I follow Weight Watchers and ride for part of my activities. I also spin once a week and am now incorporating weights. I started WW this time in July/August 2010 and have lost 67lbs. decided that I wasn't going to give up any one food group but restrict portion sizes. I knew that this time it was going to be a lifestyle change and not a "diet". I will keep up the lifestyle after I reach goal in approximately 30lbs. Just get out there moving and control your portions. Good luck and enjoy your riding.
