Dr Michael Werner says that he has eaten nothing for four years.

The German __________________(SCIENCE) explains that he gets all his energy from sunlight. He says he drinks only water and __________________(DIFFER) fruit juices. Dr Werner has written an __________________(EXCITE) book about his experiences. In it he says that when he started the experiment he even put on weight.

He says: “I can't really give an __________________(EXPLAIN) of what’s happening to me; perhaps I just believe in my theory.” Dr Werner’s colleagues say that only plants can produce energy from the sun, and they cannot explain how he is able to stay __________________(HEALTH). “This case __________________(PROBABLE) needs a lot more research before we will be able to explain it,” they say.
