Paleo Diet- Who's a fan?

For some reason I have been coming into contact in conversation with the Paleo diet everywhere I turn. I heard about a friend who was trying it, a doctor who told me about it and even the event DC Heathy Bites I'm attending is having a guest speaker who will be discussing it. Do any of the you out there have thoughts about this diet or have any of you considered trying it? I have to say I'm kind of intrigued. For starters, it's really supposed to help people with hypothyroid and autoimmune diseases (which I have both of). It's also supposed to help people with diabetes and other diseases. It does follow our gluten free lifestyle. It just however takes it to such extreme measures. I'm totally on board with following a no processed food, completely healthy lifestyle, but it does appear to be very limiting and tough to sustain.

For those of you who are not familiar with the Paleo diet the premise basically is to return to our healthy roots and eat like our ancestors, the cavemen. So basically, we only eat what comes from nature. The diet consists of meat, veggies, and fruits and nuts. Everything else is restricted. So no grains (even restricting rice and potatoes. Sweet potatoes are for some reason ok though) no beans, no caffeine, no alcohol etc. The one redeeming fact of this though is that it is stated that as long as you follow this diet 80% of the time you will see the benefits. So you are allowed to cheat :)

The plan does list many benefits including better health, better skin, weight loss :), more energy and just an overall better feeling. And you are supposed to feel the effects within two weeks of trying it. There are a lot of good recipes out there as well, it just looks like you definitely will be required to spend a lot of time in the kitchen and planning ahead to sustain this lifestyle. So what are your thoughts on this? Could the possible benefits outweigh the inconvenience? Would any of you be willing to try this diet? Please weight in, I'm curious to hear your thoughts.
