I agree with you about the annoying double standard on TV and in real life. Overweight guys are everywhere on sitcoms but even slightly overweight women are rarely seen. And when you do see them they are usually loud, obnoxious women like Roseanne was.
Most of the guys in my family have very high metabolism and dont have to put much effort at all into staying in a normal weight range..all they have to do is stop drinkin beer and they lose like 20 lbs. Whereas most of the woman have to work obsessivly hard to stay in a so called 'normal' weight range for their height. Also unfair :(.
