I'm 22 yrs old born naturally skinny and 5.00ft tall and I use weigh 85 pounds at 10 but continued to slowly ?

well, running is the way i lost a good amount of weight within a month and a half, but i also did a pilates workout from a dvd. i went from 135 to 110 that way, then a few months later i went from 110 to 95 by becoming a vegitarian lol.
