Why Most Diets Don't Succeed Diets often lead to weight cycling (repeatedly losing and then gaining back weight). Yo-yo dieting refers to following a series of diets and gaining back the weight lost on each. Rigid diets are restrictive, unpleasant, and discouraging. Flexible diets tend to be more effective and better at encouraging changes in long-term eating habits. Our bodies produce powerful appetite stimulants. Most diet products and plans are ineffective. © 2015 Pearson Education, Inc.
