A timely article today in the New York Times - "How Exercise Changes Fat and Muscle Cells."

The more I run - longer/shorter, differing intensities - and with more frequency through the week, the less my apetite is suppressed. If I'm really into it - working up for a marathon or something - I'll completely forget to eat a lunch or a supper sometimes.
Swimming used to be the opposite for me - intense, frequent exercise but an appetite that would never end. Not sure what was up with that.
Good luck with your efforts. The follow-thru, when the cameras are gone, will be the most important I think. Easy to slip then. Its about making lifestyle choices and employing discipline. And enjoying the new lifestyle.
Best wishes.
