Michael Hugh Mosley (22 March 1957 – 5 June 2024) was a British television and radio journalist, producer, presenter and writer who worked for the BBC from 1985 until his death.

[5][6] His maternal grandfather, Arthur Dudley Stewart, was an Anglican priest and Principal of St. Paul's College, Hong Kong, born to Irish missionary parents in China.

[4] After graduating in medicine, Mosley elected not to pursue a career as a doctor, but instead joined a trainee assistant producer scheme at the BBC in 1985.

[12] His career in front of the camera began in 2007, when he pitched a series for BBC television titled Medical Mavericks and, unable to find a suitable host, offered to present it himself.

[3] He went on to present numerous programmes for TV, including Blood and Guts, The Story of Science, Make Me, and Trust Me, I'm a Doctor.

These programmes described the recent medical advancements that allowed for improved treatment of military personnel injured in battle in Afghanistan, and examined how these new techniques were being used in emergency medicine in civilian casualties in the United States and Great Britain.

His own genetic type can gain many of the benefits of exercise, primarily improved insulin response, through short, high-intensity training sessions as suggested by the research of James Timmons.

[19][20][21] Mosley, along with a group of medical specialists, presented a BBC Two documentary series titled The Diagnostic Detectives which aired in 2020.

This advice was considered dangerous by some medical experts and the programme received criticism on social media platforms.

[25] Mosley presented the series Just One Thing on BBC Radio 4, in which each episode explored a single action a person could take to improve their health.

Suggestions covered a wide range including reading poetry out loud,[26] taking hot baths in the evening,[27] playing a musical instrument, Nordic walking, and cooking tomatoes to increase their health benefits.

[45] Red Pen Reviews gave Mosley's book The Fast 800 Keto a score of 58% for scientific accuracy, but concluded that the diet "should cause weight loss and improve health in most people who have extra weight and/or type 2 diabetes, but some aspects of the diet may be unnecessary and make it harder to follow".

[57] An initial post-mortem established that, based on the position of his body and the lack of any fatal injury, Mosley had likely died from natural causes at around 4 pm on the day he disappeared.
