Your body uses the energy source that is the easiest to use, in our case this is glucose. Glucose is just a type of sugar. As our body cannot store glucose as such it stores the extra glucose in form of glycogen that is stored in our liver and muscles. To initiate production of ketones in your body as fast as possible you must deplete your body of glycogen reserves. The best way to do this is a simple 24 hours fast. This will deplete your glycogen stores as fast as possible. If you don’t over eat for dinner or you even skip it all together you will already wake up in state of mild ketosis the next morning due to the overnight fast. Here are also described some signs that you are in Ketosis already.
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:

If you’re somebody who isn’t already a keto-goer, then you might be wondering why? Why do I need to limit my carbohydrate intake to get my body into a state of ketosis? Simply put, and without getting to technical; you want your body to be in a constant state where fat is the is the primary source of fuel for the body rather than glucose. You see, once you eat carbs, the body will break this down into glucose which it will then use for fuel before tapping into your fat reserves for energy. If you limit the amount of glucose that is in your system by restricting your carbohydrate intake, the body has no choice but to tap into your fat stores for energy. Fats are metabolised in the liver where ketones are then produced for your physical and cognitive needs.

As stated above, there appears to be a difference between supplemental and dietary calcium intake, which can be important to keep in mind.  One study found aggregate calcium intakes above 1400 mg per day (from dietary and supplemental intake combined) to be associated with higher death rates, cardiovascular disease, and ischemic heart disease in women[15]. A 2014 meta-analysis found an association between dietary calcium intake and cardiovascular mortality[16]. The meta-analysis actually found a u-shaped relationship, where dietary calcium intakes that were both lower and greater than 800 mg/day were gradually associated with increased risk of cardiovascular mortality.
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.
The difference in peak blood d-βHB concentrations between matched amounts of βHB as ester or salts arose because the salt contained l-βHB, as the blood concentrations of d- plus l-βHB isoforms were similar for both compounds. It is unclear if kinetic parameters of KE and KS drinks would be similar if matched d-βHB were taken in the drinks. Unlike d-βHB, blood l-βHB remained elevated for at least 8 h following the drink, suggesting an overall lower rate of metabolism of l-βHB as urinary elimination of l-βHB was in proportion to plasma concentration. Despite similar concentrations of total βHB, breath acetone was ~50% lower following KS drinks compared to KE, suggesting fundamental differences in the metabolic fates of D- and L-βHB. These findings support both previous hypotheses (Veech and King, 2016) and experimental work in rats (Webber and Edmond, 1977), which suggested that the l-isoform was less readily oxidized than the d-isoform, and is processed via different pathways, perhaps in different cellular compartments. It seems that l-βHB is not a major oxidative fuel at rest, and may accumulate with repeated KS drinks. However, the putative signaling role of l-βHB in humans remains unclear. In rodent cardiomyocytes, l-βHB acts as a signal that modulates the metabolism of d-βHB and glucose, Tsai et al. (2006) although no differences in blood glucose were seen here. Furthermore, L-βHB can act as a cellular antioxidant, although to a lesser extent than D-βHB (Haces et al., 2008).

Ketone supplementation did not affect the size of the brain, lungs, kidneys or heart of rats. As previously mentioned, the rats were still growing during the experimental time frame; therefore, organ weights were normalized to body weight to determine if organ weight changed independently to growth. There could be several reasons why ketones influenced liver and spleen weight. The ratio of liver to body weight was significantly higher in the MCT supplemented animals (Fig. 5). MCTs are readily absorbed in the intestinal lumen and transported directly to the liver via hepatic portal circulation. When given a large bolus, such as in this study, the amount of MCTs in the liver will likely exceed the β-oxidation rate, causing the MCTs to be deposited in the liver as fat droplets [94]. The accumulated MCT droplets in the liver could explain the higher liver weight to body weight percentage observed with MCT supplemented rats. Future toxicology and histological studies will be needed to determine the cause of the observed hepatomegaly. It should be emphasized that the dose in this study is not optimized in humans. We speculate that an optimized human dose would be lower and may not cause hepatomegaly or potential fat accumulation. Nutritional ketosis achieved with the KD has been shown to decrease inflammatory markers such as TNF-α, IL-6, IL-8, MCP-1, E-selectin, I-CAM, and PAI-1 [8, 46], which may account for the observed decrease in spleen weight. As previously mentioned, Veech and colleagues demonstrated that exogenous supplementation of 5 mM βHB resulted in a 28 % increase in hydraulic work in the working perfused rat heart and a significant decrease in oxygen consumption [28, 41, 42]. Ketone bodies have been shown to increase cerebral blood flow and perfusion [95]. Also, ketone bodies have been shown to increase ATP synthesis and enhance the efficiency of ATP production [14, 28, 40]. It is possible that sustained ketosis results in enhanced cardiac efficiency and O2 consumption. Even though the size of the heart did not change for any of the ketone supplements, further analysis of tissues harvested from the ketone-supplemented rats will be needed to determine any morphological changes and to understand changes in organ size. It should be noted that the Harlan standard rodent chow 2018 is nutritionally complete and formulated with high-quality ingredients to optimize gestation, lactation, growth, and overall health of the animals. The same cannot be said for the standard American diet (SAD). Therefore, we plan to investigate the effects of ketone supplements administered with the SAD to determine if similar effects will be seen when the micronutrient deficiencies and macronutrient profile mimics what most Americans consume.
Ketōnd discloses everything right there on their label so you know EXACTLY what you are getting. I have tried numerous ketone supplements and I can tell you I was not surprised that Ketōnd gave me more energy, mental clarity and improved my training more than any other ketone supplement. But take a few minutes and look at the product comparisons. You will see that Ketōnd has more ketones per serving and comes in at a fraction of the cost of every other product out there.

Animal research findings report that BHB supplementation also enhances oxygen utilization, especially in the central nervous system (CNS).[11] While molecular oxygen is a crucial molecule for health and longevity, too much of it can be potentially toxic and speed the effects of aging in tissues throughout the body.Therefore, using a BHB supplement can effectively mitigate the toxic buildup of molecular oxygen, particularly in the CNS/brain.
To be in ketosis, you need to get very specific about the macronutrient ratios hanging off your fork. This means eating 75% fats, 20% protein and 5% carbohydrates. It’ll see you getting 5-10% of your total calories from carbohydrates, which is roughly 25-30g of carbs per day, and diligently keeping this below the 50g threshold creates the ketosis that burns stored fat. Unlike the no-limit-protein option on the table when going low carb, eating more than 0.67-0.81g of protein per pound of bodyweight can hoof you out of ketosis because too much of it can be converted into glucose, blunting the benefits of the ketones. On the plus side, you will have a high fat intake, making your energy levels more balanced so you can train at higher intensities.
I got the Peaches and Cream flavor of Perfect Keto and it's good; a nice sweet break from all the meat, cheese, and vegetables. I would recommend that you use cold water and a shaker bottle though. It takes a bit of vigorous shaking to get the lumps to melt, but it does melt seamlessly. It has a peach taste, but more like a peach with a bitter aftertaste, which I guess is expected with any ketone supplement. I read that a lot of the available supplements taste awful and this one doesn't taste awful. But don't go into it expecting it to taste like a peach pie. :-) I know some of the other supplements say to mix with a keto beverage; I've seen half and half and heavy cream as mixers because the carbs are low and fat high. I haven't tried that as I am only taking in 1,200 calories per day.
And now, you can take ketone supplements (salts and esters), known as exogenous ketones, without actually restricting anything. According to those promoting this nasty-tasting supplement, that means you can have a brain and body fuelled by ketones, along with all of the supposed health benefits that come with running on fat. Well, don't fall for it.
Most people confuse thirst for hunger, and it's crucial to not make that mistake when you're dieting. Try to drink water first before heading to the fridge to get some snacks--you might realize that you're not really hungry at all and you are, in fact, only thirsty. Training yourself to spot the difference between hunger and thirst will help you induce ketosis faster. 

It’s sometimes the case that a person has been attempting to transition to a state of ketosis, but in spite of their best efforts, they seem stuck in a kind of limbo where they’re eating hardly any carbs, but they don’t seem to be losing weight or experiencing the other benefits of the keto diet. But the science is the science, which means if you’re doing everything right you should be in ketosis. If you’re not, or you seem to be drifting in and out of a keto state, it’s not your body’s fault, it’s your diet.


It might sound absolutely crazy to go that long without food. Especially when you consider traditional diets that recommend eating 3-5 small meals each day, starting with breakfast – the “most important” meal of the day. But if you think back to hunter gatherer times, human beings didn’t always have food accessible to us. Farming and agriculture hadn’t existed so our first meal each day would vary quite vastly. If you think about the word itself, ‘breakfast’ means to break-fast. We didn’t have a set time where we would consume our first meal – it was dependent on accessibility. So if you’re wondering how you’re going to survive without going for food for 16 hours, the answer is straight forward – you can! Let’s simplify this and break down what this may potentially look like.
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?

Price: The supplements are expensive – very expensive. At the top end, if you follow Prüvit’s guidelines on “getting in the n8tive zone” (which is such a gimmicky marketing slogan it almost makes me cringe), you will require 2 servings of their Keto-OS product per day. This means around 60 servings per month, which will set you back a whopping $390 per month if you buy direct from their website! In the case of Prüvit, this is in part due to the multi-level marketing structure they operate under.
Perfect Keto Base BHB Salt has everything you need in a BHB salt and nothing you don’t. For this reason, it shares the number one spot alongside their MCT oil powder as the best exogenous ketone supplements you can find. As far as price and value, many other BHB salts are more expensive, and lesser quality as they use additives and fillers. What gives Perfect Keto Base their edge outside of their proven raw ingredients quality is, taste. BHB salts are hard to make palatable. Perfect Keto has risen above when it comes to taste as well.
Before the Nobel Prize was awarded to Yoshinori Ohsumi, other researchers were making groundbreaking discoveries about autophagy. In 2009, an article was published in Cell Metabolism entitled Autophagy Is Required to Maintain Muscle Mass. In this article, researchers described how deactivating an important autophagy gene resulted in a profound loss in muscle mass and strength.

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.
Exogenous ketones are also for those just looking to try it out. It lets anyone be able to access ketones simply by consuming these exogenous forms of ketones. Technically, MCTs are not an exogenous ketone such as BHB salts. They’re not ketones. But they readily convert into ketones. So MCT oils and powders are a great source of endogenous ketones. The end result is similar, and thus this top 5 list includes MCT oil powders as well as BHB salts.
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/)

Nutritional ketosis induced with the KD has proven effective for the metabolic management of seizures and potentially other disorders [1–26]. Here we present evidence that chronic administration of ketone supplements can induce a state of nutritional ketosis without the need for dietary carbohydrate restriction and with little or no effect on lipid biomarkers. The notion that we can produce the therapeutic effects of the KD with exogenous ketone supplementation is supported by our previous study which demonstrated that acutely administered KE supplementation delays central nervous system (CNS) oxygen toxicity seizures without the need for dietary restriction [29]. We propose that exogenous ketone supplementation could provide an alternative method of attaining the therapeutic benefits of nutritional ketosis, and as a means to further augment the therapeutic potential of the KD.

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.


Also known as the carb flu, the keto flu is commonly experienced by people who are transitioning to a Ketogenic diet. “Keto flu” is not actually flu but mimics the experience of flu with very similar symptoms. It can happen when someone who has become accustomed to relying primarily on carbohydrates as fuel removes them from their diet. Whilst this is a necessary step towards adjusting from being a sugar-burner to a fat-burner, the sudden change can trigger some unpleasant symptoms, much like withdrawing from an addictive substance. Keto flu symptoms can include drowsiness, nausea, dizziness, achy muscles, mental fogginess and an irritable mood. The good news though, is that most of these experiences relate to dehydration and electrolyte depletion, and so are easily prevented or managed. Simply adding a ¼ - ½ teaspoon of a high quality sea salt or sodium/potassium powder to a glass of water works wonders; however you may still require a separate magnesium supplement; particularly if you are prone to muscle cramps or restless legs. Another popular way to manage your electrolytes is via a good quality bone broth powder. Finally, since BHB’s are normally delivered via a mineral salt base*, keto flu symptoms are easily prevented or reduced by using an exogenous ketone supplement powder.

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.

Hi, I still a little confused about when or how to take this. I am trying to get adapted and minimize the flu. Is it most beneficial before eating, after eating, with food or in place of food? I have been keto in the past but this time I am not switching over to fat burning mode even though my macros are good. ( I am thinking it is just too many calories and carbs at this point but I get hungry!) Help please.


Selective attention involves focusing only on relevant information while suppressing the impulse to pay attention to irrelevant distractions. A v-shaped flock of birds are displayed. The center (target) bird points in one direction and is surrounded by birds that either match the target’s direction or do not. The task is to rapidly identify which direction the target bird is pointing.

The classical KD consists of a 4:1 ratio of fat to protein and carbohydrate, with 80–90 % of total calories derived from fat [27]. The macronutrient ratio of the KD induces a metabolic shift towards fatty acid oxidation and hepatic ketogenesis, elevating the ketone bodies acetoacetate (AcAc) and β-hydroxybutyrate (βHB) in the blood. Acetone, generated by decarboxylation of AcAc, has been shown to have anticonvulsant properties [28–32]. Ketone bodies are naturally elevated to serve as alternative metabolic substrates for extra-hepatic tissues during the prolonged reduction of glucose availability, suppression of insulin, and depletion of liver glycogen, such as occurs during starvation, fasting, vigorous exercise, calorie restriction, or the KD. Although the KD has clear therapeutic potential, several factors limit the efficacy and utility of this metabolic therapy for widespread clinical use. Patient compliance to the KD can be low due to the severe dietary restriction - the diet being generally perceived as unpalatable - and intolerance to high-fat ingestion. Maintaining ketosis can be difficult as consumption of even a small quantity of carbohydrates or excess protein can rapidly inhibit ketogenesis [33, 34]. Furthermore, enhanced ketone body production and tissue utilization by the tissues can take several weeks (keto-adaptation), and patients may experience mild hypoglycemic symptoms during this transitional period [35].
I have Type 2 Diabetes. I have bought a product that has Beta Hydroxybutyrate in it. Is it dangerous for me to take it whereas I am a Type 2 diabetic. Can it cause me to go into Diabetic ketoacidosis which is very dangerous for a diabetic even deadly. I have been trying to find an answer to my question and your sight seems to have the best insight on Beta Hydroxybutyrate . I bought the product without knowing it had Beta Hydroxybutyrate in it and have not tried it out of fear that it will cause me to go into Diabetic ketoacidosis. Other people I know have taken it and lost weight and I really want to take it but I am afraid. Just so you know it is on a patch with other elements in it. Please help me I look forward to your answer

Yes — you read that correctly — 24 hours of intermittent fasting without any resistance training and these subjects were able to preserve more muscle mass than the subjects that ate fewer calories every day without fasting at all. This finding contradicts our common sense, but when we dig deeper into autophagy we can find the mechanism behind this result.


Most of the ketone supplements out there are either underdosed or overpriced - some don't even bother to disclose how much BHB (ie ketones) is used in their product. And why would they? BHB is EXTREMELY expensive. So by not disclosing the amount the can get away with putting in as little as they want and still claim it's a ketone supplement while keeping their costs as low as possible.

Exogenous ketones have a wide range of benefits that can enhance your fat-burning lifestyle. I personally use them daily as a strategy to heighten my mental performance and give my workouts an extra boost. For these purposes, I have also found it logical to combine exogenous ketones with other known health and performance boosting agents such as branched-chain amino acids and medicinal mushrooms.
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.
There’s some support that exogenous ketones can be helpful for people already dutifully following the keto diet — but research has been limited. One thing we know for sure: These aren’t a get-thin-quick solution. “I think people are drawn to a quick, easy fix, kind of a magic bullet supplement, and it’s not that this won’t contribute to weight loss, but it’s not that magic bullet,” Griffin says.
The two compounds commonly referred to as ‘ketone bodies’ (BOHB and AcAc) are produced and used for multiple purposes across nature from algae to mammals, but seldom in concentrations useful for extraction as human food. For this reason, the source of most exogenous ketones is chemical synthesis. Furthermore, most current research and use of ketone supplements focuses on BOHB. That is because AcAc is chemically unstable – it slowly breaks down to form acetone by releasing of one molecule of CO2.
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.

We will go deep in the science behind this fascinating diet and then review some of the best exogenous ketone supplements out there in the market. Because without the knowledge and the right information about exogenous ketones that you can properly follow, you might never reach your goals and you may as well keep eating that mashed potato for dinner and club sandwich for lunch.
Firstly, in a randomized four-arm cross-over study, blood βHB concentrations were compared following ingestion of equal amounts of βHB as a KE or a KS at two doses by healthy volunteers at rest (Study 1; n = 15). Secondly, in a randomized five-arm cross-over study, inter- and intra-participant repeatability of ketosis was examined following ingestion of identical KE drinks, twice whilst fed and twice whilst fasted. As a control, participants also consumed one isocaloric (1.9 kCal.kg−1) dextrose drink (Study 2; n = 16). Finally, blood d-βHB was measured after equal amounts of KE were given as three drinks (n = 12) or a constant nasogastric (NG) infusion (n = 4) (Study 3; total n = 14) over 9 h.
This research is a good reminder to discuss with your doctor before taking any supplements. Given the widespread use of calcium supplements, more research is required before any final conclusions can be drawn. Several ketone companies have tried to avoid the large sodium loads but instead relied on a bump in the calcium content from the BHB ketone salts, seemingly without consideration for the aforementioned results. Calcium BHB will likely absorb slower compared to sodium BHB due to digestion and absorption kinetics.  For those looking to optimize brain uptake of ketones, this probably isn’t the best strategy (as uptake is directly proportional to the levels in the blood).   Be cautious of supplements running from the sodium and chasing the calcium BHB instead, and make sure you factor that into your overall daily needs.
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.
The body will start making ketones when either we go extended periods without food, or we restrict the one dietary component that stops ketone formation – this being carbohydrates and also minimising protein intake as this also can halt ketone. In turn, your primary source of food is fat, with very little carbohydrate and a small amount of protein.”
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.)

Individuals who have clinically unregulated blood sugar, such as those with diabetes, are cautioned to consult their trusted healthcare provider before choosing to use exogenous ketones. While it can be done safely, especially in the presence of a well-formulated ketogenic food plan, there may be a risk of blood sugar dropping unexpectedly low. There may be therapeutic value in this application, but close monitoring is key.


There is also evidence that individuals who adhere to a low-carbohydrate or ketogenic diet may require higher sodium intakes. Due to their low carbohydrate contents, these diets reduce insulin levels. Since one of insulin’s roles is to decrease the excretion of sodium in the urine[7], low-carbohydrate and ketogenic dieters excrete more sodium than normal, and are encouraged to salt their meals to increase their sodium intake.
Lastly, EK products in general ​are usually in the form of salts, which is why they are referred to as BHB Salts. The BHB ketones are bound to common salts such as sodium​, calcium, magnesium and potassium​ to improve absorption rate. These salts are also the core electrolytes your body needs to help you avoid feeling mentally drained and physically lousy during the keto-flu transition period.
Calories do matter, even on a ketogenic diet. If you consume more calories than your body uses, you’re going to gain weight. Period. What you mean to say is that it’s very difficult to eat your entire day’s worth of calories on a ketogenic diet because fats are so satiating. This distinction is important to keep in mind for those who generally have a voracious appetite (like me).
Intermittent fasting is using the same reasoning – instead of using the fats we are eating to gain energy, we are using our stored fat. That being said, you might think it’s great – you can just fast and lose more weight. You have to take into account that later on, you will need to eat extra fat in order to hit your daily macros (the most important thing). If you’re overeating on fats here, you will store the excess.

It might sound absolutely crazy to go that long without food. Especially when you consider traditional diets that recommend eating 3-5 small meals each day, starting with breakfast – the “most important” meal of the day. But if you think back to hunter gatherer times, human beings didn’t always have food accessible to us. Farming and agriculture hadn’t existed so our first meal each day would vary quite vastly. If you think about the word itself, ‘breakfast’ means to break-fast. We didn’t have a set time where we would consume our first meal – it was dependent on accessibility. So if you’re wondering how you’re going to survive without going for food for 16 hours, the answer is straight forward – you can! Let’s simplify this and break down what this may potentially look like.

To be in ketosis, you need to get very specific about the macronutrient ratios hanging off your fork. This means eating 75% fats, 20% protein and 5% carbohydrates. It’ll see you getting 5-10% of your total calories from carbohydrates, which is roughly 25-30g of carbs per day, and diligently keeping this below the 50g threshold creates the ketosis that burns stored fat. Unlike the no-limit-protein option on the table when going low carb, eating more than 0.67-0.81g of protein per pound of bodyweight can hoof you out of ketosis because too much of it can be converted into glucose, blunting the benefits of the ketones. On the plus side, you will have a high fat intake, making your energy levels more balanced so you can train at higher intensities.


This process can be used as a way to get you into ketosis more quickly, so you can transition gracefully into a ketogenic lifestyle or as a way to stimulate autophagy and fat loss. If you can’t go without fat for the full 3 day fast — it’s okay — you will still illicit many of the benefits of fasting by limiting your protein and carbohydrate intake.
In the second of these posts I discuss the Delta G implications of the body using ketones (specifically, beta-hydroxybutyrate, or BHB, and acetoacetate, or AcAc) for ATP generation, instead of glucose and free fatty acid (FFA). At the time I wrote that post I was particularly (read: personally) interested in the Delta G arbitrage. Stated simply, per unit of carbon, utilization of BHB offers more ATP for the same amount of oxygen consumption (as corollary, generation of the same amount of ATP requires less oxygen consumption, when compared to glucose or FFA).
