Valter Longo’s work focuses on scientific research, education, and public programs promoting healthy longevity and the prevention of age-related diseases. Dr. Longo is the Edna M. Jones Professor of Gerontology and Biological Sciences at the University of Southern California and directs its Longevity Institute, a center for research on aging and related conditions. His website shares guidance on nutrition, exercise, and fasting-mimicking diets for adults, children, pregnancy, and breastfeeding, alongside information for patients and doctors on cancer, neurodegenerative and autoimmune diseases, cardiovascular conditions, diabetes, and obesity.

The brand’s resources include books such as The Longevity Diet, At Longevity’s Table, and Fasting Cancer, as well as family nutrition guidance and recipes. It also offers scientific articles, educational materials, videos, and information about a documentary inspired by Longo’s books. Through the Valter Longo Foundation and Create Cures Foundation, the work supports research, public education, and patient services, with an emphasis on making knowledge and potential care more accessible. Longo states that book royalties and consulting fees are donated to charitable causes.
