When I was 12-15 I would only eat once a day usually half a pack of m&m's and a coke at school until I got pregnant. Now I am 21 and eat once a day(dinner, I have meat, veggie and pasta). I weigh myself atleast 5 times a day. Are some ppl just like that or could I have some type of problem?
Yes, it sounds like you may have an eating disorder. Eating disorders are many different levels.
I used to be bulemic --lots of exlax, weight numerous times a day, two and three aerobics classes a day, all I thought of and did revolved around my weight, weight loss and staying thin. I was fat before and now, two kids later need to loose about 75lbs to be at a healthy weight. But I wasn't healthy then either.
