The authors conclude that resting metabolic rate does decrease significantly in response to a diet of less than 1000 kilocalories per day, and that the addition of moderate intensity aerobic exercise (50–70% maximum aerobic capacity) performed for 31 to 60 minutes, 4 or 5 days per week, decreases this response, but does not return resting metabolic rate to baseline. Estimation of basal metabolic rate (BMR) and daily energy expenditure (DEE) in living humans and in fossil hominins can be used to understand the way populations adapt to different environmental and nutritional circumstances. Turning down the temperature in your home can subtly boost your metabolism. Age makes a difference because the body loses muscle mass with aging, which slows down metabolism. Reference: 1.
