Did the OP ever post again? Wondering if he found any of the advice to be worthwhile.
Well, FWIW, I got motivated to get back in something resembling peak condition for me again. So... no booze (heavy sigh), more running, and some further care in sticking to my already mostly spartan diet (not counting the beer, wine, and vodka that is), and four weeks later I've cut my bodyfat down to around 8-9% again (?!). Overall weight loss is minimal -- just a few lbs, so for once I've managed to keep the muscle and just drop the flab (not so easy for me based on past experience).
To everybody else who posted who is working hard to get in shape -- good job so far, and keep at it -- it will pay off if you are determined and disciplined!
If you slip -- tomorrow's a new day. Resume and keep going! Good luck!
