Copyright: Jo Murphy - KEO Films Hugh Fearnley-Whittingstall turns his attention to the fruit juice and smoothie sellers. He’s surprised to learn bottles of fruit juice can contain as much free sugar as a can of fizzy pop, but that it is not clear on the labels, and that most people he meets in the street have no idea. He is also confused that these labels seem to suggest that anything up to 330ml is a single portion size, when in fact the government recommends not drinking any more than 150ml of juice or smoothies a day.

Three months in, Hugh’s attempt to change the eating habits of a whole city has got off to a slow start … but with Ross Noble’s help it soon starts to take off. Jonny, a local bus driver who wants to lose weight for his children, is given some shocking news when he is diagnosed with Type 2 diabetes. This inspires Jonny to make big changes to his lifestyle, which culminates with him running the Great North Run 5k with Hugh and a big group of other members of Newcastle Can.

Children are eating out twice as much as they did in the 1970s, so Hugh puts the spotlight on our most popular high street restaurant chains. He challenges them to reduce the amount of sugar in their puddings, to carry calorie information on their children’s menus and to stop selling bottomless fizzy drinks… When he lets them know there is a window of opportunity to do something before a league table is published, ranking the top 25 from best to worst, some make significant changes. The result is that 10 restaurant chains are now selling 6 million healthier kids’ meals a month.

In this episode, Hugh looks at junk food marketing versus the amount that is spent on vegetable marketing and healthy eating, and he’s shocked by the results. When Hugh helps get healthy adverts up in schools and in shops across the country, the results are inspiring.

Hugh also learns that there are some simple and obvious changes which could be made to GPs surgeries that could help prevent obesity-related diseases, like putting weighing scales in every GP waiting room and making it mandatory to weigh every patient before they see the doctor. Hugh arranges a trial in Bristol, with dramatic results.

In Newcastle, Hugh meets Janet, who signed up to Newcastle Can but is finding it difficult to lose any weight. Hugh wants to see if she can make changes to her lifestyle by getting outside of her comfort zone, so they head to the beach to go surfing.

At the end of Hugh’s year-long mission to put the city on a diet, he meets up with some of the people who have already achieved life-changing weight loss and discovers if his ambitious 100,000lb target has been reached.

But it’s becoming clear that he can’t do it all alone. Hugh wants to know what the government is doing about it. Hugh heads to Tory Party Conference, where he has been invited to speak about obesity, but is frustrated in his attempts to get an audience with Jeremy Hunt.

So with the help of Jamie Oliver, Hugh comes up with a bold plan to try and improve the health of our nation once and for all… but he can’t do it alone, and he needs everyone in the country to get involved…

In this final showdown, he examines some of the misleading marketing claims on 'healthier' products, unveils the truth about why Brits love to snack and challenges a family to rethink their portion sizes. And, after almost 100,000 people sign Hugh's letter to the health secretary, he finally gets the interview he has been after for months, discovering some exciting changes that are on the horizon.

British people snack more than any other European country and since the last series aired, lots of people have told Hugh about the foods they find irresistible. To find out more, he runs an experiment to uncover which snacks have Britons hooked and discovers a surprising new theory about one particular combination of ingredients people cannot help but find irresistible.

One of the main drivers of obesity is the simple fact that people are all eating too much. Hugh visits a Torquay family where the father wants help with his diet to stay healthy for his daughters and shift some pounds. Hugh challenges the family to transform their eating habits with a few simple and memorable tricks to reduce the portions on their plates.

Hugh heads to Westminster with Jamie Oliver to talk to MPs about the obesity crisis. He gets the chance to put his questions directly to the health minister and sees many of the issues he has raised throughout the series addressed in some exciting announcements - but are they going to be enough?

In a final fight back against fat, Hugh sees the 'veg power' advertising campaign go to a whole new level, in the hope it will change kids' attitudes to vegetables once and for all.
