Dr Ludwig explained the INSULIN CARBOHYDRATE MODEL OF OBESITY. It made so much sense. All these chronic diseases and obesity are due to high insulin.
The body makes the hormone insulin when we eat carbohydrate. That is sugars and starches. The white stuff in our foods. Insulin is pretty much the fat fertiliser. It loves to store fat away and does not let the fat out. Just like the turnstile at the swimming pool.
