                                According to a study published in the *Journal of Nutrition*, long-term adherence to very low-calorie diets can lead to nutrient deficiencies. A 500-calorie meal book, however, is a guide or cookbook that provides recipes designed to be around 500 calories, often used as part of a medically supervised very low-calorie diet (VLCD) or an intermittent fasting plan.
