Calories burned during exercise is mildly relevant, it's what you burn during the rest day that counts. Now of course having more muscle mass helps burn fat but (most) girls I know are not interested in building the sort of muscle that would have a noticeable affect on weight loss.
If we're talking about circuits, i'm referring to the kind you see rugby players doing. Bodyweight exercises, sprints, medicine ball training, ladders, box jumps etc. Try that for an hour I think you'll find you'll be sweating just a little more than doing a strength workout.
Primarily though, as already stated by a few of your posts, it boils down to diet sadly.
