My 2 cents: you won't be able to lose weight cycling. I know lots of people on BF have done just that. However, read through old posts and note that many of these people admit to totally changing their diet. In fact, they could have lost the weight with the diet change.
Getting in shape has many benefits and you should certainly keep riding, OP. however, exercise will make you hungry. How hungry? Enough to put back the amount of energy you've expended on your last ride.
