    this guy is full of shit. If I see this guy on the street I would punch him in the face. Need to make this guys shut up somehow. You can easily tell he is full of shit just from the way he speaks how he doesnt present any data or even present any science. Anything he says is not supported by any evidence in the peer reviewed literature. he is straight lying his butts off and spewing pseudo science. What a piece of shit human being.

    Here's biochem 101, doc. Fat in tissues made of triglycerides (glycerol and 3 fatty acids ). Fat cells have receptors to Insulin that activates nutrients uptake. Fat cells are UNIQUE from other tissues in the sense that they cannot use glycerol from nutrients. The only way to make glycerol is via Glycolysis (sugar metabolism) in the alternative pathway when Glcolysis is redirected in the pathway of making DAG (diacylglycerol) etc.. Hence the only way for fat cell to make fat ( assemble glycerol with 3 fatty acids ) is in the state of excess glucose.
    Now, he's talking about type 2 diabetes. If you look at type I diabetes, those patients are skinny. In fact Diabetus Melitus means "sweet emacation". Ancients would notice that diabetics type I would be loosing fat and muscle mass while excessively peeing; since the old way of diagnosing it was actually tasting the urine and noticing it being sweet – hence the word Melitus = sweet.

    This is totally confusing. Beef spikes insulin more than white potato? Really??

    Beef comprises protein and fat, no carbs. White potato mostly carbs.

    Is this doctor saying that protein and fat spikes insulin more than carbs?

    Please someone answer this question!

    dec 19, 2016, High intake of carbohydrates leads to fat storage like fat intake leads to fat storage, the aim is to not to get fat because then the fats gets inside the muscle cells, less calories per day creates more sense as more calories in any way fats or carbohydrates lead to being fat and hence fats inside the muscles leading to insulin resistance,

    I was on Keto diet for 6 months, never lost weight, my blood panels worsened and I ended up in the hospital for 3 days with HBP spikes of 230/100. All that fat entered my cells and made me insulin resistant. I have been vegan for 6 weeks now, lost 10 lbs, feel great, BP is 110/68 (in that ball park), my diabetes is better (not cured yet) and I'm taking 10 less units a night, hopefully hoping to cure diabetes. I weight 169 currently, 5 foot 3 woman, age 58 and have been horribly sick with diabetes for over 7 years. I excercise, to stay limber, but realize that I can NOT burn the calories of a meat eating diet (high calories) so I have gone vegan. Not everyone's metabolism or body reacts the same to diets, life style changes. My father had coronary heart disease (as all his relatives, most died early, very barrel bellied fat, diabetic people), he had 3 bipass's, pace maker, diabetic and overweight. Eventually the hospital visits killed him with Mrsa. If I could have turned him Vegan I would have tried, but he was a meat eating, high carb, x-alcoholic x-smoking fool, and he probably wouldn't have listened to me anyways. But I'm listening Dr. McDougal.

    Losing that last 12 pounds of fat seemed like difficult challenge until I tried the “fizy unique plan” (Google it). It was so simple to lose that unwanted fat once I got started!

    Maybe for diabetics type 2. Whom eat a lot of carbs ánd fat. Every type1 can debunk that eating meat needs more insulin than potatoes!
    Eat high fat OR high carb. But never together. That's the clue here. Eating almost none carbohydrates and lots of fat will improve insulin sensitivity dramatically.
    LCHF for type1's.

    I reversed my diabetes on low carb high fat. I am full and satisfied at the end of every meal. My blood pressure went down. I did my own testing on me and unless I have a unique genetic make up, it works for me. The first thing that when down was my visceral fat. I don't know who is sponsoring the studies he is reading but they are wrong. I lost 40 lb in 3 months. There is no fat spilling. The fat that is bad is the corn oil canola oil etc. fats from coconut oil, nuts, avocados, olive oil, grass fed butter is actually good for you. Sweden actually switched to this lifestyle because of the benefits. His information and research is outdated.

    Take a plant, strip it of all it's nutrients and fiber and concentrate the sugar or fat and then feed it to people and they will get sick. Why do people on a high fat diet loose weight? Because the majority of their caloric intake has no nutrition. Basically, you are starving yourself but yet you feel full. Your body has no choice but to use it's fat reserves. You loose weight and feel and look better and your health improves but is it really healthy long term? No.

    So, here's an honest question for everyone ! – My internal med doc uses the " Ideal Protein" diet, to get body into ketosis and drop 15 lbs or less per week. Its good for diabetics, uses food packets that are lo carb plus fish or meat protein.
    I try simulating that on my own. Its 8 oz of protein a day plus vegs, etc. Very low carb.
    But its easy to overeat protein- So I am seldom in the right ketosis range to lose quickly. This isn't ketoacidosis, which is dangerous.
    So, is there any way to get into ketosis by eating non low carb, like Dr Greger ? I dont think so.

    When I eat carbs, my blood sugar soars and stays up for hours.  However if I eat protein (meats) it brings my high sugar right back down.  How can carbs be good and meat bad for diabetes?

    Bunch of CRAP.
    Do not listen to this man if you have Diabetes or cholesterol problems.
    High CARB in your diet stimulates insulin production by pancreas, which in turn stimulate the glucose in high Carb diet to Lipoprotein synthesis in the live. Lipoproteins are the basic raw material for Low density Cholesterol,(bad Cholesterol) which deposits in your arteries and causes heart hand other vascular obstructive diseases.
    Diet with saturated fat and cholesterol as in meat and Eggs, only causes high density cholesterol (Good Cholesterol) to go up! contrary to what this man claims. Cholesterol and other lipids are also necessary for normal brain function and synthesis of various vital hormones in your body.
    Unfortunately youtube has become a vehicle for losers like Dr. Greger to run their mouth and spread their message any more, however convoluted it may be. It is up to us individually to discriminate the good ones from the bad as much as possible, before following any!

    Thank goodness for Dr. McDougall and Dr. Greger. They have had to fight the system and their peers for truth that should be shared with the world but is not because of the almighty dollar. I am so thankful for the "good guys" in the world who have the strength to do what is right.

    I actually looked up a bunch of studies to insulin index of foods. And no fucking way that any of they show that meat has a higher response than potatoes or rice… This guy is straight up lying. He keeps talking about how he bases his opinion on science, but even wikipedia labels him as a pseudoscientist fraud.
