I'm new to paleo and incorporating at least some paleo elements into my diet (increasing fat and meat intake, eliminating grains and sugar, decreasing industrial oil intake), shooting for fat loss and, more importantly, improved well-being (including reducing my tendencies toward food obsession). I may not ever be "all the way" paleo (loath to give up dairy and legumes—except peanuts and soy—entirely, loath to vow that I will never, ever eat wheat or sugar again even when I'm drunk and it's 4:30a.m. and everyone's going for pizza), but I'm definitely interested in what paleo has to teach me, and even just in the couple of weeks I've been tinkering with paleo principles in my diet, I've felt an improvement in satiety and a reduction in food anxiety.
In my recent reading about paleo eating, I've heard a fair amount about the 80/20 rule—do you think this applies to eating paleo? What do you think are the 20% of behaviors that have 80% of payoff in paleo eating?
