Lifestyle choices profoundly affect metabolic rate, influencing how efficiently the body burns calories. Factors such as diet, physical activity level, and sleep patterns play critical roles. Consuming a balanced diet rich in protein can increase the thermic effect of food, while regular exercise helps build muscle mass, which is metabolically active tissue. Conversely, sedentary behavior and inadequate sleep can lower metabolic rates and contribute to weight gain. Adopting healthier lifestyle choices can enhance metabolic function, supporting weight management and overall health.
