FROM THE AUTHOR OF THE MULTI-MILLION COPY BESTSELLER THE OBESITY CODE COMES THE HUNGER CODE.

For generations, we've accepted the story that weight loss never lasts—that as soon as we go off the diet or stop taking the medication we will revert back to our “old self,” regain the weight, and the journey will start all over again. Traditional medicine continues to treat the symptom of weight gain rather than addressing its root causes. Too often, healthcare systems intervene with quick fixes and short term solutions, ignoring the factors that lead to sustainable weight loss that can last a lifetime.

What if the secret to long-term health isn’t just about what you eat—or even when you eat—but why you eat?

With the rise of ultra-processed foods and new drugs like Ozempic and Wegovy, understanding the forces behind why we eat is more important than ever before.

In The Hunger Code, New York Times bestselling author Dr. Jason Fung reveals the three powerful forces that drive us to eat:

• Physical Hunger
• Emotional Hunger
• Social Hunger

Dr. Fung also introduces the concept of the body’s“fat thermostat”—a biological “set point” that regulates how much fat your body tries to maintain. Guided by hormones and metabolism, this internal system influences hunger and energy use, explaining why lasting weight loss requires more than just willpower …

With three Golden Rules and 45 actionable tips,The Hunger Codeempowers you to recognize and respond to hunger appropriately. Learn how to slow digestion, break emotional eating cycles, and overcome social pressures, so you can maintain a healthy weight—from scratch, after fasting, or after using diet drugs.
