I've completed ONE 30 day Paleo challenge several months ago; now I'm trying a second one, with a twist. After watching the video on netflix, "Fat, Sick and Nearly Dead," I bought a juicer. Here's my personal challenge: a 10 day juice fast (maybe longer) and Paleo or Juice modified Paleo for the remaining 20 days. Why not juice for 30 days, you ask --> As a conivor, I think (believe) I need meat or fish on a regular basis. BTW: Juicing a bunch of veggies together tastes better than eating them individually.
