Aseem Malhotra

In September 2022, Malhotra publicly campaigned against the use of COVID mRNA vaccines. An AFP factcheck warned of his claims:

Malhotra initially campaigned in favour of taking the COVID vaccine. Later however, he campaigned against the use of COVID mRNA vaccines contrary to the available evidence. In November 2021, Malhotra appeared on GB News to discuss an abstract for an academic poster published by Steven Gundry and which the American Heart Association had warned may contain "potential errors". Malhotra claimed that the abstract supported "a significantly increased risk from 11% at five years, the risk of heart attack, to 25%." after taking mRNA vaccines against COVID-19. Full Fact warned that "Serious concerns have been raised as to the quality of the research".

In 2020 during the COVID-19 pandemic and before there were any approved vaccines for COVID-19, Malhotra published a book claiming that following his dietary advice could grant "metabolic optimization" which would, in 21 days, decrease the risk of viral infection. David Gorski criticized the book because the biggest single risk factor for COVID-19 infection is age, which people cannot change. Gorski said that while Malhotra had a germ of a good point and that it was undeniable that losing weight for someone who is obese would reduce their risk of complications, the claims about the book were massively exaggerated and there was no specific evidence for the impact of lifestyle recommendations on the risk of COVID-19 or that Malhotra's version of a healthy diet was better or worse than any other healthy lifestyle recommendation. Gorski was also concerned that telling people that they should be in control of their susceptibility to disease may have an element of victim blaming because that shifts responsibility for disease onto individuals, many of whom are unable to follow the kind of diet Malhotra advocates.

His views on diet and health have been criticized by the British Heart Foundation as "misleading and wrong", and his public questioning of the need ever to use statins has been condemned as a danger to public health. His "Pioppi diet" was named by the British Dietetic Association as one of the "top 5 worst celeb diets to avoid in 2018". During the COVID-19 pandemic, Malhotra published a book called The 21-Day Immunity Plan, which claims that following the diet can quickly help people reduce their risk from the virus; such claims are not backed by medical research evidence. Despite initially campaigning for the COVID vaccine, he later campaigned against the use of COVID mRNA vaccines contrary to the available evidence.

The Pioppi diet was listed as one of the "top 5 worst celeb diets to avoid in 2018" by the British Dietetic Association. According to the BDA and others, it is a new spin on a low-carb high fat diet that "hijacked" the term Mediterranean diet: substituting cauliflower for rice or pizza base and cooking with coconut oil are not parts of the traditional diet of the villagers of Pioppi.

Malhotra is a proponent of fad diets such as low-carbohydrate diets and in 2017 he co-authored a low carb diet book called The Pioppi Diet, which provides a 21-day eating plan. Malhotra's personal royalties from the book are donated to charity. The book recommends the daily consumption of two to four table spoons of extra-virgin olive oil, a small handful of tree nuts, five to seven portions of fibrous vegetables and low sugar fruits and oily fish at least three times a week. It advises people to avoid all added sugars, fruit juice, honey, and syrups, packaged refined carbohydrates, in particular anything flour based including all bread, pastries, cakes, biscuits, muesli bars, packaged noodles, pasta, couscous and rice and seed oils. Very dark chocolate, butter, coconut oil, cheese, yoghurt are allowed. The moderate consumption of alcohol is allowed but only within the limits set by the NHS and a maximum of 500g of red meat per week is recommended in line with the recommendations of the World Cancer Research Fund. It promotes a higher fat intake with fewer carbs than the NHS reference intakes. The diet is called Pioppi after the Italian village recognized as the home of the Mediterranean diet. The authors use the lifestyles of residents of the town to explain the principles of a healthier Lifestyle and the book also explains how policy changes are needed to change the obesogenic environment.

In 2017 Malhotra wrote an opinion piece for the British Journal of Sports Medicine which made the claim that saturated fat did "not clog the arteries" and that heart disease can be cured with a daily walk and "eating real food". The British Heart Foundation criticised these "misleading and wrong" claims and several researchers took issue with the methodology of the report on which Malhotra based his claims. Prof Louis Levy, the head of nutrition science at Public Health England says "There is good evidence that a high intake of saturated fat increases your risk of heart disease".

Malhotra denounces what he calls the government's "obsession" with levels of total cholesterol, which, he says, has led to the overmedication of millions of people with statins, and has diverted attention from the "more egregious" risk factor of atherogenic dyslipidaemia. He has questioned the worth of statins, saying they may not be of benefit to anybody. With Robert H. Lustig and Maryanne Demasi, Malhotra authored a 2017 article in The Pharmaceutical Journal which disputes the Lipid hypothesis, the link between blood cholesterol levels and occurrence of heart disease. The article was criticized by two medical experts, for being based on cherry-picked science and for creating the impression that most doctors don't believe that diet and exercise are as important as drugs, and that drugs and lifestyle changes are an either/or option. Cardiologist Tim Chico commented that "high cholesterol has been proven beyond all doubt to contribute to coronary artery disease and heart attack ... to say the cholesterol hypothesis is dead is simply incorrect." Rory Collins, an Oxford medical professor, has also sharply criticised pronouncements about statins, and accused Malhotra of endangering lives. Rory Collins has been quoted as saying that scare stories about statins could be as dangerous to public health as Andrew Wakefield's bogus claims about vaccination and autism.

Malhotra has held cardiology posts with the UK National Health Service as a cardiology specialist registrar at Harefield Hospital, at the Royal Free Hospital in Hampstead and as an Honorary Consultant Cardiologist at Frimley Park Hospital. He is a former Consultant Clinical Associate to the Academy of Medical Royal Colleges and is a visiting professor at Bahiana School of Medicine and Public Health, Salvador, Brazil. In 2015 he was appointed as a trustee of the King's Fund and was reappointed for a further three years in 2018.

Aseem Malhotra is a British cardiologist, public health campaigner, author, and advocate of vaccine hesitancy against COVID vaccines. He campaigns for people to reduce sugar in their diet, promotes a low-carb and high-fat diet, and encourages the reduction of medical overprescribing. He was the first science director of Action on Sugar in 2014. He was listed as one of The Sunday Times 500 most influential people in 2016 and was twice recognized as one of the top fifty black and minority ethnic community member pioneers in the UK's National Health Service by the Health Service Journal. Malhotra is co-author of a book called The Pioppi Diet.

In addition to his work as a cardiologist, he has been described as a "highly regarded public health campaigner" and an anti-obesity expert who is "passionate about tackling the companies and policies responsible for creating ... an obesogenic environment". Malhotra explains that his professional work has motivated his public health campaigning:" ..having seen the unspeakable suffering caused by diet-related diseases, I would much rather these patients did not develop them in the first place." In 2013 he was recognized in the inaugural list of the top 50 BME Pioneers in the NHS Health Service Journal, for his research on sugar rich diets and obesity and cardio-vascular disease and for his public health campaigns, including profit-making of big corporations at the expense of public health, unhealthy hospital meals and sale of junk food in hospitals The judges commented that "Yes. He challenges people". In 2014 he was recognized for a second year running in the Health Services Journal top 50 BME Pioneers: described by the judges as "An upcoming star", the entry recognized that he had ignited a debate about over-investigation, over-diagnosis and overmedication and brought media attention to the BMJ's "Too much medicine" campaign.

At the end of 2013, Malhotra won the accolade of being named a "Food Hero" for the Children's Food Campaign for his campaigning against junk food being marketed to children and sugar filled vending machines in hospitals. When Action on Sugar was founded in 2014, he was its first Science Director. Later in that year, his campaigning on sugar led to his being featured in the Evening Standard as being one of ten of London's brightest stars working in science and technology. In 2018 the Guardian's health correspondent, Sarah Boseley, labelled Malhotra as a "dissident scientist", "statin critic" and "cholesterol sceptic". In 2021, Malhotra was appointed chair of the charity The Public Health Collaboration.

His campaigns on these topics have brought him recognition and accolades including as a children's food hero in 2013, one of the top 50 BME pioneers in the NHS in 2013, one of London's brightest stars working in Science and Technology in 2014, and one of the top 500 most influential people in the UK in 2016.

Malhotra campaigns about reducing the consumption of sugar and junk foods, particularly in the diet of children. The fact that most people in Britain, including children, eat too much sugar and that this contributes to obesity is acknowledged by the NHS healthy eating guidelines. However, Malhotra argues that it is unrealistic to expect individuals to avoid cheap, unhealthy, heavily marketed foods and that changes to regulation are needed. He draws analogies to the regulations on tobacco that were necessary to reduce smoking. He also thinks that vending machines in hospitals selling sweets and junk foods send the wrong message. At the time of the London Olympics in 2012, he criticized the choice of sponsors: writing that "In the context of an obesity epidemic I find it obscene that the Olympics chooses to associate itself with fast food, sugary drinks, chocolate and alcohol."

Malhotra studied medicine at the University of Edinburgh and graduated in 2001. He spent his foundation years as a doctor in Scotland, at Wishaw General Hospital then at the Royal Infirmary of Edinburgh and finally at Liberton Hospital which specialises in care of the elderly. He completed his post-graduate medical diploma during two years working at the Manchester Royal Infirmary. He held specialist registrar positions at St James's University Hospital in Leeds and Blackpool Victoria Hospital.

Malhotra was born in New Delhi in India in October 1977. He was the younger son of two doctors: Kailash Chand and Anisha Malhotra. The family moved to Britain in 1978 when his father had a clinical attachment at Alder Hey Hospital and was studying for a Diploma in Tropical Medicine at Liverpool University. Both parents became General Practitioners in Ashton-under-Lyme, Greater Manchester. In 1988 Malhotra's brother Amit, who was two years older than Malhotra and had been born with Down's syndrome, died of heart failure aged thirteen. This inspired Malhotra with the ambition to become a cardiologist. Malhotra was educated at Manchester Grammar School. Malhotra's father went on to become the first Asian to be elected as honorary vice-president and deputy chair of the council of the British Medical Association and received an O.B.E for long-standing service to the NHS. Malhotra's mother's religious faith was important to her and Malhotra observed that she fasted weekly by only consuming one meal on a fast day. He was quoted later as claiming his mother's vegetarian diet contributed to her 'premature and painful death' and said he hoped "we can learn that much of these ills are preventable."
