Exogenous ketones are not a magical fat-loss supplement, and to suggest otherwise is both factually incorrect and deliberately misleading. In fact, consuming ketones to excess can hinder rather than help fat loss! Aggressive marketing of exogenous BHB’s has helped to create a myth being believed now by millions – that simply drinking ketones each day will somehow magically melt away the pounds. The metabolic fact that unscrupulous marketers do not point out is that dietary fat (plate fat; or fat/ketones you ingest) will be burned before stored fat (body fat). So, whilst exogenous ketones can help you to mitigate hunger (and therefore help you achieve a caloric deficit) – and although they also have many other benefits (detailed below); they are not a magic wand that you can wave to achieve weight or fat loss and should not be marketed as such.

Even though endurance athletes can train in a carb depleted state, they will generally consume carbohydrates in the lead up to a race (the athlete is seeking to increase the ability to run off fats by training in a carb depleted state, then benefiting from both fats AND carbs come race day). Likewise, with the brain, even though the brain can function off ketones, does it mean it’s the best state for brain function?
After a minimal amount of internet "research," I decided to try my first exogenous ketones. I have used the ketogenic diet off and on for at 15 years and my body is pretty efficient at fat adapting. (Usually by the end of 2 strict days, I am in ketosis, but not without symptoms and intense cravings.) I can consistently fast from carbs for 20 - 24 hours and do this consistently. However, around hour 20, my mind begins to negotiate that intermittent fasting is advantageous too and that I can afford to have some carbs once a day. Hence the yo-yo effect.
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
Pruvit v Perfect Keto: One of the more popular brands for BHB salts is Pruvit (Keto OS). Pruvit is a good brand, but they do use some additives. Also, Pruvit is an MLM company that has tons of people pushing their products as the best weight loss product in the world. And you have to use one of their representatives’ referral codes to buy it. Learn more about the two in this Pruvit vs Perfect Keto comparison article.
The USDA guidelines recommend less than 2400 mg of sodium per day for healthy adults, and 1500 mg or less for individuals over the age of 50 or at risk for hypertension[2]. For reference, 2300 mg of sodium is the equivalent of about one teaspoon of salt.  Even though these recommendations are promoted by the American Heart Associated and other health-related organizations, recent research has claimed that there is simply not enough evidence to support these guidelines[5]. Worldwide 24-hour urinary sodium excretion data suggest that the normal range is actually 2500-5000 mg per day, which is what most of us consume daily[6]. Additionally, people with high activity levels or chronically low blood pressure may require more sodium than the average person.
Two ground-breaking studies have recently been published on the effects of intermittent fasting on males. One group of researchers studied the effects that 16 hours of intermittent fasting had on males that lift weights. They found that muscle mass stayed the same, fat mass decreased significantly, and the males who fasted for 16 hours a day burned more fat for fuel compared to the control group that only fasted for 12 hours.
From my personal experience, there are plenty of ketogenic supplements that certainly do work, but you do have to be careful of the "phonies." You can find highly recommended ketones products that are endorsed by celebrity life coaches such as Timothy Ferris and Joe Rogan; then you also have those infomercial products that are probably as effective as eating Tic Tacs, which is why it is really important to do your research before experimenting. Once you are finished scouring this website full of its information, you should be well-equipped to make a calculated decision on whether this whole thing is for you and that means our mission is complete.

When choosing an exogenous ketone supplement, make sure to read the ingredients carefully. Brands that have a “proprietary blend” don’t allow you to see the quantities of each ingredient in their mix. You should know every detail about the supplements you choose, so you know exactly what is affecting your body, and you have control over the variables of your intake.

Patrick Arnold is an organic chemist who is notorious for being the creator of several performance-enhancing steroids. He is arguably one of the strongest influencers on the advancement of sports supplementation. Currently he is focused on developing products under the KetoSports brand, which includes two exogenous ketone products – KetoForce and KetoCaNa.


I have tried the following preparations of exogenous ketones: BHB monoester, AcAc di-ester, BHB mineral salt (BHB combined with Na+, K+, and Ca2+). I have consumed these at different concentrations and in combination with different mixing agents, including MCT oil, pure caprylic acid (C8), branch-chained amino acids, and lemon juice (to lower the pH). I won’t go into the details of each, though, for the sake of time.
