People also grow more since then and diets change. I'd love for the industry to remove sugar and therefore unnecessary cravings for a lot of people. In theory: smaller humans would be the ultimate solution. But that's not going to happen anytime soon. Perhaps a way more efficient digestion system? The fallacy of the op is to exercise more ( = use human energy for transportation) and eat/drink less. That's not how the human body works...
