Staying on a diet long enough to achieve major weight loss can feel like a journey down a deserted highway: there are no signs to tell you where you are, no radio programs to ease the boredom, no restaurants to break the tedium and no one to whom you can complain.

A professor who mentored me when I was a new scientist lost about 120 pounds over the two years I worked with him. After he had lost almost 100 pounds, he confided to me that losing the weight was the hardest thing he had ever done: “I got over the hunger and cravings for foods that I couldn’t eat pretty quickly, but after a few months the excitement from losing the first twenty pounds or so had worn off and I felt alone, in the middle of a weight loss tunnel with no end in sight. No one was particularly interested in my weight loss anymore, and very few people continued to offer encouragement.”
