Can human survive without food?

I recall the show on Discovery Channel, it shows that this guy in India had not touch food or water for the last few decades. Well at a very least in a controlled environment, he had done that for 10 days under surveillance.

Can it be done? I am no biologist to say so. But probably at an atomic level, it can be done. Atoms gain energy by absorbing electrons. Molecule are form by the combination of atoms. We are in constant contact with atoms and molecule. Perhaps he has a way of absorbing them through the skin? So he does not need food or water, where the molecule of foreign body are ingested and assimilated as our own.
