There are different types of diets that work for different types of people. Part of this is due to how one's body responds and the other part is due to a less physiological and more psychological aspect. The physiological nature is often controlled by insulin, which at the most basic level, is a storage hormone. In general, the lower the body fat you have, the better your sensitivity to insulin. Which means you can eat more carbs. While insulin is important for weight loss and overall health, it is not a black-and-white situation.
you cannot be assumed that diets high in carbohydrates are bad, just as you cannot be assumed that diets high in protein or fat are bad. There are different types of diets that work for different types of people.
