Funny how I've changed in a relatively short period of time. When Mark asked this question as part of the challenge, my 20% was mostly taken up with a daily oatmeal, albeit made with ever decreasing ratio of grains to eggs. Right after sending in that response, I figured...why am I spending my 20% on ONE thing? So I quit it and haven't eaten oatmeal since.
For me, the 20% is very much dairy. I probably eat more than is ideal, though I've switched to grassfed, or raw when I can get it. The only issue I'm curious one day to experiment with is whether I'd improve my skin by quitting it entirely. An experiment for the future!
I count 85% or less chocolate as part of 20. 99% is part of the 80 to me.
I eat some almonds.
Occasional glass of wine.
I don't count coffee or tea in the 20.
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
