TikTokers sure like to up the ante on their health fads. Just when you thought you were doing enough reps, walking enough steps and adjusting your shower temperature to sufficiently freezing lows, they spring a new challenge on you.

The latest trend is 30-30-30, a method that involves eating 30g protein within 30 minutes of waking up, shortly followed by 30 minutes of cardio. Proponents believe this enables slow and steady weight loss. We asked a nutritionist to check the facts. And while she says the jury is out on the weight loss claims, she does suggest that this way of starting the day could be a great option for people trying to incorporate healthy habits into their lives.

With news that Pope Francis has recognised two miracles attributed to Carlo Acutis, a teenager who died in 2006, the Catholic Church is on the way to having its first millennial saint. We wondered how all this actually works in the 21st century, since we’re more used to sainthood being associated with ancient relics and dimly lit paintings on cathedral walls. Liam Temple, a specialist in the history of Catholicism, looks at what is different about canonisation in the digital age, a process which apparently includes a livestream of people visiting your remains.

I remember a man tried to sell me 500g of Cathedral City in a pub once, and at the time I thought it was random and hilarious to see someone bootlegging cheddar. But I now realise the black market in stolen food is big business. It’s also a highly destructive force in a market already struggling with supply chain problems and soaring costs, and may contribute to driving up prices for consumers.

Also this week, how to decide if it’s time to quit therapy, why Rishi Sunak has quite the nerve ordering teenagers into national service and what to expect from US voters now Donald Trump is a convicted felon.
