Nutrition is the foundation for Performance…. not to mention health and wellbeing.
“Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat.” (CrossFit Journal, September 2002, “The Garage Gym”)
The food we eat has a direct and immediate effect on how we perform, whether it be our workout or any other task we face on a daily basis. Eat foods that “support exercise not body fat”. The idea is to eat foods that were intended for our bodies and avoid as much as possible foods that weren’t. Foods that are high-glycymic (a food’s propensity to elevate or spike insulin levels) should be generally avoided.
In CrossFit we teach 2 different nutritional approaches. The first is the Zone Diet, and the second is the Paleo or Caveman Diet.
Here is a simplified version of the Zone Diet that was published in the CrossFit Journal that you can download as a PDF article. The Zone Diet is a diet that focuses on balancing hormones in our bodies that are released by the food we eat. It uses a 40% Carbs, 30% Protein, 30% Fat model and helps to balance the macro-nutrients that we consume.
The Paleo Diet, or Caveman Diet, requires that we eat lean meats, nuts and seeds, vegetables and some fruit, little starch, and NO sugar. While the Zone Diet requires accurate weighing and measuring of food, the Paleo Diet does not require WAM(weighing and measuring). The idea is to eat plenty of the above mentioned food throughout the day. We have seen similar results from people who have used both diets. They lose body fat, get stronger and faster, and feel better throughout the day.
For most people, the battle to eat healthy foods and avoid harmful ones is on-going and never-ending. The need to educate yourself and those around you about how to eat healthy is vital. I personally think that these are great principles to base your nutrition on, especially having tried and tested them both. It did increase my performance, I did lose body fat and I felt much better in general. I do however, understand that personal lifestyles/environments can restrict flexibility in Nutrition which can make it hard to follow these principles 100% – but I do believe that people can make the best out of a bad situation and help themselves as much as possible.
