I've heard that there is a new way to lose weight without dieting. What is it?

I’ve never tried it, but I’ve heard that people are losing weight by doing HIIT (High-Intensity Interval Training). It’s where you do short bursts of intense exercise followed by periods of rest. The idea is that the high intensity part of the workout will burn calories quickly and then the rest period allows your body to recover so that you can keep burning calories for longer.
