I really don't think Biko's game plan was to "out starve" the others???
He was REALLY trying to find food, just bad luck finding it...
He was in a real windy spot, making casting difficult to catch fish, though he did catch a few!
His gill net while well made, was largely unsuccessful..... The dude tried to boil and eat PINE BARK!!
He did pack on pounds before, going in at 300+# but that was because it's common knowledge that EVERYONE in past season looses an enormous amount of weight. He had the mental strength to convince himself, that everything he was doing, and going through, was for his family.
