Pouch reset
I did a version of a pouch reset back in May. I drank protein shakes for breakfast and lunch and ate a small dinner of protein and veggies. I did it for a solid week. The first day was easy, days 2-4 were miserable, but after that it was manageable. In general a pouch reset works if you need to jump start your weight loss, however some people have thought a pouch reset will clear out all the bad habits they've developed. Unless you address those issues then all you'll do is be hungry and miserable for a week. So if you have the determination to stick with proper eating and daily exercising then the pouch reset can help.
