Ella Mills is the best-selling food writer and founder of Deliciously Ella, the food blog-turned-brand which she created in 2012 after a sudden debilitating illness led her to overhaul her diet and turn to plant-based foods as a way to get better.

Since then, Mills has become a key player in bringing healthy food to the mainstream, with a brand whose 100 plant-based, additive-free products are now sold in all major UK supermarkets, and whose revenue is estimated to be £20 million. But this huge success has come with vicious trolling and personal attacks online - and it’s only now that Mills has finally come to terms with it.

Today on Ways to Change the World, she tells Krishnan Guru-Murthy about the story behind Deliciously Ella, why a change in our diets towards more fresh, plant-based foods cannot happen unless the government steps in, and acknowledging the difference between her privilege and her business success.

Despite being 76 years old, Arnold Schwarzenegger shows no signs of stopping.

The bodybuilding champion turned Hollywood star turned US politician, now in the ‘fourth act’ of his life, has reinvented himself into a motivator, and written a book, ‘Be Useful: Seven Tools for Life’, about guiding people to achieve a ‘happy, successful, useful life’, inspired by his singular American experience.

Today on Ways to Change the World, Arnold Schwarzenegger tells Krishnan Guru-Murthy how he can ‘be useful’, why world leaders are failing to resolve the Israel-Palestine conflict and why America needs a new candidate to enter the presidential race.

From 2019 to 2021, Samuel Kasumu was the most senior Black advisor in Downing Street, and was widely referred to as Boris Johnson’s racism advisor, working alongside the former Prime Minister during the first half of the Covid pandemic.

Kasumu left Downing Street in April 2021, amid the fallout from a UK government report that dismissed institutional racism. It wasn’t until after leaving his position, he says, that he realised how much of an ‘outsider’ he was, as a Black, working-class man who did not go to Oxbridge.

In this week’s episode of Ways To Change the World, he talks to Krishnan Guru-Murthy about the reasons why he first joined the Tory party aged 19, the role of special advisors in No 10 and why culture wars inside Downing Street made the downfall of Boris Johnson ‘inevitable’.

Keith Allen has been many things. The father of popstar Lily and Game of Thrones actor Alfie Allen, he was also a TV presenter, theatre actor, the man behind two hit football anthems (the Fat Les ditty “Vindaloo” and New Order’s “World in Motion”, both of which he co-wrote) and a handful of small roles in cult movies (Shallow Grave, Trainspotting, 24 Hour Party People).

Growing up, he was a troublemaker; he’d spent time in Borstal, was thrown out of drama school, even sent to prison. 

Now in his 70s, as he prepares to star in a new musical called Rehab, he looks back on the moments that have made up his rollercoaster life and career with Krishnan Guru-Murthy, on this week’s episode of Ways to Change the World.

Billy Porter started singing in church when he was about five years old, and growing up saw performance as a lifeline out of the trauma and rejection he experienced as a Black gay man.

The multi-hyphenate star won a Grammy and a few Tonys since his breakout role on Broadway with 2013's Kinky Boots, and was the first openly gay Black man to win a lead acting Emmy for his role in the drama series Pose in 2019. Now Porter is returning to mainstream music with his fifth studio album, Black Mona Lisa, which he hopes will continue to craft an empowering legacy for the queer youth of colour.

Today on Ways to Change the World, he tells Krishnan Guru-Murthy about the challenges he faced due to homophobia in the music industry in the '90s, the harsh reality of being an actor in the golden age of streaming and what success means to him.

Being an astronaut is a job like no other. Of the estimated 100 billion people who have ever lived, only 628 people in human history have left Earth.

Tim Peake is one of them. A former test pilot who served in the British Army Air Corps, he was the first British astronaut to ever walk in space, and completed his six-month Principia mission to the International Space Station with the European Space Agency when he landed back on Earth in June 2016.

Today on Ways to Change the World, he tells Krishnan Guru-Murthy about his journey to becoming an astronaut, his time on the ISS and the crucial role of Elon Musk and SpaceX in future space missions.

Caster Semenya has never doubted that she was a woman. It wasn’t until her athletics career started to take off that the now two-time Olympic Games gold medallist and a three-time World Athletics Championships gold medallist faced any questions over her gender. Called a ‘threat to the sport’ and ‘not woman enough’, she has become the most visible DSD (difference in sex development) athlete today, and found herself at the centre of the debate around the newly drawn line between gender and sport.

In this episode of Ways to Change the World, she tells Krishnan Guru-Murthy about her experiences as an athlete with a difference in sex development, her tumultuous journey to the top of the athletics world, and what being a woman means to her.

It is nearly two weeks since Israel launched its ground offensive into Gaza and more than a month since it began intensive air strikes against Hamas, following the brutal attacks in Israel in which more than 1,400 people were killed.

ActionAid is one of the many charities responding to the humanitarian crisis in Gaza, and its UK CEO Halima Begum is urging countries that finding a humanitarian solution is paramount, with thousands of civilians dead and the majority of Gaza's 2.3 million residents having been displaced.

Today on Ways to Change the World, Halima Begum tells Krishnan Guru-Murthy about her journey from youth activism to NGO work, the West’s ‘moral responsibility’ to humanitarian aid and the need for an immediate ceasefire in the Israel-Palestine war.

Carlo Rovelli has devoted large parts of his life to explaining to the general public what appears on the surface to be the unexplainable - and his bestselling science books saw him dubbed 'the poet of modern physics’.

But the quantum gravity researcher is as comfortable discussing his own work on black holes, as he is talking about recent politics such as the Israel-Palestine conflict, on the grounds that, like in scientific research, every issue has different facets and cooperation is key to finding a solution.

Today on Ways to Change the World, Carlo Rovelli tells Krishnan Guru-Murthy about his search for ‘white holes’ and how science can bridge different global narratives in the geopolitical arena.

The climate crisis is the biggest single issue affecting us all - but for some, the impact will be, and already is, far greater than for others.

This is the principle of climate justice, that sees the causes and consequences of climate change as inextricably linked with social inequality - and that activist Mikaela Loach has made the focus of her work.

Today on Ways to Change the World, Mikaela Loach tells Krishnan Guru-Murthy why we need to reframe our understanding of the climate crisis in order to tackle its root causes, and why only through “active hope” and collective action can we radically transform our world for the better.
