A combination of both cardio and bodywork will do wonders. Try to balance the two according to your time and preferences but so not neglect one of them. I run/jog almost daily and do strength workout twice a week.

Cardio. A simple raw run also helps. Although if you want to build muscles in place of your fat than do so, but if it is just for being fit than cardio is sufficient in my opinion.
