The repeated pattern of loss and regain of body weight?

The repeated pattern of loss and regain of body weight is known as "weight cycling" or "yo-yo dieting." This phenomenon typically occurs when individuals restrict their caloric intake to lose weight but then revert to old eating habits, leading to subsequent weight gain. This cycle can have negative effects on metabolism, physical health, and mental well-being, making it increasingly difficult to maintain a stable weight over time. Sustainable lifestyle changes, rather than extreme dieting, are often recommended to promote long-term weight management.
