Which condition is likely to raise BMR?

Which condition is likely to raise BMR?

• A. Fever
• B. Sleep
• C. Fasting
• D. Aging

Answer: (A)

Basal metabolic rate is the amount of energy the body uses at rest to maintain vital functions. When fever occurs, the body raises its temperature set point to fight infection, and lots of energy is spent to support the immune response and heat production. That extra metabolic activity increases the energy demanded by the body, raising BMR. In contrast, sleep lowers energy use, fasting signals the body to conserve energy and can lower BMR, and aging typically reduces lean body mass and overall metabolic rate. So fever is the condition that raises BMR.
