In the above mentioned study, the four levels of exercise studied was 0-199, 200-599, 600-1499 and >1500 calories per week. In those with a BMI under 25, the greatest benefit was in the 200-599 groups and the 600-1499. All activity was better than no activity but to much activity (>1500) was not better.

Also, the benefit of exercise decreased as the level of BMI decreased. The benefit of exercise for the obese in this study was a 26% reduction in risk. For those who were overweight there was a 18% reduction in risk. For those with a BMI below 25 the risk reduction attributable to exercise was 7%. One can assume that this risk would be then even lower in those at the lower end of the "healthy" range of BMI (18.5 to 22)
