A common way to boost metabolism is through increased physical activity, particularly strength training and high-intensity interval training (HIIT). Engaging in regular exercise stimulates muscle growth, which in turn elevates metabolic rate as muscle tissue requires more energy to maintain. Additionally, incorporating more protein-rich foods into the diet can increase the thermic effect of food, subsequently boosting metabolism. Staying adequately hydrated and ensuring sufficient sleep are also vital for maintaining an optimal metabolic rate.
