See what Chadley wrote above.
Cardio will help you to lose weight of course (provided you don't "eat back" the calories you expend); however you'd be better served by a clean, protein-rich diet and building some muscle (not really possible in a caloric deficit past a certain point, but at least muscle maintenance) imo. If you do tons of cardio and eat significantly less you'll lose muscle mass. Also, don't think cutting fat out of your diet is the be all and end all. Fat is good, you need some, just not too much.
Ultimately if your only goal is to lose weight, consume less calories than you expend, it's literally that simple. As an addendum "belly-fat burning" or any other form of spot reduction is largely a myth. Lose fat and eventually it'll shift from the region bothering you. It should be a long term plan, not a quick fix.
