Drumroll, it looks like it's you and me against the potato hack.
From the sound of it, maybe we need to go strict primal to ramp up the fat burner hormones, and then it's okay to add in a little starch? However a whole pound is ridiculous at least for someone my size.
I'll stick with PB for the moment, thanks.
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.
