Fad diets often present potential risks, as they tend to promote rapid weight loss without sustainable change. Such diets may lack essential nutrients, leading to deficiencies and adverse health effects in the long run. The restrictive nature of fad diets can result in a cycle of yo-yo dieting, causing emotional stress and negatively impacting one's relationship with food. Furthermore, they often promote unrealistic expectations for weight management. Sustainable weight loss is best achieved through balanced nutrition, regular physical activity, and healthy lifestyle choices rather than through extreme diets that provide short-term results.
