That’s sad. However, if you ever did get to see my daughter’s muscle mass, that thought would never occur to you.
Biggirl, when all of us on the team would go out to eat after a game or tourney, I’m sure the waitresses were cringing at the amount of food we consumed.
From what I understand, there aren’t too many bulemic atheletes. If they were, they wouldn’t be an athelete for long because the muscle needs the energy from the food.
She sounds like she’s just incredibly active, and yes, I’m jealous 
Biggirl, I could have nearly written that OP about my sister!
Just before she turned 13, we went out to dinner for her birthday. She ordered fried mozzarella sticks (and wouldn’t share!) plus dinner: steak, baked potato and all that accompanies that - soup, salad, bread, veggies, soda pop. Then she proceeded to finish Mom’s onion rings AND half her steak, Dad’s baked potato AND his salad, and about a third of my pasta. Then she ordered some ghastly thing called a “chocolate chip explosion” - a thick chocolate chip cookie in a FRYING PAN, covered with ice cream, hot fudge, whipped cream, more chocolate chips and a cherry. We estimate she ate a full three pounds of food that evening. We got home, and she opened the fridge and said, “Aw, man… are we out of milk?” Mom said, “Oh, yes, I forgot! Have a glass of juice or something.” Sis said, “No, I wanted a bowl of cereal.”
At the time, she weighed roughly 75 pounds, and was a tiny little thing. About six months later, she hit puberty with a passion and finally gained some weight.
Before I managed to ever gain some weight from my own food intake, 20, yes, twenty Taco Bell tacos were required to make a dent. Recently, I managed 18 of the suckers. I suppose I should go for the 20 again, just for grins. I once ate 23 Æbleskiver (Danish doughnut holes) just to prove a point (a still standing family record)!
My friends are always astonished when anyone else at the table finishes their food ahead of me. It’s usually because I’m engrossed in the conversation, but no one else is ready to admit that.
I still eat whatever the hell I want and don’t gain weight. My mother was the same up until her early 40s. If genetics have anything to say I’ll still be 140-150 when I’m 40.
However, the days of eating 3 full plates of pasta for lunch and then another few plates of whatever for dinner are gone (painfully skinny as a freshman in high school playing football. No, I did not have a death wish. Nobody thought I could last the term without being killed. Showed them.)
OK, who else has that Wings song in their head after reading the thread title?
And it’s not spelled “soccor”, Biggirl. It’s “football”. 
Back in the old days at Tijuana Joe’s Mexican restaurant in Bezerkeley, I would usually order first and the young waitress would then ask;
“Is that for the whole table or just you?”
I’m a typical American-- can’t even spell it right. But if my daughter and her freinds are anything to go by, soccer is catching on like wildfire with young girls. Well, maybe not wildfire. Sorta more like a cold or something.
