What is 5DPT?

What is the 5 day pouch test and how do I do it?  I have rapidly gained 20 pounds without any change in my eating habits.  I need to nip this in the bud.  Please help me.

Its a way of "resetting" the pouch, decarbing, getting back to basics, etc. Here's the link with all the details~
