Query: Christianity, the best diet ever.

The original edition of this book was an interesting and inspiring approach to weight management written in a direct and reader-friendly manner. This edition is an uneasy hybrid of religious proselytizing and weight loss advice based on the notion Christianity is the best diet ever. The theory and tips that made Thin Within so useful in its first incarnation are buried under an avalanche of quotes from the Christian Bible, and digging your way through is an exhausting task. The implication that Jews, Muslims, Buddhists, Taoists, Pagans, atheists and everyone other than born-again Christians are excluded from the Hallidays' weight management paradise because they lack the requisite theology is simply offensive.
