I equate it to lactose intolerance. Some lactose-intolerant people can have milk but only up to a certain limit.
Similarly, I have slight reaction to gluten (acid reflux), but only if I have a lot of it. So at office parties, I can get away with a square inch of cake or one donut hole and then explain that's all I'm allowed... but oh how it tastes so good. (and actually it does kinda taste good). This tack has worked well with everybody.
solstice, why not bring your own salmon dish to Thanksgiving next year? Then you can avoid the turkey without making demands on or burdening your family... and they can have some salmon too!
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. Current weight: skinny-fat 106 lbs. Resetting with the 21-day challenge.
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 aim for 80-90 g carb/day and advocate a two-month strict adjustment for newbies. But everybody is different and other need to tweak Primal to their own needs.
