At this point, I'm going to have to structure my 20%. If I don't cheat in a controlled manner, I'll cheat in an uncontrolled manner, like raiding my emergency storage at night for packets of Swiss Miss. Bad girl! So here's my 20% plan:
Breakfast non-primal: 1 scoop whey powder in the smoothie.
Lunch non-primal: 1-2 ounces 85% fair-trade chocolate
Dinner non-primal: 3 Jones pork sausages <-- might be mostly primal since the ingrediants are "pork, water, salt, spices, sugar." no gluten, nitrates, or MSG.
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained to 109 on sugar cheat. Reset with 85P / 90C / 90F. Currently weaning off fat to 85P / 90C / 60F.
MY PRIMAL: I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and other need to tweak Primal to their own needs.
