An answer to a former "Zoner" who has regained fat and now finds it harder
than before to achieve a desirable weight and body composition.

The loss of muscle mass is a hidden cost of "zoning" as well as the loss of
metabolic rate.

You have lost some of your metabolic fitness, the very common problem of
modern diets and dieting.  You must restore the insulin sensitivity of your
muscle.  It requires muscle contraction to do this.  Sensitivity lasts only
a day or two after intense exercise, so the answer is frequent,
intermittent exercise, with each short session intended to elevate insulin
sensitivity.

I shall have a long section on metabolic fitness in the book.
