wow, i just found this topic.. well, i weigh 115, and i'm 5'3 (i no, i'm short, mustang and GPG pick on me bout it all the time) lol. i weight 105 befor track started, but after track i started to over eat, and i no run (w/ all my events) the mile, the half mile, and i tripple jump. we were eatin at a resturant and i couldn't decide what size of onion rings to get and i asked the waiter how big the portions were and my cousin said "she eats like a grown man!" and the waitress said "a large it is!" lol, i do eat a lot, but i'm SO active w/ 3 dance classe and track almost every day plus runnin on my own, plus weight lifting when i can, i can afford to (and the 10 pounds is muscle, my max bench is 100 lbs.. ) but i do believe that it's all the person... places like Mcdonalds don't help by puttin salt in all their food products, but it's the individual's fault for eating there (and if the person has a thyroid problem, y r they eating fast food if they can avoid it?)
