Examples of eating disorders are bulimia, binge eating, anorexia, malnourishment.
The "War on Obesity" is a campaign to bring attention to the fact that people eat too much. Doctors and nutritionists are trying to educate the public about the dangers of overeating. They are very serious about it, hence, and have delared "War" on Obesity.
But . . . there is the concern that if people think that they are eating too much, they may cut down on eating correctly. They will not get the proper nutrition. There is special concern about teens, who don't eat right anyway. They tend to eat a diet of junk food. If they cut back on that, then they will be eating little amounts of the wrong things. This will be a health issue in the future.
