"so many have used, and attribute their successful weight loss to cycling"
The problem with that is we don't know how many people have tried cycling to lose weight and either not lost weight or gained weight.
Certainly it's better to be have a fit cardiovascular system than not, for at least a few good reasons. Exercise, though, for most of us, means we want to replace lost energy, i.e. it makes us hungry. Hence the phrase, "working up an appetite."
Personally, I'm not hungry at all after a good bike ride. That only lasts for a little while, though. The harder I've turned the pedals, the less I've eaten during a ride, the hungrier I become as the minutes after a ride tick by.
So I'm pretty sure that for most of us, it's not exercise that makes us lose weight. It's taking in less energy. And for most of us that means, short of a forced hospital stay, exercising our will over how much energy we put into our bodies.
