Fact-Checking:

Liana Werner-Gray is an Australian-born author, wellness influencer and natural-health advocate, best known as the founder of The Earth Diet, a nutrition and lifestyle platform established in 2009, and author of several popular diet books.

Werner-Gray describes herself as a certified nutritionist and health coach, although her publicly available biographies do not clearly establish the nature or level of her nutrition qualifications. She is not a medical doctor, and her published work primarily focuses on natural health, dietary advice and personal experiences rather than original scientific research.

Her approach emphasises whole foods, avoiding processed ingredients and using dietary and lifestyle interventions to support health. She has publicly attributed her recovery from a tumour and other health conditions to dietary changes, although these personal accounts do not establish that nutrition was responsible for her recovery.

Through her books, website and social media platforms, Werner-Gray promotes nutritional approaches to managing conditions including cancer, anxiety and chronic disease. She also markets health-related products and educational programmes. Some of her health claims extend beyond what can be established from current scientific evidence, particularly where dietary interventions are presented as treatments for serious medical conditions.
