Before the Brits learn to hunt for themselves they must live on a predominantly vegetarian diet of nuts and berries. Nutritionist Alice Sykes and tribal elder Amache look on as the obese Westerners struggle from day one to come to terms with a diet that they quite literally find hard to swallow.
The Brits' distaste for the hunter-gatherer menu turns to revulsion and, for some, a complete food boycott. Single mum Dionne is at loggerheads with Oxford-educated Martin until mutual self-interest bonds them in the search for a new source of food, grubbing underground for the potato-like shah.
The tough lessons prove too much for some and just halfway through the experiment eight are about to become five. Martin finds himself hungry, disillusioned and verbally violent. Facing his food demons has made him mad with rage and he decides to abandon the experiment, followed by two others.
The women have outlasted and outshone the men in their adaptation to the rigours of bush life, and their success in trapping now regularly puts guinea fowl on the menu. But the team is dealt another blow with the emergency evacuation of Melissa, who has a suspected deep vein thrombosis.
