In general, more Paleo people need to acknowledge that Paleo is not a pre-requisite for fat loss, and that it doesn't necessarily work. I don't think you should necessarily expect fat loss from it - just improved health and performance. If you do it right and take care of all the other contributing factors under your control, sure, you should lose fat but it's not a given and it's not going to occur at a predictable rate for most people. That said, I think there is generally more open-mindedness, rational expectation-setting and honesty from people like Kresser and Sisson and Wolf than there is from say, Atkins or Tim Ferriss.
