Good way to lose fat: walk on an empty stomach

Anywhere from forty five minutes to an hour should be enough walking. The best times to walk are right after you work out when you're body is in fat burning mode and in the morning after eight hours of sleep.

Why the walking? Sprinting is too hard on the joints especially after you've been taxing your body with heavy squats and deadlifts.  Also jogging and long durations of torturous cardiovascular activity induce cortisol production in the body.  Cortisol is basically a catabolic hormone that breaks down muscle tissue from what little I've read about it.

This guy recommends burst training as a way to lose fat.
