From the author of the multi-million-copy bestseller The Obesity Codecomes The Hunger Code.

For generations, we've accepted the story that weight loss never lasts -- that as soon as you go off your diet or stop taking your medication you will revert to your old self and regain weight, and the dieting journey will start all over again.

But what if the secret to long-term health isn't just about what we eat -- or even when we eat -- but why we eat? With the rise of ultra-processed foods and new drugs such as Ozempic and Wegovy, understanding the forces behind why we eat is more important than ever before.

In The Hunger Code, New York Timesbestselling author Dr Jason Fung reveals the powerful forces that drive us to eat, and 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 groundbreaking Golden Rules and 45 actionable tips, The Hunger Codeempowers you to recognise and respond to hunger appropriately. You will learn earn how to slow digestion, break emotional eating cycles, and overcome social pressures -- and maintain a healthy weight, whether from scratch, after fasting, or after using diet drugs.
