Husband and wife, Dr. Michael Eades and Dr. Mary Dan Eades, are among the world’s most knowledgeable doctors on diets and disease.
They are popular bloggers, have written multiple books on the subject and are best known for their Protein Power series of books.
They also have decades of experience treating patients with obesity, diabetes and the metabolic syndrome.
In the interview above, they explain how calorie restricted low-fat, high-carb diets usually don’t deliver very good results for people.
Carbs, Insulin and The Failure of Low Fat Diets
“People who are, through force of will, able to stick to a low-calorie, low-fat diet are miserable most of the time because they’re hungry all the time.”
A meal high in carbs but low in fat and protein gets absorbed rapidly and induces an insulin spike, which makes fat cells hold on to and store fat.
Because low-fat diets are usually calorie restricted, they don’t pack enough bulk to induce satiety. They also start a blood sugar roller coaster that leads to a cycle of hunger and snacking on high-carb foods.
There is no carbohydrate that the body can’t efficiently produce on its own. The same does not apply to protein and certain fats, which are both absolutely required in the diet.
It doesn’t really make much sense to make this non-essential macronutrient the dominant part of the diet, especially when you consider that high-carb foods like sugars and grains are nutritionally inferior to animal foods.
