If he/she is obese there probably eating to much. Meaning their nutrition isn't very good. Stunted growth, or if someone has tall parents, but their short. Their nutrition might be to low, or their mal-nourished. (here's an example of stunted growth. I have celiac disease [meaning I'm gluten free] but I have had so much wheat that my body was responding in a way where I wasn't getting enough nutrition, therefore making me short.). If someone is fit, they probably have a good nutrition intake. If someone is about average height, their probably eating healthy.
