Retired Military...Interested in forming a 20-25 lb weight loss group?

I'm a 28 year vet...always fit in the military. Retired in 2009 and have gained 20 lbs in 6 years...ouch! I still work out regularly but I know I need to curb my sweet tooth (and I'm working on it). I'm headed in the wrong direction and I want to turn around! Any retired miliitary interested in joining and supporting each other?
