Firstly let me say, you look great.
I didn't read the entire thread, so forgive me if this has already been suggested, but, are you eating enough?
If you are still you are still trying to lose weight by restricting caloric intake & exercise, then you are going to call me crazy.
At this point in the game , your body has adapted to surviving on low calories. You need to calculate your base metabolic rate & add your caloric burn to it. Then bring your caloric intake up to at least that number for about a month. This will convince your body that it is being well nourished & it will quit holding tightly to fat stores. Then you can go back yo the pouch test or any other calorie restrictive diet you choose. You'll notice that then & only then will your body release the fat stores. If you don't reach your goal in 2-3 weeks bring your calories back up and repeat the cycle.
