I was a skinny kid up until 5 grade, about 10. After going through a traumatic experience, I turned to food and started packing on the pounds. I was a good 30 lbs or so overweight throughout high school. Was very conscious of the fact that I needed to lose weight I was always on a "diet". Never a good one though and they didn't last very long. Very restrictive eating, very binge-y eating, very poor eating. I was like this till I got married at age 22. The second I was engaged I started piling on more pounds. I must have been one of the few brides who actually needed her dress taken out as it got closer to the wedding day. I had a baby about 19 months later and forget it - any semblance of normal eating was totally and completely gone. I became obese, then morbidly obese VERY quickly.
Then when I was 42, I'm 45 now, my light bulb moment came, realized that I didn't have to be fat if I didn't want to be. Realized that I did indeed have control over this (the whole time in fact) and made the decision to be a healthy person and lost 165 lbs.
