This molecule is quite essential if you are using your own fat for fuel, or taking BHB as an exogenous ketone supplement to increase energy production — essentially to be in nutritional ketosis. If you’re not certain about what ketones are or what nutritional ketosis is, you should back up a little bit and read more about that on my company site, Perfect Keto.
For example, the popular Raspberry Ketones supplement is far different than what we have been discussing in this article. Raspberry ketones are unrelated to the ketones that are produced in the body and are not the same as the ketone salts that have been covered above. There are some limited studies that indicate raspberry ketones may be helpful for weight loss, but they are inconsistent. Raspberry ketones are the molecules that give raspberries their scent and flavor, and in some cases, aren’t even derived from raspberries at all.
Beta-Hydroxybutyrate (BHB) is naturally ketone body that is produced when free fatty acids are broken down in the liver. The other two types of Ketone bodies are acetoacetate (AcAc) and acetone. Ketones provide pure energy to fuel the human brain and other tissues. The elevation in ketones in your blood have been a rapidly emerging area of research and studies are continuing to show improvements in performance, brown adipose tissue, and several other possible applications.
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.)
Hi- Thank you for this super helpful post. I’m new to Keto and supplementing Keytones. I just got the Julian Bakery Keytones and am curious about how to take them as there are no instructions on the packaging. Indeed the website has a diet plan to follow with the keytones but I am very suspicious of it because it is 0 fat which I believe is not healthy for brain or body and given that I have soft tissue and joint issues, I try to eat enough fat daily. I want to lose weight and I crossfit 5 days per week. So how do I best start with using the keytone supplements? I took a scoop full yesterday when they arrived (in the early afternoon) but hadn’t yet eaten and I think that was a mistake because I had immediate diarrhea which lasted a few hours, even after eating.
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. 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.
I had the chance to interview Dr. Ryan Lowery, Ph.D. about this in person. He performs some (not peer-reviewed) research on different brands of ketone salts and is listed as one of the “specialists” on Prüvit’s website. He suggested that we had perhaps ran the tests too long after the supplements were taken, stating that blood ketones tend to peak at 30 minutes. This is, however, not what Prüvit themselves state in their article on the 59-minute test, or the promise to reach ketosis in 60 minutes on the Kegenix Prime packaging. Plus, do you really want to spend up to $390/month on a product that gives you the benefits of ketosis for half an hour?
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
Now I can make a full review on these Perfect Keto products. I purchased the Salted Chocolate first. When I got it, I was mixing it with room temperature coffee and outing it over ice and adding heavy whipping cream. I hated the taste but kept making it that ways bc it got me 5lbs lost in one week. One day I got lazy and just mixed it with water and added heavy cream and it was delicious!! I highly suggest just mixing with water, adding heavy cream and over ice. I've lost 10 lbs in 15 days.
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.
Over the past couple years, I’ve tried a number of ketone supplements, generally to enhance a longer fast or to offer an edge before one of my Ultimate Frisbee evenings. This Kegenix variety is one I’d recommend. I’ve also used Quest Nutrition MCT oil powder with good results as well, but there are plenty of other solid formulations to choose from.
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.
Testing BHB levels in the blood is simple but can get pricey if you are doing it many times a day. The Precision Xtra blood glucose and ketone meter is a good buy at $28-$30. The expensive part is the ketone test strips here which can cost $4 each. If you are looking at testing yourself every day it is going to cost you $120 a month and the $30 meter. Here is a starter kit you can get on Amazon.
This was a big surprise. We were at the very least expecting that drinking a ketone supplement would cause blood ketones to rise, but an average increase of 0.33 mmol/L is very small. The supplement associated with the highest average increase in blood ketones was Prüvit’s Keto-OS Max, but it was only an increase of 0.6 mmol/L. Brianna Stubbs, the ketone researcher I consulted with, agrees that an increase of below 2.0-3.0 mmol/L is unlikely to be of much use.
Exogenous ketones cause the body to rely less on fat as fuel (see Fig 3). Fat takes longer to metabolise for energy than muscle glycogen. This is why fatty acids are not the preferred fuel under heavy exercise. This could be useful for keto-adapted athletes performing high-intensity cardiovascular or strength training.12 This is particularly useful for the Keto-adapted athlete who wants to undergo high-intensity cardiovascular or strength training.
When you start this process, changes in your daily food and drink intake are designed to increase the amount of healthy fats being burned by your liver, which produces and releases more of these endogenous ketones into your blood stream. When breastfeeding, the female body naturally burns more fat to produce the endogenous ketones, which is an infants resource to the nutrients they need for their young minds. As an adult, a lot of us have substituted the goodness of this compound for more sugar fueled energy. However, I'm sure there are many of you that are wondering right now, "does keto work at all and if so how long does ketosis last?" After numerous tests and studies, it has been recognized that it indeed does work and has been proven to have long lasting effects, so you can rest easy and maybe throw away those weight loss pills that claim instant results but don’t seem to do much.
I I started off interested in this product because it was cheaper than another popular Keto drink that I have known people to loose weight on. I have been drinking this about 2 weeks every morning on my way to work and I have never gotten the shakes jitters or felt a crash. I have also noticed my clothes to fit more comfortably as well. I do feel somewhat better taking this product I don’t know if it’s a mental thing but I will definitely purchase more and keep drinking it to hopefully see more difference
A meal high in carbohydrate and calories significantly decreased peak d-βHB by ~ 1 mM (Figure (Figure4A)4A) and reduced the d-βHB AUC by 27% (p < 0.001, Figure Figure4B).4B). There were no significant changes in d-βHB Tmax (fed = 73 ± 6 min vs. fasted 66 ± 4 min). Despite the differences in d-βHB kinetics after the meal, there were no effects of food on urinary ketone excretion (Figure (Figure4C),4C), plasma AcAc (Figure (Figure4D)4D) or breath acetone (Figure (Figure4E)4E) following KE ingestion. Plasma AcAc kinetics followed a similar time course to d-βHB, with the ratio of blood d-βHB: AcAc being 6:1 when KE drinks were consumed whilst fasted, and 4:1 following the meal. As observed in Study 1, breath acetone concentrations rose more slowly than blood ketone concentrations, reaching a plateau at 150 min and remaining elevated for at least 4 h (Figure (Figure4E4E).
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
I’m often asked if it’s necessary to buy and use keto products like urine sticks. They’re small test strips that you dip in urine to see if your body is producing ketones (and therefore indicate if you’ve entered ketosis.) There's very little information on how to know that you are in ketosis other than using these ketones supplements because they are as accurate as can be in determining your current state. Outside of that, you can only guess if you are in it or not by your body's performance.
Exogenous ketones (also known as ketone supplements) and well-formulated ketogenic diets share at least one thing in common. They both result in increased circulating concentrations of beta-hydroxybutyrate (BOHB), but ultimately are associated with very different patterns of ketosis, as well as differing metabolic and physiologic outcomes. In short, they should not be assumed to have equivalent effects simply because they achieve similar BOHB blood levels. Having said that, there are many reasons we should continue to study the various forms and potential applications of ketone supplements.
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.
I began by simply playing all of the games over and over again (each game many dozens of times over the period of a week) to remove any “learning effect.” I then selected two games from each category (for a total of 10 games) and for a period of five days prior to “ketone-day” played each game five times each day. My “before ketones” baseline scores put me in the top 4% of all Lumosity users, so I was already in a good place. But could I improve even more, just one hour after consuming the ketones?
Long-Term Effects of a Ketogenic Diet in Obese Patients – The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did not produce any significant side effects in the patients. Therefore, the present study confirms that it is safe to use a ketogenic diet for a longer period of time than previously demonstrated.(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716748/)
BHB Salts and exogenous ketone supplements are literally changing the supplement industry. These products are pretty new and a little more expensive than other supplements. But I’d rather pay for something that works then spend tons of money chasing products that claim to work. One of the most popular ketone supplements is Ketōnd. You can check out our review here.
So I’ve been primarily on a Keto diet for almost 6 months. During this time, I have fine tuned a lot to get my ketone levels up (Eating more fat and less protein). Most recently, I have used blood measurements for my ketone levels and I fluctuate between .6 and 2.6. The higher readings I get on the days I workout in the morning (about 5 hours before I draw blood and take a reading). I don’t have any problems sticking to the diet. It only seems to get easier. I’ve also incorporated 16 hour fasts which also are becoming easier over time. My priority and motivation for doing a keto diet is first and foremost weight loss. So far I have lost 40 pounds and I need to lose about 20 more. I do however want to improve my performance (running) and strength (I am doing the Stronglifts 5×5 program now).
These studies were approved by external Research Ethics Committees (London Queen's Square: 14/LO/0288 and South West Frenchay: 15/SW/0244) and were conducted in accordance with the Declaration of Helsinki (2008). Studies took place at the University of Oxford between September 2014 and September 2016. Participants were healthy, aged 21–57, non-smokers and had no history of major illness. Female participants were using oral contraception to minimize the effects of menstrual phase on results. Participants provided written informed consent prior to inclusion, and completed a confidential medical screening questionnaire to determine eligibility. Anthropometric characteristics are shown in Table Table1.1. Sample sizes were chosen following an estimated power calculation based on the effect size in previous work using KE drinks (Clarke et al., 2012b; Shivva et al., 2016).
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...
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!
Effects of ketone supplementation on organ weight: Data is represented as a percentage of organ weight to body weight. a, b, d, f Ketone supplements did not significantly affect the weight of the brain, lungs, kidneys or heart. c Liver weight was significantly increased as compared to body weight in response to administered MCT ketone supplement compared to control at the end of the study (day 29) (p < 0.001). e Rats supplemented with BMS + MCT, MCT, and BD had significantly smaller spleen percentage as compared to controls (p < 0.05, p < 0.001, p < 0.05). Two-Way ANOVA with Tukey’s post-hoc test; results considered significant if p < 0.05. Error bars represent mean (SD)
Ketōnd is an intelligently designed formula containing an industry leading 13,900mg blend of high-powered goBHB™ all packed into a 100% transparent, proprietary blend free formula. Ketōnd is widely known as the most ‘potent’ exogenous ketone supplement available that has been formulated for anyone looking to manage their weight, maximize cognition, or simply feel more energetic in a low carbohydrate environment.
To enter ketosis, up to 80%of your daily calories should come from fat. To put this into a frame of reference, if you eat 2,000 calories a day, 1,600 of those calories should come from fat sources. This comes out to roughly 144-170 grams of fat. Both quantity and quality are equally important, so consume fats from high-quality sources, like omega-3 and omega-6 fatty acids.
Halitosis (bad breath) – If you’re on a ketogenic diet you are probably aware that as the body starts to metabolize fat, ketones can cause poor breath. There is very little one can do about this, it’s just the nature of the beast. Unfortunately, this can also arise when using exogenous ketones, but it’s not as lasting as when on a ketogenic diet. Chewing gum or mints is about the best option if it becomes a noticeable issue. This maybe caused by over consumption of the ketone supplement, tailoring the quantity consumed may prevent excess BHB being converted to acetone, which is likely excreted by the lungs.
Ketone monoester and diester compounds may circumvent the problems associated with inorganic ion consumption in KS drinks. KE ingestion rapidly increased blood ketone concentrations to >5 mM in animals (Desrochers et al., 1995a,b; Clarke et al., 2012a) and the first oral, non-racemic KE for human consumption, (R)-3-hydroxybutyl (R)-3-hydroxybutyrate, raised blood βHB concentrations to 3–5 mM in healthy adults (Clarke et al., 2012b; Shivva et al., 2016) and athletes (Cox et al., 2016; Holdsworth et al., 2017; Vandoorne et al., 2017). However, the pharmacokinetics and pharmacodynamics of this KE with confounding factors, such as prandial state or multiple KE drinks, have not been characterized.
Glucose and BHB went down slightly throughout the effort and RQ fell, implying a high rate of fat oxidation. We can calculate fat oxidation from these data. Energy expenditure (EE), in kcal/min, can be derived from the VO2 and VCO2 data and the Weir equation. For this effort, EE was 14.66 kcal/min; RQ gives us a good representation of how much of the energy used during the exercise bout was derived from FFA vs. glucose—in this case about 87% FFA and 13% glucose. So fat oxidation was approximately 12.7 kcal/min or 1.41 g/min. It’s worth pointing out that “traditional” sports physiology preaches that fat oxidation peaks in a well-trained athlete at about 1 g/min. Clearly this is context limited (i.e., only true, if true at all, in athletes on high carb diets with high RQ). I’ve done several tests on myself to see how high I could push fat oxidation rate. So far my max is about 1.6 g/min. This suggests to me that very elite athletes (which I am not) who are highly fat adapted could approach 2 g/min of fat oxidation. Jeff Volek has done testing on elites and by personal communication he has recorded levels at 1.81 g/min. A very close friend of mine is contemplating a run at the 24 hour world record (cycling). I think it’s likely we’ll be able to get him to 2 g/min of fat oxidation on the correct diet.
