DD is sixteen.
She is slim but not skinny and weighs 8 stone. She is 5'3.
She only eats fruit and raw veg for breakfast and lunch and has done since the middle of year 9 (she read a magazine article about it.) She eats normally at dinner time.
She swims competitively and she trains at the gym as well.
Friends think I should be worried but she's not underweight at all - would you be worried?
