A study aimed to determine whether the exercise guidelines established by the U.S. Surgeon General were sufficient to promote weight loss. The eight week study revealed that the group to achieve significant loss of fat mass was the group that exercised four times per week. The average weight loss was 13.3 lbs, and there was no difference between those of different ages or between men and women. This study suggests that exercise does not need to be difficult or overly intense to be effective. Despite the claims of various "experts," there is no secret to weight loss beyond that which we already know to be true.
