A team of researchers in the US is set to use Apple iPhone and Watch to track binge eating disorder among people. According to University of North Carolina's Center of Excellence for Eating Disorders, if you are 18, have an iPhone (model 5 or newer), and have a current or lifetime experience with binge eating disorder (BED) or bulimia nervosa (BN), you can participate in the study titled "Binge Eating Genetics Initiative" (BEGIN).

"The goal of the BEGIN study is to better understand the genetic factors that may be associated with binge-eating disorder and bulimia nervosa in order to develop better treatments for the millions of people who suffer from these illnesses," the university said on its website.
