Years ago I was in my mid 20s and out of shape with a history of failing to lose weight, I went to a trainer who worked with bodybuilders, my logic at the time was "I should get guidance from people that dedicate their lives to controlling how they look and get so much from their diets". The no. 1 piece of advice he gave me.... "If you can't grow it or kill it, don't eat it". I've been in incredible shape for over a decade following this simple rule and its also exposed to me just how hard it is to follow this rule when traveling in the US.
