A new update on the late Dr Michael Mosley’s Instagram account pays tribute to him, as well as sharing a previously-filmed clip of the health expert. In the post’s caption, fans are urged: “Let’s carry on Michael’s incredible work by embracing the power of one small change and sharing it with those around us.”

Dr Mosley was well known for TV appearances, and for creating diet plans such as the 5:2 and the Fast 800. As well as this, he also authored a number of books, and hosted popular podcast – Just One Thing.

In the series, the expert regularly shared simple tips people could use to improve their health and change their lives. In the clip shared on social media on Friday, the late doctor could be seen saying: “People often ask me what is the single ‘Just One Thing’ that has made the biggest difference to my life, and I think it is probably learning to do slow, deep breathing.

“It’s called 4-2-4, you simply breathe in to a count of four, hold it for two, and then out to a count of four. If you do that for a minute or so, you’ll feel everything calm down and it’s particularly effective in the middle of the night.”

The post’s caption further reads: “Today, we reflect on his incredible life and work – an inspiring doctor, researcher, and storyteller who changed the way we think about health. From his pioneering research on intermittent fasting to his approachable and impactful health advice, Michael’s mission was clear: to make wellness simple, accessible, and sustainable for everyone.

“Through his Just One Thing series, Michael showed us that small, manageable changes can lead to profound improvements in our health and well-being. Whether it’s prioritising sleep, adding more movement into our day, or deep breaths, his approach proved that consistency in the small things can truly transform lives.

“Even though Michael is no longer with us, his legacy lives on through his work. Just One Thing continues to inspire us to make positive changes in our lives—one simple step at a time.

“And through his books, TV programs, and all the people he’s helped along the way, we can still share his wisdom and empower others to live healthier, happier lives.”
