Decreased energy expenditure indicates:

Decreased energy expenditure indicates:

• A. Starvation
• B. Infection
• C. Hyperthyroidism
• D. Sepsis

Answer: (A)

Decreased energy expenditure happens when the body shifts into energy-conserving mode due to lack of caloric intake. In starvation, the basal metabolic rate lowers and the body reduces energy use for nonessential processes to preserve energy stores. In contrast, infection and sepsis raise energy expenditure because fever and immune activity increase metabolic demand, and hyperthyroidism boosts metabolism through excess thyroid hormones. So the state that best matches decreased energy expenditure is starvation.
