I have always been thin. But since I had gb and hundreds of stones removed, tears and leaks repaired and some bile ducts partially removed I have put on 55 pounds over 2.5 years. Totally unlike me. I am over fifty. Not a typical problem for me. I have a slim body type and a fast metabolism. It changed my system. I see everyone’s posts and I think some of those who don’t have this problem don’t understand that it really does change your system for those who do understand and are offering suggestions, I am thankful. It is baffling. I have totally changed my diet. Not that I needed to that much. I’ve always eaten pretty well. Also, being over 50 or my age slows the metabolism as well. I guess I’m just sharing a little empathy.
