A series fronted by Michael Mosley, which includes a special tribute from his widow, is to air on Channel 5.
The broadcaster and columnist died of natural causes in June, aged 67, after he went missing on the Greek island of Symi.
The three-part series, Michael Mosley: Wonders Of The Human Body – which will air later in the month, will see Mosley investigate the human body and understand how it changes as we age.
His widow Dr Clare Bailey Mosley said: “One of Michael’s biggest passions has always been to reveal the extraordinary secrets of how our bodies work, to help us understand and look after them.
In episode one, Mosley travels to Dundee, where he meets tremor sufferer Thomas who is about to undergo pioneering brain surgery.
Then in Southampton, Allen finds out if his experimental cancer treatment has been a success and Mosley reveals the health benefits and risks of cold water swimming, also looking at a state-of-the-art test that could help predict heart problems years in advance.
Mosley is credited with popularising the 5:2 diet, a form of intermittent fasting, through his book The Fast Diet, and he often pushed his body to extreme lengths during his research into health and wellbeing.
He first trained as a doctor in London before moving into the world of media – becoming a presenter, documentary maker, author and columnist.
During his career, he presented a host of science programmes and films including the BBC series Trust Me, I’m A Doctor, which looked at healthcare in Britain, and hosted BBC Radio 4 podcast Just One Thing.
In July, the BBC honoured Mosley with a day dedicated to him where presenters and audiences where encouraged to do “just one thing” to improve their wellbeing.
Michael Mosley: Wonders Of The Human Body will air on Channel 5 on August 22 at 8pm.
