How effective is mountain biking when it comes to weight loss?

I'm a little heavy last two years and I am looking for work it off. I am only a small pieces, not fat or anything, but I want the body you once had. I go to the gym 3-4 times a week, his hard work come to school and beyond that, but have a Nice mountain bike, and live next to a mountain preserve, there are MANY bike trails. It would be easier to take my bike out of the drive to the gym. But my question is, how effective is mountain biking? Is it a good form of cardio? I do weight training in the gym, usually a setting more times. Doing this will help with fat loss / / weight?

when is the weight loss is not helpful.
