Aseem Malhotra is a celebrity doctor based in the United Kingdom, known for his controversial views on diet. He is best known as a promoter of a fad diet called the Pioppi diet and as one of the founders of Action on Sugar. Maholtra's views on diet and health have been criticised 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 diet, the "Pioppi diet" was named by the British Dietetic Association as one of the "top 5 worst celeb diets to avoid in 2018". During the 2020 COVID-19 pandemic Malhotra made claims that following his diet could quickly help people combat the virus; such claims were not backed by good medical evidence.
