I'm a vegetarian so the "paleo" diet wouldn't work for me, but you don't need to follow a strict diet such as the paleo in order to get healthy, fit, and lose weight in the mean time.

If you want to do it and it works for you, great! I just think people are getting too caught up in these new, strict diets, and they won't be able to sustain them. Don't get caught in the "all-or-nothing" mentality. Do a lot of research, and start slow in order to increase your chances of sustaining a diet such as this!
