Joe makes some very good points.
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.
I actually wrote an article on eating paleo, if you’re interested check it out: http://dellaterrawellness.com/should-you-go-paleo/
