In general, muscle gain is likely to relatively increase basal metabolism, but the increase is limited. Basal metabolism is the most basic energy consumption to maintain the body’s vital activities. Factors affecting basal metabolism include body weight, height, body surface area, disease, temperature, medication, and so on. Human muscle tissue is metabolically active tissue, if the body’s muscle content increases, then the basal metabolism is indeed a relative increase. However, the value of basal metabolism that can be raised by increasing muscle mass will not be very high. Therefore, for ordinary people do not need to deliberately build muscle to increase basal metabolism, because basal metabolism will not increase a lot because of the increase in muscle content. In daily life, ordinary people should maintain a healthy diet and follow a scientific and healthy exercise can be.
