Getty Images A buzzy British eating plan called the Fast Diet grabbed our attention when it jumped the pond to the United States this spring. The dietwhich involves cutting your calories two days a weekwas created by Dr. Michael Mosley, MBBS, a science journalist, and built on research suggesting that intermittent fasting (IF) can not only help people shed weight but also reduce their risk of heart disease and diabetes. While the concept of fasting for health benefits and weight control has been around for centuries (even Hippocrates recommended it!), it has been gaining momentum in recent months thanks to Dr. Mosley's book The FastDiet (as well as other expert-penned IF offerings, including The 2-Day Diet). Curious? Here is an exclusive excerpt of the bookalong with our own version of a 500-calorie day.
