So, PB can mean shooting for 80 out of 20, and that seems to be what a load of us shoot for. You hear "... well, just chalk that up to your 20% and don't worry about it..." on the forum from time to time. To that end, have any of you ever logged, you 20% indulgences?
I first got Mark's book and had already gone a long way down the Paleo Nutrition road. I read his 20% allowance, and thought he should really have stated 10%!! But that may turn too many folks away from all the good even 80% will do.
Some reflection on stacking up all those 20% shrugs just might surprise a PB follower. If anything is not coming around, over the long haul, consider logging that 20% for a week, a month, see what it REALLY adds up to! 20% can slide into 30% pretty easily.
