Teenage is a time of great changes. It is normal for adolescents to be overly conscious of their body image. But perceptions of body type—overweight or underweight—tend to produce negative body image, affecting self-confidence self-esteem. When we hear of “going on a diet,” we usually think of reducing meal sizes or eating differently, to try to lose weight. This makes food an enemy. Many don’t understand that if they loose weight rapidly via fad diets, they also put their life at risk. Drastic calorie reduction makes one lose weight by burning essential muscles and tissues. And also entails water loss. So, avoid crash diets.
