What Causes Type 2 Diabetes | Debunking the Keto Diet | Dr John McDougall | Mastering Diabetes

What causes type 2 diabetes? And why do you need to hear a debunking of the Keto diet? If you're living with type 2 diabetes and have been eating low-carb diets to help eliminate large spikes in blood sugar hoping to reduce the need for insulin, you would want to hear this.
Here's a conversation between Dr John McDougall and Mastering Diabetes for a straightforward answer as to what causes type 2 diabetes. As it turns out, buildup of toxic fat is the culprit. But how does too much body fat get someone there?
And somehow discussing fat as the culprit always leads to discussing how people choose their diets. Take Keto for example. People are so drawn to the Ketogenic diet because it allows the body to maintain glucose levels at a low but level. But Dr McDougall shows which part of the diet is problematic and more lies about the bad food people are taking in.
Here's the conversation:
How too much body fat causes type 2 diabetes
Human civilization throughout history has been powered by starch
The problem with Keto diet
The problem with dietary guidelines for Americans
John McDougall, MD, is a physician, speaker, and best-selling author who teaches the importance of a whole food, starch-based diet in order to halt, reverse and heal chronic disease.
Dr. McDougall is co-founder of the McDougall Program alongside his wife, Mary McDougall - the original whole-food plant-based vegan and creator of thousands of low fat, oil-free, vegan recipes.
The McDougall Program is a leading medical program that heals chronic illness through professional medical care, world-class education, and ongoing support for people transitioning to a starch-based lifestyle.

I became type 2 and I am not, nor ever have been fat. I’m 5 foot 4 and weigh between 110 and 115 pounds. But my fat consumption has always been high. Mostly potato chips etc. not cheese not animal products. But over time I gave up all those bad things and now I’m off meds.

Too fat for your own body not necessarily fat compared to others

[@donwinston]

People's notion of what being "fat" these days is warped. Almost everyone these days weigh significantly more than people did 75 or so years ago. If you have type 2 diabetes you are by definition "fat". But not everyone gets diabetes are the same level of 'fatness" because of genetic reasons.

Yes you do. It is impossible to get type 2 diabetes if your are fit. If you are fit you will never get fat in your liver and muscles. That is what causes insulin resistance and leads to diabetes. But not everyone will get type 2 diabetes at the same level of "fatness". it varies according to genetics.

I like Dr. McDougal's soups, but have to ask why so much sodium? I choose the lower sodium versions, but they seem to be much higher sodium than necessary. It would be interesting to know why Dr. McDougal adds so much sodium to really good soups when salt is one thing that can be added if necessary. Very good programs.

[@JD-59]

It won't sell without salt. He has to add something appealing so people will try it, and salt is the least detrimental. I'm pretty that was his answer in an interview.

[@SP-fy4fx]

@@JD-59 Since you seem to be validly trying to respond to my question, let me explain. 1st and formost, I am not trying to get into a fight with you. While sales are a valid point for the all corporations bottom line, "people won't eat it" is a poor answer from a doctor trying to help people with T2D and the long term associated health problems. It is always good to re-evaluate a product and it seems good to pose to a test group if lowering the sodium content would truly dissuade sales. While extremely low sodium can hurt someone, most of us don't really know our daily intake of sodium is higher than we would expect. I noticed many of the people who commented said he really didn't answer the questions.

[@JD-59]

@@SP-fy4fx True. He could run it through a taste test with groups of people to try and establish an ideal sodium level for palatability. Dr. M seems to have a message that doesn't change much. So he often sound like he is repeating himself when he is being interviewed. Also Dr. M seems to me to be a "big picture " guy and doesn't focus too much on the small details like Cyrus might (e.g. intramyocellullar lipid in the inner surface of cells causing dysfunction to insulin signaling cascade). It would have been nice if he answered their specific questions. Maybe he is a broken record, but his message is a helpful one in the big picture. (But he does still read newly published research).

[@trotskyite1]

He doesn't own the soups and when they lowered the salt nobody bought them. Nobody died from 1 McDougall soup in their diet so it doesn't matter. Don't focus on the small beer

Salt will increase your blood pressure but it is not really the "cause" of high blood pressure. Similar to sugar raising your blood sugar levels but is not really directly the "cause" of diabetes.

This is balogna how do you explain skinny type 2 diabetics our metabolism is not much different than our hunter gatherer ancesters. We were never meant to consume the amount of carbohydrates that are available today and certainly not meant to produce the amount of insulin thats required by this over consumption of these carbs

[@denniscoen8175]

Well, hunter gatherers lived an active lifestyle that literally burned through fat, carbs, protein like a outdoor fire pit. It makes sense to eat potatoes and other carbs to stay satisfied and it doesn't move. I am sure they consumed meat too, but there is no way it was consumed the way it's consumed these days, as in in daily. If you try to be a hunter gatherer for a week, then you will quickly realize how difficult it's to find animals to kill, grow, skin, prepare in the wild and not to get sick.

[@dj-fe4ck]

In your opinion, which of these two diets is healthier? 1. A whole foods plant based diet, but about 5% of the diet is fish or lean poultry, and the diet is 5-15% calories from total fat and 1-3% calories from saturated fat, or 2. A whole foods 100% vegan diet, but 30-60% of the calories come from fat?

[@SP-fy4fx]

dj121: Dr. Michael Greger has a great book How Not To Die. Good advice. My husband went vegan 4 years ago, it is not an easy diet. I don't think many healthy diets recommend 60% calories from fat though. And while McDougall's website recommends margarine, it is all processed chemicals. Both Greger and Dr. Joel Furhman have been on Mastering Diabetes seminars. You might want to join some Facebook vegan groups as many have good advice (which is not necessarily me).

[@donwinston]

Number 1. Fat is fat. it doesn't matter if it comes from a plant although plants tend to have less saturated fat they still have some. Palm oil and coconut oil are almost all saturated fat.

If the message is really as simple as you can fix diabetes by reducing body fat by elimination of food poisons of animal foods and oils, then why does McDougall and you guys caution against consuming too much white sugar even though it was even said in this video that white sugar boosts insulin sensitivity? Your simple message becomes clouded when you both praise white sugar for insulin sensitivity but caution its consumption. Why not add tablespoons of white sugar to cereal, pastas, fruits and smoothies to enhance their sweetness?

[@megavegan5791]

They are not promoting or encouraging the consumption of white sugar. They are trying to emphasize the point that sugar is not the demon when it comes to T2D. It’s the over-consumption of calories with too much saturated fat that causes T2D. Pure sugar over-consumption presents its own set of problems.
