The year before last I somehow full on Rocked at the keto diet lost 100lb, and was taking adderall. I am transitioning back into it again also back on the adderall, but i seem to have no energy and last time my doc did my blood work i was only 16% hydrated. Obviously it’s a huge problem for me, staying hydrated and trying to lift the fogginess. I am type 2 diabetic and my doctor is on board with me trying all to keep my sugars down YEAH!!! I have never tried any exogenous product. My body seems to not absorb much vitamins. Can anyone make a or any suggestion to me as to how to get this under control?
There are three types of ketones produced when you’re on ketogenic diet: acetoacetate, beta-hydroxybutyrate (BHB), and acetone. The kinds that you’ll find in your supplements are BHB because your body can readily use and absorb them. This means that not all ketones are created equal and there are several different types, each with unique properties that are worth considering when shopping.
Today, 4/27, I received the Peaches & Cream. I was reluctant to purchase, but I didn't want to wait until Saturday for the Salted Chocolate. After dinner, I mixed it in water, added heavy cream, put it over ice. Delicious!!! I believe these products work bc I can still eat up to 50-100g of carbs on a lax day and still drop weight since it keeps me in Ketosis.

It’s not clear that the Weir coefficients used to estimate EE are relevant for someone in ketosis, let alone someone ingesting exogenous BHB. (The Weir formula states that EE is approximated by 3.94 * VO2 + 1.11 * VCO2, where VO2 and VCO2 are measured in L/min; 3.94 and 1.11 are the Weir coefficients, and they are derived by tabulating the stoichiometry of lipid synthesis and oxidation of fat and glucose and calculating the amount of oxygen consumed and carbon dioxide generated.) While this doesn’t impact the main observation—less oxygen was consumed with higher ketones—it does impact the estimation of EE and substrate use.

Beta-hydroxybutyrate (BHB) is a ketone body produced in the liver naturally under conditions when glucose isn’t very available. Other types of ketones produced via the restriction of dietary carbohydrates are acetoacetate and acetone. A VLCHF or ketogenic diet provides the optimal conditions for this process. Fasting, exercise and/or basic caloric restriction are all also methods for promoting ketogenesis (literally, the making of ketones).

After a few days of fasting, or of drastically reduced carbohydrate consumption (below 50 g/day), glucose reserves become insufficient both for normal fat oxidation via the supply of oxaloacetate in the Krebs cycle (which gave origin to the phrase ‘fat burns in the flame of carbohydrate') and for the supply of glucose to the central nervous system (CNS).4


The best time to start a one day fast is in the evening (neither morning nor the night) – preferably, around 6 pm. It won’t make you lose your vital energy during the daytime workouts, nor does it let you sleep with undigested foodstuff in your stomach. Taking late meals and sleeping with undigested food doesn’t allow your body to rest. So the natural healing mechanism of your body fails during the sleep time as the entire resources are busy digesting your food.


Despite the recent growth of the ketone salt market, there is very little published work analyzing the effects of these products on any biomarkers or performance measurements in humans. Several studies have been carried out in rats,6,7 with blood BHB levels being relatively low (<0.5 mM) post-consumption of salt drinks. In humans, ketone salts provided peak D-BHB levels of 1 mM, whereas the same amount of BHB in a ketone ester (BD-BHB) raised blood BHB to 2.8 mM.5
Hypoglycemia: why not to be concerned – Taking exogenous ketones can drive blood glucose levels quite low, but you are not likely to feel the typical symptoms of hypoglycemia. This is because when ketone levels are high enough, they dominate as fuel in the brain; hence, you will feel just fine despite having low blood glucose. A highly-cited study by George Cahill, found elevated ketone levels could protect fasted participants when they were administered insulin to induce hypoglycemia.
Our mission at Ketologie is to help educate and assist people in transitioning to a ketogenic way of eating for life. Primarily, we support people achieving this via adopting a VLCHF or ketogenic way of eating. Exogenous ketones can however play a useful role in transitioning to and maintaining a ketogenic lifestyle, and so we have exhaustively researched and developed a unique, “next level” ketone supplement that focuses specifically on optimizing health via the gut-brain axis.
As I mentioned before, this was by no means a scientific experiment carried out under lab conditions, and this means we can only draw tentative conclusions from any of the data. Nonetheless, carrying out the testing in the way described above should give most people a good idea of how well the ketone supplements show the noticeable benefits they are marketed to have and provide a clear enough basis for a decision on whether or not to buy them.

I’m not sure whether I am leto-adapted but have been following the keto program for about 6 weeks. The scale and the eye confirm I have been burning fat. I’ve been using ketostix to keep track of ketones as I don’t prefer to prick my fingers to get blood measurements. I have reached my weight loss goal and planning to transition to maintenance in the next couple of weeks. I’m curious if exogenous ketones will be aid in maintaining my weight.


I am a little confused. I can see how EK’s can help up the state of ketosis, but as far is weight loss is concerned, aren’t the ketones you produce naturally created by the breaking down of your own fat? If I supplement with exogenous ketones, will that slow the natural creation of ketones? Especially if I am eating a higher amount of carbs. Would exogenous ketones speed fat loss, or slow it?
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.
However, with the ketone esters, the effects are nearly immediate, and my entire body was humming throughout the entire day, but not in a jittery way. I was full of mental and physical energy that lasted without any sort of crash (it was a gradual taper). During my cognitive tests, things felt almost effortless as I played the various games. After my experiment was complete I continued writing code for several hours, then went to the gym to work out. I did forget to each lunch though, so there must be some suppressive effect on appetite.
Ketones naturally exist in the body, being created during the process of fat metabolism and are therefore safe to consume even during pregnancy or breastfeeding. Supplements such as Ketologie’s PROBHB are simply providing ketones from an external (exogenous means literally ‘outside of the body’) source. However, if you suffer from any medical conditions and/or are on medications, it is always advisable to consult your health care provider prior to starting any new nutritional or dietary supplement.  
Hi. Thanks for the informative article! I have fallen down the exogenous ketone rabbit hole for the last 2 days trying to figure everything out. I am currently on a nutritional ketonic diet but after 8 months, I am finding it difficult to stay on it 100%. I would like to remain on a low-carb diet, but also have a little more flexibility in my food choices. If you take the expense out of the equation, which product would you recommend for someone who wants to use ketosis as a method of weight loss? Thank you so much.
We tested the effects of 28-day administration of five ketone supplements on blood glucose, ketones, and lipids in male Sprague–Dawley rats. The supplements included: 1,3-butanediol (BD), a sodium/potassium β-hydroxybutyrate (βHB) mineral salt (BMS), medium chain triglyceride oil (MCT), BMS + MCT 1:1 mixture, and 1,3 butanediol acetoacetate diester (KE). Rats received a daily 5–10 g/kg dose of their respective ketone supplement via intragastric gavage during treatment. Weekly whole blood samples were taken for analysis of glucose and βHB at baseline and, 0.5, 1, 4, 8, and 12 h post-gavage, or until βHB returned to baseline. At 28 days, triglycerides, total cholesterol and high-density lipoprotein (HDL) were measured.
This is probably one of the most understood notions of a true ketogenic diet (and the difference between a keto diet and a low carb diet). An optimal ketogenic diet will be low in carbohydrates AND protein. Many people who have experimented with low carb dieting simple reduce carbs and increase protein. A big reason behind this is due to the misconception that ‘’excess fat is bad – which is untrue, more on this HERE). However, excess protein can be converted to glucose (blood sugar) through a process called gluconeogenesis.
Administration of ketone supplementation significantly reduced blood glucose over the course of the study (Fig. 3a, b). MCT (5 g/kg) decreased blood glucose compared to control within 30 min which was sustained for 8 h at baseline and at week 1. MCT (10 g/kg) likewise decreased blood glucose within 30 min and lasted through the 12 h time point during weeks 2, 3, and 4. BMS + MCT (5 g/kg) lowered blood glucose compared to control from hours 1–8 only at week 1. BMS + MCT (10 g/kg) lowered blood glucose compared to control within 30 min and remained low through the 12 h time point at weeks 2, 3, and 4. Rats supplemented with BMS had lower blood glucose compared to control at 12 h in week 4 (10) (Fig. 3a). Administration of BD did not significantly change blood glucose levels at any time point during the 4-week study. KE (5 g/kg) significantly lowered blood glucose levels at 30 min for week 1, 2, 3, and 4 and was sustained through 1 h at weeks 2–4 and sustained to 4 h at week 3. (Fig. 3b).
The product does not work. I have taken one scoop daily and for last two days two scoops (once in the morning and once in the night). I also do intermittent fast i.e. no food from 8 pm - next day 2 pm other than this powder in the morning. My food is 1500 calories with 60% fat, 30% protein and 5% carbs. I used to achieve ketosis naturally prior to using the powder. But now, there is no ketosis. This product does not work. I am wondering how on earth did they pick up so many reviews, unless it is faked marketing.
Blood glucose concentrations are decreased during both exogenous and endogenous ketosis, although by different mechanisms. During endogenous ketosis, dietary carbohydrate deficit is the underlying cause of low blood glucose, along with reduced hepatic gluconeogenesis and increased ketone production (Cahill et al., 1966). With exogenous ketosis, carbohydrate stores are plentiful, yet ketones appear to lower blood glucose through limiting hepatic gluconeogenesis and increasing peripheral glucose uptake (Mikkelsen et al., 2015). One clinical use of the ketogenic diet is to improve blood glucose control, yet the elevated blood FFA may increase the risk of heart failure (Holloway et al., 2009). Thus, the ability of exogenous ketones to lower blood glucose without elevating blood FFA concentrations could deliver the desired effect of the diet, whilst also decreasing a potential risk.
Great question. So if you are already in nutritional ketosis from your diet, exogenous ketones would still help raise ketone (energy) levels when you want that (maybe for focus at work or energy at the gym. They also help get you back into ketosis after cheat meals and skip the “keto flu” which is the period when your body is using up stored glycogen.
Ketones may be a better source of fuel than glucose, and a far better beverage than Fruitopia, but it's a question of whether or not you can spare the extra fuel. Because just like adding sugar to a diet, it's like pressing pause on the fat burning process since the body preferentially burns it for fuel. Adding ketones to the diet does the same thing.
The famous keto-breath is powerful enough to throw shade on your increasingly ripped rig. The mouth-based ketones are released when your body scalds fat are responsible for the pong. Going into ketosis by changing your diet means your body doesn’t have carbs as a fuel source, so you’re using fats and proteins for energy, which fuels the potency of the fireworks seeping from your grill. The same can happen when taking supplements, but not by the same degree – proving that changing your diet it obviously a more potent fat burning tool. A lot of people also report gastric distress, so you could offend those you’re co-habituating with. What’s more, they can have a slight diuretic effect, which can deplete your magnesium, potassium and sodium stores, so make sure your levels are topped up when you’re out for a extra long exercise stint. Research in Nutrition and Metabolism on animals, found there were no negative side effects, but whether this extends to humans is still up for discussion. Fortunately, you’re more likely benefit from the upsides such as improved endurance, appetite suppression and fat burning.
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
-       Take ketone supplements (therapeutic ketosis): A second option is to consume ketones in the form of a supplement. Supplements like Perfect Keto Ketone Salts that provide the exact same ketone bodies that are produced naturally in the body. And while supplements are not a complete replacement for the benefits of ketones produced through diet, they do lower the barrier by allowing anyone to start benefiting from therapeutic ketones.
If given all as a single salt, 50 grams per day of BOHB would mandate daily intakes of 5.8 g Mg++, 9.6 g Ca++, 11.0 g Na+, or 18.8 g K+. Even if divided up carefully as a mixture of these various salts, it would be problematic getting past 30 grams per day of BOHB intake. And again, most of the currently marketed ketone salt formulations are made with a mix of the D- and L-isomers of BOHB, so the actual delivered dose of the more desirable D-isomer is considerably less. The other concern with the salt formulations is that, as the salts of weak acids, they have an alkalinizing metabolic effect that might have a modest but cumulative effect on blood pH and renal function.

In Summary, I think it’s important to do your own research and draw your own conclusion about the long term risks of ketosis. For some people, a ketogenic diet may be a necessity given their health situation. For those of us who do not suffer from such health conditions I would present the question ‘why do you want to follow a strict ketogenic diet for an extended period’, and then follow this up with ‘are the potential risks and sacrifices worth the benefits?’


Emerging evidence supports the therapeutic potential of the ketogenic diet (KD) for a variety of disease states, leading investigators to research methods of harnessing the benefits of nutritional ketosis without the dietary restrictions. The KD has been used as an effective non-pharmacological therapy for pediatric intractable seizures since the 1920s [1–3]. In addition to epilepsy, the ketogenic diet has elicited significant therapeutic effects for weight loss and type-2 diabetes (T2D) [4]. Several studies have shown significant weight loss on a high fat, low carbohydrate diet without significant elevations of serum cholesterol [5–12]. Another study demonstrated the safety and benefits of long-term application of the KD in T2D patients. Patients exhibited significant weight loss, reduction of blood glucose, and improvement of lipid markers after eating a well-formulated KD for 56 weeks [13]. Recently, researchers have begun to investigate the use of the KD as a treatment for acne, polycystic ovary syndrome (PCOS), cancer, amyotrophic lateral sclerosis (ALS), traumatic brain injury (TBI) and Alzheimer’s disease (AD) with promising preliminary results [14–26].
If you’re wondering how to get into ketosis in 24 hours, and whether it’s even possible with such a short turnaround time, then combining a keto diet with intermittent fasting is a must. I am a massive advocate of not only the ketogenic diet but also the practice of daily fasting – I swear by it! It’s not for everyone as it does require a lot of discipline to pull off. But if you can commit to it, the benefits in my opinion are well worth it. So you may be wondering what intermittent fasting is? Well, it’s the practice of performing a daily fast from food and (caloric) drinks for at least 16 hours of the day.
I heard a rep from Perfect Keto on a podcast and your Exogenous Ketones. I ordered and received it the other day. I see from this article that I should not do a full scoop at once, but break it up in a day. Good to know. I had about a half scoop before I worked out this morning and could tell I had more energy. Loved that. Just curious….any ideas how long it will take me to get back into ketosis and fat burning?? (I know it depends on what I eat, but a general idea that I promise not to hold you too! (I’m actually missing having ‘keto breath!)
The main distraction which we have these days in our lives are the gadgets. Therefore, in order to fall asleep early, you need to make sure that you turn off your phones, tablets, computer, TV etc… at least 30 minutes before bedtime. This helps avoid insomnia as well as keep you away from the bright blue light which can interfere with your biorhythm.
Caveat emptor: the following post doesn’t come close to answering most of these questions. I only document my experience with BHB salts (and a non-commercial version at that), but say little to nothing about my experience with BHB esters or AcAc esters. But it will provide you will some context and understanding about what exogenous ketones are, and what they might do for athletic performance. We’ll likely podcast about the questions and topics above and cover other aspects of exogenous ketones in more detail.
