The more severely girls diet, the more likely they are to drink frequently and heavily, as well as to use marijuana and other illicit drugs Adolescent girls who engage in dieting have a 324% greater risk for obesity than those who do not diet (Stice et al., 1999). 95% of all dieters will regain their lost weight in 15 years (Grodstein, 1996). 35% of "normal dieters" progress to pathological dieting. Of those, 20-25% progress to partial or full-syndrome eating disorders. (Shisslak & Crago, 1995).
