You know what you need to do to lose weight, so why can't you do it?

Morbidly obese and desperately unhappy, Gregg McBride asked himself this question for years, until something different finally "clicked," and enabled him to embark on a weight-loss journey of 250 pounds that has now lasted ten years and still counting.

Alternately hilarious and heartbreaking in its honesty, Weightless is Gregg's story, but it is much more. It's an exclusive weight-loss plan with menus, recipes, exercises, and motivational techniques. Weightless will move, educate, entertain, and inspire anyone who is ready for change.
