I've been primal for 6 months now. Went from 240 to 196 and am feeling great. I've been having a very odd problem the last few weeks while intermittent fasting (which I do 2-3x a week due to scheduling and convenience).
My fasts typically are 18 hour fasts, broken at 6pm at which point I normally have a Big Ass Salad, some sort of fatty meat with copious amounts of butter, cocunut milk, olive oil, etc. Around 8:30 or so I typically also have 3 eggs or some nitrate-free meat and a piece of cheese or olives. I fall asleep around 9:30 (I get up at 5am). Around 10:30, I awake, ravenously hungry for carbs. I've tried the drink-a-glass-of-water trick, 5-HTP, eat more protein/fat, but I literally cannot fall back asleep unless I have carbs, which, unfortunately, usually consists of peanut butter or something else non-primal. Before I went primal, I used to engage in similar 10:30 pm behavior. I fear that my body craves this insulin release as a precursor to sleep. (Also, I've tried sleeping aids, and all they did was make me eat sometimes unconsciously at 10:30pm!)
I see three potential problems:
1. psychological "dependence" on this insulin rush.
2. intermittent fasting is not for me, and my body needs to eat throughout the day
3. did I use up my body's "willpower" by 10:30pm and I just simply give in? (Mark had a great post on this concept a while back, which blew my mind and made a lot of sense: http://www.marksdailyapple.com/increase-willpower/)
Any insights/tips/strategies, etc. would be most appreciated...
