Extreme dieting practices can pose numerous risks, including nutritional deficiencies, loss of muscle mass, and potential metabolic disturbances. These restrictive diets may lead to psychological effects, such as obsession with food or body image issues. Additionally, rapid weight loss often results in a quick regain of weight once normal eating resumes, leading to a cycle of yo-yo dieting. Moreover, extreme restrictions can compromise overall health and lead to eating disorders, making balanced, sustainable approaches to nutrition paramount for long-term success.
