If you are worried about having gained a few pounds over Christmas, then this sobering documentary should put things into perspective.
Renee Williams, a 29-year-old mother-of-two from Texas, weighs 64 stone and is officially the heaviest woman in the world.
Having been given just a year to live, she undergoes hazardous gastric surgery that will either kill her or give her a chance at a normal life.
This could easily have been a televisual freak show, focusing salaciously on the hypnotic marshmallow mounds of Renee’s flesh. Instead, it is a moving story about one woman’s poor diet, low self-esteem and personal misfortune.
