Why that last diet didn't work

". . . the International Association for the Study of Obesity recommends 60–90 minutes a day of moderate intensity exercise or about 35 minutes a day of vigorous activity for the prevention of weight regain following obesity. Although epidemiologic and laboratory data are limited, it appears that about 45–60 minutes a day of moderate activity is necessary to prevent the transition from normal weight to obesity, at least for a large part of the population." International Journal of Obesity, (2004) 28, 1541–1547.

Sigh. I guess exercise class 3 times a week and snacking on cheese and crackers while I blog isn't going to do it.
