Do you want to supercharge your weight loss? There’s just about nothing more effective than this. We’ve reached the very end of our series on fasting for powerful weight loss, diabetes reversal and for simply feeling better.

In an earlier video Dr. Jason Fung described how to get started with fasting on a 24-hour fast. In this video he details how to do something you may consider impossible: to fast for a week, seven full days.

It’s not necessarily easy, but it is quite possible to do if you have excess weight to lose. It’s also very effective. In this video Dr. Fung tells you just how to do it, and what you need to succeed.
