Diet restriction will only harm the body

If the idea of diet crazes has withstood history,could this mean that they work?In the short term, the answer is often yes.Low-carbohydrate plans,like the popular Atkins or South Beach Diets,have an initial diuretic effect.Sodium is lost until the body can balance itself out,and temporary fluid weight loss may occur.With other high-protein diets,you might lose weight at first since by restricting your food choices,you are dropping your overall calorie intake.But your body then lowers its metabolic rate to adjust to the shift,lessening the diet's effect over time and resulting in a quick reversal if the diet is abandoned.
