I have a question for those of you who work out. They say the most effective way to burn fat is to do interval training. What exactly is that?

I've heard you can run 5 minutes, walk 5 minutes for 30 minutes multiple times a week.

or

you run for 15-20 minutes two days a week and then do a long walk, like 40 minutes, for 2 days.

I've read that you should keep your workouts short 15-20 minutes of cardio, to burn fat, but if you go longer than that, your body will actually hold onto the fat, thinking it's being overworked and it needs to hoard calories. Yet for good cardo health you should do longer workouts every now and then, just not all the time.

What's the best way?
