I Put A Spell On You

Simple and succinct, here is an article on ideal macronutrient ratios for CrossFit exercise written by Lon Kilgore.

I think the key points to pull from this piece are:

1.) changing body composition is not voodoo. its science, and basic science at that.
2.) energy in, energy out. there's no way around the 2nd law of thermodynamics.
3.) diet without exercise works, if you have 20 years to lose a few pounds.
4.) 40 carb/30 prot/30 fat is close to an ideal macronutrient ratio for CrossFitters
5.) high-quality, non-processed food is ideal and always has been.
