So by taking in the perfect keto base, which are the exogenous ketones (BHB). This will easily put my body into ketosis rather than having to do the ketosis diet? I cant make up my mind on whether to buy the ketone powder and/or the MCT oil powder. What is the benefit of the MCT oil powder? When i read about it on the perfectketo website, it sounds like it does the same job as the perfect keto base. I’m also curious about the bone broths others sell for ketose related stuff. Is it very benedficial even when it has about 600mg of sodium in it?
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.
A common question is why BHB is the go-to ketone body for exogenous ketone supplements. The likely reason is a combination of its efficient conversion into energy and its ease of formulation. In other words, that it is easier to formulate BHB into a nutritional supplement. And the body efficiently converts BHB to acetoacetic acid, which effectively raises blood ketone levels.

Once the body is able to generate energy with the help of exogenous ketones which are present in the bloodstream, it would start looking for other sources of ketones. This would encourage the body to tap into the vast reserve of fat which is accumulated in the body. Thus, the process of ketosis is accelerated when you consume extra exogenous ketones. This also leads to quicker weight loss and the body entering ketosis faster.


You may find a tiny amount here and there is ok (i.e., 2g of sugar with a meal full of fat may be ok).  But if you are starting out I would recommend cutting all sugar from your diet, and most importantly avoiding any sugar consumption on an empty stomach. For best results track your ketone levels before and after meals to see the impact the food has on your ketone levels.

For the ketone esters, on the other hand, repeated doses of 20-30 grams in any one day may be possible. Thus these products may be able to maintain a modest level of ketonemia without dietary carbohydrate restriction. Thus some of the cardiac and brain fueling benefits may follow, not to mention the epigenetic effects limiting oxidative stress and inflammation. But given the recent observation that administered ketone esters markedly reduce circulating free fatty acids (Myette-Cote 2018) — possibly due to an insulin-tropic effect or direct suppression of lipolysis (Taggart 2005) — their sustained use in people with underlying insulin resistance may compromise their long-term benefits by promoting weight gain unless combined with carbohydrate restriction.


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.
Obviously, cutting carbs is much easier than not eating anything at all for days on end. It's also safer for people with diabetes as it leads to a gradual decline in blood glucose [2]. The carbs you have to reduce are known as net carbs. Those are the carbs that your body uses to make glucose. You calculate them by subtracting the grams of fiber from total carbs in a food item.
Participants refrained from alcohol and caffeine for 24 h prior to each visit AND were asked to consume a similar meal the night before each visit. All studies were carried out at the University of Oxford Human Physiology Laboratories and started at 0800 h following an overnight (>8 h) fast, with a minimum of 72 h between visits. Visit order was randomized prior to commencement by an administrative investigator using a pseudo-random number generator to produce a list of combinations of visit order, which were then allocated based on order of enrolment by a different investigator.
The salts typically utilize sodium, potassium, calcium, or magnesium as the cation. Because these cations vary in molecular weight and valence (1+ or 2+), the amount of mineral delivered per gram of BOHB varies from 10% for the magnesium salt to 27% for potassium. Given that recommended daily intakes of these various minerals range from a few hundred milligrams up to 5 grams, whereas the daily ketone intake goal to mimic nutritional ketosis blood levels would need to be on the order of 50 grams, achieving this goal with ketone salts would severely challenge human dietary mineral tolerance.
Ketone Salts: While the body uses and makes BHB ketones salts naturally, in supplement form ketone salts are synthetically (lab) made compounds that combine sodium (and/or potassium, calcium, or magnesium) with BHB. The salt is used to raise the pH and make things less acidic. Currently, all ketone supplements on the market are made from ketone salts. While they raise ketone levels, most people will only experience mild nutritional ketosis (~0.6-1.0 mmol/L).
There are many top-rated exogenous ketone supplements, which is a great resource to help get your body to adapt faster and produce at a high-performance level, but you need to be careful how they can effect you and your energy levels and your general mood each day, so it’s important to check with your local physician and be safe about it. Remember that when you switch over to this diet, you must maintain high sodium levels during the process. It is recommended to add more 'keto salt' to your daily intake, starting off gradually and increasing it to as much as 500g a day. You need to add salt and electrolytes to your routine, because a person can lose levels through their urine, which causes your body to become more dehydrated and can leave you feeling a little sick and weak if you don't have the balance properly set up. Most exogenous ketone supplements we found have quite a bit of sodium in their ingredients, which helps you reach the level of salt intake you need each day. It is important to understand how this whole process works before even thinking about tackling it yourself. This is why you should consult with a professional to seek out advice and address any concerns that you may have before getting started.

There is a great deal of positive speculation that exogenous ketones can be beneficial for inflammation, cognitive enhancement, and even protection against certain types of cancer. There is mounting evidence that the ketogenic way of eating can help many people, and when used appropriately with realistic expectations, exogenous ketone supplementation can enhance these positive effects (25).
You may wonder why we are emphasizing on using these specific oils. Well, this is because the extra virgin oil is an unprocessed form, and contains lauric acid that is antimicrobial in nature and is good for brain health. (This is the same lauric acid that is naturally found in breast milk as well.) Its antibacterial property also indirectly supports the growth of Candida that keep your gut healthy.

There is so much talk about the benefits of a ketogenic diet and its ability to improve fat burning, brain health, energy and anti-aging.  The main units of energy on a ketogenic diet are ketone bodies, of which beta hydroxybutyrate (BHB) is the main player!  This article will go over the health benefits of BHB and exogenous ketones. Additionally, this article will cover strategies on using exogenous ketones in your daily life.
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.

I bought this because I didn't want to be sucked into an autoshipment for a ketone supplement like KetoOS, which is HOT right now. I did the comparison on the ingredient list between this product and KetoOS and they are quite similar. I think one of the big differences is that KetoOS has the option of caffeinated or non-caffeinated powders. For the cost and the free shipping (I'm a Prime member), it's something I could easily fit into my budget, rather than the $114 canister you'd get with KetoOS.
Will taking exogenous slow down my fat loss? Since now before digging into my body for energy/ketones, I will first use up the exogenous ketones I ingest. Also do exogenous ketones somehow help get even more keto adapted, keeping in mind I have been on a strict keto diet without a problem and don’t mind it at all. Outside of performance improvements, do you think exogenous ketones is for someone like me who is primarily looking for fat loss.
Exogenous ketones are powerful. They will get you into ketosis whether keto-adapted or not. The benefits of this range from weight loss to sustained mental and physical energy. The benefits are the same as those from nutritional ketosis, however, they’re not a substitute for nutritional ketosis. More on that below before we get into the top 5 exogenous ketones for 2018.

Besides cutting carbs, it's important to increase your fat intake, and be moderate with protein. The fat you eat will keep you feeling energized and support ketone production. Protein is also important but if you go overboard with it, your body could enter into a process called gluconeogenesis. In gluconeogenesis, your body makes glucose from protein, and you want to avoid that.
Even Ben Greenfield Has Thyroid Problems While In Ketosis - “Ben describes one of the main side effects that he encountered being severe hypothyroidism… manifesting as severe sensitivity to cold, poor libido, and poor overall energy. The way they treated this was to eat a lot of liver, desiccated thyroid, and sweetbreads which seemed to fix things for him.”
When your body is done using up a certain substrate to create energy (acetyl-CoA) after eating carbohydrates, it will start to find creative ways to get the job done. This is something that you want to happen. This is the switch to ketosis. If you didn’t do this, you’d be dead after fasting for a very short period of time. Under normal circumstances, the liver will start making beta-hydroxybutyrate from long chain and medium chain fatty acids that are liberated from your fat tissue. You are turning fat into fuel. Good work. This is why people can fast for months at a time and still function like normal humans.
I feel like I should also mention that the GI discomfort is real, people. I would recommend starting this product on a weekend or a day where you’re able to just take it easy. After my first dose, which was only 1/2 scoop, I literally just felt like lying in bed all day due to feelings of nauseousness; however, by the next day I was fine and even bumped my dose to a full scoop.

Meanwhile Brinkworth, et al., in their 2009 paper "Long-term Effects of a Very Low-Carbohydrate Diet and a Low-Fat Diet on Mood and Cognitive Function" looked at the effects on ketogenic diet on cognitive function and mood. The study participants ate a ketogenic diet for a year and the researchers found that mood levels decreased when compared to a group eating a high carb/low fat diet. They go on to remark “there was no evidence that the dietary macronutrient composition of LC and LF diets affected cognitive functioning over the long term, as changes in cognitive function were similar for both diets”.
Dominic D’Agostino has two in-depth interviews on The Tim Ferriss Show (Part 1, Part 2). Discussion includes exogenous ketones for mitigating the onset of neurodegenerative diseases, using ketones in place of fasting for chemo-protection, benefits of ketone supplementation when consuming carbohydrates, the risks and potential toxicities of ketones.
Studies show that exercising depletes both liver and muscle glycogen faster than fasting [4]. For example, swimming for an hour and a half depletes the same amount of glycogen as a 24-hour fast. However, it's a good idea to eat a tiny amount of carbs and protein before and after a workout to prevent muscle damage. Your body can break down proteins in your muscles if glycogen stores get depleted during workouts.

Now onto the best ketone supplements. All of these 5 are great products with good customer experiences and reviews. The list contains 3 MCT oil powders and 2 BHB salts. Since it’s just 5 products, there’s no room for bad quality. If you see a lower rating it may be due to price/value, the taste or perhaps a lack of third-party inspection certificates.
If the color is close to the original beige of the test strip, it means there are few if any ketones in your urine and you’ll need to make some dietary tweaks. This may include eating less fat. That’s because if you have doubled down on the healthy fats your body may be rebelling. One way to tell is if you are constipated. If you think this is the case, ratchet back the fats by 50% and see if it makes a difference.

Human's ability to produce and oxidize ketone bodies arguably evolved to enhance survival during starvation by providing an energy source for the brain and slowing the breakdown of carbohydrate and protein stores (Owen et al., 1967; Sato et al., 1995; Marshall, 2010). The brain is normally reliant on carbohydrate as a substrate, being less able to metabolize lipids, despite adipose tissue representing a far larger energy store than muscle and liver glycogen. Therefore, during starvation, lipids are used for hepatic ketogenesis and, via ketone bodies, lipids sustain the brain. Endogenous production of the ketone bodies, d-β-hydroxybutyrate (βHB) and acetoacetate (AcAc), increases slowly, driven by interactions between macronutrient availability (i.e., low glucose and high free fatty acids) and hormonal signaling (i.e., low insulin, high glucagon and cortisol). Produced continuously under physiological conditions, blood ketone concentrations increase during starvation (Cahill, 1970), when consuming a “ketogenic” (low carbohydrate, high-fat) diet (Gilbert et al., 2000) or following prolonged exercise (Koeslag et al., 1980).
Whereas ketone esters are 100% D- form, most ketone salts are a 50/50 mix of left and right-handed beta hydroxybutyrate, which is known as a racemic mixture. These beta hydroxybutyrate molecules are linked to a mineral, such sodium (Na), calcium (Ca), potassium (K), or magnesium (Mg). This kind of ketone supplement gets broken down to left and right-handed version of beta hydroxybutyrate along with the mineral.
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.
Exogenous ketones can lower appetite during a fast. After an overnight fast, normal weight human subjects either drank a ketone ester supplement or a calorie-matched glucose drink. Compared to the glucose drinkers, the ketone drinkers had lower insulin, lower ghrelin, greater satiety, and less hunger. This can be useful for people trying to extend their fast who don’t want to or can’t yet deal with the hunger. You’re still taking in energy, but the metabolic profile remains similar to that of a fasted person.
I’ve tried this, got a few bags of one ketone salts bound to mostly potassium and another one bound to calcium. As for working out, I find that consuming 15-20 grams of glucose ( dextrose ) 30 minutes before either a HIIT or a heavy lifting session gives me a much, much bigger boost than ketones. so they just sit in my cupboard. I also got spooked about the amount of potassium i’d consume in one go ( don’t particularly fancy a cardiac arrest ). I find it a bit useful when I have a big meeting or something else that requires super concentration and I’m fasting, other than that – it’s pretty useless. I’d probably use more of it if I could find a formula that’s mostly sodium/magnesium based rather than potassium and/or calcium.
I simply use this to attempt to reduce the symptoms of the "keto-flu" when I'm entering ketosis after blowing my carbs out. The holidays are particularly bad for falling off the keto band-wagon. I've used this three times now to transition back into ketosis and I can report that it does seem to reduce the effects of the keto flu (headache, weakness) that I'd normally experience transitioning back into a low-carbohydrate diet. I typically take it for 3 days and then stop because by that time I'm in ketosis again, but I'd imagine you could take it longer.
