Here's the audio from my Nutrition 101 seminar. Food is food and what it does is what it does. There are no secrets or tricks.
You don’t need to deprive yourself, you just need to learn when certain foods help you most and do your best to eat them at that time.
The more good choices you make than bad choices, the better you will do.
No matter how hard you workout and train your body, you cannot out train a bad diet!
