Why don't fat people lose weight if they don't want to be made fun of?

i could see u never been fat or overweight...losing weight isnt as easy as you think most people that are over weight are depressed and want to change the way they look but they have no support or feel hopeless... one thing is that people that bully kids are insecure themselves...its more wrong of the people that bully than the person who eats all day.... the people that bully hurts others and the person who over eats only hurts themselves
