Fasted morning cardio and clean up your diet first before considering supplements. Clean will help to burn fat but your must clean up your diet first.

With fasted cardio, wouldnt that put his body in catabolic mode?

Not necessarily. You may lose some muscle doing fasted cardio, but you are bound to lose some muscle almost any time you are dropping fat. I have never noticed a size decrease on myself while doing cardio on or off season.
