Is weight loss "contagious" ? According to a new study published online in the journal Obesity, teammates in a team-based weight loss competition significantly influenced each other's weight loss, suggesting that shedding pounds can have a ripple effect.

The study carried out by Ivan Norscia and Elisabetta Palagi of the University of Pisa (Natural History Museum) and Cnr-Istc of Rome, provides the first behavioural evidence that yawn infectiveness can be a form of emotional contagion.
