Is it ok to stay on weight loss injections?

They have been nothing short of a pharmaceutical phenomenon. But for people like listener Lynn who've had huge success on weight loss drugs like Mounjaro, the question now arises about the implications of using them long-term. Could there be a 'maintenance' dose that would potentially allow for use over many years, or even a lifetime? And as scientists study the data, are other benefits emerging that go beyond just losing weight that could burnish their wonder-product reputation?

Presenter Greg Foot is joined in the studio by Lynn to hear her story and do a deep-dive into the science alongside Professor of Molecular Neuroendocrinology at the University of Cambridge, Giles Yeo.

Why did Skype fall out of favour in a world of global video calls?

The BBC Business journalist, Sean Farrington, investigates with the entrepreneur, Sam White, alongside him.

Sam never knows what's coming so, at the end of every episode of Toast, she gives her off-the-cuff and authentic professional opinions on why a brand disappeared based on what she has just heard and her own business knowhow.

In this episode, we learn how Skype worked by using Voice Over Internet Protocol to send audio and video data over the internet. It connected users through a centralized, cloud-based service which allowed free voice and video calls between Skype users.

It really changed the game when it came to keeping in touch with friends and family around the world. It helped grandparents meet their grandchildren for the first time without leaving the house and gave us a way of cutting our phone bills.

Sean interviews:

- Peter Raeburn - an award-winning composer who worked with Skype’s founders to create the iconic sounds that became the familiar sound track to Skype which, at its peak, was used by over 300 million people worldwide.

- Andrew Sinclair - a General Manager for Skype for Business who offers his insight into what happened after Skype was sold by Ebay, and snapped up by tech giant, Microsoft.

-Sam Shead - a journalist who witnessed how Skype changed the world of communication, soaring and then sinking and has taken an in depth look at the names behind the brand, so what did he uncover?

Dasani water, a bottled water from Coca-Cola, proved a big hit in the U.S.A so why did it last for less than 6 weeks in the UK?

The BBC Business journalist, Sean Farrington, investigates how it ended up toast, in the company of resident business expert and entrepreneur, Sam White.

In the early 2000s, Coca-Cola had entered the growing bottled water market and was hoping to turn its hit new brand in America into a global sensation.

But shortly after Dasani water was launched in the UK, things quickly went awry, derailing plans for expansion into Europe.

To help explain what happened, Sean and Sam delve into the BBC archives and hear from expert guests including Graham Hiscott, the journalist whose story shone a new light on to the brand, and Conor Carroll a lecturer and marketing expert who has written about the Dasani debacle.

They also hear from Toast listener, Chris Leversha, who remembers buying Dasani water and suggested we cover it on the show.

At the end, Sam has to come up with her own professional conclusions about the fate of Dasani UK based on what she has just heard.

How did the company behind the revolutionary BlackBerry smartphone lose its grip on the handset market?

The BBC Business journalist, Sean Farrington, investigates with special guest, Sir Stephen Fry, who has remained 'faithful' to the BlackBerry brand.

Alongside them is the entrepreneur, Sam White, who at the end of the show has to reach her own conclusions on why BlackBerry handsets disappeared, based only on what she has just heard and her own business acumen.

The first BlackBerry device freed business executives from their desks, allowing them to easily write, send and receive emails from almost anywhere. But that was not the only thing that made the BlackBerry, and its later iterations, extraordinary.

The actor, comedian, author and broadcaster, Sir Stephen Fry, also used to be a tech blogger and wrote in glowing terms about BlackBerry devices...until they took a turn for the worse.

Stephen explains why he was disappointed by a brand he loves and how he still hopes it might make a return.

Jim Balsillie was a co-chief executive officer at Research in Motion, the company that created BlackBerry, and offers his insight into how it quickly became a $20billion business and why he felt compelled to resign from such a tremendously successful venture.

The entrepreneur and tech blogger, Kevin Michaluk, witnessed how BlackBerry handsets soared and then sank. He's made a successful career out of building "spiritual successors" to them but can his attempts to bring them back under the original brand prove successful?

The podcast version of this episode, available on BBC Sounds, includes a bonus interview at the end with Sir Stephen Fry on how he feels about technology and social media today.

Are special shampoos and coatings any good at cleaning and protecting your car?

They're all over Instagram: washes, foams, and ceramic coatings in a rainbow of coloured bottles that promise to give your car that showroom shine. For listener James - a driving instructor - the question is whether they're worth the money, or if an ordinary bottle of washing up liquid will do the job.

Listener Julie has been reaching for the fake tan every spring to add a "bit of colour" to her legs, but after much trial and error with foams, lotions and gels, she got in touch with Sliced Bread to ask what is actually IN fake tan? How does it work - and is there a particular kind that might suit her best?

Greg Foot is joined by Consultant Dermatologist and Senior Lecturer at the University of Manchester Dr Jean Ayer, as well as Cosmetic Scientist and Science Communicator who runs the blog LabMuffin Dr Michelle Wong, to find out.
