When we exercise may affect the amount of fat we burn during the workout. Obviously, this is a matter of when, not if. Researchers in Sweden and Denmark note in the journal PNAS that physical activity at different times of the day affect the body in different ways. In this study, using laboratory animals, the researchers studied fat cells after high intensity exercise at two different points of the daily cycle—an early active phase and an early rest phase, corresponding to late morning and late evening for humans. Physical activity at the early active phase appeared to boost metabolism and increase breakdown of fat independent of food intake. The right timing seems to be important for improving health benefits, but authors encourages more study.
