Is it false to be a proporsional person?

bloggie, i have nothing to do sooooo i post one topic about skinny person especially woman. don't you think a model MUST have a skinny body? is it wrong when they have a proporsional body? what they afraid of? honestly, i have a skinny body too but i try to make my body heavier. why they have much worried of they weight? why they can get anorexia or bulimia? can they just thank to god of what god gives to them? why we as people never satisfied of what we get? but the skinny woman always be the queen of the "woman world". they proud of themselves and foolishly the other woman try to be like "them"
