I agree that most diets that deprive one of a complete food group are not good, because the body needs the nutrients from all groups. Plus once the diet it kicked to
the curb, the weight
usually comes back.
There are 2 types of carbohydrates; the simple ones, that include things made from refined sugar, flour, white rice, etc. These carbs raise your blood sugar quickly, and if not burned off right away, will be stored as fat.
