Yo-yo dieting

Yo-yo dieting, also known as weight cycling, is a term coined by Kelly D. Brownell at Yale University, in reference to the cyclical loss and gain of weight, resembling the up-down motion of a yo-yo. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again.

Causes

The primary cause of yo-yo dieting is the continual cycle of restrictive dieting and subsequent weight gain, as dieters often return to their old eating habits after dieting. This is often due to the fact that many popular diets are not sustainable in the long term. The body also has a natural tendency to maintain a certain weight level, known as the set point theory, which can make it difficult to lose weight and keep it off.

Health effects

The health effects of yo-yo dieting are a subject of ongoing medical research. Some studies suggest that yo-yo dieting can increase the risk of developing health problems such as heart disease, Type 2 diabetes, and high blood pressure. However, other studies have found no such links, and some suggest that weight cycling may be better than remaining at a high weight.

Psychological effects

Yo-yo dieting can also have psychological effects. The cycle of losing and gaining weight can lead to feelings of failure and low self-esteem, and can increase the risk of developing eating disorders.

Prevention

Prevention of yo-yo dieting primarily involves the adoption of a balanced, sustainable eating plan rather than short-term, restrictive diets. Regular physical activity and a supportive environment can also help maintain weight loss.
