BMR or basal metabolic rate rises from birth to age five, then declines, then peaks in adolescence, and then drops during adulthood. This is because as we age, our body composition changes, and we lose muscle mass, which leads to a decrease in BMR. Regular exercise can help maintain muscle mass and increase BMR, but it does not continually rise throughout life.
