What are the effects of long-term calorie restriction on metabolism?
Long-term calorie restriction can significantly affect metabolism by slowing down the body’s energy expenditure and altering hormonal balance. When the body consistently receives fewer calories than it requires, it adapts by lowering basal metabolic rate (BMR) to conserve energy. This metabolic slowdown can make weight management more challenging and may lead to loss of lean muscle mass. Additionally, prolonged calorie restriction can disrupt hormones that regulate appetite and metabolism, potentially leading to increased hunger and fat storage once normal eating resumes. Therefore, a balanced approach to nutrition, rather than severe restriction, is advisable for sustainable health.
