First up this week is luxury weight-loss and detox retreat Slimmeria, owned by Galia and Michael Grainger. Health fanatic Galia's mission is to spread the Slimmeria message. But what do fun-loving Ann and Bill Clay from Bosvean House make of Galia's £260 price tag, rules and regulations, and 9pm curfew? Jan and William from St Giles are happy to comply, but Diane and Max from Ombersley Bed & Breakfast suspect they're in for an uncomfortable night ahead when they sample the bed. An afternoon work-out, Zumba-style, followed by a healthy meal and weight-loss lecture does little to get the party started.
