Listener Steve got in touch with us after trying out a set of Smart Scales himself. He wanted to keep an eye on his protein levels – which his scales claimed to do – for health reasons, and because he’d heard that we need more protein as we get older. His scales also promised to show him his body fat, muscle mass, and bone mass via a corresponding app on his phone. However, some of those readings didn’t seem quite right – making him question how accurate his scales are, and if they can REALLY tell you so much about yourself? Greg Foot asks two experts - a GP and a professor of applied mathematics – to weigh in on the topic, and find out whether these scales can measure up. As always, all of our investigations start with YOUR suggestions. If you’ve seen an ad, trend or wonder product promising to make you happier, healthier or greener, email us at sliced.bread@bbc.co.uk OR send a voice note to our WhatsApp number, 07543 306807.

Smart Scales

While Sliced Bread takes a break we serve up Toast. A study of the spectacular failures of brands which had promised so much to consumers. In each episode, the presenter and BBC business journalist Sean Farrington examines one big idea. What did it promise? Why did people back it? Why did they get burnt? Some of the world’s most successful businesses have also brought us some of the world’s most remarkable failures. So, what led them to be toast? And what can we learn from their stories today? Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently? The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand’s fortunes and reaching her own, often instructive, conclusions. From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked. Sliced Bread returns for a new batch of investigations in January, 2026. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds. For this brand new series of Toast, episodes will be released weekly on Thursdays wherever you get your podcasts. But if you’re in the UK, you can listen to the latest episode on BBC Sounds first, a week earlier than anywhere else.Toast is a BBC Audio North production for BBC Radio 4.
