I'm 6.5 month po and have been in a stall for almost 2 months. The scale finally moved this morning! HalleluYah!
Stalls are a normal part of the process. You just have to trust that if you're doing what you're supposed to do, your weight will eventually get to where it's supposed to be.
After surgery, our stomachs are traumatized. They are firm and tight, due to the trauma of surgery. Because of this, we have a lot of restriction. It takes about a year for them to fully settle down and relax. As your tummy relaxes, you will be able to eat larger amounts of food. We have to be mindful not to overeat, as this happens. Just because we can, doesn't mean we should.
