I didn't read the whole thread but I'll tell you about my personal experience. A while back I read an article about how there's a collection of urbanites who go jogging daily, not because they're health freaks, but because they want to drink a few pints of beer at the pub every night, but wanted to remain thin.
When I started home brewing, I decided to try jogging in the morning for 15 minutes to counteract the effect of the beer I was drinking each night. I have one 500Ml beer (1 pint) each evening. Anyways, I'm lazy, could never get more that 3 minutes of running, and walked the last 3-4 minutes home. So, all in all, 7 minutes of arguable effort. Started with not being able to run more than 150 feet, and got it up to half a kilometer over time, which isn't much. And then walked another half kilo home.
It worked. If you start each day but running or riding a bike for 5 minutes, you're metabolize will reve up early and you'll burn more calories all day. Plus if feels absolutely great. Not the running part, that feels like death. I hate running. But once you have a shower and your first coffee, you have loads of energy. Lasts until about 5PM. And you sleep solid.
So you want to lose weight and drink lots of beer? Run for 3 minutes every morning. I lost about 20 Lbs while drinking beer, and not changing my diet, though my diet is pretty healthy.
