Weight cycling, also known as the “yo-yo effect,” refers to the process of repeatedly losing and regaining weight. This pattern is common in individuals who engage in restrictive diets or extreme weight-loss methods. Each cycle can negatively affect the body’s metabolism by slowing it down, reducing muscle mass, and making it harder to lose weight in the future. Additionally, frequent weight fluctuations can increase fat storage, particularly in the abdominal region, contributing to further weight gain over time. Psychologically, weight cycling can lead to frustration and unhealthy relationships with food. To avoid the negative effects of weight cycling, it is important to adopt sustainable, gradual weight loss strategies that focus on long-term lifestyle changes, including balanced eating habits, regular exercise, and emotional support.
