Summary & Study Guide – The Obesity Code 
Unlocking the Secrets of Weight Loss

Everything you believe about how to lose weight is wrong.

This book is a summary of “The Obesity Code: Unlocking the Secrets of Weight Loss” by Jason Fung, MD.

Most “Eat Less, Move More” programs fail to achieve long-term weight loss because “calorie in versus calorie out” is not the only factor that causes obesity. Obesity is a multifactorial disease. We need a coherent theory to understand how all its factors fit together.

This book provides one such coherent framework that can account for most of what we know about the real causes of obesity. It lays out the root cause of obesity and diabetes is hyperinsulinemia and insulin resistance, and the cure is reducing overall endogenous insulin production/secretion through manipulation of:

• When to eat—practice intermittent fasting


• What to eat—whole foods rather than processed foods


• Avoid insulin spiking foods—sugars/processed carbohydrates/even protein

If you want to reverse type 2 diabetes and treat obesity, read and apply what you learn from this book.
