Final answer:
A series of diets followed by weight regain is known as weight cycling, often due to unsustainable fad diets. An eating disorder involving binge eating and compensatory behavior is bulimia nervosa. Sustainable weight management involves balanced eating and exercise to avoid unhealthy weight cycling.
Step-by-step explanation:
A series of diets followed by eventual weight gain is referred to as weight cycling, which is often the result of fad diets that are restrictive and not sustainable in the long term. Instead of these diets, health experts recommend adopting a healthied lifestyle with balanced eating and regular physical activity. One of the eating disorders characterized by episodes of binge eating followed by attempts to compensate for the excessive amount of food consumed is known as bulimia nervosa.
Weight loss and weight gain are influenced by a variety of factors, including genetics, metabolism, diet, and physical activity levels. Successful long-term weight management involves making lifestyle changes that include mindful eating and exercise rather than following fad diets that promise rapid weight loss, which can lead to a cycle of losing and regaining weight. This yo-yo dieting is less healthy than maintaining a stable weight.
