The Obesity Code by Dr. Jason Fung

FROM NEW YORK TIMES BESTSELLING AUTHOR DR. JASON FUNG: The landmark book that is helping thousands of people lose weight for good.
Harness the power of intermittent fasting for lasting weight loss.
Understand the science of weight gain and insulin resistance.
Stop suffering and ditch calorie counting, yoyo diets, and excessive exercise.
In this highly readable book, Dr. Jason Fung, long considered the founder of intermittent fasting, sets out an original theory of obesity and weight gain. He reveals that everything you've been told about how to lose weight is wrong: weight gain is driven by hormones, and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss.
Dr. Fung shares five basic steps to controlling your insulin for better health. And he explains how to use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight-permanently.
