I am many years post-op and, unfortunately, have gained a lot of weight back. I initially lost most of my weight by drinking protein shakes and fruit and vegetable smoothies. However, my metabolism seems to have changed since menopause and I suffer extreme bloating now whenever I drink protein shakes or fruit and vegetable smoothies. I have tried most kinds of over the counter gas medication, as well as, pre and probiotics, peppermint and fiber. Nothing seems to work. Has anyone else experienced a change in metabolism with menopause? If so, I would certainly appreciate knowing what if any supplements you may have found that help you digest protein and sugars.
