I had gastric bypass years ago and not only can I not lose anymore weight, but while biking long distances my energy level takes a dive and I can’t recover. Taking carbs and protein with me and eating every 5-7 miles, but still take a dive around mile 25. I ride the MS150 every year but since the surgery, I can not sustain my energy level to train like I need to. Very depressing!! I still want to lose 70 lbs. if anyone has gone through the same thing, I would greatly appreciate what you are doing to get through it. By the way, yes I have consulted my Dr and he said to keep the carbs coming and I do but it just is not doing the trick for the amount of energy I am using.
