One potential risk of extreme dieting is the development of nutritional deficiencies, which can lead to serious health issues. Severely restricting calorie intake and eliminating food groups may result in inadequate intake of essential vitamins, minerals, and macronutrients necessary for proper bodily function. This can lead to symptoms such as fatigue, weakened immunity, and muscle loss. Additionally, extreme dieting can negatively affect metabolism and lead to disordered eating patterns, which may have long-term psychological effects. Emphasizing a balanced, sustainable approach to nutrition is crucial for maintaining both physical health and emotional well-being.
