In teaching kids to eat healthy, it might also teach them that being fat is ugly, and you should be ashamed of yourself if you are. It also implies that the main reason to eat healthfully is so you can look good. When teaching healthy eating Dr. Brown suggests parents focus on keeping your body healthy so it can do amazing things. Weight should not enter into it. Parents should not limit how much their kids eat, but should allow them as much healthy food as they like. Kids should never feel guilty or stressed about food. This often causes eating disorders.
