There are a few tricks you can use if, like me, you really detest long-duration cardio.
First off, you can inactivate your fat storage enzymes just by keeping your hips extended. Don't sit down. If you spend a large part of your day sitting down (hips bent) then your fat storage enzymes will be activated during that time... simply standing at your desk (rather than sitting) can, if practical, dent your fat storage capacity.
Secondly, you can use a thermogenic effect by slightly, very slightly, lowering your core body temperature. Just sipping on an ice-cold drink (sipping, not gulping) throughout the day (freeze a 1 litre or bigger water bottle and sip it as it melts throughout the day). By sipping continuously you don't frighten your system into a state of cold shock, which you would by cooling yourself by immersion, or cold exposure.
Those two tricks, in conjunction with the usual calorie control; insulin control (meal spacing); low carb, low-GI diet can all but make cardio redundant.
