The Hacker's Diet

There's no better description of this book by Autodesk founder John Walker, than his own: The Hacker's Diet ... is a serious book about how to lose weight and permanently maintain whatever weight you desire. It treats dieting and weight control from an engineering and management standpoint, and provides the tools and an understanding of why they work and how to use them that permit the reader to gain control of their own weight. The book is intended primarily for busy, successful engineers, programmers, and managers who have struggled unsuccessfully in the past to lose weight and avoid re-gaining it.

This electronic 250-page book has gone through many revisions over the past decade and is available online for free in four formats, from frame-based web to PDF files. It's been recommended by many readers.
