Michael Mosley (born 22 March 1957) is a British television journalist, producer and presenter who has worked for the BBC since 1985. He is probably best known as a presenter of television programmes on biology and medicine and his regular appearances on The One Show. Mosley is an intermittent fasting and low-carbohydrate diet advocate who has written books promoting the ketogenic diet. He is not a dietitian.

Early life

Mosley was born in Calcutta, India. His father was a banker and his maternal grandfather was a anglican bishop. Mosley attended a boarding school in England from the age of seven. He studied Philosophy, Politics and Economics at New College, Oxford, before working for two years as a banker in the City of London. He then decided to move into medicine, intending to become a psychiatrist, studying at the Royal Free Hospital Medical School, now part of UCL Medical School.

Career

Upon graduation from medical school, and having become disillusioned by psychiatry, Mosley joined a trainee assistant producer scheme at the BBC in 1985.

He produced a number of science programmes, including The Human Face, three series with Professor Robert Winston, and the 2004 BBC Two engineering series Inventions That Changed the World hosted by Jeremy Clarkson. He presented Blood and Guts, Medical Mavericks and The Story of Science for television, and was the subject of a television documentary, 10 Things You Need to Know about Losing Weight. He presented Make Me for BBC One. In April–June 2010 he produced and presented the television series The Story of Science: Power, Proof and Passion broadcast by BBC Two.

In 2011 he made a series entitled The Brain: A Secret History, on the history of psychology and neuroscience. During the series, while describing the methods that are being employed to identify the anomalies in brain structure associated with psychopathy, his personal test results revealed he himself had these candidate brain characteristics. In the same year, he made a two-part documentary, Frontline Medicine with episodes called "Survival" and "Rebuilding Lives". These programmes described the medical advances in the treatment of military personnel during the 10 years of war in Iraq and Afghanistan and examined how these new techniques are being used in emergency medicine in civilian casualties in the United States and Great Britain.

His documentary The Truth About Exercise, shown first in 2012, aired current thinking about how different patterns of exercise might help achieve health benefits, the danger of sitting for prolonged periods and revealed how certain genotypes are unable to gain significant improvements in aerobic fitness (VO₂ max) by following endurance exercise programmes. 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 Professor James Timmons.

In January 2013, he presented The Genius of Invention. In the documentary named The Truth About Personality, first aired on 10 July 2013, Mosley explores what science can tell us about optimism and pessimism and whether we can change our outlook.

Mosley, along with a group of medical specialists, presented a documentary series titled The Diagnostic Detectives which aired in 2020. In the series, each programme is centred around the group of doctors who choose to tackle a patient's problem. In 2021, Mosley presented a three-part series, Lose a Stone in 21 Days for Channel 4. On the programme Mosley asserted that people can lose a stone in 21 days by calorie restriction to only 800 calories a day. This advice is considered dangerous by medical experts and the programme received a backlash on social media platforms. Beat, a UK charity supporting those affected by eating disorders, stated that "the programme caused enough stress and anxiety to our beneficiaries that we extended our Helpline hours to support anyone affected and received 51% more contact during that time".

Intermittent fasting and low-carbohydrate diet advocacy

Mosley promotes intermittent fasting and is a low-carbohydrate diet advocate.

5:2 diet

Mosely is credited with popularising a form of intermittent fasting called the 5:2 diet though an episode of the BBC documentary series, Horizon called, Eat, Fast and Live Longer. It was through this documentary that he learned about the 5:2 from scientist Mark Mattson who published a paper on the 5:2 with Michelle Harvie and 14 other scientists in 2011. In the original trials, the 5:2 does not follow a particular food pattern, but instead focuses entirely on calorie content. It became very popular in the UK and Australia.

In early 2013 Mosley published The Fast Diet with Mimi Spencer.

The Fast 800 diet

Currently, Mosley advocates The Fast 800 Diet, a low-carbohydrate Mediterranean diet with intermittent fasting that follows a daily 800-calorie eating plan. His book The Fast 800 Keto combines a ketogenic diet with intermittent fasting.

Mosley's The Fast 800 Keto advises a three-stage diet plan for weight loss, including stage 1 a very low-carbohydrate ketogenic diet, stage 2 a reintroduction of carbohydrates with intermittent fasting and stage 3 a low-carbohydrate Mediterranean diet. Mosley has stated that a downside to the ketogenic diet is that it is restrictive so his Fast 800 Keto solves this problem by gradually allowing carbohydrates back into the diet for a long-term low-carbohydrate Mediterranean diet.

Red Pen Reviews noted that Mosley's book The Fast 800 Keto "scored weakly 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". The review also noted that Mosley's Fast 800 Keto is not a long-term ketogenic diet and the insistence on a low-carbohydrate intake for the long-term Mediterranean diet is not necessary.

Television

Awards and honours

In 1994, Ulcer Wars, his 16 May 1994 Horizon documentary, reported the link between Helicobacter pylori and gastric ulcers, discovered by Australian scientists Robin Warren and Barry Marshall. He was named Medical Journalist of the Year in 1995 by the British Medical Association. In 1996, the programme was noted as one of the most important factors to influence British general practitioners' prescribing habits.

In 2002, Mosley was nominated for an Emmy as an Executive Producer for The Human Face with John Cleese.

Personal life

Mosley is married to Clare Bailey, a GP; they have four children. In a BBC documentary on sleep, Mosley revealed he has chronic insomnia. He published Fast Asleep in 2019.
