So on with it:
Science Daily reported on a University of Missouri study comparing Weight Watchers to gym membership weight loss programs.
While the WW participants lost about 5% body weight, this was mostly comprised of lean muscle mass. The gym participants, in contrast, did not lose much weight, but did lose significant amounts of intra-abdominal fat. While this makes the gym program sound more successful, they researchers also found that without support, the gym participants quit, while the support of meetings from WW kept it's participants in the program.
“These results imply that overweight, sedentary women joining a fitness center with the intent of weight loss or body fat change will likely fail without support and without altering their diets,” Ball said. “Nearly 50 percent of people who start an exercise program will quit within six months.”
“This study attempted to discover what takes place in the real world when overweight women attempt to lose weight.” Ball said. “I think the outcome of the study speaks volumes about the necessity for a multi-pronged approach in order to lose weight, body fat and gain health benefits. I hope that this will be the first in a series of studies investigating commercial weight-loss programs.”
