Jeff Volek - The Many Facets of Keto-Adaptation: Health, Performance, and Beyond

Ғылым және технология

Obesity is a condition of excess fat accumulation in adipocytes where the person is literally stuck in storage mode diverting a disproportionate amount of calories into fat cells as opposed to oxidation. Thus it is more productive to think of obesity as a problem in 'energy flow' rather than energy expenditure (i.e., calories in, calories out). The most efficient approach to accelerate the body's ability to access and burn body fat is to restrict dietary carbohydrate while increasing fat intake for a period of several weeks, after which fatty acids and ketones become the primary fuel at rest and during submaximal exercise. The coordinated set of metabolic adaptations that ensure proper inter-organ fuel supply in the face of low carbohydrate availability is referred to as keto- adaptation. This unique metabolic state has recently been shown to have widespread and profound therapeutic and performance-enhancing effects ranging from reversing type 2 diabetes to shrinking tumors to allowing ultra-endurance runners to set course records. This presentation will discuss the physiologic effects of very low carbohydrate diets with an emphasis on their unique effects on both features of metabolic syndrome and human performance.
Dr. Jeff Volek is a Full Professor in the Department of Kinesiology at the University of Connecticut where he teaches and leads a research team that explores the physiologic impact of various dietary and exercise regimens and nutritional supplements. Dr. Volek's most significant line of work has been a series of studies aimed at better understanding what constitutes a well formulated low carbohydrate diet and the physiological impact on obesity, body composition, fatty acid composition and lipoprotein metabolism, gut micro-biome, adaptations to training and overall metabolic health. This line of work has shown profound effects of ketogenic diets on overall health and well-being, as well as peak performance. He has published more than 250 peer-reviewed manuscripts, many of which were longitudinal interventions of carbohydrate restricted diets. Specific to low carbohydrate diets, Dr. Volek has authored/co-authored 4 books, 60 peer-reviewed manuscripts and reviews, and delivered over 100 invited presentations on low carbohydrate diets in half a dozen countries at scientific and industry meetings. Through more than a decade of research dedicated to better understanding low carbohydrate diets, Dr. Volek has accumulated an enormous amount of laboratory and clinical data on how carbohydrate restricted diets affects human physiology, and acquired a unique knowledge pertaining to the individualization and formulation of safe, effective and sustainable low carbohydrate diets.

    Started keto 12 weeks ago. I was on 80 units of insulin a day. I have had NO insulin in 8 weeks! I am off my blood pressure meds, off statins ( I was taking 100 mgb daily) and off mobic for inflammation. And lost 25 pounds. I didn’t realize how bad these meds made me feel.

    It occurred to me, while listening to Jeff Volek, that our boys and girls in the military might be better keto-adapted in the field, so that if, when they come home, they get stuck into comfort food to relieve their stressful memories and current boredom, this might be a significant cause of the increase in their symptoms of PTSD; a wonderful research opportunity!

    No, MRE's are pretty densely packed with carbs, fats, and proteins. There's no ketoadaptation going on out there unless it's a really bad war and supplies are really really low, and they're rationing. That's not to say they aren't in ketosis. I expect many of them are, frequently, especially the grunts with all of the marches and sweating they gotta do. But it's not consistent enough to be going through ketoadaptation . . . unless they're doing that intentionally, which I'm sure many of them are because the military's all about health and fitness . . . unless you're in the Navy . . .

    I've had trouble losing weight my entire life. It's been as series of diets that i would "stick to" for months with no success. Id lose a few pounds then gain it all back or it would stall. I suffered from weight gain ever since i was a child, not due to being lazy, i was really into sports, still am very active. I was an athlete....who suffered from weight gain. I've been in ketosis now doing this ketogenic diet now for 3 months, after visiting an internist and having a full blood work panel to come back and tell me i was perfectly healthy! besides my weight being obese... And she couldn't tell me why i was having trouble, with a calorie deficient diet and exercise, why i couldn't lose weight. so yes, 3 months later, on a ketogenic diet, i am not finally able to lose weight. 35 pounds to be exact. Yes, the first week was horrible, i craved fettuccine Alfredo and chocolate cake, i felt like an addict. I'm now biking 4-6 miles a day but not every day, more if i can, and lifting weights. I'm eating less than 20g of net carbs and...god guys, if you do this, please PLEASE drink at least 8 glasses of water a day! I havens been this skinny since i was a teenager. I'm feeling more beautiful everyday.

    I keep a mental tally of what I consume each day. I space out 3-4 300 or so calorie meals that are predominately fats. Normally I will start with chai tea with 1 tbsp butter/1-2 tbsp heavy whipping cream. If I am still hungry I may have 2 egg with or without bacon. If I don't have the bacon then, I'll have it later with a tomato with homemade mayo made from coconut oil. Later on I'll have a shake made from 3/4 cup strawberries, 1/4 c heavy whipping cream and 1 ounce cream cheese. Later in the evening I may have more protein or may have vegetables with butter.

    6+ weeks on ketogenic intake. I've eliminated over 225 insulin shots over this period with better control over blood glucose. With insulin & omnivore diet, I would have swings from 55 to nearly 300. I'd always wake in the mornings to 150 to 170 readings (dawn effect). With ketogenics by day 3 sugar readings began to normalize. I now swing between 95 & 135; top spike 150 in 6 werks+. I'm waking with dawn effect fasting reading between 99 & 125. This is proof to me that ketogenics is more effective at regulating my blood sugars than insulin. In fact if I spot check and find sugars drift high in the 130's if I eat some fat only, say a tbs of coconut oil or eat an avocodo my sugars return to a normal 100 to 110 range and remain there over longer periods of time than they ever did with Novolog- fast acting insulin. My insulin would keep me from drifting up for 2 to 2.5 hours. Fat would protect me for up to 5.5 to 6 hours... My first 4 weeks I didn't lose to much weight, maybe 3lbs, because I was consuming 3 to 4k calories from added fat. The last 2 weeks here I have not felt compelled to eat as often so calories have come down to 1300 to 1600 calories and this has me losing nearly 2lbs of fat per week while still feeling fully satisfied. Just remember if you're diabetic 1st you need to get glucose under control & don't focus on getting thin overnight. Focus on blood sugar normalization & reducing insulin secretion. Once you get those two houses in order you will discover inches and weight coming off. Maintain a keto adapted position and every hour of the day you will be burning body fat. You will notice the belt coming in on you as inches disappear with even slight weightless. Stick to it and measure your success quarterly not daily or monthly. This didn't happen to you overnight it happened over a decade or more. What 6 to 9 months or a year investment to reverse these problems in comparison? Remember if you over do carbs or sugars even once it can take you 3 or more days to return to ketosis. Don't blow it and stick to the plan with high fat; moderate protein & low carbohydrate.

    It's 20 weeks on ketogenic now, and I'm still insulin and diabetes medication free. I've gone from size 50 pants to size 42's and still shrinking, and I'm never hungry or dying to eat because I always eat high fat, moderate protein low carb meals. My fasting blood sugar on waking two days ago was a 95. Not bad for a guy that used to wake up to morning fasting sugar levels as high as 170... I'm still ranging in the 90's to 130's with a 60 day average of 115 or so.... Folks, ignore ketogenics at your own peril... If you're diabetic I strongly encourage you to embrace the fat and protein and look at carbohydrates as poison to your bodies.... M

    But I'm going to look into this new drug called Jardiance. It removes over a 24 hour window about 300 calories of sugar via the kidneys into the urine. I'm against insulin until someone confirms my insulin levels are low...I believe with carbs I'm high insulin with poor sugar control due to insulin resistance. A drug that can remove 300 calories of sugar in your blood through your urine is awesome. Our blood is supposed to be maintained with 1.5 teaspoons of sugar max at anytime in our entire system. A reading between 80 - 120 means you are in range. A drug that over a 24 hour period removes 300 calories of sugar from our blood represents eliminating 90+ teaspoons of sugar from the body per day via our urine. I could most likely increase my carbs from a very strict 30 grams a day to say 120 to 150 and still maintain a normal blood sugar with jardiance and still not require insulin. Jardiance is also the first drug to show dramatic improvements in cardio vascular disease with its use... so I'm going to investigate it further... Now I'm well controlled still with my LCHF diet. But it would be nice to eat some extra carbs from time to time if this drug works as advertised...

    Great presentation. One correction: the Swedish government did NOT change their dietary guidelines to a low carb high fat diet. The Swedish Council on Health Technology Assessment did some studies on diabetic and obese people not on the general populations. Of course, this does not invalidate all that Dr. Volek says but it's important to get the facts straight otherwise skeptics will point out that one error and come to the conclusion that therefore the whole diet plan is in error.

    One of the best presentations I've seen. I know that the Navy Seals are testing ketones esters mainly to reduce or to keep from getting seizures from breathing oxygen rebreathers at increased atmospheric pressure. This is being done at the University of South Florida in Tamps. I don't know if they're trying it in their missions. When I was in the Army I went on a 5 day mission with only 11hrs of sleep for the whole 5 days. Towards the end my brain was in a major fog and I had to be extra careful and take more time to do things. The sleep deprivation had much to do with it, but I wonder how I would of done if I was burning ketones. Trying ketone esters on spec ops and just regular soldiers should be tried.

    I am convinced that the beginning of any 'diet' is not what to eat BUT WHAT TO THROW OUT OF YOUR DIET first. Myself, I started by eliminating all grains especially any wheat products then most dairy except quality cheese and of course butter and greatly moderating fruits. I watch people at the gym frantically exercising, sweating in the sauna and still fat around the mid section. Metabolic disorders seem to be their problem, universally, and when informed about increasing fats in their diet and throw out breads, they resist what you say like your asking them to take poison! I noticed a tremendous increase in green bile discharge and liver/gall bladder stones in my stools because of the increased fat stimulating bile flow. The parasites seem to really hate bile (increased alkalinity) since they are also in my stool in large numbers!! The coffee enema might be the answer to those experiencing reactions when beginning the higher fat diet, by helping the elimination process by removing toxins and improving the colon tone and liver health. I also think the Gerson protocol would be more effective if high carb juices were replaced with fats to assist bile flow and flush liver.

    The problem with restricting calories is exactly what you see in the world: a whole lot of fat people. With keto I've been able to lower my calorie intake simply because I'm not hungry all the time. Yes, with a ketogenic diet you can more easily lower your calories. I'm not even in ketosis most of the time yet I'm losing weight because I don't want to snack 12 times a day. I've been fighting obesity since early childhood-yoyo dieter extraordinaire- and I've never felt this good and calm and satisfied and energetic on a diet before. You've been sold a bill o' goods by the food industry, the medical industry and your government, people. Get off the sugar wagon.

Some observations I noted after a month on this diet: plaque on teeth substantially reduced, practically no gas, a fruity flavor in the back of the throat (I use this to know if I am in ketosis), and sudsier urine than before. I also drink about twice as much water than before this diet as I am very thirsty. Jeff mentioned a breath test is forthcoming, but you can taste the acetones (well at least I can).

    @48:00 1.5g/min at 9kcal/g means 13,5kcal/min or 810kcal/h. That is roughly 940 W. Sounds impressive but that is the maximum (short term) gross energy. Since they are endurance athletes, what is the average net power they can put out for let's say 15-30 hours (100 mile trail runs) without carbs? How does that compare to 'conventional' (primarily glucose burning) athletes? Another question: Is there a difference regarding the efficiency of burning fat together with/using carbs vs ketosis? I train my body to burn some fat during long workouts (like 40k of running, burning most of my glycogen, followed by 60k (low to medium intensity) on the bike with just water), and I think I notice that the ratio power output/heart rate decreases whenever the glycogen is roughly >80% depleted. That is, I seem to need more oxygen for the same power output which I suppose indicates lower efficiency...

    I find the most difficult part in keto diet is to consume enough fat. And I don’t see enough fat in your 2500 Kcal day plan to use it in keto adaptation. I see only 6 Tbsp of pure fat there from butter, olive oil and palm oil. Let’s assume the fat in these 6 Tbsp weighs 75g. 9 kcal/g x 75 = 675 kcal. We should also add fat from cheese, beef, sausage, eggs and nuts, which I think could be max 300 kcal. That is less than 1000 fat calories per day or 40% from 2500 kcal. That looks to me like good low-carb, far from keto plan that would require at least 60% fat. Am I wrong in my estimation?

    Ok, so considering the general conception that says, and I quote from wikipedia (I know, shame on me.): "Dietary fat has long been implicated as a driver of insulin resistance." My request is, could I get some links to studies which support the theory that low-carb, high-fat diets reduce your resistance to insulin?

    Also it's true higher levels of saturated fats if included is a sugar rich body is extra bad for you. However a saturated high fat diet with sugar restriction appears to not have any adverse impact to health. It's a double whammy though if you eat high fats with rich carbohydrates. It was mentioned in this video... In all cases carbohydrate or sugars always perform badly within our circulation systems as is evident from studies that clearly show increased inflammatory factors. This fatty acid created in the liver only when it's converting excess sugars into body fat appears to be related to insulin resistance.

    Does anyone know if DPP-4 inhibitors (Gliptins) can either kick you out of ketosis or keep you from becoming keto adapted?

    ***** After not getting any feed-back to my question I decided over the weekend to add a relatively new drug called Nesina which works like a less potent version of a Gliberide/Metformin type of Glucovance along with my 2000 mg daily of Metformin. The two together had little to no effect on lowering my early morning glucose levels regardless of when it was taken; either through out the day or all right after my last meal. So....I decided to take the plunge and add the Glimeperide into my med regimen as well as the other two. A 4mg dose of the Glimeperide caused my early morning readings to come down to 71 which is wonderful. However, the additional insulin created by my pancreas has kicked me out of ketosis....which is what I was concerned about. So....I have answered my own question with my little experiment and now am focusing on getting my blood sugars (early morning) consistently below 80 and no higher than 100 without my blood sugar crashing and having to "carb up" to get them up and stable again. So far with my experimenting I've been able to do just that. I think I will next see if the Metformin and Nesina make a difference when combined with the Glimeperide by cutting back the dosage of either or both. My doctor is not a hand-holder and is like "Try it and tell me what happens.", so I will conduct these little experiments and let you all know what's up. On the bright side the ketogenic diet I have been on has been extremely anabolic and I have packed on massive amounts of muscle from intense weight lifting 45 minutes a day; 5 days a week. I was hoping the keto-adaption would kick in pretty soon so I could start intermittent fasting along with some cardio and shed about 30 lbs of fat that's covering all these beautiful muscles underneath! I know my wife would like that as well! LOL! Thanks again!

    ***** Hi Jason. Let me first say that I have nothing to do with the medical "profession" and have only a basic knowledge which could be wrong. So you can take or leave my advice. But, I'm thinking that you have 2 problems. One, you're diabetic and need to get your glucose levels down below the 'norm' of 100, I'm right there with you. Two, you are overweight, typical for us diabetics, and are working out like a crazy man to get the weight off. May I suggest you concentrate on the first problem and once that's accomplished, a lowered glucose level, you may find that the second problem, being overweight, is also being worked on. I'm overweight and desperately want these nearly 100lbs off but as that study on twins shows, exercise won't remove the weight. The ketogenic diet will remove the weight, having low glucose/insulin levels will remove the weight. It's slow, I also want to hit the gym, but I'm seeing waist and hip measurements going down so I'm sticking to the diet. I worry that you are over-medicating yourself, especially as it appears your doctor doesn't appear to care what you're doing. And you are over-exercising which may be affecting your diet, eating more to build muscle which effects metabolism and may be why your glucose levels are not naturally lowering. Take a month to concentrate only on your diet and lowering your glucose and getting off or reducing the meds, stay out of the gym or just do minimal workouts, and see where you are then. I think your wife would like your levels lowered and you alive than ripped and dead. Good luck.

    I hope someone can help me with this. I have been insulin resistant for many years and have been on a keto diet for several weeks now, yet my blood sugars while continuing to take Metformin, Chromium and Cinnamon at meals is still high; around 160 in the morning to 100 in the afternoon after eating all day. I have a prescription of Glimeperide which stimulates the pancreas to release more insulin, BUT I don't know the effect it will have. You see, I have the keto flu, I am in ketosis, but not keto-adapted yet. The concern is that if I don't get my blood sugars consistently below 100 will that have a negative impact on my finally become keto-adapted, but IF I use the Glimeperide to decrease my blood sugars which does work for me...but I need to be careful to not to take to much then drop to where I have to take in a bunch of glucose to get the numbers back up to a safe range which will KNOCK ME OUT of ketosis altogether and THEN I would have to start all over again. SO...does Glimeperide have a detrimental effect on becoming keto-adapted and/or does high blood sugars in the range I mentioned above keep me from becoming keto-adapted as well. Please help with this vicious paradoxical circle! Thanks!

    Jason read my post from earlier. I'm 6 weeks into remission and I'm a guy that was shooting insulin 5 or more times a day. I take zero, zilch, none, nada diabetes drugs. Prior to ketogenics I was using insulin and metformin and eating a normal omnivore diet. Despite using drug to try and normalize glucose I found the more I used them the worse I was getting with ever increasing dosages to try and maintain my sugars. 6 weeks ago I went ketogenic with 75% fat; 20% protein &5% carbohydrates. In 3 days my sugars started to normalize better than they did with insulin. You have two possibly 3 factors working against you: 1.high blood sugar 2. High insulin with high blood sugar 3. High cortisol via stress factors. You must eat to lower blood sugar and lower insulin secretion. That's why you need a much higher level of fat. FAT DOESN'T RAISE EITHER BLOOD SUGARS OR INSULIN. Moderate protein... why? Eat to much you will invoke insulin secretions as well as raise glucose if you eat to much of it. You really only need 9 to 12 oz per day to maintain muscle. Strictly limit carbohydrates. I try to stay under 30g. If I spot check glucose and it's creeping up I eat avocado or coconut oil the fats in them lower blood sugar and maintain it lower than my insulin does. Don't cheat. 1. Once you kick yourself out of ketosis it can take 3 or more days to get back into ketosis. Don't waste your time thinking cheating won't hurt you because it will...

    I can only warn you to watch your liquids, sugars in fruit drinks /alchohol and everything processed can screw yor metabolism. Good luck and have patience (I've heard all sorts can be stored in fat deposits which can make people suffer before they enter ketosis. If you continue having problems either try the 'snake diet' where you eat once a day or fasting, which takes 3 days and yor in ketosis or autolysis, where you eat yorself! X

    Also checkout Mark Sisson, carbs can be an effective fuel, but for some people they can cause lots of inflammation. I think it may depend on metabolic type as well as tolerance to carbohydrates and tolerance to fat.

    Jeff Volek has said about several health benefits on the Low Carb High Fat diet BUT said nothing about cholesterol level changes. Can you answer my question: Is increased level of cholesterol thing to worry on LCHF diet? MY CHOLESTEROL LEVEL INCREASED after 3 months of following Low Carb High Fat diet. My age is 33.My results are;; LDL: 324 mg/dl HDL: 100 mg/dl TRIGLICERIDE: 60 mg/dl TOTAL CHOLESTEROL: 324 mg/dl When I tested my Cholesterol level 2 years ago on the balanced diet it was within reference range. CAN ANYONE ADVISE?

    Your total and your ldl shouldn't match, I'm sure it's a typo, but your numbers are pretty wonderful. You HDL is wonderful and so are your triglycerides so I'm sure your worry is about LDL and total. LDL is not all bad, in fact it's vital, what I don't see is your V-LDL which isn't as good. Also you number are probably calculated as that is the standard test, if you ask your doctor for more specific testing that is more costly they can tell you a more accurate numbers. So in the end focus on your excellent HDL and triglycerides, because those are the real markers of cholesterol health. You may want to pick up cholesterol clarity by Jimmy Moore it's a light read and is pretty good at explaining what's happening to you. Also in this video there are some graphs showing how low carb raises HDL, the undisputed healthy marker. My brother had a heart attack because low cholesterol.

    He did have several slides in this presentation that illustrated tremendous improvement to cholesterol. All clinical studies show improvements in HDL & LDL small particulate (the harmful HDL) large particulate LDL usually increases though and is harmless and necessary for health. Remember without LDL you would be alive either. We need both HDL & LDL to live.
