As your workouts increase in intensity, so will your appetite. In order to receive the benefits of your physical activity, eating right is essential. Just as diet alone will not produce noticeable results in health and fitness, daily WODs alone will be diminished by poor nutrition. If you eat right, supplements are only “icing on the cake” rather than being needed to fill a void in your diet.

Diet Programs

There are three common diet programs that many CrossFit’ers recognize as providing the necessary ingredients to keep them going strong: the Zone Diet, Primal Diet, and the Paleo Diet.

The Zone Diet

This program was developed by Dr. Barry Sears in response to his research on how the body responds to (or doesn’t respond to) grains. Ultimately we want our sore and inflamed muscles to recover from high intensity workouts, and he believes this diet to be best from that. The best place to look for an overview of the Zone Diet is on their own website: This diet is recommended by CrossFit HQ as well. See their suggested meal plans based primarily on the Zone Diet. Perhaps the best place to look for a thorough explanation for anyone seriously interested is at the website for CrossFit Impulse.

Primal Diet

This diet is best explained by the guy over at Mark’s Daily Apple. He says this:  “The Primal Blueprint is a set of simple instructions (the blueprint) that allows you to control how your genes express themselves in order to build the strongest, leanest, healthiest body possible, taking clues from evolutionary biology (that’s the primal part).”

The Paleo Diet

The previous two diet plans require a pretty significant amount of weighing and measuring in order to ensure correct nutrition. The Paleo Diet is much less “scientific”. I learned all I need to know about this diet from Steve Kamb, creator of Nerd Fitness. He says: “The Paleo Diet is an effort to eat like we used to back in the day…WAY back in the day. If a caveman couldn’t eat it, neither can you. This means anything we could hunt or find – meats, fish, nuts, leafy greens, regional veggies, and seeds.” If this makes sense to you, check out his complete “Beginner’s Guide To The Paleo Diet” where he offers more resources to dial in anything you need to know.
