The Longevity Diet

A nutrition and fasting-mimicking-diet framework from a USC longevity researcher, with recipes and practical structure.

An exploratory secondary analysis of randomized clinical trials found that three fasting-mimicking diet cycles were associated with lower insulin resistance and other prediabetes markers, lower liver fat, changes in an immune-age indicator, and a 2.5-year reduction in a median biological-age measure. The authors describe these findings as initial support for effects on cardiometabolic risk factors and biomarkers, not proof of disease prevention or lifespan extension. The supplied evidence does not establish that the book’s full program prevents cancer, Alzheimer’s disease, cardiovascular disease, or diabetes, or that it regenerates human organs.
