If you have time to go to the gym to do weights, throw in some cardio -- something you can handle, don't start at too high a level. Paleo is fine for some people, but it isn't really one diet -- there are many forms of the so-called Paleo diet and it isn't really Paleo -- nobody ever ate this way. Most high protein diets work for awhile, but then stop working because you hit a wall -- unless you come from a culture that has long adapted to eating a high protein diet, it's not a natural way to eat. If you find you do hit that wall, look into something more balanced and long-term that will be your diet forever, not just a "diet." Paleo probably isn't that kind of diet, but some do believe in it. I won't be on this journey with you because I don't eat that way, but just wanted you not to get discouraged if you find this doesn't work for you -- there are many ways to get to your destination. Good luck.
