Men burn more calories while asleep than women
(HealthDayNews) -- Ever wonder why diets usually give men a higher daily calorie allowance than women?
It's not a matter of size, nor the amount of exercise. It's how people sleep.
Adjusted for lean body mass, when men and women do the same exercises for the same length of time, the total energy expenditures are about equal. But the American Journal of Physiology says men and women sleep very differently.
Men use about 11 percent more energy to sleep than women do, which accounts for most of the difference in total daily energy expenditure and where the extra calories go.
