Kathy,
Not to be rude but I must post this. I am 5′ tall & 90 lbs. NOT anorexic or druggie. It’s called genetics. Same as obesity. I’ve tried everything from protein shakes & weight gain powders, etc…no help. So please don’t put all thin people into that category just because they are thin. They hate it just as much as a person who is obese. Thanks :)
