Discovered this gem in "another message forum thread on Crossfit"
With the wonderful quote:
Bunch roughly bases his intake on the Zone Diet developed by Dr. Barry Sears, which advocates a 40:30:30 ratio between carbohydrate, protein and fat. Bunch’s tweaked Zone is closer to 12:57:27.
Because Barry Sears invented the concept of macronutrient ratios. Any of them. I also like the false precision here: 57% protein. 56% is iffy, 55% is right out.
