DIET: NUTRITION IS IMPORTANT
Diet can be complicated, so always consult an expert and/or physician before beginning any diet.
As a starter, there is a ton of information on the web as well as a couple of books Zac recommends to educate you:
Nutrition is really simple. You just need to know your diet and execute it. It takes discipline, planning, preparation, practice… sound a little like hunting? Just focus on one major change at a time. For example, the first week cut sugar-packed drinks and sodas from your diet. The week after swap a bag of chips for a piece of fruit. As you progress and trim away the bad habits the good ones will become second-nature. You’ll love the way you’ll feel and that will drive you to continue improving.
Zac Griffith’s diet is high in lean protein such as wild game, chicken breast, fish, egg white and protein powders/bars sparingly. Zac recommends eating as much green vegetables as possible along with 1-2 gallons of water daily. Carbohydrates are an energy source and should be consumed early in the day and sparingly.
