I'm subscribing to this thread, so if any questions for me arise, I'll be happy to discuss aspect of diet, bariatric surgery and how said surgery requires modification of diet for endurance cycling or you can PM me, either one. I do need to state in advance that I will be relating from personal experience and experimentation. There isn't a lot of data about post bariatric endurance athletes, and in effect, I'm on the 'bleeding edge" here, with my surgeon and dietician tracking my data as well as myself. It won't ever be medical advice, but my best considered suggestion to use at your own risk. That said for the lawyers, let the games begin!
