CrossFit nutrition - zone diet, macros, or just eat?
Started CrossFit 4 months ago and I love it. But the gym pushes the Zone Diet and it seems really complicated with all the "blocks." Is there a simpler approach to eating for CrossFit?
Zone Diet was popular in early CrossFit but most serious CrossFit athletes have moved on to standard macro tracking. The principles are sound (balanced macros, quality food) but the block system is unnecessarily complicated.
Simple approach: eat enough calories to support your training, get 0.8-1g protein/lb, fill the rest with carbs and fat. Done.
CrossFit is glycolytic (uses a lot of carbs). You need MORE carbs than most diet advice suggests. Low carb + CrossFit = feeling terrible. I learned this the hard way.
I do CrossFit 5x/week and eat around 300g carbs on training days, 200g on rest days. Performance is directly tied to carb intake for this kind of training.
CrossFit is basically a mix of weightlifting, gymnastics, and cardio. You need to eat like an athlete, not a dieter. Don't underfuel or your recovery will suffer and injury risk goes up.
Most of my CrossFit clients eat 2200-3000+ cals depending on body size. The volume is too high for aggressive dieting. Focus on performance and body composition will follow.
This is great. I was trying to do CrossFit AND eat 1800 cals and I was dying. Gonna bump up calories and carbs and see how I feel. The Zone Diet blocks were just stressing me out.
Meal prep is essential for CrossFit. You need to eat a LOT and having food ready prevents reaching for junk when you're starving post-WOD.
Add electrolytes to your water, especially after sweaty WODs. Sodium + potassium + magnesium. Cramps during wall balls are no joke.
