You also need to really look at what you are reading. Many articles are written about food consumption for racing which obviously can be more taxing on the energy reserves than a slower pace spin. I can maintain my weight loss cycling with good eating habits but I never lost weight cycling because I mostly ride at a leisurely pace. At least that is my thought behind it, I am losing weight right now but I cross train with running which for me was a missing part of the weight loss equation.

The latest issue of Bicycling Magazine does hav features on people who lost over 100 lbs cycling. It was an interesting read.
