Hii you guys I've never really had much of a appetite like I really only eat sweets lol. I'm 84 pounds and I'm 13 and I always lose weight like 2 pounds really like every so often maybe because I swim and I'm cheerleader but I really want to know why. I can really not eat for a day and not be starving also a pop tart can get me full so I was thinking maybe my stomach is too small because I know the stomach is inside your body. Thanks you guys.
