If you watched the fasting video on my home page and want to explore the subject more deeply, these are six books worth investigating.
I deliberately selected books that approach fasting from different angles. Some are practical guides, while others focus more heavily on metabolism, longevity, neuroscience, circadian biology, history, and the scientific research surrounding fasting.
I don't suggest accepting everything in any single book as established fact. Read broadly, compare claims with the evidence, and reach your own conclusions.
