I remember hearing dr. dean on the radio talk about stuff like this.
He even wondered if it would be better to eat one big meal a day vs. light meals throughout the day
I can tell from my personal experience that paleo and big meals as opposed to 6 light meals work, and are perfect when combined together.
I've been on paleo for 3 years and only eat 2-3 meals a day, in an 8 hour window, I can stuff myself till I'm full! I'm not super strict w/ paleo though, the 2 biggest things to eliminate is sugar and bread/paste/grain...
I'm in better shape and feel better now compared to when I was on lean protein, brown rice, whole grain diet, 6 light meals a day, and ran 3 times a week; I never even run anymore. Go figure :so crazy:. And best of all, I save so much time from eating many light meals a day.
