Jamie and the team reveal how a diet high in fat, sugar, salt and empty calories, and low in nutrients and vitamins, is a major risk factor for life-threatening conditions such as heart disease, cancer and diabetes. And Dr Gunther von Hagens conducts an autopsy to graphically reveal the terrible damage the volunteers' poor diets are doing to them, from straining over-sized hearts and damaged livers, to clogged arteries and organs smothered in fat. Meanwhile Jamie offers hope and shows the simple, effective steps we can all take to eat better and live longer. But can the volunteers ditch their bad diets and stop killing themselves?
