Types of Fad Diets
*Cutting out one macronutrient: Low-fat and low-carb diets are basically low-calorie diets since the major macronutrients: protein, fat, and carbohydrate are just different forms of calories. Naturally cutting out a macronutrient will cut down calories and lead to weight loss. However, the best way to lose weight is to merely have a good balance of calories with about 50% calories from carbohydrate, 30% from fat, and 20% from protein.
*Eating a very small variety of foods: Diets composed of merely chicken breast, fish, salads, and grapefruit will get boring really fast, and are therefore not practical to stick to in the long term. Therefore, a good balance of lean proteins, dairy, and a variety of fruits, vegetables, and high-fiber whole grains will be more practical to maintain in the long-term and aid in weight loss and maintenance.
*Cheat day diet: Some diets promote eating whatever you want for one to two days a week and then eating “clean” for the rest of the week. This inconsistency in eating and allowing a whole day of uninhibited binging of unhealthy foods can promote unhealthy habits if using food as a reward. It is better to eat a balanced diet every day and allow yourself 100-200 indiscretionary calories a day of your favorite treat to allow consistency and establish overall healthy habits.
*Liquid diets: Although potentially beneficial in the short-term to relax the digestive system, liquid diets in the long-term can get tiresome and therefore are impractical to maintain in the long-term. Fibers from fruits, vegetables, whole-grain products and protein from beans, soy, and animal products are beneficial for proper digestion.
