Hi all…thanks for your articles and info. I am currently on a paleo diet, but want to lose more weight and bring it up a notch w/ ketogenic diet and be in ketosis. Not sure which product is best? Do you take the MCT oil and also a ketone powder. I know it may be difficult at first, but I am up for the challenge as we start the new year and would like to loose 40 lbs by May/June. Please advise as to what products are best so I can purchase. THANKS
Even though there is mixed evidence regarding the association between calcium supplementation and cardiovascular events, there may be other reasons to avoid high calcium supplementation. In one of his studies, Dr. Bolland claimed that calcium supplements do not prevent hip fractures. Rather, they may lead to kidney stones, acute gastrointestinal events, and increased risk of myocardial infarction and stroke. Thus, the risks involved with high-calcium supplementation potentially outweigh the benefits.
In addition to the Weir coefficients being potentially off (which impacts EE), the RQ interpretation may be incorrect in the presence of endogenous or exogenous ketones. As a result, the estimation of fat and glucose oxidation may be off (though it’s directionally correct). That said, the current interpretation seems quite plausible—greater fat oxidation when I had to make my ketones; less when I got my ketones for “free.”
“Though the small amount of carbohydrates in the diets may be more than balanced by the potential sugar production from the large amount of protein to keep the ratio of fatty acid to glucose below the generally accepted level of ketogenesis, the respiratory quotient data suggest another mechanism also” ß (most likely the CPT-1A mutation, which had not been discovered at that time)
Her clients have had similar success. One woman, for instance, has gone from around 170 pounds to 140 pounds since April without making any initial dietary changes. She’s started to gravitate towards more keto foods over time, but still eats her favorite high-carb treats. As for exercise? Her routine consists of a couple of walks each week, Heverly says.
Exogenous ketones are ketones that come in the form of a powder that you mix with water to drink them. Exogenous ketones are controversial in the keto world. The problem is the marketing of them have made some people believe that all they have to do is use this product to get into ketosis. If your blood glucose is too high your body will not use the ketones and they will go to waste.
If you have already mastered the Very Low Carbohydrate (VLC) or ketogenic way of eating, and/or are eating at a caloric deficit, exercising or fasting you are naturally creating the optimal conditions for your body to produce ketones and put your body into nutritional ketosis. By strict adherence to a well-formulated ketogenic diet (complete with higher levels of mineral salts) you should be able to produce all the ketones you need naturally (endogenously). If you are new or inexperienced in ketogenic eating however; or if you or a family member struggles to adhere to a ketogenic diet, then supplementation with exogenous ketones may be very beneficial. Not only will ketone supplements help to mitigate hunger and carb cravings, but they will also help you stave off carb flu symptoms (see below), giving you the best possible chance of long-term success.
Great information. And apparently I have found out what my problem is. I got into Keto a few weeks ago. Transitioned into ketosis after a week, and then had to travel….while I followed a keto diet as best I could, (I took your powdered MCT Oil with me and it is great), but I did fall out of ketosis. Now it’s been 2 weeks and I can’t seem to get back into ketosis.
There are many places where you can buy ketone supplements especially online. You have Amazon, Craigslist, and eBay to name a few but the thing with that is, they are often over-priced compared to the actual costs from the direct manufacturer. If you buy ketones directly from the official website of the product or brand, you are likely to get a way better deal than buying from any third-party seller that you might bump into on the internet.
While it usually takes 2-7 days for your body to enter into a state of ketosis on a ketogenic diet, there are a few things you can do to kickstart this process. It isn’t guaranteed but it will assist in the process, and may work in extreme cases. Intermittent fasting, exercise, proper sleep, a strict high-fat-low-carb diet, and supplementation can all help fastened the transition process. Whether you’ve fallen out of ketosis after a cheat weekend or maybe you’re somebody who have just started out on your keto journey – here is how to get into ketosis in 24 hours.
Ketogenic Diets and Physical Performance – Impaired physical performance is a common but not obligate result of a low carbohydrate diet. Lessons from traditional Inuit culture indicate that time for adaptation, optimized sodium and potassium nutriture, and constraint of protein to 15–25 % of daily energy expenditure allow unimpaired endurance performance despite nutritional ketosis.

Hey Staci, great to hear you’re getting back into it! To answer your question, it really depends on the individual but there are definitely things you can do to get back into ketosis faster – working out to deplete your glycogen stores or implementing intermittent fasting into your regimen – these are 2 common ways that should kick start you back in the right direction!
Ketogenesis is the metabolism of fatty acids by β-oxidation. 4 This process gives acetyl CoA which then leads to β-hydroxy-β-methyglutaryl-CoA (HMG-CoA) as seen below5. HMG-CoA converts into Acetoacetone which can switch back and forth to BHB. Acetoacetone to Acetone conversion is irreversible (on the left below). Acetoacetate and BHB (via acetoacetate) are used to produce energy when converted back into acetyl-CoA within a cell’s mitochondria whilst Acetone is excreted in the breath and urine.4
I simply use this to attempt to reduce the symptoms of the "keto-flu" when I'm entering ketosis after blowing my carbs out. The holidays are particularly bad for falling off the keto band-wagon. I've used this three times now to transition back into ketosis and I can report that it does seem to reduce the effects of the keto flu (headache, weakness) that I'd normally experience transitioning back into a low-carbohydrate diet. I typically take it for 3 days and then stop because by that time I'm in ketosis again, but I'd imagine you could take it longer.
I just started down the Keto path with the help (hopefully) of Ketond. My problem with all the websites and info I’ve seen is that no-one says how often you should take the EK. The packages say the serving size is one scoop…. but how many servings per day? It (Ketond) also says one serving will put you in Ketosis for 3-5 hours – so, does that mean you should take another serving after the 3-5 hours to stay in Ketosis?
There are many different variations of intermittent fasting as well. Dr. Dom D’Agostino, the well-known ketogenic diet researcher, suggests doing a longer intermittent fast for 3 days, 3 times a year. This means not eating for 3 days, and eating normally until the next fast. Daily intermittent fasts are recommended as well. He says that it is ideal to have one to two meals after fasting for most of the day to reap the benefits of intermittent fasting every day.
The liver is always producing ketones to some small degree and they are always present in the bloodstream. Under normal dietary conditions, ketone concentrations are simply too low to be of any significant benefit. A ketogenic diet and exogenous ketone supplements will increase the amount of ketone in your body. The idea that ketones are “toxic” is ridiculous. Ketones are a normal physiological substance that play many important roles in the human body.
Over the 28-day experiment, ketone supplements administered daily significantly elevated blood ketone levels without dietary restriction (Fig. 2a, b). Naturally derived ketogenic supplements including MCT (5 g/kg) elicited a significant rapid elevation in blood βHB within 30–60 min that was sustained for 8 h. BMS + MCT (5 g/kg) elicited a significant elevation in blood βHB at 4 h, which was no longer significant at 8 h. BMS (5 g/kg) did not elicit a significant elevation in blood βHB at any time point. For days 14–28, BMS + MCT (10 g/kg) and MCT (10 g/kg) elevated blood βHB levels within 30 min and remained significantly elevated for up to 12 h. We observed a delay in the peak elevation of blood βHB: BMS + MCT peaked at 8 h instead of at 4 h and MCT at 4 h instead of at 1 h. Blood βHB levels in the BMS group did not show significant elevation at any time point, even after dose escalation (Fig. 2a). Synthetically derived ketogenic supplements including KE and BD supplementation rapidly elevated blood βHB within 30 min and was sustained for 8 h. For the rats receiving ketone supplementation in the form of BD or the KE, dosage was kept at 5 g/kg to prevent adverse effects associated with hyperketonemia. The Precision Xtra™ ketone monitoring system measures βHB only; therefore, total blood ketone levels (βHB + AcAc) would be higher than measured. For each of these groups, the blood βHB profile remained consistent following daily ketone supplementation administration over the 4-week duration. (Fig. 2b).
Ketone Esters: These are not normally found in the body, but exogenous ketone esters convert into BHB once it is in the body. They are also synthetically (lab) made compounds that link an alcohol to a ketone body, which can then be metabolized by the liver into a ketone. They are like ketone salts on steroids as they have 5-10 time more BHB per serving/maximum daily intake than ketone salts. To date, pure ketone esters have been very expensive to produce and have only been available to researchers, elite athletes (Tour de France cyclists), and the US Department of Defense (people have spent more than $20,000 to have an independent lab produce a single serving!).
Exogenous ketones drinks are growing in popularity as a method to elevate blood ketone concentrations and mimic a ketogenic diet without the need for dietary changes (Ari et al., 2016; Cox et al., 2016; Kesl et al., 2016; Caminhotto et al., 2017; Evans et al., 2017). The present study describes the pharmacokinetic and pharmacodynamics properties of ketone ester and salt drinks in humans at rest, and characterizes the effects of a prior meal, which is pertinent to use as a dietary supplement. The main findings were that KE drinks elevated blood d-βHB > 50% higher than KS drinks, the latter significantly increasing blood l-βHB, which was metabolized more slowly by the body. Both drinks had similar effects on FFA, TG, glucose and electrolyte concentrations, although with disparate effects on pH. A prior meal decreased total blood d-βHB appearance after a KE drink. Finally, either three KE drinks or nasogastric feeding effectively maintained nutritional ketosis over 1 mM for 9 h.
Ketone Salts: While the body uses and makes BHB ketones salts naturally, in supplement form ketone salts are synthetically (lab) made compounds that combine sodium (and/or potassium, calcium, or magnesium) with BHB. The salt is used to raise the pH and make things less acidic. Currently, all ketone supplements on the market are made from ketone salts. While they raise ketone levels, most people will only experience mild nutritional ketosis (~0.6-1.0 mmol/L).
Supplemental BHB’s are ideal for people new to the ketogenic way of eating. The changes that happen in your brain and body when adapting to a VLC diet are both immediate and profound. For example, our kidney’s start processing minerals salts much more efficiently. Ironically, after years of being advised to decrease our intake of salt (sodium), it turns out that for people transitioning away from the Standard American Diet (SAD diet) towards a lower carb or ketogenic diet there is actually a need to increase dietary mineral salts such as potassium, sodium, magnesium and calcium. During the process of becoming keto-adapted, it is very important to increase your intake of these essential minerals, in order to prevent the onset of unpleasant symptoms (known as “keto flu”).
Skipping breakfast on a keto diet is a popular way to boost ketone levels. Despite the age-old myth that breakfast is the most important meal of the day, research shows that breakfast skipping is not only safe but beneficial. Skipping breakfast causes intermittent ketosis and also suppresses appetite . Make sure your next meal of the day isn't too late in the evening as studies show that eating meals late at night causes weight gain and impairs fat metabolism .
Exogenous ketones have become a popular nutritional supplement since their introduction in 2014. Unfortunately there is a lot of inaccurate information and marketing you have to read through to find the truth about them. This article does the hard work for you. It gets right to the true benefits and drawbacks of exogenous ketones supported by research studies.
MCT Oil is a keto supplement that helps your body make ketones. The oil contains pure medium-chain triglycerides (MCTs), which are types of fatty acids that your body prefers using for immediate energy. Unlike long-chain fatty acids, MCTs don't require enzymes and bile for digestion and they go straight to the liver where they are used for making free fatty acids or ketones. Studies on MCTs show that they promote weight loss .
