"Not everyone who is overweight is a food junkie," advises Dr. Lawrence Cheskin, director of the Johns Hopkins Weight
Management Center, a 2-year-old program at Francis Scott Key Medical Center.
If a person weighs 40 percent more than the upper range of ideal body weights, he is considered moderately obese and an increased health risk, Dr. Cheskin says.
Not all overeaters binge, but many do. From 25 to 50 percent of overweight people binge, he says. A binge is considered the consumption of a large quantity of high-calorie foods "in a discrete time period."
