第 1 季，第 1 集: The eight Brits arrive in Namibia, leaving their lazy fast food lifestyles 5000 miles behind them to live for three weeks with the Bushmen of the Kalahari. 17 stone Louise (clinically obese) has only once in four years walked the ten minutes to her corner shop. Here she must walk miles in the search for food. 20 stone Oxford post grad Martin (morbidly obese) quickly learns the merits of butchering the protein rich kudu, a kind of antelope, but not how to hold his tongue. 18 1/2 stone single mum Dionne (morbidly obese) is a binge snacker used to eating every couple of hours, day and night. As the detox from her western diet kicks in she’s quickly at loggerheads with the usually mild mannered 13 stone Melissa (clinically obese), who’s only passing acquaintance with vegetables back home is with the lettuce she feeds her pet rabbits. Before the Brits learn to hunt for themselves (when elephant and porcupine could be on the menu as well as antelope and guinea fowl) they will live on a predominantly vegetarian diet of nuts and berries. Under the watchful eye of nutritionist Alice Sykes and tribal elder !Amace the obese westerners struggle from day one to come to terms with a diet that they quite literally find hard to swallow.
