An interview with University of Florida researcher and scientist Dominic D’ Agostino. In that episode, “A Deep Dive Into Ketosis: How Navy Seals, Extreme Athletes & Busy Executives Can Enhance Physical and Mental Performance With The Secret Weapon of Ketone Fuel“, Dominic highlights his research into the use of ketones to enhance breathhold time and reduce the brain’s requirements for oxygen.

Some clinicians[37] regard eliminating carbohydrates as unhealthy and dangerous.[38] However, it is not necessary to eliminate carbohydrates from the diet completely to achieve ketosis. Other clinicians regard ketosis as a safe biochemical process that occurs during the fat-burning state.[35] Ketosis, which is accompanied by gluconeogenesis (the creation of glucose de novo from pyruvate), is the specific state that concerns some clinicians. However, it is unlikely for a normally functioning person to reach life-threatening levels of ketosis, defined as serum beta-hydroxybutyrate (B-OHB) levels above 15 millimolar (mM) compared to ketogenic diets among non diabetics, which "rarely run serum B-OHB levels above 3 mM."[39] This is avoided with proper basal secretion of pancreatic insulin. People who are unable to secrete basal insulin, such as type 1 diabetics and long-term type II diabetics, are liable to enter an unsafe level of ketosis, eventually resulting in a coma that requires emergency medical treatment.[citation needed] The anti-ketosis conclusions have been challenged by a number of doctors and advocates of low-carbohydrate diets, who dispute assertions that the body has a preference for glucose and that there are dangers associated with ketosis.[40][41]
The ketogenic diet: The ketogenic diet could affect cancer by a similar mechanism to calorie restriction and fasting. Of the 29 animal studies that have examined ketogenic diet and cancer, 72% of them have demonstrated an anti tumor effect. There have been a small number of case studies of the safety and efficacy of the ketogenic diet in humans. The results have been largely positive, for example following a ketogenic diet helped to stabilise tumour growth and alter tumor metabolism96 ,97 ,98. There is an absence of fully randomised clinical trials in humans, but 24 case studies have been published; one recent appraisal of the case study data said that “ a probabilistic argument shows that the available data strengthen the belief in the anti-tumor effect hypothesis (of the ketogenic diet) at least for some individuals"99. 
Ken, not 100% sure I understand your question but if you're asking if you should take any more supplements through out the week, it's hard to know without getting some blood testing done. If you want to go into detail, book a consult at bengreenfieldfitness.com/coaching and choose 20 or 60 mins and we'll get you scheduled. If you want to know specifically about fueling for your runs, have a read through this: https://bengreenfieldfitness.com/2013/07/what-…

I originally started this “diet” because I am the Maid of Honor in my best friends wedding. She made me order a size down than I was comfortable with and it fit, if you didn’t zip it up. I tried it on a couple weeks later and it REALLY didn’t fit, I couldn’t pull it up past my hips. I was mortified and super embarrassed, how was I going to be in this wedding if I can’t even fit in this dress. Cut to now, I just tried on my dress and it’s too big! I’m so excited that I have to get it altered.

Similar to the BHB salts and MCT’s from the KETO//OS I discuss above, powdered forms of ketones are excellent if you don’t want to completely eliminate carbohydrates or protein (which can be gluconeogenic when eaten in excess) or eat copious amounts of fats, but want to simultaneously maintain high levels of blood ketones. It may also be used to ease the transition into a ketogenic state, because it can help alleviate the fatigue and lethargy some  people experience while making the transition from a glucose metabolism (carb burning mode) to ketone metabolism (fat burning mode).
Low-carb has become the new low-fat. During the early Atkins era, snacks included cucumbers, beef jerky, and pork rinds. Now there’s a wealth of low-carb snacking options; there are junk-foody low-carb recipes all over Pinterest; a low-carb aisle at the grocery store. There are low-carb replacement foods and ingredients for low-carb replacement foods. It’s Snackwell’s 2.0.
I loved this post, thank you. I tried KETO for 1 day only and I felt terrible. It just wasn’t worth it to me to feel like shit even for one day and I knew I had to study a lot at the time, so I decided that keto is just not for me. But at the same time I felt bad for feeling this way, like something was wrong with me, because I couldn’t even follow a diet, that many people say it’s very easy to follow. And now I just accepted the fact that I love carbs too much to give them up (especially fruit).
You likely heard that a high-fat, low-carb keto diet can melt fat. Because it contains virtually no carbs, a ketogenic diet forces your body to burn fat instead of glucose for fuel. Ketosis is the state your body enters when your liver effectively breaks down fats into ketones to use as energy. Without glucose, your body doesn’t have all the highs and lows that lead to hunger pangs, energy crashes, and cravings. Instead, your blood sugar levels stay stable. Your body also sheds excess weight — fast.
But sadly, whether due to government subsidy of high carb foods like corn and grain, funding from big companies like Gatorade and Powerbar, our sugar-addicted Western palates, or the constant (unfounded) fear mongering about saturated fats and heart disease, the type of research that shows these fat-burning and performance benefits of carbohydrate restriction simply get shoved under the rug.
Keto meals seemed so heavy and rich to me, and it just wasn't how I was used to eating. Plus, I consider myself a flexitarian, so the thought of eating more meat—and more often than I typically would—gave me pause. Dr. Axe assured me that even vegetarians could pull off a keto diet if they planned well enough. (Vegans can, too.) That said, he's a proponent of animal products and red meat specifically, because of the iron it provides for women (who are more susceptible to deficiency) and because it can bolster energy when carbs are lacking. (These Are the Other Things Vegetarians Need to Be Aware of Before Going Keto.)
In addition to the seaweed and glycogen carbohydrates mentioned above, the Inuit can access many plant sources. The stomach contents of caribou contain a large quantity of partially digested lichens and plants, which the Inuit once considered a delicacy. They also harvested reindeer moss and other lichens directly. The extended daylight of the arctic summer led to a profusion of plant life, and they harvested plant parts including berries, roots and stems, as well as mushrooms. They preserved some gathered plant life to eat during winter, often by dipping it in seal fat.[71]

If you would like to read more on ketogenic diets and ketosis, Jeff Volek and Steve Phinney discuss the new method of checking blood ketones in their book "The Art and Science of Low Carbohydrate Performance", and they also offer another good book "The Art and Science of Low Carbohydrate Living", which is a good book for those who need an introduction to the science of ketogenic diets. 

What about fruits and vegetables? All fruits are rich in carbs, but you can have certain fruits (usually berries) in small portions. Vegetables (also rich in carbs) are restricted to leafy greens (such as kale, Swiss chard, spinach), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, and summer squashes. A cup of chopped broccoli has about six carbs.
I really appreciated your post. I feel alone in the anti-keto diet mindset. I was in the diet for 7 months. While there were some things I really liked, less hunger, better control over my hypoglycemia, getting to eat some fatty foods I previously avoided, I did not see the weight loss so many other talk about. I didn’t gain, but there wasn’t hardly any loss. Instead after 7 months, I got really sick. Anything over 3 grams of fat made me incredibly ill and in pain. Ended up my gallbladder had to be removed. I really believe there was a tie between the two. My cholesterol, which has always been very healthy, also started showing slightly high. I have switched over to the everything in moderation and am enjoying food again without the guilt of breaking the diet rules.
That’s right: it turns out that if I could go back and do my year of strict ketosis again, I would do everything you’ve going to discover below. If I had done that, I would have avoided all the uncomfortable, unhealthy issues I experienced when I was eating a high-fat diet, and I would have gotten all the benefits with none of the harm. As a matter of fact, in the past 30 days, as I’ve begun a new journey into ketosis, I am now implementing the exact four methods you’re about to discover.
Protein: Keep in mind that keto is high-fat, and not high-protein, so you don’t need to eat very much meat. Too much protein turns into glucose in the body, making it harder to stay in ketosis. Stick to fatty cuts of grass-fed, pasture-raised, or wild meat, and wild-caught fish. Red meats, offal/organ meats, pork, eggs (preferably pastured), fish, shellfish, and whey protein concentrate.
Hi Ben…first, I have learned so much from you, thank you! I’m interested in using exogenous ketone supplements and I have a question for you. I just read the transcript of an interview Dave Asprey did with Dr. Richard Veech (episode 299). He advises against them, and says they can even be harmful. I was disappointed to read this, and wanted to ask you about it, since I respect your opinion greatly….thank you.

Ketone breath meters: The breath test method, where you blow into a meter, measures acetone levels in the breath. Acetones are one of three types of water-soluble ketone molecules; and in this type of test, the more you have, the farther you are into ketosis.  Breath meters are more accurate than urine strips in determining whether you’re in ketosis or not.
You need to do a “common man’s” version of a good ketogenic nutrition program or discussion. Great article, and I leaned a few things. Those Ketone Salts and other supplements can get pricey. I eat a very low carb and high fat diet and meander in and out of ketosis during the week. A pure ketogenic diet is so restrictive that meals it can get very repetitive during the week. I’d like to learn more about cooking with oils and how temperature effects their qualities. I can only handle eating so much raw food, and I love to cook my greens and other vegetables in bacon fat and coconut oil. It will be next May before I can get my blood work performed (insurance reasons) so until then I’ll need to be careful and hold back on those after supper dark chocolate excursions! Thanks!!
I follow keto and got off 2-Insulins that equaled 5 shots per day and metformin pills @ 1000 mg twice a day and 1 kidney med. Keto has changed my life fior the better. I’m also a health coach for weight loss and nutrition and everyone is different when it comes to weight loss and health. My final #s -95 lbs/22 pants to size 8 and 2x too to small and feel and look great inside and out.
The diet gets billed as a miraculously enjoyable diet—eat all the fat you want, just cut out the carbs. But the ketogenic diet (also called keto) was never supposed to be fun. It was supposed to treat severe epilepsy. And as a medical treatment, it was only intended to be administered under the supervision of trained nutritionists and physicians. The professionals would be able to monitor patients for potential problems and ensure that their diet was actually keeping them in ketosis—a metabolic state where your body switches from using glucose as energy to using ketone bodies, which come from body fat. They needed those checkpoints because staying in true ketosis is exceptionally challenging for adults.
The amount of carbs you can eat while staying in ketosis varies from person to person. If you’re following a strict ketogenic diet, your carb intake will be lower than if you’re following a cyclical ketogenic diet that includes intermittent fasting, like the Bulletproof Diet. Though keto carb calculators offer only a rough guide, they can be useful in figuring out where to start. On a Bulletproof keto diet, aim to eat fewer than 50 grams of carbs a day, and eat them only at dinnertime. Read more on how to find your ideal carb intake here.    
That’s what motivates most people to go keto. “It’s popular because in most cases it can produce very easy and effective weight loss — that’s the primary reason why people start it,” says Los Angeles–based Franziska Spritzler, RD, the founder of Low Carb Dietitian. There are some other researched benefits beyond weight loss, including possibly acting as a mood stabilizer in those with bipolar disorder (per a very small study in Neurocase) and lessening epileptic seizures (according to a study published in May 2016 in Epilepsy & Behavior).
For someone more interested in health/muscle gain rather than weight loss, should I up the protein and good carb levels a bit? I’m around 10% BF and weigh 220, so I require a higher calorie intake the average. In just a few days striving for a Keto-diet, I’m averaging between 50-60g gross carbs (30g net), 160g protein and 220 fat (8%-22%-70%) DO you think that is a good target or should I try and adjust?

Here’s encouragement…it’s not all about weight in the beginning. As you ween off of sugar (which is really poison to your body), your body has to start getting rebooted. I had a solid week or more of serious detox. I knew that getting the poison out of my body was going to be significant, and it was. Don’t be discouraged. It’s well worth it to truly rid your gut and body of cancer-causing poison, not to mention your ability to fight disease. The acid level will change. Your arthritis (joints) will improve. Stick with it and don’t give up. Your family is worth it!

For patients who benefit, half achieve a seizure reduction within five days (if the diet starts with an initial fast of one to two days), three-quarters achieve a reduction within two weeks, and 90% achieve a reduction within 23 days. If the diet does not begin with a fast, the time for half of the patients to achieve an improvement is longer (two weeks) but the long-term seizure reduction rates are unaffected.[43] Parents are encouraged to persist with the diet for at least three months before any final consideration is made regarding efficacy.[9]


I learned a long time ago not to be obsessed with diets for wt. loss. 3 weeks ago I reached a crisis with type II diabetes however and just knew I had to make drastic changes to get it under control. I found the keto diet to be the closest to an extreme decrease in carbs and decided to try it. I these 3 weeks my blood sugar has dropped from 175 to 300 down to 98 to 140. I’ve dropped my insulin from 4 short acting shots and one long acting each day to just the one long acting – and decreased that dose from 55 units to 30. Now I feel stuck on keto, but have the same issues with it that you speak of. Will be trying to tweak it as much as I can to satisfy tastes and convenience yet stay with better blood sugar control. Wt. loss would be nice, but not a main concern, lost 5 lbs so far, but may be just fluid as you say.
Take coconut oil for example. The coconut oil industry loves to market the idea that relatively inexpensive and abundant coconut oil is a great source of MCTs because it’s “62% MCT oil”, but the problem is that studies show you can’t get many useful ketogenic MCT’s from just eating coconut oil or even most brands of “MCT oil”, which are often is diluted with lauric acid, a cheap, hugely abundant part of coconut oil that is typically marketed as an MCT oil.
Thank you for sharing, my husband and i have switched to the keto diet and we love it, we don’t feel restricted at all when it comes to meal planning, i actually feel like we eat more adventurous because we’re always looking for more receipts on how to prepare food. I’ve always done the same dinners, meat, veggies and a rice or pasta side, but with this diet we get to experiment, each night is something new to try. The Ketogenic diet is not about cutting all carbs, just cutting way back on carbs. We have gone and had regular check ups at the doctor with no negative results. I for one have always had an issue with poor digestion but since switching to the keto diet that has drastically changed. The hardest part for me was to cut pasta but i found great joy and fun in finding alternatives to pasta so i can still enjoy the same dish minus the carbs. There are so many different diets out there and so many different types of people so you have to find the right one for you, the keto diet is not for everyone but for us, so far it seems beyond perfect. Thank you again for sharing!
Diabetic ketoacidosis occurs when ketone levels become too high and poison the body. This condition is more common in people with type 1 diabetes because their bodies don’t make insulin. In the event that their ketone level rises, their bodies are unable to produce insulin to slow down this production. If left untreated, this condition can lead to a diabetic coma or death.
Finally, exogenous ketones have been shown to decrease the levels of triglycerides and free fatty acids in the blood after one drink 107 ,106 ,11. There is also early data showing that ketone ester consumption decreases cholesterol biosynthesis in rodents, an effect which appeared to be conserved in humans114. It is unclear at this stage what the long term effects of exogenous ketone consumption on blood lipids and cholesterol would be, but this is an area of promising research. 
“Anecdotally, some people who try keto cycling do find it difficult,” she says. “When you reintroduce carbohydrates back into your diet — and this is more about refined carbs, I’m not talking about eating an apple — you don’t feel very good.” She says some people experience a so-called carb hangover — the body feels kind of bloated and inflamed, and you may develop headaches.
In a recent study in the Journal of Sports Medicine and Physical Fitness, Weiss and his colleagues found that participants performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet, compared to those who’d spent four days on a high-carb diet. Weiss says that the body is in a more acidic state when it’s in ketosis, which may limit its ability to perform at peak levels.

This is why epilepsy patients have to get prescribed diets from profession nutritionists. Without getting into true ketosis, dieters risk ingesting an enormous amount of fat—and potentially a lot of saturated fat, if you’re eating animal meat—without any of the fat-burning effects of ketosis. "The fat is the thing that's problematic for a lot of people on keto," Fung says. "They basically give a pass for any types of fat and a lot of the recipes encourage saturated fats like butter." Dieters who are careful to focus on healthy, unsaturated fats like those in avocados may not have issues, but again Fung notes that you end up with a fairly monotonous diet that way, and thus a lot of people end up eating more saturated fats. "To me as a nutritionist, that's pretty scary."
Tallon, these suggestions are meant to be taken one at a time. If you’ve hit a plateau or are struggling with weight loss, you can try to cut back on your protein. If that doesn’t provide results than maybe that wasn’t the culprit..now try cutting back on dairy, see what happens with that. It’s all about finding what works for you. If you cut out everything at once, you’ll never know which one was causing the issue. Hope that makes sense.
