Freak seeing as though your a fatty and you're trying to burn fat ya cant go wrong with a bit of everything. Some low intensity steady state stuff maybe before breakfast ( the thai runs are perfect ) but 1-2 a week max, maybe an interval/fartlek type run and some anaerobic stuff once or twice like stair / hill sprints. That way your getting fit and losing fat. Just my opinion. I can't stand steady state cardio it bores me to near suicide but I love hiit style stuff, its hard work mind.
