Biomarkers: The 10 Keys to Prolonging Vitality

The authors have identified ten "biomarkers," the key physiological factors associated with prolonged youth and vitality:

* lean body (muscle) mass

* strength

* basal metabolic rate

* body fat percentage

* aerobic capacity

* blood pressure

* Insulin sensitivity

* cholesterol/HDL ratio

* bone density

* body temperature regulation

With only 50 minutes a day of aerobic exercise and strength training (a pivotal component of the 16-week Bioaction Plan), even middle-aged "couch potatoes" and older adults can:

* regain muscle loss and increase strength by as much as 200 percent

* reenergize the body and actually lose body fat

* increase aerobic capacity by up to 20 percent

* reduce the chances of developing age-related conditions such as heart disease, Type II diabetes, and osteoporosis

Providing dietary guidelines, self-tests for evaluating your physiological age, and exercise programs for every level of fitness, Biomarkers will change forever the way you think -- and what you do -- about aging.
