I've heard of the 5day pouch test. You can google it they have a GBP website. Basically looks like starting from scratch again. Feeling that tightness of our pouches. People who do this are either gaining back the weight or feel that the intake of foods has increased. Like I said back to the basics. First couple of days is liquid only then increase the food intake each day. I don't know if it works. I should try it since I'm plateauing again.

There! Now you don't have to look it up! My doctor's team recommends it for people who did WLS some years back, fell off the wagon, and are convinced they "stretched out their pouch". Usually it's a combination of sneaky little bad habits that make you able to eat a lot more...for instnace, if you drink with your meals, especially a carbonated diet drink like Diet Pepsi that not only moves the food through the pouch faster, it helps it break down faster. "Grazing" is another issue: you don't consider it a snack since you didn't put it on a plate but you nibble little bits of non-nutritious unmeasured food all day. I could go on but you get the idea. So the pouch test is to reset your mind and your attitude as much as it is about readjusting your body. It makes a distinct break between the things you have been doing and the things you know you have to do to make this work.

All that being said...I hope I never need it!
