About Us

For most of us, losing weight is healthy, but it’s not easy. That’s where The Fasting Method can help. Here’s our story.

In, 2012 after extensive scientific research, Dr. Jason Fung and Megan Ramos established the first intermittent fasting clinic in North America and the results were simply astounding. People were successfully losing weight and reversing their type 2 diabetes.

By 2014, the online coaching program began to help people from all over the world. The Obesity Code was released in 2016, providing the scientific basis for weight loss. The book has sold close to a million copies and is one of the bestselling nutrition books of the last decade. The Complete Guide to Fasting provides more practical guidance with recipes from Megan Ramos. Check out our other best-selling books here.

We continue to help thousands of people in our Community, lecture at scientific conferences and publish original research on the use of intermittent fasting for weight loss and the reversal of type 2 diabetes.
