No idea, but the thing is that Saitama has limitless stamina. Our body requires oxygen to work and move. The more we move, the more lactic acid is produced, and the more oxygen we need, which results in more oxidizing, which leads to aging, corrosion and erosion of body parts and ultimately, death.

Saitama, however, has a body that can no longer produce harmful toxins at all due to the fact that he is limitless. So yeah, Saitama might be immortal.

Saitama fasted as a program for the training regimen. It might be possible that Saitama just pretends to be hungry and that's why he buys food, drinks and eats out of habit.
