My 7 year old brother went to the doctor on friday and they told him he was 1lb overweight and should be put on a diet. My mother said look at him, hes skinny as a rail, all his bones stick out and people sometimes wonder if he eats enough.
They looked at him and admitted that he was on the thin side and still they insisted the cutoff is 55lbs and he is 56 lbs and needs to eat less.

BMI charts are worthless.
