The diet industry sells simple stories; the science of weight is more interesting and more useful. These seven books explain what actually governs appetite, metabolism and body weight, from how the brain regulates hunger to why exercise does not burn calories the way you think. Written by neuroscientists, anthropologists and physicians, they will make you far smarter than any fad diet, though as always, talk to your doctor about your own situation.

We hold to a simple rule: if we cannot verify an author's credential (MD, PhD, RD, DPT, PsyD, or licensed clinician) from a publisher or university bio in about two minutes, the book does not make the list, with clearly labeled exceptions for a few excellent journalist-authored titles. No cure-all claims, no anti-science, no wellness influencers. We describe and compare these books to help you choose; we do not reproduce their contents.
Please note: these are books, not medical advice. Everyone's health is different. For your specific situation, talk to your doctor before acting on anything you read.
