I know a guy who was promoting frutarian lifestyle. He was a previous world champion kayaker and works in the outdoor industry. I saw him recently and he was still in the top 15-20 in the world in his even. I need to check with him if he's still doing it. He looks like a model, superfit and full of energy. He had an interesting blog on the amount of fruit he was having to eat, most of which he picked up for free or cheap at markets as it was approaching use by date.
