When I did leptin reset (partial success), I discovered that I craved sweets after the meal too. The "full" and satisfied feeling that you're supposed to get didn't truly kick in until 1-2 hours after the meal. If you can stave off the craving for an hour, you can usually get past it. My solution was to go to the mall or go for a drive to get away from the house.
My downfall is not quite the sugar, it's that sugar foods like chocolate pieces and twizzlers are so easily packaged to eat out of hand. Sorry primals, but you can't just dip into a box of steak like you do for Junior Mints. I suppose I could dip into a container of berries, but they cost 5x as much as Raisinettes.
5'0" female, 43 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained to 110 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.
