Extreme dieting can pose several health risks, including nutritional deficiencies, metabolic disturbances, and psychological issues. Severely restricted caloric intake can lead to deficiencies in essential vitamins and minerals, affecting bodily functions. Rapid weight loss can result in muscle loss instead of fat, slowed metabolism, and potential heart complications. Additionally, extreme dieting may promote unhealthy relationships with food and body image, leading to eating disorders. Sustaining balanced, moderate diets paired with regular activity is essential for lasting health and well-being.
