Here is an excerpt from my Paleo-Food list. It's basically a discussion of
food cravings and what to do about them. Sometimes the answer is just plain
common sense......keep that pantry empty.

Another possibility -- the one that I favor -- is that a number
of lifestyle factors contributed to the leanness of paleo people.
One of them would be that "impulse eating" would have required
more work than just going to the refrigerator.  That is, I think
there would not have been much food lying around to be consumed
on a whim.  If I feel peckish I can open a bag of pork cracklings
and get 500 calories in a matter of minutes.  If I had to go
catch and kill something and skin it, well, I might just wait
until I was a bit hungrier.  I might go and find some nuts or
berries, or dig up some roots, but all of these things involve
considerably more work than opening the refrigerator, a bag, or a
jar.  In that kind of an environment, I think people would get
used to eating what they need and not much more.

In contrast, in the civilized world our food supply is radically
disconnected from our activity patterns.  One can do sedentary
work and yet have a home stocked with massive amounts of food --
even paleo food.  Every dieter knows that there is a strong
psychological component to food cravings, perhaps explicable by
our paleolithic eating patterns of long ago.  The more stuff
there is in the kitchen, the more we have the urge to eat it.
If it's not there, the craving usually passes soon enough.
