The documentary was about "Four overweight Brits, addicted to fast food meals, take the road to Pakistan, where they are welcomed by a community of shepherds, who use the same diet for thousands of years. It remains to be seen whether the four Europeans will be able to break bad habits and learn to eat healthy and unexpectedly delicious." (source)
"The four Brits will go 'cold turkey' as they swap chicken nuggets for goat; pizzas for super lean yak; and tinned ravioli for apricot soup. It's a nutritionally balanced, optimal diet which has resulted in locals living to a ripe old age, free from obesity related diseases like diabetes, heart disease and cancer; but to our Brits - who fail to consume five fruit and veg a month, let alone a day - the diet will be tasteless, monotonous and downright unpalatable."

At first this might sound a bit extreme for them, but in time they realise that food actually tastes very good and their senses just needed a "retraining" :)
Their whole life is changed by this experience. It is wonderful to see how an experience like this changes gradually the life of a person in a positive way.
