and comes at a price of up to $ 5.66 per serving. The company claims that you will be able to notice changes in your body within 59 minutes. This is a very hefty and unrealistic claim.

Do Dieters Lose Weight On The Keto OS Diet?

We were able to find some real customer testimonials.

“This product was very hard on my stomach and digestive system, and I don’t have a sensitive digestive system. Since it was hard on my system I was unable to take it long enough to evaluate it. I tried 2 different times for a few days, building up to a full does as instructed. Gave up both times.” Susan*

Amelia* said, “This product does NOT put you into ketosis faster. It may show up on keto strips as being in ketosis but those are NOT relialble (you should use a ketone meter if you’d like to track). This company steals before and after pictures from Keto/LCHF groups on Facebook and reddit to make it seem they are losing with this and their keto diet, but I know OVER 20 people who said the company stole their pictures.” She goes onto warn the potential customer reading this review, and not to buy the scam product. Keto is really all about keeping your carbs under 30 grams a day and not taking any supplements or shakes in the process.

“This stuff is loaded with caffeine. So, if you like the sensation of having about 120 cups of coffee smacked into your system in one jolt, this is the stuff for you. As for the other benefits claimed for it, I’m not sure the price of the NoDoze jitters is really worth it for me to stick with the product and find out. (And I like coffee and metabolize caffeine well.)” Tim Roessler*

Is The Keto OS Diet Easy To Follow?

Recommended dosage is 1 – 2 servings of KETO-OS per day; 1 Serving in the morning, 1 in the afternoon or before a workout. For people with supplement sensitivities company recommend taking ½ the serving in the morning and ½ serving in the afternoon.*

Conclusion

When it sounds too good to be true it most of the time is. The company has done a great job in creating a buzz in just a few short months on the market but more and more customers that have actually been very excited to find this new unbelievable “science based” product that will help them achieve their long longed for goals, started posting reviews of the product not living up to their expectations. Unfortunately, there is no magic pill that has been invented (maybe there is but we simply have not seen it on the market) that would give you so many benefits (we have seen as crazy of claims as of it helping to cure cancer). When looking to improve your energy, lose weight and feel good we recommend choosing a plan that will have a few key elements: healthy eating plan, customer support groups and health coaches who can help with any questions or struggles you might have.

  • Born with a Sense of Humor

    I was researching this product as I seem to do better on low carb (I’m a carb & sugar addict). I prefer to go running while caffeinated, so that level doesn’t bother me. I’m reading these comments and just rolling my eyes.
    People – Mr. Ferguson is simply stating that, if you start using a product, in conjunction with cutting back on simple carbs as instructed to by said product, you will lose weight quickly in the beginning. Most of it in this first stage is simply water weight. If this is the first time doing a low (<30g) carb, it's pretty exciting! Almost a miracle!
    I can usually cut down on carbs and go into ketosis pretty quickly, and I usually do this once in awhile to kick start dropping water weight.
    As for the people who are focusing on the whole "120 cups of coffee" comment… really? These are the ones who need a "sarcasm font" to help them get a joke.
    The name calling and arguing is just hilarious. I commend Turd for actually trying the product and am excited to hear his final thoughts.
    Funny, the one person that everyone is attacking is the one person who might sway my decision on trying or not trying this product.
    Please let us (me) know how it goes!

    What a biased hit piece! Geesh, look at the the feedbacks he pulled. A real journalist soul have given feedback from both sides. Does it out you in Ketosis? Yes! I have the ketone test strips to prove it, both urine and blood. Blood test is the most accurate. I am a type 2 diabetic. My bg levels have stabilized to 95-100 fasting within 2 weeks. No spikes or sudden drops. I have those charts from my meter app that can prove it as well. (All downloaded straight from my meter). I was already on a low carb diet due to my diabetes so I had no stomach upset. People who are not on a low carb to begin with MUST wade in slow and build up to a full packet or that will have stomach upset.

    As far as caffeine and 120 cups of coffee: Do your research! Pruvit offers mom caffeine as well. The only difference I can feel is my energy increases at about the 30 minute mark with the CF.

    BTW it is far loss not weight loss. You measure by inches not pounds as muscle which Keto OS preserves weighs more than fat. A good promoter will tell their clients to measure themselves weekly to see those results.

  • Samantha Carter

    About 6 weeks ago I said “YES” to BETTER!!!

    I ordered my Keto/OS Orange Dream and Chocolate Swirl !!! For 5 weeks I have been drinking my Ketones everyday!! For the most part it’s only been once a day! There are some days I have drank my Ketones twice a day. This drink has helped me in so many ways! I have slept better then I have in many years! I wake up feeling refreshed and ready to start my day! I have more natural energy to play with my 2 wonderful kids, and get everything I need to in my day done. I have better focus and can finish something I started. I have control over my appetite for the first time ever! I am not drinking soda, or eating sugar, I eat smaller portions and I am not craving nasty fast foods!

  • Jane

    Have lost weight while using this product but I’m also following an alkaline diet so not really certain which is being more effective. The problem I have is getting the product shipped. First time got an email with a tracking number but when I checked it UPS read ‘voided.’ Contacting the company was a long drawn out process even though my credit card had been charged! After two weeks finally got the order but no explanation. Ordered a second time and still waiting two weeks later…even though company updates says it’s in Canada! No response from support! I think it should be illegal to charge a credit card before shipping. Wish I could find a consumer advocacy group to register a complaint against Pruvit Canada!

  • Mike Anthony

    There are plenty of actual doctors that are pro and con towards exogenous ketones.
    While it’s true that Nutritional Ketosis is the ‘real way’ to burn endogenous fat, using products like Keto OS give the consumer a leg up on getting started.
    I’ve done that before- and had great success- but it was terribly difficult, and nearly impossible to sustain. Cooking separate meals for myself and 4 children wasn’t sustainable, so I fell off of it. This time around, the supplement makes switching to a LCHF diet absolutely effortless.
    Keto OS has appetite suppressant effects, along with the rest of the cognitive enhancements; that alone will cause a drop in caloric intake…which naturally leads to weight loss. What few people are saying about this product, is that the cognitive effects elevate your mood so much, clear your brain so well, making dietary choices is actually a joy, now- like the saying goes: when you feel good, you DO good.
    The combination of effects from using this product justify the pricing. I’ve used three different kinds, and this is by far the only one that actually does what it claims to do.
    In the interests of total transparency, I *do* provide it to people, reluctantly; I’m not a fan of mlm businesses, but I am a sworn and sold fan of Keto OS. I’ve dropped 26 pounds in 8 weeks, using it and loosely following a keto diet. Due to a bad back, I needed some help dropping weight without exercise being a usable option- and this product has helped significantly to get my body to the point where exercising, as an option, is now back on the table.
    The science is there.
    Thousands of testimonials are there.
    No one has to believe; we all have the right to an opinion…
    …but walk the walk before you talk the talk. https://uploads.disquscdn.com/images/b5570b3e58082be0291037412e236940023058f7c067adbbab436b4bdf0377ee.jpg

  • Joshua James

    Well I’ve been doing this for about two months … I started at 186 pounds and 12.5% body fat… ice since dropped to 168 and less than 8% body fat… Yes it does jump you into ketosis …1 serving has kept me ijn ketosis for 5 days so I would say the supplement is washed out by then … Not a reliable website or research done by this site …. anyone with any real questions or concerns are welcome to cokntact me directly … “everything on the internet is true” – Abraham Lincoln

    • Turd Ferguson

      How do you know you’re in a metabolic state of ketosis? I assume you have urine test strips? Don’t you understand that if you are taking this supplement that has ketones in it, then when you urinate you are also peeing out the ketones you are taking….on to the test strips? How hard is this for people to understand? Really hard, apparently.

      • Grim

        Turd gets his product from his Mom? I assume when she brings it down to her basement where he lives. Along with meatloaf.

        • Turd Ferguson

          No, but I do bring my meatloaf down on your mother. If you know what I mean.

      • Winter Buklad

        I did a blood ketone test approximately 1 hour after drinking and my ketone level went from 0 to 2.1. So yes, it does work.

        • Turd Ferguson

          Winter, anything you ingest gets in your bloodstream. That’s why alcohol makes your feel warm and fuzzy. I never said you wouldn’t get ketones in your blood by ingesting them. I suggested it wouldn’t put you into a medical state of ketosis in which your liver is naturally producing ketones any faster or more efficiently and it hasn’t been proven to. You really need to google and find out the differences between exogenous ketones & endogenous ketones and how they both effect the body. I’m not even saying this supplement isn’t beneficial or healthy. I’m taking it now. It seems to give me good energy. However, it won’t keep you in ketosis with a carb-heavy diet and it won’t put you into ketosis in 45 minutes. It takes time for your body to switch it’s fuel source from carbs to fats(ketosis).

          You saying you had ketones in your blood after you took a supplement with ketones in it isn’t brain science. How is this so hard to grasp?

  • Lori Fields

    I started the Keto OS Thursday April 27th 2017, I HAVE NOT changed anything about my diet and I’ve lost.7lbs already! I figured, anyone can lose weight cutting carbs and sugar out of their diet. So I decided to see if it actually works without changing any part of my diet, and it DOES! So for you non believers…it does work.

    • Lori Fields

      So 7lbs in 4 days

  • divingbelle

    I have Myalgic Encephalomyelitis and my #1 complaint is constant fatigue, I’m on day 3, and I have more energy than I’ve had in years…this is my personal journey, not a medical claim…I can also choose to take caffeinated or uncaffeinated versions. I’ve been taking 1/2 packet in the am and one at lunch, to trouble with my digestive tract and I get bouts of IBS, so I’m pleased my body can tolerate it. Like anything people inject, some can take it and others can’t.

  • Denise

    I disagree with this. I have lost 4 pounds in 10 days, feel great, sleep well and I’m not hungry. I don’t feel jolted drinking orange caffeinated version at all. I love this product and have seen amazing results in my friends.

    • Turd Ferguson

      Okay 4 pounds in 10 days becuase you’re eating a keto diet without carbs so you have lost 4 pounds of bloat and water weight. Has nothing to do with these pills that fill your pee with ketones and makes it look like it “jolts you into ketosis.” I always lose 4-5 pounds my first week in keto without these supplements. Stop wasting your money.

      • Turd Ferguson

        jesus christ

      • Rachel Vrabel

        It’s not a pill either dumbass. If you’re reading this, Turd face Ferguson has no idea what he’s talking about. Refers to it as a “shake” in one comment, a “pill” in another. Gimme a break dude. Hit me up and I’ll send you some of mine to try!

        • Turd Ferguson

          Pill, smoothie, fucking inject the shit into you. Doesn’t matter the vehicle. It’s a god damn placebo and hasn’t shown to actually put your body into a state of ketosis any faster. You just piss out the ketones you drank with the shake also when you text via urine strip it shows ketones. Doesn’t mean your body is in ketosis and producing them naturally ya doofus.

          • Rachel Vrabel

            Where on earth are you getting such misinformed information? There’s a shit ton of research behind this product. Yea, I lost 13 lbs from a placebo…my mom lost 15….my brother lost 20….my cousin lost 15 – all within 4-6 weeks. Everyone feels energized and is experiencing ketosis. This ain’t no placebo effect buddy, exogenous ketones are real. Your doing your mom a disservice. You should order some for her and see for yourself. Pruvit offers a 60 day money back guarantee…. I’m not into arguing online. But you have got to have some hidden agenda carrying on like you have been on this forum. Good luck to you.

          • Turd Ferguson

            No, I have yet to find one credible study on this specific product. ONly anecdotal evidence can be found. But, I’ve taken it upon myself to order two months worth. I’m going to do keto exactly like I did 6 month ago. Same diet, same workout plan, etc and I’m going to supplement daily with this. I will tell you in a couple weeks if my results are better than they were the last time I did keto without this supplement. Im guess it will be the same. I think this is simply a very expensive energy supplement. But, we will see.

          • Jane

            Hey, good luck getting your product in time so that you can provide an update in ‘a couple of weeks!’ Perhaps delivery is better in the States?

          • Turd Ferguson

            I already have the product. I have OS and the Kreme coffee creamer. My mother bought them and I told her I’d try them out for her as the guinea pig and order her more. I’m a 5 days into taking it daily. I got into keto in 3 days, not 45 minutes. To me, so far, the supplement is very good for sustained energy, but so far I think it’s hardly worth spending $100 per month on it. Will update in a couple more weeks.

  • Trixie

    Sorry, but I will have to disagree with you. This is working great for me so far. Have not changed my diet at all and it has cleared up my dermatitis in just 2 weeks. Also lost one and a half kilos in that time. I definitely have more energy and looking forward to seeing what the next 4 weeks brings. Just wondering if the person who wrote the article bothered to try it out for themselves or just wanted to write something biased on which they had no personal knowledge on?

    • Turd Ferguson

      So you haven’t changed your diet at all or your lifestyle and lost 5 pounds just by taking this? Doubt it

      • Rachel Vrabel

        Haha… Trixie is experiencing the magic of exogenous, therapeutic ketones!

        • Trixie

          Maybe, all I know is that it works for me.

          • Rachel Vrabel

            I was actually directing that to Turd being sarcastic. Exogenous ketones ie Keto OS is amazing!

          • Trixie

            Lol just realized that sorry. Note to self, do not get on social media when you have a migraine! What I failed to mention to the troll was my diet was actually worse as my brother was staying with me at the time and the amount of sugary processed food he brought into the house was more than I usually have..and if it’s in my cupboard you know I’m gonna eat it lol.

      • Trixie

        Actually yes, and I really don’t care that you doubt it. It’s just how it is.

        • Turd Ferguson

          If you changed your lifestyle then maybe those other changes attributed to your improvements and not this pill. Lol

    • Trevor Axford

      just curious what is your diet? if you are taking a lot of carbs then it will be impossible for your body to go into ketosis as you are providing a fuel source that your body will automatically use first instead of the stored fat. Ketosis requires a low carb high fat diet. Your weight loss may just be water or if your hunger is being suppressed you may be taking in less calories. I too am taking Keto OS and it does give you energy and make you feel better.

  • John Genua

    Who’s paying you to trash this product? 4 months 1-2 times per day along with the LC-HF diet and down 28 lbs. There’s a non-caffeinated version if you’re caffeine sensitive.

    • Trixie

      And it’s about one cup of coffee not 120 like they have written.

    • Turd Ferguson

      Dumb fuckk. People have been losing tons of weight on keto low carb high fats for decades. Ever wonder if you would have lost same amount of weight without spending money on this fake shake?

      • Mike Anthony

        Please see my latest post on here.

        • John Genua

          Thank you- Turd Ferguson (real original call-back to a 2000 SNL skit) seems to be very angry….I’m not a MLM fan either, this stuff was not pushed on me, and it works. I do intend on attempting to holiday it eventually and watch the results with just the diet alone

      • John Genua

        “Ever wonder”- no I lack common sense and logic- instead I angrily type on a review site all day.

  • Rachel Vrabel

    Keto has worked great for me twice. The first time I lost 11 lbs in three weeks drinking the orange. A year later I’d gained some weight back and have been drinking the Bio max Maui punch. I lost 8 lbs in two weeks and I love the energy. Been back to drinking it six weeks now and my body continues to change. Fat is being reduced and my workouts are great! Love the energy and it does not give me the jitters at all. It’s expensive but the best supplement I’ve ever been on.

    • Turd Ferguson

      Why not just take much more affordable energy supplements? They would do the same thing. This supplement doesn’t get you in ketosis faster. It’s fooling you.

      • Rachel Vrabel

        You’re misinformed. Prüvit brought exogenous ketones to the market place and there are no other products that even compare. Unless you want ketones made out of China by imitator products. It’s a bit pricey, agreed, but worth it. More affordable “energy” products are not ketones. If you like shitty diet pill supplements that give you the jitters and don’t have any longevity then you can buy something cheaper. Keto OS puts you into ketosis within 30 minutes and you’ll stay there all day. I do not follow a strict ketogenic diet by any means and stay in ketosis. Nutritional ketosis is difficult to get into unless you are perfect with your macros, been there done that. Even some keto dieters have a hard time getting into nutritional ketosis or staying there. Have you even tried this product? Why are you bashing it when so many people have had life changing experiences on it? Myself included. If you’re doing keto diet and having great results, good for you. Some people need the help and like the energy and focus it brings. Peace.

        • Turd Ferguson

          Not being in “nutritional ketosis” means your body is not naturally producing ketones. You’re just pissing out the ones you’re drinking and thinking you’re in ketosis.

      • Trevor Axford

        I don’t think the product is truly getting you into ketosis faster but it is helping you to eventually get there by having quicker weight loss results (whether it is just fluid or not it is still a positive result) which keep people motivated and without all the side effects that come along with changing your bodies fuel source like headaches and mood swings
