I think the paleo diet is just a “sexy” word for eating whole natural foods, rather than food-like-products that don’t naturally exist. And of course if we eat this way, we will be healthier (and lose weight)!
Also the restrictions placed on non-paleo foods is confusing. For example rice is forbidden. Yet the people that live the longest, healthiest lives – from Okinawa in Japan – have a diet that is more than 70% rice (white). Plus some vegetables and some meat once in a while. They are living the longest.
I have tried eating Paleo and lasted only 2 days. I stopped after I ate a steak as big as a plate in addition to an entire plate of vegetables (I was planning on saving leftovers for the next day’s lunch). I was still hungry for more after eating these huge portions.
I broke the diet and ate some whole grains because I figured that if I’m that hungry, I’m not getting all the nutrition I need from the food I’m eating.
That said, I think eating mostly paleo is the best way to eat (mostly vegetables, a bit of meat and fish, and also a bit of grain), as long as you listen to your body and don’t get stressed out over it.
