This new show bandies about the f-word - fat - with fearless abandon. "Watch out massive fatties. The lard police are in town," thrills weight-loss expert Steve Miller as he sets out to change the grazing habits of six families. This week, he calls on the Shropshire home of the corpulent Cuff clan. Gran Anna is 22 stone, dad Mike 24 stone, while wife Tarnya weights 33. She loves being fat but admits, "You can be too fat to live." Get past the close-ups of grup being gobbled, and it's a heartening, often funny, cautionary tale of people in need of guidance.
