Si King and Dave Myers come up with a fat-friendly pie for fellow dieter Ann, baking a pastry treat that comes in below the 700 calories of a standard pork pie - but keen to lose as much weight as they can, they don't taste it themselves. Moving on to Dave's home town of Barrow-in-Furness in Cumbria, the duo try to persuade the diners in Chinese and Indian restaurants that their favourite dishes can be even better with all the fattening elements removed.
