Weight loss loves company, hints new research.
For every additional 10 people signed up at a clinical center for a weight loss trial, the average person loses half a percent more weight, a study found.
Dr. Arne Astrup of the University of Copenhagen in Denmark and his colleagues delved into a database of 22 weight-loss centers across five countries. The researchers found that 10 more participants at a center translated into a modest half-percent climb in weight loss for the average person at that center.
