There's no reason to assume that they do either.

Again, it has nothing to do with the article. There were no Pringles or M&Ms back then. The article was about cooked vs. non-cooked in the paleolithic.

Which seems to supoprt Wrangham's hypothesis that Paleos could have adopted cooking in order to ingest more calories. More calories per meal = more meals available for everyone.

Maybe. I'll grant veggies because of their nature. But I find it easy to overindulge on meats - whether cooked or raw.

Play with abandon like your dog plays. That will do it :) Me, I lift weights and put

In college I knew several (American) football players who tried to get jobs at the local grocery store "throwing freight" for the same reason. Of course, I would also see them occasionally pushing cars around parking lots :)

At the same time, we used to have a subscriber named Philip Thrift (I still don't know whatever happened to him) who did pretty much the same thing on a mostly cooked paleo diet. I believe he reported losing 20 or so lbs of fat and replacing it with muscle. He cooked everything with a microwave.

Just sayin...
