"Most of us will never lose weight and keep it off by simply restricting calories. Permanent weight loss requires changing your body's set-point, and your body's set-point is largely determined by hormones.
To shed body fat, we need to clear a hormonal clog in the fat-metabolism system. Clearing the clog is, of course, a matter of choosing the right foods and the right kind of exercise, not just eating less and moving around more." - Tom Naughton, blogger and documentary filmmaker
