It was like getting the benefits of a five-day fast in just 15 minutes! As my body and brain began sucking up the ketones, I felt a rush of energy and my mind became very sharp and focused in ways beyond what I attain doing an extended fast. But in this case it was the 40g of ketones I had just consumed. Even at the two-hour mark, when I took my last reading, I was still in deep ketosis.

While we know that both MCT Oil Powders and BHB salts are proven supplements to increases ketosis, the winner of a top 5 exogenous ketones list I think should be a true direct form of exogenous ketones – one of the BHB salts. Perfect Keto’s BASE takes the win here. The edge ranking factor is its flavor. With stevia-based flavors such as chocolate sea salt, and the fact that it uses zero additives and actually tastes good, this BHB salt is going to have to take the W. They’re the only 100% coconut MCTs that don’t utilize the goMCT™ form.. this is neither a pro or con. And while it doesn’t have the best bang for your buck compared to the other BHB salts on this list, it’s the most proven as far as happy customer track record and consistent high-quality keto supplements.


Proper sleep is important for hormone function and repair of the body. Not getting enough sleep is tough on the adrenals and blood sugar regulation. Try to get at least seven hours of sleep per night. If you struggle with quality sleep, create an environment that is conducive for rest. This could be keeping your room cooler, turning off all electronic devices one to two hours before bedtime or using a sleep mask.
Plenty of supplements make you a fractionally better sportsman and these are no different. The synthetic exogenous ketones helped Olympic-caliber cyclists cover an average of 411 additional meters during a 30-minute time-trial, which resulted in a two percent increase in overall speed, found a paper in Cell Metabolism. That can be the difference between feeling the glorious tug of the winner’s ribbon across your chest or rolling in with the stragglers.
Exogenous Ketones have been shown in performance studies of both humans and animals to improve metabolic efficiency, which in essence means that your body is using better fuel that burns more efficiently over longer periods of time, and decreases the amount of fuel you need while performing. Where glucose fails (glycogen depletion), ketones pick up the slack!
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
Exogenous ketones are becoming more popular as advancements in scientific research continue to show how they work to improve both health and performance. At first, the only options for delivering exogenous ketones were unpalatable ketone esters; however, exogenous ketones can now be taken in the form of ketone mineral salts that are more palatable and easily blended in water. Making ketone mineral salts involves combining beta-hydroxybutyrate (BHB) with mineral salts such as sodium, calcium, magnesium, or potassium. Before considering whether ketone supplements are a good option, most people immediately look at the salt load, and rightfully so. It is important to take into account the nutritional and health impact of not only the BHB but the minerals that are used to make the product.
Fortunately a new way to test ketosis has been developed - and that is by measuring acetone levels in the breath. This is rather new technology but based on the reports I have seen it does look reasonably reliable. The testing process is simple, you use a device like that made by Ketonix, you breathe into it, wait a minute or so and it will give you a color indicating the state of ketosis you are in. However, there are numerous downsides:
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 [6]. 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 [7].
Fasting blood samples were collected prior to all interventions. Following consumption of study drinks (details below), blood, expired gas and urine samples were collected at regular intervals for 4 h. Water was freely permitted and participants remained sedentary at the test facility throughout the visit. A subset of participants returned for samples 8 and 24 h after the ketone drinks (Study 1).

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.
Those new to keto should be testing to see if their bodies are in ketosis, regardless of method. Testing, in general, is the most objective way to know if you’re in ketosis. There can be some subjective benefits of ketosis: appetite suppression, fat loss, low blood sugar, improvement in mental cognition and focus. But before recognizing these subjective benefits, it’s important to track and measure the level of ketones in the blood to ensure ketosis on a physical level.
Do I still follow a ketogenic diet? Not anymore. I was strict keto for 12 weeks – enough time to experiment and learn about it. I did enjoy parts (lots of fat!) but I don’t see it as a sustainable way of eating, nor did I benefit from it health or sports performance wise (more on this in an upcoming article). But, I was following a strict keto diet – sans carbs. I think if I were to follow a ketogenic diet AND incorporate a regular carb refeed then the results may be different.
When you are in a state of ketosis, the body turns fatty acids into ketones - these appear as beta-hydroxybutyrate in the blood. Measuring blood ketones is regarded as the gold standard and most accurate way to track ketone levels. Testing this way can be expensive, its can cost up to $3 a strip, so if you're testing multiple times a day it can get pricey.
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.

Exogenous ketones don’t seem to improve high-intensity, glucose-intensive exercise, increasing fat burning during steady state exercise but dropping top-end high-intensity performance. Another study found that ketone dieters reduced 50-minute time trial performance in cyclists, though another group of researchers have criticized the methods. Even when a ketone ester didn’t improve performance in the shuttle run to exhaustion and 15 meter sprint repeats, it did reduce the drop in brain function following the exercise.
Are you ready for a very basic metabolism overview? Most modern humans break down carbohydrates into glucose and this then breaks down further and enters mitochondria to produce ATP, which is the energy system of your cells. In other words, you use carbs for energy. When you are on a ketogenic diet, you are breaking down fats into things called ketone bodies, and this is how you provide your body with energy, instead of via carbohydrates. So, you’re either using carbohydrates for fuel or fat for fuel. 
Keep these studies in mind as your body tries to play tricks on you during your first day of fasting.  Even after three days of fasting, health complications are highly unlikely. However, it is important to know about the possible issues that can be caused by fasting. If you choose to incorporate fasting into your daily diet, you typically want to eat every day as well. Occasionally going on a longer period of fasting.
Thank you, Mark! I am an ME/CFS patient, and I have improved quite a bit on a ketogenic diet, which I have been following for the past 3 months. I am slowly losing weight (much needed) and I wondered, does using exogenous ketones inhibit fat loss? I’m trying to balance the benefits of continuing weight loss with benefits in dealing with ME/CFS symptoms. Thank you for any info you can offer!

Should We Use Exogenous Ketones? Ketosis serves a purpose, and it’s probably why we’re able to survive on this planet. Being able to go without eating and use stored fats for energy is a survival tool and possibly far more as we’re now seeing with the keto diet. But it’s probably not a good idea to constantly take exogenous ketones and eat a high carb diet (high blood glucose levels). It’s not natural for the body to have high blood glucose and use ketones. This is a personal opinion, so 
The other potentially important distinction between nutritional ketosis and chemically-induced ketosis is the potential metabolic role played by liver AcAc production and redox status. Although the ratio of BOHB to AcAc in venous blood is typically 80% to 20%, classic studies by Cahill (1975) have observed important hepatic vein and peripheral arterio-venous gradients for this ratio in keto-adapted patients. What these observations imply is that the liver produces a higher proportion of AcAc than is found in the peripheral blood, and that this is due to uptake of AcAc in peripheral cells (principally muscle) with re-release as BOHB. In the process, the reduction of AcAc to BOHB produces NAD+, which is beneficial to mitochondrial redox state and mitochondrial function (Verdin 2015, Newman 2017).
KE was synthesized as previously described [29]. BMS is a novel agent (sodium/potassium- βHB mineral salt) supplied as a 50 % solution containing approximately 375 mg/g of pure βHB and 125 mg/g of sodium/potassium. Both KE and BMS were developed and synthesized in collaboration with Savind Inc. Pharmaceutical grade MCT oil (~65 % caprylic triglyceride; 45 % capric triglyceride) was purchased from Now Foods (Bloomingdale, IL). BMS was formulated in a 1:1 ratio with MCT at the University of South Florida (USF), yielding a final mixture of 25 % water, 25 % pure βHB mineral salt and 50 % MCT. BD was purchased from Sigma-Aldrich (Prod # B84785, Milwaukee, WI).
SHEER Ketones BHB Salts made this top 5 list because they do a good job of avoiding all the common unwanted additives and fillers in BHB salts. It’s good to see we have options to choose from when trying to avoid these types of ingredients. SHEER Ketones’ other ingredients include citric acid, fruit and vegetable juice powder for the color, and “natural flavors.” It uses a stevia leaf extract (Rebaudioside A).

I interviewed Dr. Brianna Stubbs, a ketone researcher with a Ph.D. in Metabolic Physiology from the University of Oxford who is now Research Lead at HVMN, specializing in developing ketone esters. She told me that in terms of science on the ketone salts and their effect on physical performance, one of the most-cited benefits of ketone salts, the scientific studies that have been done show at best no effect on physical performance and that, currently, there is no peer-reviewed scientific research on the ketone salt products on the market.


Ketologie’s PROBHB is a proprietary, “first of its kind” dietary supplement that is totally unique and different to all other exogenous ketone products on the market. Ketologie’s PROBHB is the only BHB supplement specifically formulated with resistant probiotics to assist the body’s transition into nutritional ketosis and simultaneously support immune and digestive health. Our unique formulation optimizes the pathways for improved communication between the brain and the enteric nervous system; providing superior conditions for BHB uptake across the blood-brain barrier. It’s also delicious (slightly sweet and salty) and affordable as we are able to offer it to you directly, rather than via a multi-level marketing program.
Various reasons can motivate you to get into ketosis as part of the Ketogenic Diet. These may range from medical purposes so that you stay healthy, to keeping various ailments away. If you are an athlete, you may get into ketosis to keep your body fit for the upcoming competitions. Some people get into ketosis just to shed some extra fat and keep their bodies in perfect shape. Regardless of the reasons, here are practical tips on how to get into ketosis in 24 hours.
The problem? Exogenous ketone supplements work by flooding your bloodstream with ketones. But unless you’re also eating a ketogenic diet (and producing a steady stream of ketones naturally), those supplemental ketones won’t stick around forever. “The benefit of exogenous ketones is limited due to their excretion through the urine,” explains Madge Barnes, MD, family medicine specialist with Texas Health Family Care. In other words? They’ll only work for a few hours until you pee them out. As a result, you need to keep on supplementing—which can get expensive. Twenty single-serving packets of Prüvit’s Keto//OS MAX Pure Therapeutic Ketones, for example, cost $130. (The company doesn’t specify how often you should take them.)
Full disclosure: after carrying out the background research, I was already, as you might imagine, feeling a little less neutral about these products. You may have noticed a hint of that in part 1 of the 2-part video series we made about the project (watch part 2 at the top of this page!). However, and although this was by no means a controlled scientific study under laboratory conditions, we designed the experiment in a very objective way. The aim was to give the supplements the best possible chance of showing the benefits they are claimed to have.
Not only is Ketōnd considered one of the best on ketone supplements the market it also currently holds favorable ratings, reaching numbers as high as 98 percent in customer reviews. They absolutely love this product and you will too if you give it a try. You will get some incredible results. Whether you are a busy professionals, athlete, on-the-go moms or dads, or college students you too will love this product.

It was explained to me that exogenous ketones inhibit lipolysis (breaking down of fat cells), therefore triglycerides should be expected to go down. They theorize that ketones may promote transfer of triglycerides from blood into cells, which primes the pump for fat burning, but to verify would require conducting biopsies to measure blood versus tissue.

There are numerous benefits that come with living a ketogenic lifestyle. The ketones give your body the much-needed energy and protect you from being affected by different mental conditions such as epilepsy and the Alzheimer’s disease. There is no doubt that ketogenic lifestyle is the surest way of living a healthy and disease-free life. With the tips above, you can get into ketosis in 24 hours effortlessly.

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.
We carried out the testing across five different days, leaving at least two days between the different testing days so that my teammates had time to recover from the physical performance test each time. The reason we needed five days was that we included a placebo (an artificially flavored drink with no caffeine content) alongside the four brands we tested. Our teammates didn’t know that one of the supplements was a placebo. We also gave everyone a different supplement each time, to rule out any improvement in the tests being a result of people simply getting better at those tests over time.
Ketones are produced by the body as a indicator of the body starting to use fat for fuel. Your body then uses those ketones as brain fuel (mostly) , but if you were to have a carb meal it would kick your body out of ketosis (fat burning state) because the carbs are a more easily usable source of energy. So why would you want to add a outside source of energy such as ketones not naturally produced by the body its self? It would kick you out of the fat burning state just like the carbohydrate meal because your body rather spare it’s own energy source as much as possible and also since the outside source ketones are not naturally produce by the body your body does not go into fat burning state because it doesn’t have to go through the natural process to produce its own ketones meaning the body is in its fat burning state since ketones are a by product of fat being used as fuel. Your body has to go through the natural process by itself. Outside ketones are treated as a alternative fuel source so your body has no reason to use fat as its fuel source. Just like carbs. Don’t fall for the scam do your homework it’s science backed up by facts. https://www.t-nation.com/diet-fat-loss/avoid-this-ketogenic-rip-off
When you restrict carbs, the kidneys excrete a lot of sodium. Not replacing this sodium can leave you feeling light headed. I recommend having a big glass of spring water with ½ teaspoon of Celtic sea salt twice a day (first thing in the morning and midafternoon are two times that work well). A long with this, make sure you use a lot of salt on your meals.
Other ingredients: Many of the supplements contain large amounts of caffeine – the supplement we tested from Prüvit contains the same amount as a 16 oz cup of coffee! Some supplements also contain malic acid, which is “known for its ability to increase energy and tolerance to exercise”. This leaves the nagging doubt: if the experiment shows an increase in energy and physical performance, for example, how do we know it is the (expensive) BHB causing the effect and not the (inexpensive) other ingredients?
While the KetoneAid folks have been seeing tremendous success working with elite athletes to improve athletic performance, I thought it would be interesting to quantify the effects of ketone esters on cognitive performance. For the week prior to taking the ketones, I re-established baseline scores in a number of cognitive testing areas using Lumosity*:
It's important to listen to your body when going through the ketogenic process. This means that you should only eat when you're hungry and not every single time you get a craving. It's our obsession with food that causes us to stuff ourselves whenever we feel like it, and you should know by now that it's not healthy to do that. When you make it a point to eat only when you're hungry, you're diminishing any food intake that your body doesn't really need. 
 Effects of beta-hydroxybutyrate on cognition in memory-impaired adults. – Glucose is the brain’s principal energy substrate. In Alzheimer’s disease (AD), there appears to be a pathological decrease in the brain’s ability to use glucose. Neurobiological evidence suggests that ketone bodies are an effective alternative energy substrate for the brain. Elevation of plasma ketone body levels through an oral dose of medium chain triglycerides (MCTs) may improve cognitive functioning in older adults with memory disorders. On separate days, 20 subjects with AD or mild cognitive impairment consumed a drink containing emulsified MCTs or placebo. Significant increases in levels of the ketone body beta-hydroxybutyrate (beta-OHB) were observed 90 min after treatment (P=0.007) when cognitive tests were administered. beta-OHB elevations were moderated by apolipoprotein E (APOE) genotype (P=0.036). For 4+ subjects, beta-OHB levels continued to rise between the 90 and 120 min blood draws in the treatment condition, while the beta-OHB levels of 4- subjects held constant (P<0.009). On cognitive testing, MCT treatment facilitated performance on the Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-cog) for 4- subjects, but not for 4+ subjects (P=0.04). Higher ketone values were associated with greater improvement in paragraph recall with MCT treatment relative to placebo across all subjects (P=0.02). Additional research is warranted to determine the therapeutic benefits of MCTs for patients with AD and how APOE-4 status may mediate beta-OHB efficacy.
Those new to keto should be testing to see if their bodies are in ketosis, regardless of method. Testing, in general, is the most objective way to know if you’re in ketosis. There can be some subjective benefits of ketosis: appetite suppression, fat loss, low blood sugar, improvement in mental cognition and focus. But before recognizing these subjective benefits, it’s important to track and measure the level of ketones in the blood to ensure ketosis on a physical level.
That’s not to say that the supplements don’t work. They very well might. But they could also be useless—or even dangerous, says Christine Palumbo, RDN, Nominating Committee member for the Academy of Nutrition and Dietetics. As of right now, there’s no way to know. “Currently, there’s just not enough evidence from research studies to answer those questions,” Barnes adds.
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.
Medium-chain-triglycerides are fats that are easily absorbed by the body and provide a number of really powerful health benefits. Fast energy, appetite control for better weight loss, increased ketone levels—you name it. They are also one of the most convenient and flexible, too. Add it to a shake, make a smoothie, or take a spoonful of it straight with some water for a quick, healthy keto boost that lasts all day. If you’re the kind of person that struggles to stick to a diet or eat a lot throughout the day, MCT oils are the perfect keto supplement.

We sampled each of the 3 flavors and also mixed in the available Ketōstax and this supplement tasted better than any other we had tried. Ketōnd costs $79.95 for 30 servings which is about $2.67 per serving – which is less than half the price of the leading competitor. Ketōnd’s label and ingredients are 100% transparent, so they disclose everything that is in the supplement – which is only ketones. What we really liked about Ketōnd is that it isn’t part of some Multi Level Marketing company so there are no obligations.
Intense exercise -- more than just fidgeting or pacing -- uses ketones, when glucose is in short supply, which means the body has to create more ketones to replace what you use. This is great for those who are used to a moderate to intense activity level, but intensity is a fine dance between encouraging ketone production and elevating cortisol for the rest of us.

The ketone supplements were associated with a 5.4% decrease in physical performance while the artificially-sweetened, non-caffeinated beverage I used as a placebo was associated with a 20.3% increase: a big difference in favour of the placebo. Before you go rushing out to buy some, remember that this experiment was not performed under fully-controlled, laboratory conditions, and we were working with too small a group to prove that the placebo caused an increase in physical performance. But what we can say is that we couldn’t find any correlation between ketone supplements and an increase in physical performance in this experiment. According to Brianna Stubbs, some of the work currently being done on new kinds of ketone salts is starting to show more promise in relation to physical performance, so there may be better news on this down the line.


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!
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.
Recently, two published studies investigated the effects of ketone salts in athletes (total n = 22).8,9 Performance over a four-minute cycling time-trial and a 150 kJ ( ~11 mins) cycling time trial were compared between ketone salts vs. carbohydrate. In the four-minute trial there was no change in performance, and in the 150 kJ test, performance decreased by 7%. Blood BHB levels peaked at 0.6 and 0.8 mM in these studies.
For the first part of my experiment, I would simply record my blood ketone and glucose levels over a period of two hours after taking the ketone esters. While I am already fairly keto-adapted and can attain nutritional ketosis fairly easily (> 0.5 mmol/L), it wasn’t until the end of my Five-day Fasting Mimicking Diet that I was even close to reaching therapeutic ketosis levels (>5.0 mmol/L).

Interestingly, poly-BOHB has recently been reported to have important roles in mammalian mitochondrial membranes, cell membrane calcium channels, and in exotic functions like protein folding (Dedkova 2014). It exists in a variety of chain lengths, ranging from short to very long. It is not clear if humans can digest and use poly-BOHB consumed in the diet, but in animals, poly-BOHB appears to have probiotic and bowel protective functions. This is a rapidly evolving topic that we will be watching closely.


Exercise or performing an extensive workout during the day is a perfect way to burn all those glycogen reserves in your body. Performing a HIIT or High Intensity Interval Training is a perfect type of exercise to do this. So, the next morning when you are awake, get set on an intense exercise session (remember, in the morning, not the afternoon). This will keep the cortisol level lowered during the evening when you wish to have some rest.
They’ve got enough science behind them to suggest they do work very well indeed, but watch out for the online ads featuring the raspberry ketone fat burners. Their name is little more than a parlour trick because this is not related in any way to ketones, a ketogenic diet or nutritional ketosis. They are merely the natural substance that gives raspberries their sweet aroma and flavour. Just because they’re marketed at the must-have fat burner, doesn’t mean they work and are one of the most widely spread Internet scams. There aren’t any human studies to back up raspberries claims so exercise a handful of caution when choosing your ketone supplier. Make sure they’re reputable, can be held accountable and are Australian made to set yourself up to become leaner while increasing your stamina.

So if you really want to jump start ketosis, do what the prehistoric humans did; don’t eat for 3 to 5 days. Keep the water bottle and multivitamins close and go on a strict fast. It might seem extreme and to a degree it is, but starving yourself will put you into ketosis. No ifs, ands, or buts about it. And it will cause you to lapse into a ketogenic state faster than if you tried to do so by manipulating the foods you eat (replacing carbs with fats). Once starvation has caused your body to transition to a ketogenic state, you can begin to introduce your low carb, high fat keto-friendly foods.

Bottom line: EK isn't the magic pill for instant weight loss. EK triggers ketosis which is a metabolic state where your body burns fat for fuel. EK increases satiety and feeling full, and boosts energy for exercise which helps you lose weight for the long term. You should always aim for the long term and sustainable weight loss and keep the weight off for good instead of looking for a quick fix.


Exogenous Ketones have been shown in performance studies of both humans and animals to improve metabolic efficiency, which in essence means that your body is using better fuel that burns more efficiently over longer periods of time, and decreases the amount of fuel you need while performing. Where glucose fails (glycogen depletion), ketones pick up the slack!

If you truly want to optimize health and performance, magnesium should not be neglected. There is still more research to be done on its potential. Good sources of magnesium include whole grains, nuts, seeds, legumes, green leafy vegetables, and supplements. However, be careful about taking too much magnesium at one time, or else you might end up running to the bathroom in a hurry.
Hi.. I’ve recently started drinking Keto OS Max and have lost about 20 pounds in the past 4 weeks without strictly sticking to the keto diet and have not exercised once. The only issue I have with Keto OS is the price really. I am wondering how the other BHB/MCT products like Ketond and PerfectKeto compare to Keto OS and what product on the market comes closest to the Keto OS recipes beneficial ingredients. TIA
Plasma glucose, free fatty acids (FFA), triglycerides (TG) and urinary d-βHB were assayed using a commercial semi-automated bench-top analyzer (ABX Pentra, Montpellier, France), and insulin was measured using a commercially available ELISA assay (Mercodia, Uppsala, Sweden). Both the pure liquid KS and KE, and a subset of plasma (n = 5) and urine (n = 10) samples from a subset of participants in Study 1 underwent analysis using GC-MS and a chiral column, and the concentrations of l-βHB was calculated using the enzymatically determined concentration of d-βHB and the ratio of the d/l-βHB peaks obtained through GC-MS. Acetoacetate was assayed using an enzymatic method (Bergmeyer, 1965), and breath acetone was measured using GC-MS (Study 1) or with a handheld electrochemical device (Study 2; NTT DOCOMO, Japan) (Toyooka et al., 2013).
Exogenous ketones are not a shortcut to nutritional ketosis, but they do give your body a break from full-time carb usage. They are a tool you can use to get into ketosis if your lifestyle makes it too difficult to do so without them. And they’re also a good way to get an increased edge for those who are very on top of their nutrition and performance.

I am confused on the diet part. I’ve tried ketogenic diets and have experienced great health benefits (I’m diatabetic), but it also helped with sleeping through the night, increased energy, appetite suppression, and balancing of hormones. However forcing myself to eat fat and eliminate God foods like fruit, and trying to keep ratios of fat to protein to carbs was really hard for me. Can supplementing with the exogenic Ketones while having a diet of Proteins, veggies, fruits, healthy fats (avacado, cocnut oil, etc) and some grains (brown rice), produce ketosis?


Should We Use Exogenous Ketones? Ketosis serves a purpose, and it’s probably why we’re able to survive on this planet. Being able to go without eating and use stored fats for energy is a survival tool and possibly far more as we’re now seeing with the keto diet. But it’s probably not a good idea to constantly take exogenous ketones and eat a high carb diet (high blood glucose levels). It’s not natural for the body to have high blood glucose and use ketones.

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.
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!
Compared to our other cellular gasoline (carbs), we can store an unlimited supply of energy from ketones in our body within our fat. When you’re reliant on carbohydrates, you’re forced to keep your tank partly full as we can only store just over 2,000 calories of glycogen from carbs. An empty carb tank results in carb-withdrawal symptoms from not being able to switch into a ketone or fat burning metabolism.
As ketone drinks can deliver nutritional ketosis without fasting, we investigated the effect of food on KE uptake and metabolism. It is well documented that food in the gut can slow, or prevent, the uptake of small hydrophilic hydrocarbons, such as βHB (Melander, 1978; Toothaker and Welling, 1980; Horowitz et al., 1989; Fraser et al., 1995), so decreased gut βHB uptake is probably the cause of lower blood βHB following the meal. Despite higher blood βHB concentrations in the fasted state, the meal did not alter plasma AcAc. This suggests that the rate of conversion of βHB to AcAc may not match the rate of appearance of βHB following KE consumption. Alternatively, meal-induced changes in the hepatic ratio of NAD+:NADH may have altered the conversion of βHB to AcAc (Himwich et al., 1937; Desrochers et al., 1992).
The problem? Exogenous ketone supplements work by flooding your bloodstream with ketones. But unless you’re also eating a ketogenic diet (and producing a steady stream of ketones naturally), those supplemental ketones won’t stick around forever. “The benefit of exogenous ketones is limited due to their excretion through the urine,” explains Madge Barnes, MD, family medicine specialist with Texas Health Family Care. In other words? They’ll only work for a few hours until you pee them out. As a result, you need to keep on supplementing—which can get expensive. Twenty single-serving packets of Prüvit’s Keto//OS MAX Pure Therapeutic Ketones, for example, cost $130. (The company doesn’t specify how often you should take them.)
The metabolic phenotype of endogenous ketosis is characterized by lowered blood glucose and elevated FFA concentrations, whereas both blood glucose and FFA are lowered in exogenous ketosis. During endogenous ketosis, low insulin and elevated cortisol increase adipose tissue lipolysis, with hepatic FFA supply being a key determinant of ketogenesis. Ketone bodies exert negative feedback on their own production by reducing hepatic FFA supply through βHB-mediated agonism of the PUMA-G receptor in adipose tissue, which suppresses lipolysis (Taggart et al., 2005). Exogenous ketones from either intravenous infusions (Balasse and Ooms, 1968; Mikkelsen et al., 2015) or ketone drinks, as studied here, inhibit adipose tissue lipolysis by the same mechanism, making the co-existence of low FFA and high βHB unique to exogenous ketosis.
Divided attention involves processing multiple streams of information. The game involves observing a pond full of koi fish swimming around, and tapping each fish only once to feed it a pellet without feeding any fish previously fed. Each level adds more fish with increasing speed and redirection. It’s similar to pretending to be an air-traffic controller who must keep track of every plane on their radar.

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).
