The Carbohydrate Addict's Diet works by restricting carbs enough to curb carb cravings, but not so much as to totally eliminate a dieter's favorite foods. This diet is based on the concept that weight gain is mainly caused by cravings for foods high in carbohydrates. Therefore, a majority of the foods on this plan are low in carbohydrates and high in protein.
According to HowStuffWorks, the creators of the plan, Dr. Richard Heller and Rachael Heller, believe that eating too many carb-rich foods causes a spike in insulin production, which triggers cravings for more carbs. Their diet is designed to address this problem by having dieters eat two meals a day consisting of low-carb foods. No sugar is allowed. The third meal is called the reward meal. This meal consists of one-third carb foods, one-third protein foods and one-third no starch vegetables. As long as this formula is followed, a dieter can eat anything he or she wants for the reward meal.
Some people seeking an alternative to the Atkins diet find it easier to stick with the Carbohydrate Addicts's Diet. Older adults should approach this diet plan with caution. The high protein levels in this diet may cause kidney difficulties. HowStuffWorks notes that experts find no linkage between insulin levels and weight loss.
