I've posted this before: I think there's a physical compoent of eating bite-sized things from hand-to mouth. Before Primal it was tricuits or frosted mini-wheats. Now it's nuts or beef jerky or seasnax seaweed or -- forgive me -- M&M's. On a real binge I can pound an entire can of Pringles. It doesn't seem to matter what the food is. Hunger has little to do with it. If it's easy to eat, I eat it.
Even though they are supposedly delicious and satisfyling, real primal meals are just WORK. Expensive to buy, work to make, work to eat, work to clean up after. Bite-sized snackies are my way of postponing all that work.
However, if I'm out doing something, or walking around the mall, I totally forget about food. I can pass by the candy store no problem, or eat nothing even if everyone around me is eating.

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 should tweak Primal to their own needs.
