I've been playing around with intermittent fasting. I found this article which I really liked - especially the bottom part about fat loss.
"I have never seen fat disappear as quickly as I did with the following protocol:
While still in a fasted state, do a brief HIIT (High-intensity Interval Training) workout. This can be Sprint-8 (running or rowing), or just 50 burpees in hard sets of 10. Something to spike your heart rate a few times. This will burn through any glycogen you have remaining in your muscles after sleeping, and stimulate your body to release some fat into the bloodstream for energy.
Follow this up with about thirty minutes of easy cardio - something about 60% your max heart rate, so just light jogging or some biking. Nothing too rough - all you're doing now is burning up the fat your body released.
By now your body will be struggling to keep up with your energy demands. The longer you can wait until you eat, the more you'll burn, but be careful - you can bonk pretty hard.
Do this 2-3 times a week."
