I thought that too, that the extra food (calories) I eat disappear as I ride. But after around 500 miles in 2 `1/2 months my weight is the same. I took to much stock in mapMyRide app telling me how many calories I have lost. There was an over whelming agreement that it was way over blown. I calculated it and mapMyRide was saying I was burring about 80 calories an hour. For the most part I just cut that number in half and also started to curb my diet. I thought I would go down in weight eating the same food but just adding riding to my list. I am glad I asked and now have an idea of what I really burn.
