01WhiteCobra can definitely handle this topic a little better than I, but I have always read that 20 minutes is the minimum amount of time required to effectively get into the fat-burning zone. Obviously, doing more would prolong your fat-burning effects, so I would recommend atleast 30 minutes of moderate intensity cardio and preferably an hour if fat-loss is your primary fitness goal (meaning lean-mass isn't of importance dring the current phase).
