Wow......i have been asking myself that for years. I started to gain weight in my teens.....like 15ish. At about 12/13 when i started to develop (D cup in grade 7 ) my Dad started to call me fat and lazy. I wish i was that "FAT" now! I have a 26 inch waist!!!! This went on for my whole teenage life at home, only it turned into stupid and what ever else he could think of. Needless to say i moved out ASAP. I think most of my 20's i had low self esteem and weighed from 170 up to 180......once again i wish i was that "FAT" now. Over the years i think i did a lot of work on myself worth and the relationship with my father and both have improved.......not perfect but improved.......I think the eating to cope became a habit.
