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.

    I am a physician and deal day in and day out with patients that battle obesity and diabetes with little improvement despite repeated visits in the office with re-educating them about weight loss methods (decrease calories and exercise more). My default reason for their failure has been to blame the patient for obviously ‘not following directions’. Now I know why they continue to fail. The Obesity Code completely changed my thinking about weight loss. I too have struggled with the ‘calories in less than calories out’ and likewise would eventually fail. Taking Dr. Fung’s advice, I have finally lost the weight and kept it off (and my fatty liver resolved as well!) The medical field needs to completely re-educate itself about the hormonal cause of obesity so we can better treat our patients.
