We had a thread awhile back (not sure how long) that talked about how Moose and Guyon were having a weight loss competition for Blade Show. That got several of us interested in getting a little more healthy, and there were several of us that participated. I think that because of that thread I lost somewhere around 15-20 lbs. I gained some back due to laziness, but not too long ago I tried to get back on track, and have since lost some more weight. I ain't skinny, and I know for a fact I could stand to lose some more weight, but I am doing better than I was, and I am in the process of losing more.
What did it for me was just watching how much I eat. Cutting down on portion size alone was hugely responsible for most of the weight loss I have managed to achieve.
