What are the disadvantages of the overweight and underweight?

For overweight there are not that many disadvantages compared to underweight, however obese has much worse things then overweight, but being underweight is very bad compared to obese. Overweight simply points out you are either a little stronger then others and you probably are fat, or just fatter then most kids your age. Underweight means you have too little fat, and one major result is getting cold very fast. Obese simply makes it official-your fat, and your activity in this area would most likely not be too high.

I know there is much more to this, you will have to search wikianswers for more on obese, overweight, and underweight :(
