I've been meticulously watching calorie intake, staying below my BMR and riding my bicycle 5-6 days a week, as weather permits. I feel physically and mentally fantastic, a far cry from the funk I've been in the last year or so.
Mouser, buy some dark chocolate--there are a ton of studies that indicate eaten in moderation it's not just ok, it's good for you. Antioxidants, lower blood pressure, happiness (because dark chocolate is better than no chocolate!)...
On my side it is difficult to exercise (interesting times ahead), so not using the lift, parking further from the office, and giving a walk is all I can do...
There's nothing wrong with walking, soulwanderer! It's exercise, and infinitely better for you than a bag of potato chips on the couch.
Edit: And I picked up one of these: Fitbit One
-- so awesome.
