Extreme caloric restriction poses several risks, including nutrient deficiencies, decreased metabolic rate, and loss of muscle mass. Such restrictive diets can lead to fatigue, diminished physical performance, and increased irritability due to low energy availability. Extreme caloric restriction also triggers metabolic adaptations that make weight loss more difficult in the long term. Furthermore, this approach can result in binge eating or disordered eating patterns, negatively impacting mental health and overall well-being. It is crucial to adopt balanced dietary strategies that provide adequate nutrition to support healthy weight management and physical activity.
