overall weight will depend on his position on the field. if he has hoped to be on the o-line then he may be small. if he is a quarterback he may be perfect. overall he needs an adequate balance of protein carbs and fat in his diet. carb-loading i typically reserve more for the endurance athletes but keeping properly fueled up is very important. i think in the end good common sense is key. he is a big kid and obviously very active. he needs to eat a lot to keep up and this should be a well-balanced diet. he should also be very aware of keeping well-hydrated but not just water-loading the day of a game. i am sure there are college demographics for typical size for each position on the field but at 15 the most important factor is enough of all of the vitamins minerals and protein that his body requires to stay healthy and fit
how should my 15-year-old son (5'11" 220 lbs) be eating particularly before his football games and lacrosse games?
