I'm 13 and I'm about 140 lbs. I always eat a good breakfast, a snack in between breakfast and lunch, a small lunch, again a small dinner, and sometimes a light dessert. I really am not too hungry so I don't eat a lot.
I'm on a track team and we practice 5 days a week for an hour (occasionally an hour and a half). We run about three miles every day. I did cheer in the fall/ winter, and I was probably the strongest base. We only practiced 3 times a week and I ended up gaining about 15 lbs since then! I don't get it!
Can anyone advise?
