As for wight gain. You are singing my song. I am a 43 year old female who had her gallbladder out 2 years ago after the birth of my 3rd baby. I’ve gained almost 20 lbs and NOTHING is different about what I eat. If anything I get more exercise having a toddler. Sorry to say I’m glad to hear other people have this problem I thought I was just deluding myself about what I ate.
