In this book, Dr. Tim Fischell describes a comprehensive lifestyle program—a time-efficient and sustainable way of exercising, eating and living that helps you lose weight, keep it off, and enhances your health rather than harming it.

Tim and I completed our internship and residency together in internal medicine many years ago at the Massachusetts General Hospital and Harvard Medical School. When you spend three years together with someone in such extreme circumstances, you see clearly who they are and what they’re really like.

I was always impressed with Tim’s intelligence, creativity, and fearlessness, as well as his kindness.
