I was going to ask this as well. Is she having water after sprinting? I know the research says you don't "need" it then, but I find I'm thirsty after exercising. Definitely up her carbs as well. If you do a search, I'm sure Mark has written an article on it.

If you're concerned about it, have her drink some water and wait 20 minutes, but my bet is that she needs more food. Even if she isn't growing taller, she's still 1. developing and 2. growing muscles. That'll take a lot out of her.
So about 30g of carbs in the morning and 30g in the evening.

Please, do your teenage daughter a favor and don't allow or enable her to a severely restrictive diet like that. Teenagers need plenty of healthy carbs as well as good sourced dairy.
Girls at that age are susceptible to developing eating disorders.
Also, how do you know that she has reached her full adult height already?
I have a teen-aged kid of my own, and I simply make sure he doesn't eat highly processed junk, wheat in excess and nasty oils. I don't make him restrict macronutrients.

Uh, at 14 she's hardly done growing. I didn't stop growing a lot until around ~18, and even after that I added an additional inch or so before I was 21.
VLC is ridiculous at any age, specifically that young. Expect her to struggle in all aspects of life on that diet at that age.
When I was a teenager I ate even more carbs than I do now probably, and I couldn't imagine how bad I'd feel restricting my diet at that age. If my mom tried to control what I ate, I'd rebel and just eat at a friends house and sneak junk food all over the place. Have her eat her fill of fruit, and other starches, it really doesn't matter at that age. No one should be dieting, your metabolism is at its peak anyway.
Girls reach their full height around two years after menarche. It's usually about two inches.
Give her some carbs. It won't hurt her. Carbs are great after sprinting!
I think mark's water info is nonsense. Much like his carb curve. But I digress...my water intake never changed from pre-paleo to now at least a gallon daily. Probably closer to a gallon and a half when it's hot out or on workout days.

It is why you often see at late elementary and early middle school levels, most guys are actually shorter than their female classmates on average. Then this reverses in high school because the guys continue to grow while a lot of the girls have already (mostly) stopped.

It depends, and I was using growing as a blanket statement really. I only included my height for an example.
