Dr. Idrees Mughal (Dr. Idz)

Dr. Idrees Mughal, known online as Dr. Idz, is a practising NHS doctor with a master's degree in nutritional research and board certification in lifestyle medicine. Since January 2021, he has posted evidence-based videos across TikTok, Instagram, and Facebook under the handle @dr_idz, targeting the vast ecosystem of nutritional misinformation that circulates on social media — fad diets, detox products, misleading supplement claims, and unscientific lifestyle advice. His videos are notable for citing primary research rather than opinions and for directly naming specific misinformation rather than speaking in generalities.

Mughal's dual background in clinical medicine and nutritional research gives him unusual standing to evaluate diet and health claims at both the biochemical and the clinical level. He gives educational workshops and lectures to schools, universities, hospitals, and health institutes across the United Kingdom, and has contributed to several peer-reviewed research publications. In 2023 he published Saturated Facts: A Myth-Busting Guide to Diet and Nutrition in a World of Misinformation with Penguin Books, a systematic examination of popular nutritional myths and the evidence that refutes or complicates them.

His work addresses a genuine gap: the nutrition information space on social media is disproportionately dominated by influencers without scientific credentials selling supplements or promoting restrictive eating patterns. By offering a credentialled, evidence-grounded alternative in the same short-video format, Dr. Idz competes for attention in the same spaces where misinformation spreads fastest. His audience has grown substantially since 2021 and spans well beyond the UK.
