60 Minutes of Exercise a Day to Lose Weight

This week's JAMA article on exercise and weight gain was discouraging. It showed women needed to exercise over 60 minutes a day to lose weight. The rest of them gained weight. Worse it only worked for relatively thin women. Above a certain weight, exercise had no relationship to weight loss.

Of course, elite athletes exercise lots, and they are not very skinny -- except perhaps marathon runners. Most athletes are beefier than non-athletes. I know when I begin a weight lifting regime, that I gain weight  not lose weight.

Having said that, it was too bad that over eighty percent of subjects gained weight. It seem like weight control is too hard.

Nonetheless I will be up at 5:20 tomorrow to exercise.
