I'm afraid I'm guilty of this too. Perhaps because I've always been on the slim side- downright skinny as a kid, so I'm more comfortable with people more like me. And while it's true some people are genetically predisposed to be fat, for most it's behavioral- people just eat too much! Look at today's menus- "Big Macs", "Quarter Pounders","Whoppers", "Big Gulps"- and the standard 1960 hamburger is now only for kids. Well all those extra calories have to go somewhere. . . . . .
