Publisher Description

Everything you believe about how to lose weight is wrong. Weight gain and obesity are driven by hormones—in everyone—and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss.

In this highly readable and provocative book, Dr. Jason Fung sets out an original, robust theory of obesity that provides startling insights into proper nutrition. In addition to his five basic steps, a set of lifelong habits that will improve your health and control your insulin levels, Dr. Fung explains how to use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight—for good.

The Obesity Code

This book was recommended by my doctor. I was having trouble keeping my weight down even though I logged all the food I ate and led an active lifestyle. According to the calorie intake and calorie out principle, I should have been thin like a pin. But I was gaining weight. After reading the book, I started fasting (16 hours fasting and a window of 8 hours to eat). After 3 months, I’ve lost 14 pounds and find it very easy to do

The Obesity Code

A life changing book. Thank you to Dr. Fung for being brave enough to push aside decades of misconceptions and let the evidence speak for itself. It is astonishing that obesity is a hormonal problem and not a caloric one. This approach is achievable and I’m excited to get started and be free from what has been weighing me down for most of my life.
