Weight loss: Too much of a good thing?

A few months ago, I lamented my weight, which was a shade over 170 and figured I was drinking too much wine during the week, which was causing my weight to stay the same even though I was running pretty much four to five times a week, averaging close to 30 miles a week.
Then, I figured out that I could keep drinking wine and still lose weight reasonably as long as I picked up my pace during my morning runs. Say, from 9:30 minute miles to under 9.

Of my last 15 runs, 14 have averaged under 9 minute miles, including five under 8 minute miles.
I got on the scale today after a 6-miler and it read: 1 6 2

Whoa. Now some of that is lost water weight from the run. I was 166 when I went to bed Monday night, with a nice wine buzz courtesy of a 2004 Marietta Cellars Zinfandel. (Thanks for the recommendation, Run Dangerously. It was a yummy wine, very fruit forward.)

I don't wanna be confused for a the kind of person who frets about every pound lost or gained. In fact, I worry that maybe I'm losing weight toooo fast. We're talking about 8 pounds in two months. At this rate, I'll look like the black, male version of Karen Carpenter by October.

So what do I do now? Keep running fast. Keep drinking wine. Eat more donuts.
