How strict should my diet be?

[leggy]

do you think a 15 year old who has just been carded should monitor his diet ? im in perfect shape, but i eat loads and sometimes a bit of crap

Yes,the eating habits you form now will stick with you later,your metabolism finally slows down,that Big Mac isnt going to come off as easy in a few years

cheers mate i will sort it out then as hard as it will be the sacrifice will be worth it
