From what i understand, it is best to eat every 2-3 hours. The reasoning behind this is so as not to overload your body and waste resources but also because this will make you bloated and lethargic and obviously effect training. however, knowing this and sticking to this is easier said than done unless you are very disciplined.
I sometimes miss eating to this plan and the first reaction is mental distress and stress can have a physical impact upon the body, so not only am i missing out on steady flow of resources but also possible physical damage at a cellular level.

therefore, my question is what difference if any will long periods between meals have upon a bodybuilder?

The traditional nutritionist opinion is still supporting the eat 3 times a day option which obviously deviates from eating every 2-3 hours, and also the meal regimes in the military are based along these lines. Therefore, i do not suppose it is harmful but maybe not optimal for mass bulking.

i dont have the time at present but will check later whether the delay between meals has any effect upon fat loss or whether the opposite and fat gain is apparent. if anyone can link in the meantime it will be appreciated.
