The world's biggest boy.

This documentary follows obesity specialist Ian Campbell as he travels to the Far South of Russia to meet Jambik who, at seven-years-old and 16 stone, is the heaviest child in the world. In order to work out the reason for his extreme obesity, Campbell observes Jambik at home and school before flying him to Moscow to run some hospital tests on him. It becomes clear that Jambik's mother is feeding him anabolic steroids to make him grow big because his celebrity is bringing them a much better lifestyle than they could have imagined otherwise - but how can Campbell persuade his mother that the way she is raising Jambik is killing him?
