I did paleo for 8 weeks and lost 14 lbs. I liked it for a jump start, but I don't buy all the science behind it. Like, I can't believe that quinoa and lentils are bad for you. But I did like it when I did it. Now I'm doing a 21 day plan from whole living magazine. Week 1 is no meat, dairy, gluten, sugar, etc. basically just veggies, fruit and lentils. It stays no dairy, gluten, sugar but adds fish week 3.
