My son is very sporty, likes to be fit and healthy but has just told me that he thinks he is fat. From what I can gather he thinks this because he has age 15-16 trousers to get the length as he's 5 foot 9ish. Waist wise he still fits into age 13-14 trousers but they are too short.
He's now told me that he sometimes goes to bed hungry because he doesn't want to eat dinner, I put it down to have a cooked meal at lunch time which is late at his school - 1.45pm - and so not being hungry at 6pm when we usually have dinner.
His BMI is 22. He's on the 92nd percentile for height and the 82nd for weight.
