I am fairly new to this site, having joined just last month. I started biking recently after a 12 year hiatus. I was in a car accident in 1998 and my right knee was damaged to the point of not being able to bend more than 60 degrees. So I did not think I could ride a bike. Last month I tried a friends mountain bike and to my pleasant surprise found out I still can. So I have been riding once or twice a week since April 4th.
When I first started, I weighed in at 281.5 lbs, and today I weighed myself and I am already down to 269.5 lbs. Eleven pounds in just under a month. I hope to keep that up and eventually get down to 200 pounds. I am 6'0" and have not weighed 200 since I was in the service.
I have changed my diet slightly, and am sure that was also a contributing factor, but the fact that I have been actually getting some exercise now instead of spending all hours in front of the computer is the main reason for the loss.
