6 RD-Backed Reasons Eating Fat Promotes Weight Loss. Fat plays a fundamental role in a healthy diet. The macronutrient is necessary for cellular growth, supporting healthier skin and hair and regulating the body’s metabolic functions. Fats keep our hormones in balance and help us absorb key nutrients like vitamins A, D, E and K (there’s a reason they’re called fat. 6 RD-Backed Reasons Eating Fat Promotes Weight Loss myfitnesspal.com | 2d Fat plays a fundamental role in a healthy diet.

The macronutrient is necessary for cellular growth, supporting healthier skin and hair and regulating the body’s metabolic functions. An RD explains what causes a weight loss plateau while intermittent fasting, like overeating, consuming the wrong foods, missing sleep, and hormone issues. Muscle loss, or muscle wasting, can lead to unexpected weight loss.The major symptom is muscle weakness. One of your limbs may even look smaller than the other.

Your body is made of fat. If you really wanted to understand the impact of a low-fat diet on weight loss (or some better marker of actual fat loss), it seems that actually looking at trials where this was being tested might be a better place to look. There is no shortage of such trials out there, including the work of Gardner, Foster, Ludwig, Dashti, Shai, and others.

Eating more fat means eating fewer carbs, and vice versa. From a fat-loss perspective, displacing carbohydrates by increasing fat in your diet sets the stage for an optimal fat-loss environment. Insulin, released by your body in proportion to the amount of carbohydrates you eat, is the major gatekeeper when it comes to nutrient partitioning. Capsaicin supplements may boost your metabolism, enabling you to more easily lose weight and burn fat (6, 7, 8).

Capsaicin works by increasing oxygen consumption and body temperature, which leads. Unexplained weight loss can occasionally be a sign of cancer. Learn about other potential cancer symptoms and the many other causes of unexplained weight loss.

When you’re trying to lose weight, eat regular meals and consume 90% of your calories before 8 p.m. The benefit of eating meals every three to four hours is it helps regulate your blood sugar. It emphasizes eating plenty of fruits, vegetables, whole grains, and lean meats and is low in salt, red meat, added sugars, and fat.

While the DASH diet is not a weight loss diet.

The short-chain fatty acids from whole grains may also help us eat less because they stimulate fat cells in our stomachs to release leptin, the satiety hormone.

The Secret behind such seemingly contradictory observations is that weight losses may be due not only to loss of fat, but also to losses of variable amounts of water and protein from the lean tissues of the body.

In conclusion, these same people who were actually gaining weight on a 1,000 calorie per day, carbohydrate inclusive diet started losing weight on a 2,600 calorie per day, high-fat diet—additional, compelling evidence that a calorie is certainly NOT a calorie!

When similar caloric levels occur between lowerfat and higher-fat diets, similar amounts of weight loss were reported in two studies, 364, 443 whereas one study showed 1.8 kg (4 lb) greater weight loss on the lower-fat compared with the higher-fat diet, despite similar reported calorie levels.

This indicates that a substantial reduction in fat intake may result in overall caloric reduction, perhaps because of the caloric density of dietary fat.

The result of these changes is that your brain becomes much less sensitive to leptin (as we discussed in Chapter 1) and insulin, another hormone that helps regulate fat.

  • Oz has stolen the whole study from Dr Eric Berg…What a SHAME! Check on Dr. Berg YouTube to know the original study and even the best-selling book he wrote about the subject!

  • fraud / noun:
    wrongful or criminal deception intended to result in financial or personal gain.
    Dr. Oz stole this body type information from Dr. Eric BERG.
    LOL….. the diet information Dr. Oz recommends is inaccurate.

  • Fantastic lecture Dr. Bikman
    How would you explain constant blood ketone levels between 0.1 and 0.5 mmol/L in subjects eating one meal per day consisting only of fatty fish and fatty meat?

  • When you let your smartphone discharge, does it lose weight?
    Think about it. Chemical energy = molecule bounds. Atoms arent “burnt”.
    It’s the same with calories, “burning” calories does not mean weight loss.
    Weight is lost only by losing ATOMS: breathing out carbon, pissing, sweating…

  • At the end of the day, the issue is controlling insulin production. Chronic stress can definitely play a role in this because chronically elevated cortisol levels can raise insulin production. So getting quality sleep is very important. But perhaps even more importantly is nutrition. That may be the most important. The big four to handle are stress, sleep, nutrition, exercise.

  • Always thoroughly enjoy Paul, but highest iron levels I thought is in liver, is this considered red meat or is the iron in liver not harem iron (it is full of blood as well)

  • So, is this an argument in support of exogenous ketones? I have never known of any other specific purpose for ketones besides fueling the brain. Besides ketosis being an indication of fat burn in my effort to lose weight, I was trying to minimize the effects of AD for my mother who was physically very healthy and whose family trend was toward great longevity. I did not want her to be alive, but bedridden for years due to the physical ravages of Alzheimer’s. I’ll never know exactly how much our efforts helped her but I will say that her AD was evident for well over ten years and yet she never got the debilitating physical effects of it. It was only her cognitive ability that was affected and that was relatively mild.

    Forgive my digression into a hot-button topic for me. My point is that I never understood a purpose for ketones in a weight loss context other than what we generate through the fat burning effects of carbohydrate reduction (fueling the brain in the absence of glucose). The use of exogenous ketones as a fat burning tool seemed to me like using extra smoke to increase the efficiency of a trash fire. This lecture now has me wondering if exogenous ketones would be useful for the conversion of brown fat to white fat and the benefits that would impart.

    He doesn’t say to take more ketones to lose weight but I wonder if this information would support it.

  • All I have to say is… Not saying your wrong in any way… And as you probably know… Everyone needs a different diet… Need to look at what your body does with fats… If it stores it in the bloodstream that is not good… Other sources of energy… But yes… Lots of energy in carbohydrates… But will not go through your bloodstream as fat… Salt… High blood pressure… Bloodstream stores salts… Body type… Be content with your body… In fact love it… Bloodstream bloodstream bloodstream… High fibre to fill stomach… Good for cleaning the intestines… Vegables high in vitamins… Fibre… When you say slowly eat less stomachs will get smaller… Acts like an elastic band… But vegetables to fill but not over fill… Etc etc etc…

  • I love your show. The eyes you had very good Vice on your shows concerning people health issues and other situations God bless you you keep up the good work you are doing to also and I pray that God continue blessing your show

  • Hah, guy on the rights going on about eating a slice of pizza or a burger now and sign. WHAT ABOUT THE FUCKING ROIDS he’s PUMPING!!!!
    Fuck me……..why am I alone here?

  • See, I’m actually underweight and want to gain to be healthy but the minute I put on a pound I immediately develop I gigantic beer gut. I’d do anything to be an estrogen type, girls with big bums are hot as fuck

  • Dr Oz didn’t come up with this. Dr. Eric Berg did!! Ovary, Adrenal, Thyroid, and Liver Body Types! I can’t see Dr. Oz the same way anymore! Jerk!

  • I watched it once. Then sat down and watched it again this time taking NOTES. I needed to participate in order to fully absorb what he was teaching. Great stuff! Information like this helps people like me say no to carbs with a sense of purpose. No insulin thank you. I’ll be eating ketones for the win. Go Chiefs!

  • I have long legs thigh gap wide hips small waist heart shape butt boulder shoulders I love my face and I think I’m a very healthy skinny so I’m lucky I get complimented on my skinny jeans because my legs and butt look fine! and I never get fat

  • Just watched a video from Dr. Berg. Dr. Oz straight out stole the body types from Dr. Berg! Dr. Berg is the only expert I can rely on for honest real information, not some dupe with a TV Show. Shame on you Dr. Oz! Have you no ethics or morals? I’m calling you out and exposing you and the network for what you did to Dr. Berg. Shame on you!

  • Dr Oz is a fraud he stole this from Dr Berg the originator of the “body type” if you want to know the real info on it go to Dr Berg.

  • This is actually Dr. Eric Burg’s sources and material. This is absolutely immoral, illegal and called plagiarism. This is not fair and they should be sued for coping other people’s material without their consent.

  • Keto diets increase the risk of fatty livers. The various ketogenic diets that severely restrict all carbohydrates and replace them mostly with fats are associated with increased risk for non-alcoholic fatty liver disease or NAFLD (JAMA Intern Med, published online July 15, 2019). NAFLD can lead to diabetes, heart attacks, strokes, liver cancer and other cancers (Curr Opin Clin Nutr Metab Care, Jul 1, 2012;15(4):374-380). Ketogenic diets have also been associated with kidney stones, constipation, diarrhea, fatigue, headaches, bad breath, bone fractures, and an increase in LDL cholesterol that increases risk for heart disease. Ketogenic diets increase markers of cholesterol and inflammation, although they do lower triglycerides (Obesity, June 2019;27(6):971-981). https://www.drmirkin.com/nutrition/keto-diets-increase-risk-for-fatty-liver.html

    Herbal supplements have existed for thousands of years and can be traced over several different cultures. For now. Herbs are now used to cure diabetics, herpes, chronic pain, asthma,hepatitis b, cancer, ALS, Ovarian Cyst and even  GENITAL HERPES. I like herbs so much. Most of the time, the injection and the drug are only a loss of duration. I was cured of GENITAL HERPES  last year with the use of herbs, I suffered from GENITAL HERPES  for 13 years, but with the help of DR. Hazim Usman  Herbal Medicine, I was cured in a few weeks of using the herbs he sent me by UPS Service Delivery. I don’t know the kind of health problem you are facing right now, but I assured you that you will be cured if you contact Dr. Hazim Usman and explain your problem to him, that the issues will resolve in a few weeks, contact Dr. Hazim Usman via his e-mail address:-( [email protected] )-or reach him via

  • The body typing concept makes the best sense. We too, have developed a system of body typing and can provide dietary ad supplement outlines for each of them. The one he labels the sugar types would more accurately be called the carbohydrate intolerant and most often stems from an over production of insulin in response to carbohydrate ingestion. One of the primary functions of insulin is to remove glucose from the blood and store it in the form of triglycerides, in the fat cells. This process has no stoppage gap and most often accounts for those who are a hundred pounds or more over weight. We have designed a special program for these individuals who on average, account for 60 % or more of all obese individuals.

  • You shouldn’t look at food in terms of carbs protein and fat. Look at it in terms of FIBER, protein and fat. If the carbs you’re eating contain little to no fiber then you shouldn’t be eating those carbs. If your carbs contain 2g of fiber or more then those carbs are probably very good for you. Fiber is just as important to your body as protein. Insoluble fiber helps you digest food. Soluble fiber helps regulate blood sugar and insulin and will help you from developing type 2 diabetes and high blood pressure. You NEED carbs and protein. Any diet that would have you drastically lower your intake of good carbs is NOT a credible diet and can cause harmful effects to your body. Same goes for low protein diets. Your body needs both in order to function optimally.

    Also, fat does not make you fat. Good fats that come from nuts, seeds or fatty plant foods are critical to your body’s ability to make stress managing hormones and helps your brain function. Any diet that tells you not to eat whole food plant based fats is not a diet you should follow.

  • Not sure, I may have already posted. But this KWOE has changed my life. Today, I am down a whopping -99 lbs. BP 118/68. Fasting morning BS 94. This thumbnail was me at 305lbs. Today 206…still a way to go, but I’m so grateful for the truthful science Dr. Bikmen shares with us. LCHF is practically effortless in month #10. My body prefers fat for fuel. Thank you, Thank you, Thank you!!!

  • eat for your blood type, get off the couch and MOVE like your ancestors did, shun processed and GMO foods, and do NOT drink soda, drink clean water, not found in a bottle, you will not have issues.

  • Dr. Oz you are a piece of shit thief. You conned Dr. Berg out of giving you information with the promise of being on your show. Then you cancelled last minute, changed the narrative to avoid Berg’s proven solutions, and pointed people in the direction of failure so they end up relying on big pharma. You’re disgusting.

  • This issue of water before and after meals is quite confusing for me, here dr Ian says you can have your water just before your meal, have heard from other sources that taking water shortly before meals dilutes the digestive juices!!!so now which is which?

  • Wonderful interview gentlemen! Full of golden nuggets; practical advice and precious anecdotes. ‘ll look forward to the next one:)

  • I am starting intermittent fasting again. I had a rest from it. I came across this video and I must say the Host Ed Mylett and his guest Dr Ian Smith are both humble and gracious people. I appreciate your interview. fantastic!!

  • Dude I’m sorry, I love some of your videos but this is so far off the mark. At first you will lose weight when you begin intermittent fasting but once your body adjusts to the diet it will begin to hold on to fat. I’ve been on this diet over 3 years and I can tell you I eat a fraction of what I once ate when beginning this diet and despite this I am just as big as when I started.
    Weight loss is best done with frequent heathy meals and exercise.

  • Girls should never ever use weights on their arms a lot.bulking up takes your boobs away.all gym nuts have fake boobs.look at their bony chests in the middle of their boobs.just do regular exercises.train the rest of your body not arms with weights.
    Fat moves from boobs to side then you look like a man.

  • incorrect 12 hours aint shit fat burning dont start till the 17th hour….i been on IF for 3 years in a row now…….if your rellly fat like the average american is than 12 wont do shit……

  • This is a blessing especially this one ( Don’t do things becouse it’s expected of you ) omg this is great message God bless you guys

  • It really works Iost over 40 lbs. Now I do eat pizza but only gluten free and with vegetables only. I was told that if you do not go to the bathroom within 2 to 4 hours then your body is having a hard time breaking it down. This rule has worked for me. I get a lot of compliments and ask me how I am getting younger.

  • Dr. Smith I am over weight. I broke my back & lost 20% of my height.
    I am way older than U R so I have almost no hormones.
    My Leptin, insulin & cortisol R messed up.
    I can’t afford to see a Functional Doctor, so can’t get tested.
    I know about Dr. Westin Childs who isn’t covered by my insurance & is in Az.
    I am in Ca.
    The only way I ever lost the deep fat which is in my belly.
    I am in so much pain via AS,OA,FM COPD & the diabetes issues..
    So I can’t exercise due to excruciating pain.
    I do try to fast. have no problem not eating for hours, but I am not losing any weight.
    I do walk as best I can when the pain isn’t so bad I can’t take a step.
    So how can I ever lose a lb??

    I’m really at the end of my rope.
    I eat pretty clean. I don’t eat much processed food.
    I eat some fresh fruit,some meat,fish, & veggies.
    Very little dairy. Some eggs & some lactose free cream or nut milks.
    I try to drink as much water as I can,but I have bladder issues meaning I must go to the bathroom every 10 mins.
    Anyhow hope U have some ideas for me…
    I am on my own in horrific pain 24/7 so doing most things R such a chore.
    I do take supplements.
    What has me confused is should I take bio identical hormones, NMN, HGH or other things to put my body back into my younger years?

  • Most of his “advice” is great. I am not sure about drinking water right before you eat because that dilutes your stomach acids. That’s why it’s best not to drink during meals. Best is to drink 20 minutes before and 20 minutes after, perhaps, if you want/need.

  • Every single muslim I know fasts, its something muslims have been doing since the start of islam. Interesting seeing non-islamic cultures finally realize the benefits of fasting in recent years….

  • This is brilliant information, I want to start fasting today, I just need to know how many hours per days and how many days per week, does it depend on the diet you want to do? I.E. the 5/2 diet,
    Let me know please,
    Great show, great guys!

  • I am so upset I paid to take your challenge and I have yet to get the app to participate I have emailed many times and no one ever answers. Is this some kind of scam

  • Sooo interesting. I practiced intermedient fasting for years. As soon as Co vid began, I was thrown out of whack. I panicked. Now, 20 lbs. overweight, I realize, duh go back to the basics again. I always maintained no eating after 7 pm., no refined sugar. Thank you so much for this interview. I was almost going to try Nutri System. Processed food, high sugar content.

  • Great Informative Video! Here’s a Suggestion Hey, I have been having good weight loss success on my new Shake meal program! Takeahealthjump.com I have been losing more inches however, lots of Brain Energy! All you need to do is try 1 bag to become a believer! I recommend the CORE (Whey) or VPro (Plant Based)! No Soy or Sucralose!

  • Women should intermittently fast differently because we have to take into consideration our hormones. Look it up. Good interview tho!!

  • I didn’t even know you could get an iron infusion! How has no doctor ever told me this whilst I’m bleeding out every month? Thank you for this invaluable information.

  • Such a dangerous message. Please study the work of Esselstyn, McDougall, Campbell, Popper, Fuhrman, Goldhamer and other Plant Based doctors. Most of all STUDY THE WORD OF WISDOM! Part of your faith! Wheat is for man, fruit is for man, and he even tells us “It pleases me if you only eat meat in time of famine cold and winter.” Insulin sensitivity can return when you eliminate fat from your diet. The cells that are full of fat release the fat and can now accept glucose. Your message is encouraging and adding to insulin resistance. There is so much more to this than not using your insulin. Are you teaching this to your students at BYU? Dangerous.

  • This is a great interview with Dr. Smith. I also hesitated watching because of the length but enjoyed every minute of it! Probably going to buy the book. Thank you Ed for this interview.

  • Also I’m curious if there is a ceiling to this behavioral transfer between WAT & BAT and would the ceiling even be a substantial difference in a BMR bump?

  • My second comment after watching / absorbing this info a few times 1. When knowledge speaks it comes across much clearer and concise as opposed to internet bros who think they know something. 2. Host genuinely interested in the point of view and didn’t get in the way. 3. Made me more motivated to chase a better lifestyle for myself. Great job

  • Doctor OZ used Dr. Eric BERGS information and put a fake doctor on to use Eric BERGS information!
    DOCTOR OZ shame on you!! I won’t ever view or listen to you again!!

  • Excellent interview! I enjoyed every minute. Thank you Dr. Ian for all your knowledge on eating healthier. You life experience..going to College,,talking about your single mother raising 2sons( I have 3 ) I’m so glad to hear that you’re a God fearing Man! God Bless you mightily! You Guys conversation was on point. My sister and niece were trying to do keto…l knew it wasn’t the best for them to do. So I shared your interview just now. Thank you so much. You’ve truly inspired me to lose weight without feeling miserable about doing it. Take care! ����

  • I loved this. I was looking for information on intermediate fasting and ended up getting more than what I originally came for. This conversation was so intriguing, I will definitely be adding this book to my reading list.
    Awesome segment, Thank you gentleman.

  • There are no essential carbs. I have never been healthier with more energy since ceasing carbs. You have no understanding of Keto. Some people can’t process carbs without becoming inflamed. You have a lot to learn.

  • Well, update. Dr. Smith is a shill. He has evidently signed a deal with the devil and now it’s come back to bite him. He sold his soul for ‘success’. Intelligent guy. Pizza in New York? Rainbow Cake Chicago Bulls? I knew something was out of place. Hope it was worth is Dr. Smith. IT. ALL. ENDS. SOON. THIS -> https://twitter.com/DrIanSmith/status/1288120209669152768

  • Mr. Mylett and Dr. Smith. I don’t know either one of you. Until now, I had never even seen either one of your faces. BRAVO! THIS video I just forwarded onto my three sons as a MUST WATCH (17, 14, 12) -> “Fellas,… a MUST WATCH… from start to finish… don’t miss the end!!” Thank you so much.

  • I was listening to your thoughts on Keto. Now I have studied Keto and I do it with intermittent fasting and do also have a cheat day where I do a larger amount of Carbs on that day. Now I try my best to avoid added sugars etc but do do some fruits as well I do 16-18 hours a day fasting and find that I have all the energy under the sun I need The body does not need high sugar and the brain needs Ketones more than Glucose as Ketones are a much cleaner source of energy. Further the Keto diet is not high protein it is moderate Protein high healthy fats and low Net Carbs. I do consume low carb veggies on my keto days but do not exceed 20 grams which is a lot of spinach for example and just avoid starchy veggies. The starchy veggies are for the cheat days.

  • Heme iron is a confirmed oxidizing agent. It is connected to type 2 diabetes and cardiovascular risks. Another reason to ditch red meat.

  • This video was just what I needed, 2 respectful & intelligent gentlemen!
    Unsuccessful at Keto, always struggled with drinking water!
    Dr. Berg’s whiteboard gives me a headache & DeLauer makes me anxious….worth the wait!!!

  • He is correct about the upper crust. They are very sly devious and cunning. Fueled by ego greed lust for power and control. Sone of the worst traits in a man.

  • Great interviewee authentic and informative. And a great interviewer brilliant to see such humility and courtesy towards the guest. Refreshing for YouTube!

  • If you drink just before eating you dilute digestive acid making digestion then getting nutrients harder. Also you may deplete yourself from minerals. See Dr, Tent’s Mineral crisis of America.

  • Ed, you’re a wonderful interviewer! You listen more than speak, and when you do speak, you are sincere, eater to learn, you lift people up. Thank you for your enthusiasm to better yourself.

  • Seems like the reason our bodies want to produce heat is because famines tend to happen during the winter? And if you’re not eating (fasting), you tend to shift into ketosis…? Although, when I’m in a few day fast, I tend to feel colder than usual.

  • So how long until doctors are advertising UCP injections to obese people and telling them to just watch TV with an ice pack and let the fat just melt away?

  • At 15:50….is that mentioning using placebo’s on non-humans? Is that even a placebo? Interesting. Amazing content though. Love the wealth of knowledge from Dr. Ben.

  • Dr Oz show ripped off this info from A very good doctor call Dr berg check out his YouTube channel it shits on the Dr Oz Show with great info to a healthier life

  • For the year and a half, I’ve done 20-24 hr dry fasts 3-4 times a week. Also I’ve only taken daily cold showers. Now, I haven’t totally stopped my carb in take, but I suspect the dry fasts have upregulated my mitochondrial activity and increased my brown fat. In the past when I would sleep (especially in the winter), I would curl up in my blanket all night long, especially during the winter. This has been since I was a kid. Now I find myself waking up in the night having to remove the blanket cause I feel hot. If I haven’t thrown off my blanket, I’m a lot more sweaty as compared to before. The last time I did this regularly was when I was a kid. This was probably a time when I had more brown fat and wasn’t the product of decades of carb intake.

  • What is my body types please.
    The area around the shoulders89 cm
    The area around my chest 83 cm
    The area around my waist 59cm
    Buttocks perimeter 87cm… please help me

  • Thank you so much! Such excellent info. I now suspect tannins (my daily coffee’s) are hindering my carnivore diet goals. Damnit:(

  • IS IT NORMAL????

    My 10 y/o son blood results:
    A1C 5,2
    Fasting blood Glucose 72.
    Fasting blood insulin 1,69.

    Is it bad that the insulin is too low??? But looks sufficient because the A1C is 5.2 and the fasting blood sugar is only 72.
    Also he’s not really underweight, but he’s on the lean side.
    Also he gets easily tired �� when playing soccer ⚽️.

    Hope to hear from you guys.
    I don’t know who to consult with. Regular doctor don’t understand metabolism.

    Thank you very much.

  • So if you take an exogenous ketone supplement, while still taking in carbs that elevate insulin, do they cancel each other out or does one trump the other?

  • I have been very strictly to pretty much keto for about 18 months. I devour information on keto, health, and weight loss. This is the 1st time I have seen an actual reason why eating so much fat is a good thing when inducing ketosis. I hate blindly following instructions, and love knowing why I should do things. More dietary fat means less insulin. This also explains when I began the keto diet, I was so hot, and minimal exertion would cause me to sweat uncontrollably. I could take a long cold shower, and before I could dry off, I was sweating again. When fat is “burned” it actually is turned into carbon dioxide, and water. If you are more rapidly burning fat than can be expelled as water and carbon dioxide, breathing and whizzing out ketones (converted fat) makes perfect sense. This is the best explanation of the ketogenic diet I have ever seen.

  • As a health professional I find myself angry at the ignorance of our current dietary teachings. These have not helped anyone. I am so grateful that teachers such as Dr. Bikman are proving them wrong.

  • The thing i never se clearly explained is of you can go into ketonegensis if you have insulin resistance or if our are in cetosis can you have insulin resistance at the same time

  • Great talk! What I found fascinating was the graph from the David Ludwig study starting at 26:30, where the metabolic rate for the low carb high fat diet continues to rise and stay high for 4-6 hours after the meal. Are there any other studies that have built on this study by looking at meal frequency and IF over a longer time span 24-72 hours?

  • Go to DR. Eric Berg. Doc. OZ is a thief and “bought out” elitist. He can’t help you! This info is 70% wrong because he stole it and changed it. If you want to get the real information go to the Dr. that published this and Oz stole it and changed it.

  • wow, this is happening in my body. I feel hotter and my wife feels the heat also. so the ketones she smells is my fat burning. this really helps me understand what is happening.

  • Sounds like our bodies need meat and fat, and can eat plants if very necessary and in eating the plants(carbohydrates) we produce more insulin to store fat when we have to resort to more of a plant diet in hard times basically.

  • I hate the way they speak of health. like “…nudges you over the finish line.” like nutrition’s is not a race that you do once and then end…its a lifestyle change you must make. Its reprogramming your body to eat real foods that are good for you. why cant they separate the health and loosing weight and why the hell don’t they ever talk about gaining good weight.

  • I have watched this several times… and this lecture is one of the best lectures that describes the rudimentary mechanisms of the metabolic effect of food. Thank you for al, your heard work.

  • If anybody wants this in more scientific and historic detail, please watch The Aetiology of Obesity by Dr. Fung. It is a 6-8 hour lecture on the same topic.

  • I’m suggesting this out of ignorance, But isn’t gluconeogensis very energetically inefficient?

    Due to the higher concentrations of glucose, glucose-6-p, glucose-1,6-bp and early substrates of glycolysis, wouldn’t this make the non-standard state delta G of the steps involved in gluconeogensis very energetically costly requiring a lot of atp?
    So if you were to decrease carbohydrates intake, wouldn’t your body need to go through a very energetically inefficient gluconeogensis to restore blood glucose concentrations, using a lot of ATP?
    And also the low glucose effects on hormones (insulin) that would upregulate fat burning enzymes in order to make the atp needed to fuel gluconeogensis?

  • ah i have been trying to lose weight for like 2 years (im 17 now) but i would lose very little weight and then gain alot, i got sick of me trying for nothing and asked dad to go to a dietition, after 2 months with her and only losing 1.8kg in total she recommended i do some blood tests, my hgb was 11.6, ferretin was at a 3.5, b12 was low, my mcv, mchc and mch were all low e.g. m.c.h. was 23.1, my RDW was high (18.8%), my HDL was 52 and LDL was at a 123. i took an iron infusion a couple of days ago and i am on statins and b12 pills. I really hope i get better and start losing weight!!!!!

  • Any help would be appreciated, it seems impossible to eat over 1200 calories, I don’t mind eating some fat (Bacon, porkroll, scrapple, etc), but other than that, living on meat, sardines, eggs, cream, butter, etc is resulting in reduced caloric intake, my concern is about metabolic rate reduction due to reduced caloric intake.

  • I’m confused. Many of us have been told by doctors, hospitals & even the internet, that brown fat is dangerous. R U saying that it’s actually beneficial to adults?

  • My diet consists of full-fat raw milk, raw milk cheese, cultured sour cream, raw milk kefir, organic lard, organic rendered duck fat, bone broth, grass-fed butter, pasture raised eggs and sourdough. All of these foods are anti-inflammatory, heal the gut, and build up the immune system.

  • So, where does Ketoacidosis come into this, or, by ‘high’ ketones, do you mean still below this level? Because this sounds dangerously close to the abuse a Type 1 diabetic can wreak on themselves in order to lose weight.

  • Ketogenic wasting probably includes perspiration as well as the other two means because my body odor changes during ketosis indicating that sweat may be another way to waste.

  • A very informative talk! However, as a next step would be interesting to understand wider physiological effects of the ketogenetic diet, I.e. cardiovascular health, dementia and cancer. As well, if this type of diet can be used during the whole human life span or only at certain pre-diabetic states. Again, well done!

  • Excellent talk…Good for those on Keto and also for those in Intermittent fasting. A must watch for Diabetics to understand more about what’s going on in their bodies.

  • Although not speaking to some very important mechanisms, this was a very informative lecture.

    Having said that, with time restricted feeding, I eat nothing but green, yellow,and starchy vegetables, the occasional fruit, legumes,, select whole intact grains and seeds yet have fasting insulin levels below “normal” �� range. I also WOF (nature’s true keto) for 2 days, 64 hours, as occasional resets.Curious.

    mTOR, IGF-1, telomeres all good

  • Since I am always cold, I wish he explained how we could make more brown fat cells or make those bitches work freaking harder! Why the hell am I always cold?!

  • Where have I heard this before? Since 2011?? Oh yeah Dr. Berg. Thanks for the old stolen information Dr. Oz. But I’ll take my health information straight from the source: DR. BERG.

  • This was a great presentation, thanks for the upload I will watch it over again.

    Why can’t I comment on Individual comments?
    I think YouTube is blocking me.

    Maybe I’ve said something wrong.

  • What an amazing presentation. For me, as a non-academic (certainly non-scientific or medical), this made complete sense and was easy to understand the use of the slides to support / explain the findings was great (ok I DID have to pause a few of the slides to make sure I understood the graphical correlations).

    I hear some recent concerns about keto diet effects on the kidneys for diabetics. I’m Type 2 although moderating my diet so comfortably at pre-diabetic levels. Would be keen to hear if there has there been any new information since this presentation that might be relevant to diabetics.

  • I have a question, in ketosis we take most of the energy from the fat and insulin is low to start ketosis…fruits neither spike insulin and most of them ie 80% of fructose get stored in the liver and only 20% goes to muscle in the form of glucose…
    so actually both the criteria of ketosis is matched..so why cant we take fruits in ketosis please enlighten me

  • Its kinda of like a catalytic converter in a car’s exhaust burning off unused energy on exit of the system. It creates heat and blows it out with no gain to the system in mpg or future energy needs in the system. Except the car can’t decide to store it when exhaust system is malfunctioning.

  • Thank you, Professor Bikman! You have explained the complex metabolic reaction of our bodies to carbohydrates, protein, and fat so clearly that I think even a fairly uninformed person can understand the role of carbohydrates and insulin in fat deposition. I am going to point out your presentation to several type 2 diabetics who think I’m nuts for controlling my type 2 Diabetes strictly through diet—a diet greatly made up of—OH HORRORS—FAT!

  • Thank you.
    Once the weight loss settles…
    I’d like to know how we as individuals can identify when and if we are converting our white fat to brown fat and what are the visual indicators that prove we are doing this (apart from weight loss) especially once our weight loss subsides. Is it then the addition of exercise is required??? that will be the trigger for that exchange?

  • IMPORTANT QUESTION: The first study when they created hyperinsulenimia in the mouse, how was this accomplished? It showed a picture of a syringe. If this was not done through high glycemic food and rather through injection, then this study and this conclusion, is completely false and misleading. Please provide the link to the study, and explain how hyperinsulinemia was achieved. Scientists like to find data that suits their agenda. I hope that this is not the case in this video.

  • I have been cutting out the carbs to lower my A1C blood sugar level ( up to 5.7 )…..problem is I don’t want to lose anymore weight, as I am 5′ 11″ and 155 lbs ( I was 165 lbs 2 weeks ago )……what exactly should I be eating to maintain weight and still cut out the carbs…..thanks

  • Thank you for yet another clear and informative presentation.
    One question that remains is to understand to what point ketones themselves have an effect on the metabolic pathways and cellular inflammation and to what extent they are merely an index of the glucose shortage and the opening of the decarboxylation pathway.

    Do ketones have an anti-inflammatory effect or does the glucose shortage starve intracellular germs and viruses that produce inflammation?

    In so many ways, the valiant band of metabolic explorers you represent remind me of the feats of Livingston and Stanley discovering Africa.

  • Brilliant talk, chock full of scientific information which will take many views by this totally biomedicalignorant person to understand and absorb.

  • Get people on a keto diet and put them in a cold pool for 30 minutes a day. Do the same with people on a regular diet. Do that for a month and see if anything interesting falls out.

  • Just wondering: Energi waste of ketones in the breath and in the urin is OK. But what about the enrgi lost to heat? There are no substances in heat? E=mc2. Isnt heat just radiation? You cant loose weight just by heat? Is it that the “exhaust” from the heat-produced is CO2 from the cell and we breath that out as well?

  • Another question for anyone who knows their stuff:
    What is the adaptive theory for us “wasting” energy by urinating out “parts of fat”, ie ketones?
    It seems to me that would be highly selected against from an evolutionary/adaptive point of view.
    Is it just a biochemical necessity to get at the fat energy?

  • very well done Doc Bikman & thank you for talking about function, just another reason why i did not pass microbiology in juco college (twice) five star *****5*****especially at a time when the Wim Hoff method is being used & in your words may be “remarkably related”.

  • DR Bikman is an amazing presenter, objective, articulate. Not the least bit offensive or obnoxious like some. It is a pleasure to watch and listen.

  • I was wondering if on the flip side of this, can this endocrine theory account for why so many people say they feel cold when their insulin is high as a result of a high sugar diet?

  • Wow!! what an interesting interview. This is my first time watching your program, but not my last. Got a lot of information. Keep it up!

  • Rip off “Doctor” Oz took this info from genius Dr. Berg. Shame on you Oz. You owe Dr. Berg an apology and $$$. SHAME and couldn’t even deliver the message properly. You should have allowed Dr. Berg to present this vital info.

  • 3 Reasons Why Bulletproof Coffee is a Bad Idea and the dangers of long term on a ketogenic diet.
    Humans did NOT evolve eating (or drinking) such massive amounts of saturated fat.
    There are plenty of nutrients that are healthy when consumed in reasonable amounts, but when people start megadosing them it can cause serious problems.

    One example is fructose… it’s “good” when found in nutritious, fibrous whole fruit, but a disaster when consumed in massive amounts from refined sugars (6, 7).

    Another example is linoleic acid (the main Omega-6 fat)… it’s healthy when found in whole, nutritious nuts, but a disaster when consumed in massive amounts from veggie oils (8, 9, 10).

    It is entirely possible that saturated fat is the same. Healthy in reasonable amounts, but harmful when we start eating massive, unnaturally large doses that are way outside of evolutionary norms.There are plenty of nutrients that are healthy when consumed in reasonable amounts, but when people start “megadosing” them it can cause serious problems.

    There have been numerous reports of people having massive increases in cholesterol levels when drinking bulletproof coffee. This includes advanced risk factors like ApoB and LDL particle number.

    I personally think it is best to proceed with caution when adopting a drastic dietary change that has never been tested and is way outside of evolutionary norms. It is better to be safe than sorry.

    -Another trend a slow unhealthy liver cannot metabolize and process eating so much fat 7 days a week.
    ..sooner or later your liver it clogs up.

    ” ketogenic diet ” -In the study, the researchers fed mice a ketogenic diet for several days and expected to find a favorable outcome — perhaps weight loss or another indication of improved health. Instead, they found that the “liver began resisting” insulin” almost immediately and the mice were unable to regulate their blood sugar levels after only “three days” on the diet. (Insulin resistance, meaning that cells in the body don’t respond to insulin, is a key characteristic of type 2 diabetes.)�� Go to this website to read Article on keto diet.


    -Many people follow ketogenic diets for weight loss and other health benefits. A ketogenic diet can be an effective means to lose weight, reverse type 2 diabetes, fatty liver, and other health conditions.

    The problems come, however, when you follow a ketogenic diet for an “extended period”. We already know from the many children who have followed a ketogenic diet to suppress seizures that they are at least 10-fold greater risk for kidney stones, impaired growth, dysbiosis, and metabolic distortions.

    If you follow a ketogenic diet, you MUST address bowel flora, especially with prebiotic fibers. And you would be well advised to not remain ketotic for extended periods else you are at substantial risk for dysbiosis, constipation, diverticular disease, and “colorectal cancer”.

    Great video to watch if you’re on a ketogenic diet ;


  • It can be so much more complicated than this. I have been carnivore since April 2018, and my serum iron kept tanking (ferritin was as low as 30; though a decade prior it was as low as 9, but has been up since then). I don’t have heavy periods, or GI problems. I eat mostly red meat. I was even taking heme iron supplements. I even tried them every other day. I had lost 10 lbs (to a healthy weight) when I first started carnivore, but then started slowly gaining. And I was TIRED. Thyroid panel kept improving. I learned from EONutrition that Riboflavin (B2) deficiency can cause you to not absorb iron. I started taking B-100, and BAM, iron, ferritin, hemoglobin, etc finally started going up. But I also GAINED 30 lbs. I stopped the iron supplements. Don’t really know what to do at this point and the weight just won’t budge.

  • Lamb is a good iron source. My Iron improved when I added lamb to my diet weekly, Moringa Supplement and a green smoothie every day.

  • i went to a Carnivore diet but kept eating Peanut Butter and found when I stopped eating Peanut Butter my iron levels increased dramatically. I was dealing with a lot of low levels on eating Keto and eating Peanut Butter. (Peanut Butter is so good by the way.) Lol

  • We’ve been living off carbs for so long that we think of the emergency energy source (glucose) is the normal source and the normal sources (fat and protein) are the backups.
    Glucose is a quick and dirty way to supply energy and to store up fat in times that fat and protein are scarce

  • I’m about 2 weeks into keto diet and I was thinking about the wasting part of the ketone diet as well. Have someone don the math on how many calories one would waste just by pissing and breathing out ketones?

  • If iron deficiency is found, lower energy, and troubles with weight loss, I would test full thyroid panel.
    Free T3
    Free T4
    Reverse T3
    Thyroid ultrasound as well

  • “Not personal advice if you want that please consult with your own physician” the sad thing that I am here because my own physician made my health worse. Of course I understand why he said it, but it is funny.

  • Fat cells are inherently inflammatory? Isn’t that a bit Catch 22 with his closing statement treat the inflammation and the weight will start to come off?

  • Loved it, this info has helped me already! Also interesting that once again we need to recognize the very real differences between male and female biology no matter how political activist try to deny them.

  • So interesting. I’ve had very low iron and im also struggling to loose weight doing keto. I’m now on iron tablets so fingers crossed the scale starts going down in the right direction

  • Dr. Paul Mason, as always, opens my eyes to different aspects of health that I previously never entertained. Thank you Dr. Mason for this enlightening presentation. I, like so many others, just ascribed the difficulty of women losing weight to hormonal differences, and women having less lean body mass than men. Despite being a voracious reader of books regarding nutrition and despite being an avid viewer of numerous lectures pertaining to health, I never encountered the central role of iron deficiency as an impediment to weight loss. This further highlights the importance of focusing on nutritional quality just as much as macronutrient ratios and calories. The fact that women have to combat so many obstacles to induce the same weight loss that men experience, just makes me respect women, who have achieved significant weight loss, that much more.

  • I have to ask since no one as yet has discovered why…I suffer from both very low ferritin levels, high inflammation and despite taking a high quantity (as prescribed) of ferrous fulmate twice daily, nothing changes. I haven’t been able to lose weight in years. I had put it down to a fairly inactive lifestyle due to requiring crutches to walk and because of repeated chest infections that have now put me on long term antibiotics.
    I also crave ice.
    Is there any tests I can suggest to my own doctors that might show something that has been missed so far?

  • I, as male, got anemic on a keto regimen high in chese, butter and veggies, worse even than my terrible vegan year, according to the lab test (and sluggishness). Plenty of red meat, few cheese and veggies, iron is ok and so the energy levels

  • But is antibiotics the only way to treat chronic inflammation? What if they can’t find what causes the inflammation? How would you proceed then? Just take a generic antibiotic to see if it works? I have this exact issue of high inflammatory markers very high CRP and PV but despite numerous blood tests to see where it stems from they couldn’t find a thing except a very slight elevation in anti-nuclear antibodies. My Drs say that I’m probably just someone whose normal range of these markers is a bit higher than the national average and nothing they can do about it. But I have the same problem of never being able to lose weight on keto and even on carnivore the weight loss is excruciatingly slow to negligible despite eating OMAD, red fatty meat, coffee/cream and water. It would be very interesting to know what people like me can do to combat this mysterious inflammation without the aid of Drs who are savvy about these things like Dr Mason. For now I’m sticking to carnivore as slow weight loss or not at least there is some movement downwards on the scale despite taking months before results are seen.

  • I totally agree. He looks ten years younger! I definitely look ten years younger when I am my skinniest and strongest too. Thank God for intermittent fasting. No more yo yo dieting.

  • I want a doctor like Dr Mason….. on this side of the planet. As doctors go he seems to be on an other planet….so relatively seen we are getting closer

  • Dr. fraudz…pfff Dr. Eric Berg was responsible for the information that Dr. Fraudz used and twisted giving people a false prescription for losing weight. Shame on this huckster.

  • Dr Bikman, You said we need insulin to make a fat cell from stem… can we kill (apoptosis) fat cells from staying in ketosis for prolonged periods? in essence starving them of their motivator? Thanks, Mike

  • More if this information please Paul. So very empowering. Just wondering if a portion of this information could be applicable to an 18 yo Male regarding parasitic infection etc and various elevated indicators/results?

  • Restless legs can be easily fixed with transdermal magnesium. There isn’t enough magnesium in the diet due to lots of stress. Magnesium is also the best anti-inflammatory.

  • Copper deficiency may be one of the many causes of fatigue and weakness. Copper is essential for absorbing iron from the gut. When copper levels are low, the body may absorb less iron. This can cause iron deficiency anemia, a condition in which the body is unable to carry enough oxygen to its tissues
