The explanation, like all these things, is that he is a fraud. Nobody generally watches him at night, when he is free to move / eat as much as he likes. The longest time he's been monitored on camera is 96 hours, and people can survive longer without food and water. Note that he sits perfectly still for this entire time; his body isn't exactly requiring a lot of energy. My theory is that he has knowledge of when he'll be filmed, and prepares for them in advance.
Oh, and during previous filming, infrared cameras at night failed to pick up any evidence of a body (the film crew were required to be behind a fence). All evidence we have suggests he moves around at night and that is when he eats, etc.
