Too often people want to make things too complicated. What we teach people is in this order 1. Quality (eat mostly whole foods) 2. Quantity (eat enough to support your athletic activity) 3. Variety (mix it up so you get varying degrees of micronutrients/vitamins) 4. Timing. Our book Met Flex for Fat Loss focuses on eating moderate amounts of carbs around your workouts. It was written in conjunction with me and for this site, a site where the majority of people do Crossfit.
