As the name suggests, high intensity interval exercises are great to lose weight in no time. But remember, you shouldn't do it for more than 20-30 minutes, because it is hard for your body to take the load. The good part is you continue burning calories even after you are done, thanks to EPOC or excess post-exercise oxygen consumption. In general, I don't believe more than a 1% drop in body weight per weeks is a good idea. Rapid weight loss isn't necessarily a problem in itself, but the issues that you may develop along the way are. There's a good chance you'll develop an eating disorder, which is super counterproductive long term. .
