Narrator: This is Science Today. A recent study of human energy expenditure confirms what many women already know: women spend more time on household and childcare activities than men. Gladys Block, a professor at the University of California, Berkeley's School of Public Health says that while men and women expend roughly the same amount of total energy, they expend energy in very different ways.
Block: In terms of per pound of body weight, men and women are pretty similar. Other studies have found because other studies have tended to focus on vigorous physical activities and leisure time physical activities and it turns out that men spend more of their time on that and women spend more of their time on household activities.
Narrator: The study, conducted by Block, collected minute-by-minute information on the daily activities of over seven thousand Americans in a 24-hour period.
Block: So - got up and brushed my teeth, five minutes. Got dressed, ten minutes - like that all the way through the whole day. So using that information, we can actually figure out energy expenditure.
