I never say anything when I see fat people with carb-laden carts, but I do feel sorry for them since that used to be me before I saw the light. I did get stares when I first went low carb and was stocking up on butter & fatty meats. Not that it is any of their business, but if you wore a t-shirt with your "before" picture on it, they could see that you lost 100 lbs eating like this!
