Basal metabolic rate is lowered by:

Question

Quizplus · Accepted Answer

Loss of lean body mass leads to a decrease in basal metabolic rate. This is because lean body mass contributes to a higher metabolic rate, and a loss of it would lower the overall rate. Stress or fever can also potentially lower basal metabolic rate, but it is not a consistent or predictable effect. High thyroid gland activity typically increases metabolic rate, so it would not lower it. An increase in lean body mass would actually lead to a higher basal metabolic rate, not a lower one. Loss of lean body mass can lead to a decrease in basal metabolic rate as muscle tissue requires more calories to maintain compared to fat tissue. Therefore, with the loss of muscle mass, the body requires fewer calories to maintain its basic physiological functions, leading to a decrease in basal metabolic rate.
