Exciting new evidence from the USDA Human Nutrition Research Center on Aging at Tufts University has demonstrated that the body's decline is due <I>not</I> to the passing of years but to the combined effects of inactivity, poor nutrition, and illness -- much of which can be controlled. This breakthrough study shows that regardless of your age or present physical condition, the aging process can be slowed -- or even reversed! <P> The authors have identified ten "biomarkers," the key physiological factors associated with prolonged youth and vitality: <P> <B>* lean body (muscle) mass<P> * strength<P> * basal metabolic rate<P> * body fat percentage<P> * aerobic capacity<P> * blood pressure<P> * Insulin sensitivity<P> * cholesterol/HDL ratio<P> * bone density<P> * body temperature regulation</B> <P> 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: <P> * regain muscle loss and increase strength by as much as 200 percent<P> * reenergize the body and actually lose body fat<P> * increase aerobic capacity by up to 20 percent<P> * reduce the chances of developing age-related conditions such as heart disease, Type II diabetes, and osteoporosis <P> Providing dietary guidelines, self-tests for evaluating your physiological age, and exercise programs for every level of fitness, <I>Biomarkers</I> will change forever the way you think -- and what you do -- about aging.
