As a follow up weight weenie story, last year during the summer I was on an eighty mile ride preparing for a century. I was riding the French bike in the previous post. With about 30 miles left I pulled into a convenience store in the middle of nowhere to use the "facilities." I bought myself a cheeseburger and quickly inhaled it. They had a 2 for 1 sale going on 64oz Gator/Powerades, so I bought 4 of them. I went out, strapped them to the rack and continued on. As I hit some hills, I noticed that I had become sluggish. I thought that the cheeseburger might have caused it. Then I realized that I had strapped 16lbs on to the back of the bike! On the hills it was very noticeable.
