Episode notes
State Of CrossFit Nutrition Research
- CrossFit-specific research is growing but still limited, covering questionnaires, diet interventions, and supplements.
- EC Synkowski finds the review useful but believes more research is needed before firm conclusions.
Surveys Likely Underestimate Intake
- Surveyed CrossFitters likely underreport calories, skewing intake estimates lower by ~20%.
- Reported protein is adequate but reported carbs (~3.6 g/kg) are lower than typical athlete recommendations.
Choose Balanced Macronutrients For Performance
- Prefer a mixed macronutrient diet with sufficient carbs for high-intensity CrossFit sessions.
- Reserve very high carbohydrate targets for multi-day high-volume events rather than casual CrossFitters.
