Ketone Drinks: Types, Benefits, Risk & Safety, Drawbacks


Our bodies produce ketones when we restrict carbohydrates — for instance, following a keto diet. We can also take a ketones drink (popularly called exogenous ketones) to support nutritional ketosis and experience its benefits.

Before deciding to supplement, it’s helpful to know the types of ketones that are available, how they help in certain areas of your health and wellness, their safety, and the best ketone supplements on the market.

What are Ketone Drinks?

Ketone drinks or exogenous ketones are a supplement form of ketones that your body naturally creates — in other words, endogenous ketones — by limiting carbs or entering a fasted state.

Your liver produces three types of ketone bodies, namely, acetoacetate (AcAc), beta-hydroxybutyrate (BHB), and acetone (Ace). When you’re in a state of ketosis, you use BHB as your main energy source instead of carbohydrates.

It’s important to note that your body is constantly producing ketones that create 22 adenosine triphosphate (ATP), the energy-carrying molecule, even when you’re eating carbs. However, this increases in ketosis (*).

When it comes to exogenous ketone supplements, you may have noticed BHB as the ketone that’s found in the drink. This is because BHB is the main energy source your body runs on.

Research suggests that 100 grams of BHB produces 10,500 grams of ATP, which is higher than glucose (*). Taking a BHB ketone drink can support a healthy keto lifestyle, including your workouts, mental performance, and energy levels. This is why BHB ketones are considered a “superfuel” and it’s what ketone supplements are based on.

Types of Ketone Drinks

When looking for a ketone supplement, stores will offer two types of drinks. These are ketone esters and ketone salts. Here’s how they differ:

Ketone Esters

Ketone esters are ketones that are bound to an ester. While they’re more efficient in raising blood ketone levels, they’re not as available as ketone salts (*). Furthermore, ketone esters don’t taste as good as ketone salts — although some people don’t like the taste of ketone salts to start with.

Another potential disadvantage is that their long-term safety has not been fully established. Plus, they haven’t been well-tested in humans (*).

Ketone Salts

Ketone salts, as the term implies, are bound to a mineral salt, such as sodium (Na), potassium (K), magnesium (Mg), and Calcium (Ca). They’re widely available and they also come in capsules. Compared to ketone esters, ketone salts taste better, which makes them appealing for most people. However, those who personally dislike the taste of ketones and want something more convenient can get BHB capsules instead of drinks.

Important: Note that raspberry ketones are not BHB ketone drinks. Raspberry ketones are made from raspberries and they do not increase your ketone levels.

Scientific Facts and Research About Ketone Drinks

For those who are interested in ketone drinks, studies have been done on ketone body supplements in various aspects, such as sports performance, brain health, and supporting nutritional ketosis.

For example, a review article in Frontiers showed that administering an exogenous ketone supplement can meet a brain’s energy needs during an energy crisis. Thus, it may help with brain conditions, including seizures, Alzheimer’s disease, and traumatic brain injury (*).

While exogenous ketones are generally recognized as safe by the FDA, keep in mind that the ingredients in a ketone drink can vary from one brand to another (*).

Researching the right brand, being aware of possible side effects, and consulting your healthcare provider if you have a medical condition will help. We’ll be discussing more about the drawbacks of ketone drinks later in this article.

Benefits of Ketone Drinks

What can you use ketone drinks for? They’ve been shown to help with achieving a state of ketosis and other positive effects of being on a keto diet, such as appetite suppression, improved workouts, and mental performance.

ketone drinks benefits

1. Ketone levels increase

Exogenous ketones directly impact ketosis by increasing your body’s beta-hydroxybutyrate (BHB) ketone levels.

One important reason people decide to drink ketones when they’re just starting a keto diet is to reduce keto flu symptoms, such as headaches, brain fog, fatigue, and body aches (*). Having a ketone drink allows them to transition into ketosis sooner and more comfortably.

According to a 2018 paper, exogenous ketone supplements are “a safe and effective way to increase ketone body concentrations.” In addition, it mentions that while ketone supplements increase BHB levels in the blood, they do not cause your liver to produce more ketones (*).

2. Reduced food cravings

Since exogenous ketone drinks mimic ketosis, they suppress your appetite, which helps you lose weight in the process.

It’s normal for you to experience strong carbohydrate cravings when you’re transitioning from a high-carb to a low-carb diet and this is when a ketone drink can be beneficial. But of course, cravings still happen when you’re already an experienced keto dieter, especially when you’re under a lot of stress and you lack sleep.

In one study, scientists explored how ketone ester drinks affected subjects’ appetite and hunger levels. They found that 60 minutes after consuming the ketone ester drink, their blood ketones increased from 0.2 to 3.3 mM. Furthermore, the subjects reported reduced hunger and lacked the desire to eat 1.5 hours after (*).

Reducing hunger and appetite helps with people who want to lose weight. It can be one of the ways they can control their calorie intake (*).

3. Better workouts

Whether you’re an athlete or exercise frequently on keto, an exogenous ketone supplement can provide you with additional support so you can push through a workout. This includes endurance exercises and those involving sprints and quick movements (*).

As an added benefit, it may even help improve your recovery post-workout. According to a  review paper, exogenous ketones can reduce the sensation of fatigue and facilitate the replenishment of muscle glycogen (* , *).

4. Mental performance and productivity

Your brain keeps foreign substances out through the blood-brain barrier.

Glucose cannot cross the blood-brain barrier by itself, so it relies on glucose transporter 1 (GLUT1). When you eat carbs, you experience swings in the energy that is available to cross the blood-brain barrier using GLUT1. And these swings that lead to high energy levels, followed by brain fog.

Ketones are different in that they’re moved about by a different type of transporter — monocarboxylic acid transporters (MCT1 and MCT2). These transporters become more efficient when more ketones are available (*).

What this means: You can have a constant supply of energy to your brain by consuming ketones, which can help with reducing brain fog and improving your focus at work.

5. Gets you back into ketosis faster

Some people choose to eat more carbs on certain occasions or during the weekend. This can kick them out of ketosis. For those who’ve experienced falling off the keto wagon, they know that it may take a while before they can get back in.

Exogenous ketones can help you transition into ketosis again. It means that you take them while you’re implementing strategies like lowering your carb intake, exercising, and fasting intermittently to deplete your stored glycogen.

Are Ketone Drinks Safe?

Ketone drinks are generally safe, although you need to take them strategically. Use them in addition to a properly formulated and healthy ketogenic diet instead of a standalone supplement. Concerns regarding ketone beverages usually relate to taste issues, diarrhea (which is common), electrolyte imbalances, and ketoacidosis, which are rare.

Potential Drawbacks of Ketone Drinks

Like other supplements, ketone drinks are not perfect and may cause side effects depending on the individual.

ketone drinks drawbacks

Digestive issues

Studies suggest that higher and repeated doses of ketone salts and ketone esters can lead to gastrointestinal intolerance. Symptoms may include diarrhea and nausea (* , *).

If you’re interested in a ketone drink, it might be best to start with the lowest possible dose and then notice how you feel.

Electrolyte imbalance

Since ketone salts contain the minerals sodium, potassium, magnesium, and calcium — consuming large amounts may put you at risk for an electrolyte imbalance. Although these minerals are essential, taking too much leads to problems.

Abnormal concentrations produce symptoms, such as muscle cramps, muscle weakness, difficulty sleeping, and restlessness (*).

May induce ketoacidosis

While this is rare, do keep in mind that combining a ketogenic diet, prolonged fasting, and taking exogenous ketones increases the likelihood of ketoacidosis (*). Ketoacidosis is commonly related to diabetes; however, it can still happen due to starvation.

Frequently Asked Questions

Discover answers to common questions on ketone drinks:

Are ketone drinks good for you?

Consuming ketone drinks can be helpful for kickstarting your goals on the keto diet. This means that they allow ketosis to happen sooner, support weight loss (through appetite suppression), and help boost energy for your workouts.

When and how often should I drink ketones?

People usually take a ketones drink 30 minutes to 1 hour before a workout on an empty stomach. As for the frequency, brands will often recommend up to three servings a day. Follow the instructions, adjust according to your needs, and speak to your doctor if possible.

Do ketone drinks work for weight loss?

Exogenous ketones cause weight loss indirectly by lowering your appetite. The same thing happens when you’re in nutritional ketosis. This explains why people feel less hungry on keto than they did before doing the keto diet.

The Bottom Line

Ketone drinks are here for a good reason — they serve as a tool to boost the effects of the keto diet. In particular, they help you transition or get back into ketosis, improve your physical performance, reduce your cravings for weight loss, and enhance mental clarity.

Exogenous ketones are available in ketone esters and salts, although ketone salts are more popular and palatable too. Digestive issues, such as diarrhea and nausea, happen to some people who take large doses of ketone drinks, so keep that in mind.

Overall, they support your low-carb lifestyle and health goals. Use them to achieve better results, but don’t make them a quick fix. As supplements, ketone drinks are intended to help and not replace your diet.

135 thoughts on “Ketone Drinks: Types, Benefits, Risk & Safety, Drawbacks

  1. How long does your body stay in ketosis after using exogenous ketones? I have read that you get into ketosis within an hour after consuming, but cannot find how long you stay in ketosis?

      1. Try 70% fats 15%protein 15%carbs. I consume 3Tbs. olive oil, avocado, or coconut oil per meal. Also use ghee to fry eggs in. Females use 2Tbs of the above oil. If your over 50 yrs. Dr. Don Colbert recommends a Lipase supplement to help break down fats. He has a book titled The Keto Zone I highly recommend it if you are doing a Keto Diet. I started out weighting 256lbs. lost 22lbs and 17inches in 4weeks. I eat 6oz. protein, 20grams carbs and 70%fats from above fats.

      2. coffee doesnt effective ketosis. its actually encouraged. Add coconut oil or even tablespoon of butter to coffee to increase mental clarity and focus in morning (old military trick)

      3. Hi I need a little bit of help. I’m not sure how much of the shake I can drink and how much food I can eat. It’s not breaking it down for me . Like if I drink 2 shakes for breakfast and lunch, what can I consume for dinner especially when it’s telling me to stay less the 50grams per day. Can you help me to understand it a little better I would truly appreciate it thank you in advance

      4. what exactly are you asking? Do you mean 50g of carbs? There are tons of keto recipes and such online. Think large portions of leafy greens and veggies, small portions (1 chicken breast or 5oz steak) mixed in with various plant-based fats like coconut oil, olive oil, avocado or dairy fats like heavy whip or dense cheeses and cream cheese.

      5. Lipase is a digestive enzyme made by the pancreas that helps to break down certain fats. Most people do not need to take lipase supplements because our bodies naturally make ample lipase, but some people with cystic fibrosis or celiac disease may benefit from taking lipase.

    1. I’m usually back out of ketosis within 24 hrs. I can’t stay in ketosis. Need to figure out if I’m still eating too many carbs, not enough fat or too much protein.

      1. Try the App Keto Simple Stupid, it’s a Red circle with a yellow pig, with a red scale inside of the pig! I love it!

      2. too much protein is often a common problem since your body will break down muscle (protein) before it goes to fat. body is looking for path of least resistance for energy, carbs are easiest, then protein, and fats being hardest to breakdown. For myself i found staying between 20-35g of carbs a day was most effective. Careful with fruits and berries as they have tons of carbs (fructose) and though nuts are great for healthy fats, a lot of them still have a moderate amount of carbs too. hope this helps

  2. Would it be beneficial for my 11 year old picky eater with Aspergers and behavior issues to take your product? Is it safe? My husband and I eat keto but he refuses, so I’m looking for alternative options for his brain health and blood sugars.

  3. I still need to know exactly WHEN to take my scoop? In the am? Before a meal? How to incorporate them into fasting?

      1. If you are intermittently fasting, will taking exogenous ketones during the fasting portion of your day mess with your fast, or will it actually improve it? I ask this because my ketones have 5 g carbs – so I would think this would actually reverse the benefits of my fast…

      2. Exogenous ketones break yourfast,but its also up to you. Ico sider andythingwithcalories breaking a fast…but some people do fat fasts, egg fasts, and many different types.

    1. Nutritional ketosis has been shown to be safe and effective for children with epilepsy. And with all of the supplements available there is an increased interest in using exogenous ketones for seizures. Maybe try searching for clinical trials that are using them for children with epilepsy. Or contact one of the teaching hospitals that specialize in this and see if they have any experience using it with their patients? Good luck.

    2. I’ve been instructed to take my ketone supp 15 minutes after a meal, also time it out to be 30 min before you workout (if you’re planning to use it as an energy boost) It’s also recommended to not consume carbs, starches, or sugars 4 hours after taking the ketone supplement.

  4. Can you take ketones and follow a clean eating diet which includes carbs like sweet potatoes, rice, quinoa, etc., and still lose weight?

  5. If you are eating carbohydrates what does your body do with the glucose when you take ketones? It can burn both so does it store as fat because your in ketosis and using ketones for energy instead of the glucose?

  6. I practice a Cyclical Ketogenic diet where I incorporate a higher carb day once a week. The day following a higher carb day, I follow an intermittent fasting day where I do not eat anything (no fats either) for 20-24 hours. I do this as a cellular cleanse (autophagy) as well as a way for my body to get back into ketosis. Would it be helpful to add an exogenous ketone on this particular “fasting” day to get into ketosis quicker? Would I notice better results or is my own nutritional ketosis enough? I am relatively fit with a pretty low fat percentage for my gender and age, but I am always striving for an even leaner “more chiseled” look.

    1. You can take it in the morning or between meals to put your body into an effortless fat-burning mode. You can also try it before/during exercise as an energy drink. It’s also best to take on an empty stomach for peak mental performance and sharper focus. (PK Pro Tip: Mix it in your morning coffee or tea). After eating a meal will also do, to help you boost yourself back into ketosis.

  7. I do intermittent fasting and find that a scoop of the Chocolate sea salt with my coffee makes a great mug of keto “Hot Chocolate”. This helps me stay alert and feeling full until I decide to eat…. at least 20 hours fasting. I also feel like my brain is on fire. I’m a believer.

    Am I doing this right? I am using this to lose weight and even though I have only had this a couple days I feel like it will help.

    Any other advice?

    1. Jackie, yes it sounds like you’re doing it right! If you’re feeling great and your brain is “on fire” as you mentioned, those are great signs!

  8. I am following a low carb diet and have purchased urine ketone dip sticks. It has the colour chart on the side of the container but I’m not sure what I should be looking for to ensure I am keeping the carbs low enough. Can you help?

    1. Hey Susan – the darker the purple color on the urine sticks means the more ketones you are producing. As long as you’re starting to turn that stick purple, you are on the right track!

  9. What should I look for when purchasing ketones? How do I know I am getting what I want instead of some fake? Surely there are ketone imposters just like everything else. And can I get them at the local health food store such as GNC?

    1. Hello Renee! It depends on the benefits you’re looking for and the health goals you’re trying to achieve. All of our Perfect Keto products are quality Exogenous Ketones supplements that can help you get in and maintain ketosis. If you search for each product in the search bar, you’ll be directed to some blogs and guides on when and how to use each product. Let us know if you have any questions along the way 🙂

    1. Being in ketosis actually creates inositol in the body. That’s why when going into ketosis and/or fasting regulates your hormones right away. When I started intermittent fasting, my period showed up in 4 days. Prior to that, I hadn’t seen it in months

  10. soooooo .. am I burning fat (aka like I would be in nutritional ketosis) or am I just adding a bunch of ketones to my body to make it seem like i’m in ketosis? I don’t get how putting exogenous ketones has anything to do with the level of glucose in my body and then switching my primary fuel source to fat?

      1. Hi Alexander – I’m still a bit confused about the artificially raised ketone level from the exogenous ketones. If your body has “temporary artificially raised ketone levels then how does the body use these ketones if you’re not in nutritional ketosis? does it tell your body to get into ketosis faster? is the body now using fat for energy vs. glucose?

        I don’t understand if it’s an actual benefit or a perceived benefit to getting into ketosis if it still takes me 2-4 days to get into nutritional ketosis. Am I actually using fat or just drinking ketones? does that make sense?

  11. I’ve purchased the salted chocolate perfect keto supplement and I can say it’s quite delicious. I drink it 2 times a day and have for 3 days now . I eat a ketogenic diet counting macros with MFP .
    But my body is resisting nutritional ketosis . I register ketones in my urine a few hours after consumption but then they disappear until the next drink…I have been eating a ketogenic diet for several weeks but not in ketosis .I’m looking for any help you can provide for me….

    1. I was resistant, looked at all things to do with carb creep. Just broke my heart. I picked up the book 30 day keto cleanse. I’m not selling any book but it’s a very clean keto plan. Three days in I’m deep into ketosis. Found out heavy cream is not my friend. Just a thought

  12. I’ve been doing this woe 3 days(2nd try). Very low carb, with no sugar, assuming I’m doing keto correctly, will using Perfect Keto help me get into ketosis? Asking because I see this product helps you get back in keto after a cheat or helps you maintain but I’m unclear if it will help you get into keto ? TY

  13. what does your body do if you consume ketones directly after a carb meal? how does it interact with that insulin spike? just curious. Thanks

    1. The insulin spike will cause carbs to be cleared from the blood and stored as fat. Ketones are shown to be used preferentially to glucose when they are both present. The purpose of taking ketones after a carb heavy meal would be to bridge your way back to nutritional ketosis (which will take time and carb restriction).

      1. So if one were to ingest exogenous ketones and raise blood ketone levels (say after a heavy carb meal) to say over 0.5mmol artificially – are you in nutritional ketosis?
        and if not, how do you know if you are in nutritional ketosis.

      2. I have the same question and don’t fully understand your answer. If you have both glucose and ketones in your blood, and the ketones are what gets used for energy, what happens to the glucose? Does it remain in your blood? Thanks.

      3. Hey Anita, your body actually can use both ketones and glucose for energy but your heart and brain actually prefer using ketones over glucose whereas your muscles and other organs go back and forth. Check out this podcast that was recently done with our founder Anthony Gustin – it will help clear a lot of things up!

  14. If you are already in ketosis and not cheating, what benefits would perfect keto or a supplement/ Ketone drink provide? I see a lot of hype around these products but don’t know how you would use them when on plan. Would they help speed fat loss further?

    1. Study after study is showing that cells absorb ketones in proportion to the availability in the blood. This indicates that supplementing with ketones will increase the body’s propensity to use the ketones. I use it as a nice energy boost at work or working out! 🙂

  15. After 12 days of supplementing with ketones drink and a low carb diet, I haven’t seen any fat loss. Is this normal? Can it be that my body just doesn’t respond to this?

    1. Hi
      I’m at that same point as Mia, haven’t loss much weight.
      Would like to know same question?

    1. Hello Amy. Drinking Perfect Keto varies by person. There’s no danger to taking it multiple times per day and multiple scoops. Most people use Perfect Keto between 0-3 times per day and find it best to start slowly and go from there to see what is most beneficial for you.

  16. I am on low carbs diet for last 12 days eating about 20 to 25 g of carbs and urine test shows my ketone level is around 15 mg/dl. I have lost about 18 lbs. If I increase my carbs to 50 g per day, will I still be in Keto stage loosing weight. My goal is to loose 15 lbs more? Please advise. Thank you

    1. Hey Ali, everyone has a different carb threshold and tolerance so you’d just have to test it out and see!

    1. Hi Samantha! There’s no danger to taking Perfect Keto multiple times per day and multiple scoops. Most people use Perfect Keto between 0-3 times per day and find it best to start slowly and go from there to see what is most beneficial for you.

  17. If I have large ketones in my body and have stalled …what should I do? Meaning what is the answer eat more protein more carbs less fat or less protein more carbs I just know that I need my body to be having low ketones to put me back to where I will be burning fat !

  18. What GI complications? I drive a bus all day with limited stops. I really want to try it, but If PK causes upset stomach / diarrhea, that could be a serious deterrent. I’ve been doing low carb for about 2.5 months and down 30lbs. I’d like to go full keto but am concerned about digestive issues.

  19. Thank you for the information provided in the site. I have ordered perfect keto and I look forward to incorporate it in my keto diet.

    Two questions please:

    Would exogenous supplementation with ketones during say intermittent fasting, result in a decreased endogenous ketone production (is there a negative feedback mechanism in place)?

    What is the calorie/energy intake per ketone supplement serving? This will need to be added to the daily calorie intake and would be especially relevant to those on a calorie restricted diet.

    Many thanks

  20. Does anyone know if taking the aromatase inhibitor Exemestane causes slower weight loss or a low ketone reading on a meter?

  21. I have been eating low carb for 2 months. Have lost 11 pounds and building muscle. My urine will show no ketones after several hours after the drink even if I have had no food???

    1. Hi Rhonda, this is actually very common after being keto for a few months and becoming keto-adapted. It just means you are better utilizing the ketones for energy instead of dumping them in your urine.

  22. I have been on ketogenic diet for a month now. I have a blood meter and I seem to stay in the light ketosis range (typically 0.5-0.7). Will exogenous ketones boost me into the suggested ‘Optimal Ketosis’ range?

  23. If you are already on a low cab diet to maintain ketosis…how should this be used in conjunction with that diet.

    Like how often should this be used during that diet for balance

  24. I have heard that people experience hair lose when following a Keto diet, if already following a Keto diet and have stop the hair lose time frame will taking the supplement cause hair lose again?

      1. I experienced hair loss/thinning. I found adding some targeted carbs (half of a small, boiled sweet potato) two nights a week slowly fixed it. I’m female and 44 years old for context if concerned about specific hormonal needs.

    1. Hello Melissa! We highly recommend consulting with your doctor first to see if taking our products or any other supplements would be okay for you .

  25. I am eating Keto and have lost 30 pounds (50 to go), but don’t count carbs religiously and cheat occasionally, usually at social events. Would it be a good idea to use Perfect Keto every morning to help maintain ketosis to make make up for my lack of discipline?

    1. Hi there, you can certainly do that but make sure you are still testing your ketone levels often to see if you are actually in ketosis.

  26. I have a headache, but I don’t know if it’s due to keto flu or a food intolerance (as I regularly get bad headaches from reactions to food). I got some Perfect Keto exogenous ketones to help with the transition, but I’m nervous that they could make my headache worse. Any ideas?

    1. Hi Lilie, I would recommend starting with a small dose (maybe 1/3 to 1/2 scoop) to assess your tolerance and then go from there 🙂

  27. I am in ketosis already because I’m stringently following the ketogenic diet. Would it be dangerous to drink ketones if I’m already in a heightened state of ketosis?

    1. Hi there! We highly recommend consulting with your doctor first to see if taking our products or any other supplements would be okay for her .

  28. I have been eating Keto for two months now. I feel great and I can see a difference in my body compostition but I am not losing weight. I only want to lose 5-7 pounds. I am 54 and in great shape bu the middle age middle fat is my challenge! Is my change mostly water loss? Sometimes I worry I am eating too much fat. Can you eat a lower fat diet, low carb and supplement with Ketones and still lose weight? I dont want to stay Keto forever….but would like to transition back to a healthy balanced, low carb ( not no Carb) lifestyle. I am very active and exercise almost daily.

  29. Hi all,

    Any idea on how to take the Vanilla exogenous ketones?
    I was super stoked to see that my goodies arrived today at work so tried the Vanilla in my morning coffee with unsweetened almond milk and heavy whipped cream as usual. But I could not get over the taste and the smell. Any other suggestions on how to take it as I don’t know if I can take it in my coffee again, had to force myself to drink it. It has a very specific smell and overwhelming taste. But I don’t want to let it go to waste. Help?

    The unflavored Collagen in my other coffee was amazing btw. Creamy, jum!

    1. Hey Danae, I think it just depends on the individual and how your body tolerates it. It’s best to start with smaller doses and work your way up. GI distress would be a indication to take it back a notch. Hope that helps 🙂

    2. You have to be careful with what mineral the ketones are stabilized in. The ketones won’t hurt you. The potassium, calcium, magnesium, and sodium, might! If you are a heart patient, I wouldn’t do it without monitoring your electrolytes very very closely with a cardiologist!

  30. I was wondering why after about an hour of drinking exogenous Ketones they wouldn’t show up in a blood test? Could you shed some light?

    1. Hi Benita, this could be due to a number of different reasons…are you following a ketogenic diet? if so, for how long? Have you taken exogenous ketones before? Are you sure the monitor/strip is valid – may need to do a second check. Could possibly need to check again in another hour. I’d advise testing again tomorrow and see what happens 🙂

  31. Hi,
    Can you please tell me the difference in products, and which one is best for beginner to lose weight.
    Thank you,

    Patty Phillips

    1. Hi Patty! Exogenous ketones help raise your ketone levels to help you get into ketosis. You can then use ketosis as an approach to losing weight. Keto Collagen is great for recovery and soft tissues. MCT powder is a great source of fat for fast energy or a snack 🙂 Good luck!

  32. Even with a ketogenic diet, taking the exogenous ketones only raises ketone level to 0.4. I don’t have a high level of ketones even after a 5 day fast. What would cause this?

  33. The main reason to be using Perfect Keto, it’s to take it as complement for my diet, Atkins Modified to avoid epilepsy, it’s a complement and also could give me some open spaces with the food too; but I don’t have enough info yet, and will appreciate your recommendations. My only restriction are carbohydrates, 10% of the total.

  34. If I’m in ketosis at .9 will this ramp up my ketones and kick me into fat burn? I’m watcging macros and eating keto.

  35. Would this be useful for someone without much fat to loose who is cutting to look as lean as possible for a swimsuit photoshoot a month out?

    I’m a 125lb female at 20% bodyfat and I’ve been doing keto for roughly a year (although there were a couple of sugar filled months in the middle there, opps)

  36. I have hypothyroidism from chemical exposure, I am on natural thyroid and T3. It has been a real struggle, My doctor told me most people in my condition would be severely obese at this stage, but i’m not. I’ve been using perfect keto trying to stay in ketosis, I currently weigh 164 lbs. down from 174. I should weigh 120 but would be content with 135. any suggestions would be great !

  37. Hi! I am fixing to start Perfect Keto and my main reason is for weight loss. I am a little overwhelmed at what products I should purchase. I know I need the Keto Base but should I also get the MCT oil powder? What are the products you recommend to someone starting for weight loss? Thanks a lot!!

  38. Does this product actually put your body into ketosis or just put ketones into your body? I’m trying to understand how I can benefit from exogenous ketones. It just seems to my “uneducated” mind that the only benefit would have to come from a natural state of ketosis. Please help me understand.

  39. I really respect how they are looking out for the consumer over trying to push their product. They are honest and informative in the explanation of how this works, two thumbs up for that! That being said I do really like this product a lot. Its been a huge help in maintaining this lifestyle.

  40. I’ve been trying a keto diet for a couple of months now and only show 5-15 mg/dl on the urine stick. I received my Perfect Keto today, took 1/3 scoop and registered 80!! I’m finally in the purple! Thanks!!!

  41. I have a BS in Biochem, and have been a Medical Lab Tech for several years.

    Can you please explain to me the mechanism proposed for stimulating Ketois by consuming Ketones? The very presence of ketones (a product) inhibits forward reactions of ketosis to generate ATP…

    1. Are you suggesting there is a up-regulating function or positive feedback from ketones and ketone production?
    2.Can you cite any peer-reviewed literature I can read up on?

  42. I ordered the pills and need to know how to use them – I am understanding this is a low cart high fat diet but I need to know what to and not to eat and when? and what?

  43. Can I just use your meal replacement shake to stay in ketosis and lose weight or do I need to make keto meals daily or a few times a week?

  44. I take a lot of vitamins in the morning including a thyroid supplement because my thyroid while not completely out of “normal” range, but at the lowest of the scale, needs a little help! Should I drink this before or after taking my vitamins? How long should I wait in between before consuming either?

    1. Definitely speak with your doctor or a qualified practitioner about this. Some thyroid medications need to be taken away from food. Not only are we not allowed to give medical advice, but it’s impossible to know the answer without knowing what exactly you’re taking. Let us know what your doc says!
