Why Fat Doesn't Make you Fat 

I used to be an avid low-fat supporter and for years would eat all the low fat products in the aisle, worked out a lot and I counted calories. It was all fine until one day I crashed and I suffered for months on end with tiredness, fatigue, headaches, etc. I was so lost. Then I switched to Paleo and upped my fat intake. It wasn't magic, but week in and week out I started noticing improvement and the momentum was picked up again. I was so scared that I would gain weight, but I actually remained steady and I was able to really cut down all my sugar cravings. Before I would constantly crave chocolates and sweet stuff. Now I hardly snack on anything other than a handful of nuts or some dark chocolate every now and then. Life is good. I believe we are hard wired genetically to respond to high fat diets. Our ancestors didnt pick the fat off the meat they could hunt, they ate it all and then some. They didn't have the same strain of wheat we have today and they certainly didn't eat products which are packaged in factories with chemicals unknown to our system. So on an evolutionary scale, we are in two states. Our bodies have not evolved much to accept all the "new" foods, but our technology and brains have progressed to this point. We just need to even out the playing field a little. I believe in Dr Mark Hyman, it worked for me.

I stopped eating carbs/processed sugar, and ate smaller meals throughout the day for 3 months and lost 30lbs. I didn’t even exercise.

I've been doing the high fat low carb diet and after a month of being on it i have lost weight, got my muscle tone back, have more energy, no more bloating and my metabolism is on fire even with my sad excuse of a workout plan. I still have a little fear of fats (of course because of what I've been taught my whole life) and of how slow meat is digested so i do pop a digestive enzyme with my meal as well to put my mind at ease.

14 people from the sugar industry disliked this video :P

I did a keto like diet for about a year straight and I took a good amount of supplements, including a good amount of distilled fish oil. I lost 50 lbs. I ate a lot of beef, pork, eggs and only low carb vegetables, under 20 grams of carbs a day for the first month, then after that I stayed under 100grams of carbs a day, but I allowed myself a cheat day once a week that I could have whatever I wanted, pizza, ice cream, etc. But I found that after a couple months I didn't want or crave a cheat day and then soon, I rarely used a cheat day. But, I also didn't feel guilty eating everything at dinners on Thanksgiving, Christmas, and any other special occasion. My brain was sharper and clearer. My blood tests were much, much better, absolutely everything fell into the normal range. My LDL was on the low side of normal, my HDL was on the high side of normal. Before Keto I had high LDL. I had more energy than I had in years. I didn't exercise at all in the beginning of the diet, but then, overtime, I had more energy and just started to be a lot more active, that made me feel better mentally too. I was just happier than I had been before. I have incorporated carbs back into my diet and I have not gained the weight back going on 3 years now. Plus, I have lost another 10 lbs. in the last 3 years, since I have been off the diet. However, I don't feel quite as good as I did on the diet, nor is my brain quite as sharp as it was on the diet. I believe that is because I allow myself to eat some sugar and bad carbs a couple times a week now.

I am so pleased all of this information is getting out there, and more medical providers are learning the truth and not allowing outside influences, person interests or just pure stubbornness cloud their judgement and advice anymore. I am anxious to get your new book.Thanks for all the work you do, really appreciate you bring this out here for so many of us to learn from.Shalom

1 Tablespoon of extra cold pressed unrefined organic olive oil every morning on a empty stomach.

I wish you would comment on Dr Michael Greger's videos on RU-vid. He claims such success with a vegan low fat diet and cites many studies and other successful doctors. Sometimes I don't know who to believe. I think the high fat, "normal" protein, complex carb makes the most sense. But then Dr Greger cites his research!

Thank you for suggesting Dr.Ludwig's book during your last video. My friend and I got the book and we are starting our high fat low carb plan this week. Thanks so much.

hi ,dr mark. i am not a medical student .but i learn a lot from your videos .thank you

Mark, what do you think about meat being as equally and/or close to insulinogenic as many carbohydrates?

Oops. Slip of the tongue or something else? Recommend whole foods *or* recommend oils and butter, but not both. Olives are a whole food. Olive oil is not. I'm from a "blue zone." There's much more to longevity than controlling weight. What good is being slender if you're dead?

Neck has a six pack. I’m all about colorize counting. I lost 40 pounds in 3 months. My girlfriend lost 50 pounds at the same time. Just do what works. I’m also an alcoholic and my sobriety has made this possible

Thank you for a great video! Coconut oil is a daily for me. and Avocado's are one of my absolute favourite. I also eat a couple of eggs a day especially when I'm working out. I feel as though included these healthy fats helps me so much with my sugar cravings.

Thank you sir! I heard about this it's like the keto diet.

So basically go on a ketogenic diet to lose weight? Wouldn't you lose muscle?

Thank you very much for this great video. I have one question : I don't understand why we can not get fat if we eat too much olive oil, or coconut oil. We have to, because they are triglycerides (coming from diatary fat) and they will be carried to our cells by "Chylomicrons" which are lipoproteins responsible for carrying diatary triglycerides. I agree that there will not be insulin secration, but chylomicrons will carry them directly to the cells and push them inside. Am I correct ? Therefore I am confused. Thank you very much for your answer.

best advice I've gotten so far by any book, doctor, speaker, research data, ect.......EAT FOOD, NOT TOO MUCH, MOSTLY PLANTS.

I heard people saying consuming fat can improve your skin. I think this is true.

Dr. Hyman... A fitting name for a Gynecologist, no?

I went on a zero fat diet just for shiggles. I had no energy and didn't want to get off the couch. I'd probaby gain weight if anything.

Where are the pictures and animations to spice up the viewing process?

I hate when people break down food into the macro-nutrients, they tend to ignore the micro-nutrients. Macros don't matter as long as you eat enough high nutrient foods. Even in this video you are clumping foods into macros vs identifying the food. In other words, oreo cookies and apples are both carbs but they do not have the same nutrient profile.

Also, doesn't the body prefer to store glucose in the form of glycogen through gylcogenesis rather than as adipose tissue through de novo lipogensis? Perhaps individuals who are eating certain types of foods (refined sugars, excessive meat consumption, etc) are having over active DNL, therefor storing carbs that would normally be stored as glycogen in the form of triglycerides instead?

I have been under the impression the only fuel source for the brain is glucose. How does restricting carb intake affect the brain's functioning? Wouldn't it bet the best to eat a balanced diet with a good amount of complex carbs as well as healthy fats?

Low carb MORE fat diet is the best, i lost 2,5 pounds in just one week without exercising, i try for many years with low fat,with bread,corn,rice,potato,little vegetables,with fruits like bananas and apples and 5-8 glasses of water, walking for miles,liffting weights at home and i didnt lost almost nothing, and when i lost a 2,3 pounds in no time and i mean in 1 month i was again back with almost identical weight when i was back in little fat with bread,some candies etc, i eat viber like flaxseeds,drinking lemon,apple vinegar,psyllium, and off course eggs,bacon,all meat,vegetables,grreek yougurt with avocado almond milk,water,spinach and celery smoothie, and i making muffins with eggs with little coconut flour and chedar cheese, and drinking water when i am thirsty, i i dont fear NO MORE cholesterol and fat!

What a quack. He's only telling half the story on almost every point, most likely to lead you to confuse you into buying his book. "It's not eating more and exercising less that makes you fat, it's being fat that makes you eat more and exercise less" No both statements were correct, it is a cycle. A cycle that starts with weight gain, which is caused by eating more calories than you burn. your genetics and diet play a role in determining how well your body can store this caloric excess, but you still have to have the caloric excess to gain weight. In other words you have to overeat to gain fat.

Dr. Hyman, you said Dairy makes you fat and you advised recently against it. But now you recommend butter, please explain. (only Dr. Hyman please) :)

Brilliant Videos, Thank you.

Long story short, I went low carb /IF and lost 33 lbs in 100 days! 💯💪

My dad used to work in a farm in a 3rd world country. He told me they fed the pigs avocados to fatten them up as quickly as possible. 🤨

Thank you so much for the info. But I encourage you not to do the same as everyone else, which is assuming that you're fat and want to lose weight. Faster metabolism is not a good thing for me, sorry. Just as a constructive criticism. 🙏

What about the people who eat vegan high carb very low fat (almost all fruits and veggies) and they are very lean. What happens, I am very confused about that.

So, now "they" are saying the red wine is BAD for us...........what say you, Dr Hyman?

I have a problem with a fatty liver, what can I do for my liver?

FYI: Fat is BEAUTIFUL just saying

High Carb Low Fat OR High Fat Low Carb. That is the trick, not that hard.

Hi Mark. I agree with your message that "fat doesn't make you fat", but for completely different reason. Our body need solvents to dissolve nutrients, to bring it to our cells, and remove waste products and other toxins from the body. We need water to deal with water soluble nutrients and toxins, and we need fat to take care of fat soluble nutrients and toxins. But if water leaves your body by itself, with urine or sweat, then FAT needs to be ABSORBED by non digestible raw fibre in your guts and then it will be REMOVED from your body with feces. So, If it sound so simple then WHY people do get fat? To answer this question simply answer to another question: Why body retains water? Most common reason is when people consume water soluble toxins FASTER than body can safely remove it. Body have limited capacity on toxins removing speed, and it just wait for the moment when you will stop consuming salt and other water soluble toxins, and give enough clean water to wash out already stored toxins. Same thing applies to fat soluble toxins. You have to stop consuming it, and then you should give your body enough SOLUTE to dissolve those toxins, and enough ABSORBENT to absorb it in your digestive tract. So, how do I know that this is true? I lost 20 kg in 6 weeks just by removing 3 things from my diet: MEAT, MILK and BREAD. (Meat and milk contains fat soluble toxins called OBESOGENS, and bread acts like a glue, sticking to walls of your digestive tracts and leading you to CONSTIPATION. You have to go to the toilet few times a day. Otherwise those fat will be reabsorbed back into your body.) I eat, till I was full, almost 3000 calories a day of cooked vegetarian food, with 50% raw vegetables. And I didn't exercise at all, because my leg was partly paralysed at that time. I was lying on the couch all day long, reading books. Now, 6 years later, I'm LFHC Raw Vegan and I still slim and I feel great.

Why am i here?

So hold on he is a functional doctor able to use the title of MD and dr yet doesn’t have a proper medical degree?? RU-vid should fact check medical professional degrees. A functional medicine doctor is not an actual doctor. Please clarify.

I lost 80 pounds in 6 months without exercise doing keto

What about complex carbohydrate? Such as oats, Brown rice and quinoa?

this guy looks like he is suffering from jaundice

what about all the vegan success-storys? they load up on carbs all day long and seem to do well. well, at least the ones on youtube.

this guy is wrong, fat does make you fat..

Why tf you giving them eggs and butter???loooooolllll ssshhhh nooooo

eat eggs hey? sure, why not. Periods for health!!

I Lurveedddd Etttt

thanks but i would need to veganised this

I've done the research using my own body as a test tube and contrary to all this new age wisdom, that fat does not make you fat, I quickly discovered that fat does indeed make you fat. I started Covert Bailey's "Fit or Fat Target Diet" on November 11, 1992 and followed it religiously for three months until February 11, 1993 and I dropped down from 208 pounds to 168 pounds for a loss of exactly 40 pounds.

every food has fat i am making pasta with tomato paste no salt added my meal has 5 grams of fat and near to no saturated fat. i disagree with coconut oil all it has is high amounts of saturated fats and near to no nutrition and please reference some studies to prove your point.
