I was a latchkey kid for the most part, so there were many days I skipped breakfast entirely. Not much soda while I was growing up, although by the time I got to college, I started drinking soda by the gallon, but was able to burn it off pretty quickly until I reached a certain age. Then I started gaining weight, although for a time I was bicycling to work and lost more than 50 pounds in one summer. I also gave up soda and drank only water, which was also helpful for losing weight. Nowadays, I only have an occasional soda, nowhere near the level I consumed in the past.
