clipped from: commoneatingdisorders.com Binge eating is when a person eats a very large portion food and doesn’t purge it like a bulimic or anorexic. They also do not take any measures to burn the extra calories through exercising. Consequently, most binge eaters will gain weight very quickly, though it is possible to be a smaller size and have the condition, particularly if a person has a fast metabolism. Either way, the illness must be addressed because it puts a person at risk for diabetes, heart disease and other problems associated with eating poorly.
