It looks as though you're healthy, Dave. I'd flirt with white rice, and sweet potato (skin peeled), if wanting to reintroduce typical carb sources into your diet. I'd say, get a good pull up bar, and do some of the workout programs listed, by Mark. Also, stress/lifestyle plays a big role. Since you said you were up for nap time, I don't see how it'd be a hard transition for you to take things a little slower. Welcome aboard!
