Start the Week - Weighty issues

Over the past 50 years, worldwide obesity rates have tripled, and now headlines increasingly shout of a public health crisis, even an obesity epidemic. Tom Sutcliffe explores the consequences of using such negative and emotional language to describe weight and the increasing rates of fat phobia in society. He looks at the health issues and the so-called ‘miracle drugs’ that suppress appetite, and where genetics and diet meet.

He’s joined by Naveed Sattar, Professor of Metabolic Medicine at the University of Glasgow and recently appointed as the UK Government’s Obesity Mission Chair, the body-positive activist Stephanie Yeboah who’s the author of Fattily Ever After, and the businessman Henry Dimbleby whose book Ravenous reveals the mechanisms behind our food systems.

The Gatekeepers - 4. Flood the Zone

2016 is a big election year. But something is going very wrong online. Journalists in America and the Philippines start to notice something strange going on online.

In Manila, Maria Ressa - the editor of online news site, Rappler - discovers a sock puppet network of social media accounts, all pushing for the election of a strong leader. Someone like Rodrigo Duterte. Maria is suspicious. She makes an urgent call to Facebook.

In Veles, in Macedonia, a young man called 'Marco' starts writing fake articles and posting them online. Very soon they're being read by millions of people around the globe and he's making huge sums of money.

The online ecosystem is under attack.

More or Less: Behind the Stats - NBA basketball: Is height more important than skill?

In the NBA, the US professional basketball league, the average player is a shade over 6ft 6 inches tall. So just how much does being very tall increase a man?s chances of becoming a professional player?

Start the Week - Arts: changing the world?

The journalist and broadcaster Ellen E. Jones explores the immense potential of film to challenge the status quo in her book, Screen Deep: How Film And TV Can Solve Racism And Save The World. She explores different genres from superheroes and westerns to horror and arthouse. And she argues that such a popular art form - either shared in the cinema, or beamed direct into your home – revels in the diversity of its story-telling.

The Iranian-Australian filmmaker Noora Niasari has chosen to draw from her own personal experience in her debut feature, Shayda (open in cinemas across the UK & Ireland on Friday 8th March 2024). Set in a women’s shelter, the film explores what it means for an Iranian woman to divorce her husband and fight for a new life for herself and her child.

But what about other art forms and the stories they tell? The Royal Academy’s latest exhibition – Entangled Pasts: Art, Colonialism and Change (until 28th April) – places work from the 18th century alongside contemporary work to explore how art, both old and new, is entangled with and reflected by Britain’s colonial past. Hew Locke will be showing his major work, Armada, which consists of a giant flotilla of model boats.

The Gatekeepers - 3. Are You Not Engaged?

The tech pioneers were right: all this connectivity and sharing is creating a new age of freedom and democracy. A global consciousness.

Arab Spring, Barack Obama – both fuelled by social media - make the possibilities feel limitless.

But, just as the dream to connect everyone is being realised - at the height of technological optimism - everything starts to fall apart.

Big medical datasets pose a serious problem. Thousands of patients? health records are an enormous risk to personal privacy. But they also contain an enormous opportunity ? they could show us how to provide better treatments or more effective health policies.

A system called OpenSAFELY has been designed to solve this problem, with the help of a computer code ?robot?.

Professor Ben Goldacre, director of the Bennett Institute for Applied Data Science at the University of Oxford, explains how it works. Presenter: Tim Harford Producer: Tom Colls Production co-ordinator: Janet Staples Sound mix: Hal Haines Editor: Charlotte McDonald
