Sainsbury diet was introduced by Amanda Sainsbury-Salis, PhD. Sainsbury diet is a lifestyle diet, so the usual calorie-restricted diet is considered not that effective. In Sainsbury diet, an individual is allowed to eat something whenever he feels hungry as long as he eats only the amount of food enough to satisfy the hunger. Sainsbury believed that if a person will limit the amount and frequency of food intake, or if he will delay his meal, the metabolism will also slow down. She also recommends eating fruits and vegetables instead of processed or instant foods.
