A study shows that exercise leads to successful weight loss, but you may have to work out harder and longer than you were told.
"By the end of the 24-month intervention, the women who managed to lose at least 10% of their starting body weight... — and keep it off — were exercising twice as long as health authorities typically recommend and expending more than twice as many calories through exercise as women who had no change in body weight. The biggest weight losers were active a full 68 minutes a day, five days a week (about 55 minutes a day more than they had been before the trial began), burning an extra 1,848 calories a week."
