Onnit is an incredible company that’s making a massive impacts in the lives of athletes in nearly every sport. From Olympic Gold Medalists, to NFL middle linebackers, Onnit has taken athletic performance to a new level. Providing supplements, food, and training equipment, Onnit was an early adopter of the elite performance booster that is exogenous ketones!
Would this be helpful for someone with Hypothyroidism and HPA Axis dysfunction? I started a Keto/IF lifestyle after watching your videos early July and though I feel so much better inflammation wise, I am not seeming to be super fat adaptive as of yet. Would KetoEdge stress out my body with these things going on? I’d love to try it but want to make sure first.
EK use can be compared to the nootropics that have been developed for optimizing focus, memory creation, and faster cognitive performance. While you may not notice this effect on a minute to minute basis if you keep a journal of “forgetful moments” you’ll find that you have fewer of them as time goes on. You’ll also find that you’re able to come up with better ideas, and your workflow is more efficient through the day (10, 11).
We designed a test for each of the chosen benefit claims and enlisted the help of four of our Diet Doctor teammates to try out the supplements and go through the testing. They were Jonatan and Giorgos from the video team, Emőke from the recipe team and Erik from the IT team. We had a mix of people who were naturally in endogenous ketosis during testing, and people who were not.
North Americans typically live pro-inflammatory, pro-disease lives (think about your everyday: likely sitting in a flexed position for hours on end, not enough natural sunlight, not enough movement, artificial food stuffs, artificial colouring, going to bed late, blue light exposure, less in-person contact with our loved ones, late night snacks, the list goes on and on).
1 – If you’re not looking to spend a ton of money up front while testing the ketogenic lifestyle – no problem! For starters, you need to try nutritional ketosis before ever worrying about exogenous supplementation. If you don’t like the diet, it’s not going to matter how many supplements you by. However, if you want to get an idea if exogenous ketones are for you, we would suggest a simple MCT Oil, or a great beginner exo keto like Keto CaNa.
However, it's important to NEVER overlook the power of exercise and of course sticking to a proper routine to get the most optimized results. The most common mistake people make is by treating any keto supplement like a "wonder drug" that will help them shred weight in their sleep. Seriously... how is that even scientifically possible. So if you are thinking about trying out a particular supplement, I would suggest two things:
The second ketone ester compound was developed at the University of South Florida. This is a diester of AcAc and BDO. In rodents, this ketone ester raises blood D-BHB to 1-4 mM and blood AcAc to up to 5 mM.19 There is one published study of this ketone ester in humans; results showed a 2% decrease in 31 km cycling time trial performance.16 This may be due to the high rate of side effects of this ester studied. Other factors may have been low levels of BHB (<2 mM), the short, high-intensity time trial used, or the use of AcAc vs. BHB.

Let’s take a look at some of the facts and misconceptions about three of the minerals used to make ketone mineral salts: sodium, calcium, and magnesium. Potassium is very hygroscopic, meaning that it absorbs water very easily. Therefore, it is only feasible that it can be utilized in liquid formulations.  Thus, one should be cautious if companies say they have potassium BHB salt powder in their product. I’d be very surprised if that’s actually the case.
Some general side effects of your body producing beta hydroxybutyrate is essentially the lull in time it takes to switch from carbohydrate metabolism to fat metabolism, which can take 3-4 days. This can lead to mood swings, fatigue, and general low energy. If you want to skip that step, we recommend taking exogenous BHBs to switch your body over effortlessly.
Every 7 days, animals were briefly fasted (4 h, water available) prior to intragastric gavage to standardize levels of blood metabolites prior to glucose and βHB measurements at baseline. Baseline (time 0) was immediately prior to gavage. Whole blood samples (10 μL) were taken from the saphenous vein for analysis of glucose and βHB levels with the commercially available glucose and ketone monitoring system Precision Xtra™ (Abbott Laboratories, Abbott Park, IL). Blood glucose and βHB were measured at 0, 0.5, 1, 4, 8, and 12 h after test substance administration, or until βHB returned to baseline levels. Food was returned to animals after blood analysis at time 0 and gavage. At baseline and week 4, whole blood samples (10 μL) were taken from the saphenous vein immediately prior to gavage (time 0) for analysis of total cholesterol, high-density lipoprotein (HDL), and triglycerides with the commercially available CardioChek™ blood lipid analyzer (Polymer Technology Systems, Inc., Indianapolis, IN). Low-density lipoprotein (LDL) cholesterol was calculated from the three measured lipid levels using the Friedewald equation: (LDL Cholesterol = Total Cholesterol - HDL - (Triglycerides/5)) [51, 52]. Animals were weighed once per week to track changes in body weight associated with hyperketonemia.
Here we investigated the effects of KE and KS consumption on blood βHB and metabolite concentrations. As we found that KE ingestion delivered a >50% higher plasma concentrations of d-βHB alone, we subsequently determined the reliability and repeatability of ketosis following KE consumption and the effects of concomitant meal ingestion on blood ketone and substrate kinetics. Finally, we determined whether nasogastric infusion could be used for KE administration, given that some patients require feeding in this manner.
Keto-adaption is a complex set of metabolic processes in which the body shifts from using primarily glucose for energy to using largely ketones and fat for energy. Achieving ketosis doesn’t mean the body is maximizing the use of these ketones; it takes longer than a few days for the body to get used to burning fat and ketones as its predominant fuels.
The other option – which is the superior option – is the breakdown of fat into a fuel that can be used by the brain. This is a beautiful solution, because even the leanest individual will have weeks and weeks’ worth of energy stored as body fat. The body breaks down this fat in the liver and converts it into ketone bodies. The brain can then utilise these ketones as a fuel source – forgoing the need for stored glucose or constant consumption of carbohydrates. These ketones can also be used to make ATP.
Methods and Results: In the first study, 15 participants consumed KE or KS drinks that delivered ~12 or ~24 g of βHB. Both drinks elevated blood D-βHB concentrations (D-βHB Cmax: KE 2.8 mM, KS 1.0 mM, P < 0.001), which returned to baseline within 3–4 h. KS drinks were found to contain 50% of the L-βHB isoform, which remained elevated in blood for over 8 h, but was not detectable after 24 h. Urinary excretion of both D-βHB and L-βHB was <1.5% of the total βHB ingested and was in proportion to the blood AUC. D-βHB, but not L-βHB, was slowly converted to breath acetone. The KE drink decreased blood pH by 0.10 and the KS drink increased urinary pH from 5.7 to 8.5. In the second study, the effect of a meal before a KE drink on blood D-βHB concentrations was determined in 16 participants. Food lowered blood D-βHB Cmax by 33% (Fed 2.2 mM, Fasted 3.3 mM, P < 0.001), but did not alter acetoacetate or breath acetone concentrations. All ketone drinks lowered blood glucose, free fatty acid and triglyceride concentrations, and had similar effects on blood electrolytes, which remained normal. In the final study, participants were given KE over 9 h as three drinks (n = 12) or a continuous nasogastric infusion (n = 4) to maintain blood D-βHB concentrations greater than 1 mM. Both drinks and infusions gave identical D-βHB AUC of 1.3–1.4 moles.min.
“Consumption of KETO//OS before exercise can result in significant decreases in oxygen demand and increases in performance. We recommend 30 minutes before a workout. Note: Pre-workout use is recommended after building up to a full dose. The best way to maximize energy, appetite control and sustain energy is to take KETO//OS first thing in morning. To maximize benefits, build up to 1 serving 3 times daily – morning, afternoon and early evening. May be used with carbohydrate supplements if desired or by itself as a non-carb, highly efficient energy source.”
Increased calcium levels in the bloodstream may contribute to the hardening of arteries (atherosclerosis), which in turn can lead to a heart attack.  Calcium from supplements enters the bloodstream in one bolus, whereas we usually tend to get calcium from foods in small doses from the breakdown process. This might explain why calcium from food doesn’t create the same risk that is introduced by calcium supplements. At first glance, it seems to be the case that high calcium intake –at least from supplements–may not be ideal.
Those of you who have tried this form of weight loss before are probably more than aware of how hard it can be to first get your body to adapt to such a dramatic change in your daily intake of food, let alone without the help of a single exogenous ketone supplement. And the situation isn’t made any easier if you use a poor quality ketosis supplement because the wrong ketone product may actually do you more harm than good.
For all studies, the area under the curve (AUC) of blood [βHB] was calculated using the trapezium rule. In Study 3, for each of the three drinks, the initial rate of d-βHB appearance was estimated using d-βHB concentrations at baseline and 30 min post-drink, and d-βHB elimination was estimated using the AUC between the post-drink peak (60 min) and trough (180 min) d-βHB concentrations, with a baseline correction to the value at 180 min.

How to get into ketosis in 24 hours you ask? Can it be done? Yes, it can happen. But only for people who have already been keto-adapted and may have dropped out of ketosis for a short period of time, like after a cheat day. Those people can follow these steps to get back into ketosis quickly. However, if you are just starting keto you have a lot of work to do before your body will let you get into ketosis.
I started this website because it was hard to find trustworthy, evidence-based information about the ketogenic diet. Information that was published and peer reviewed by respected scientific journals. After years of research, I'm sure you'll achieve great results in a healthy way following my advice. I do my best to translate scientific research jargon into plain English. Remember, it's always a good idea to consult a doctor before starting a new diet!

Ketosis is a natural process that more and more people are flocking to these days in an effort to stay fit and healthy. Studies show that it has a host of health benefits and plays a key role in maintaining or changing your physical appearance by helping you lose weight. This is due to the fact that when the body is in a state of ketosis, it converts fat into compounds known as ketones, effectively turning fat into a source of energy.


All data are presented as the mean ± standard deviation (SD). Data analysis was performed using GraphPad PRISM™ version 6.0a and IBM SPSS Statistics 22.0. Results were considered significant when p < 0.05. Triglyceride and lipoprotein profile data were analyzed using One-Way ANOVA. Blood ketone and blood glucose were compared to control at the applicable time points using a Two-Way ANOVA. Correlation between blood βHB and glucose levels in ketone supplemented rats was compared to controls using ANCOVA analysis. Organ and body weights were analyzed using One-Way ANOVA. Basal blood ketone and blood glucose levels were analyzed using Two-Way ANOVA. All mean comparisons were carried out using Tukey’s multiple comparisons post-hoc test.
Ketosis supplements made in poor quality have proven to lead to side-effects such as constipation and increased levels of cholesterol and triglycerides in men. Women may also experience amenorrhea or other disruptions to the menstrual cycle. This is why it is essential to know what combination of compounds you are consuming while you are on this very strict diet. The wrong balance can mess with you in the long term and won't give you the results that you are looking for.

Look around your grocery store, and you’ll soon start to see “Fortified with Calcium” on a variety of different labels, along with calcium supplements everywhere you look. Calcium is essential for cardiovascular health, but several studies have found too much calcium to be associated with cardiovascular events and even death.  One study found that consumption of 1000+ mg of supplemental calcium per day was associated with an increased risk of death from cardiovascular disease in men but not women[13]. Dietary calcium intake (i.e., calcium from incorporated foods such as milk, etc.), on the other hand, was not associated with death from cardiovascular disease in men or women. Additionally, a different study found 1000 mg of supplemental calcium to be associated with an increase in rates of cardiovascular events in women[14].

Hi! My question is, how low must my current daily carb count be in order to benefit from taking your exogenous ketones? I am a 33 year old female, keeping total carbs at 100-125 grams per day. My priority is fat loss, and I do HIIT training 4-5 days a week. I’ll soon be adding in heavier strength training. I don’t function well eating less than 100 total carbs a day. Could this even benefit me? And if it will benefit me, would the befits outweigh the sodium content? I keep my sodium at 2,000 mg a day, as I’m trying to avoid water weight.


Humans in the hunter-gatherer era survived thanks to metabolic flexibility — the body’s ability to use different fuels for energy depending on the nutrients available. This adaptation was vital during a time when the source, quantity, and frequency of food was uncertain[*]. Most of the time, people were fasting, so their bodies ran on ketones, not glucose.
