I've been fat. (Really, really fat -- 475 pounds.) I'm not any more (down to 170.) I know what it's like to be ostracized and ridiculed, believe me. I don't believe there is a "stereotypical fat guy." We're all human and we all have different concerns, problems, priorities, and challenges. When I was at my highest weight, getting a little exercise wouldn't even have been possible, let alone a solution to my personal energy crisis. I was using a cane just to get up the steps to my house. Mockery and ridicule never solved anybody's problem. Ever.
