Could 100% Energy Efficiency Create Super Humans?

[Peaceful]

My science teacher told me the human body is only 38% efficient at converting energy, if we were able to to convert energy at 100% efficency we would be "Super Humans"?
As in heightened senses, amazing endurance, incredible speed or we would just die or something?

No, it simply means you would not excrete, sweat or otherwise dispose of incompletely combusted fuel. You'd simply defecate carbon ash.
