Studies have shown that that teens whose parents talked to them about food with a focus on their weight or size (for example, telling them that they shouldn't eat certain foods because they would get fat) were more likely to go on extreme diets or exhibit eating-disordered behavior such as fasting, using laxatives, or binge eating.
