| Amazon.com Barry Sears started the diet movement of the decade with the Zone's 40-30-30 eating plan (40 percent carbohydrate， 30 percent each fat and protein). In The Anti- Aging Zone， Sears explains that he thinks aging is not caused so much by depleted hormone levels but by a lack of communication among hormones. So what exactly do these hormones have to do with aging? Estrogen and testosterone levels affect sex drive and skin tone; a drop in melatonin can lead to insomnia. Wavering serotonin levels have been shown to be a factor in depression. Insulin gone haywire can mean diabetes. While the intricacies of these hormonal interrelationships are the makings of a graduate degree in endocrinology， Sears offers a layperson's short course. It boils down to this: the vastly complicated hormonal action in humans is controlled by eicosanoids， what he calls "super hormones." And eating in the way advocated by The Anti-Aging Zone， he argues， can help maintain proper eicosanoid functioning， thereby preventing the litany of health problems associated with aging--both mental and physical. The Anti-Aging Zone is sure to be controversial: Sears recommends a daily intake of just 1，200 calories for women and 1，500 for men， about 40 percent fewer than the U.S. RDA. It's also not just a diet plan， but a lifestyle plan， with guidelines for meditation (to reduce levels of cortisol， a stress hormone) to improve brain longevity， and moderate amounts of exercise， including strength training. But Sears adds a solid guide to supplements (the essential， the important， the exotic and expensive) and herbs， and a rundown of the mind-body-diet connection. While The Anti-Aging Zone isn't especially easy to follow， it's an eye-opening and educational guide to the aging process and the control you have over your own health. Amazon.com Audiobook Review Americans have been systematically overeating for the past 15 years， author Barry Sears states， and thus cheating themselves out of longer， more functional lives. So passionate is Sears about his central idea--eat less， live longer--that it seems as if he has to deliberately put the brakes on his own voice to keep his theories from tumbling out in one big incomprehensible jumble. (Even with the brakes on， many words--like cal'rie--lose a syllable.) Odd cadences aside， Sears makes the case that his high-protein， low-carbohydrate， moderate-fat Zone diet plan will help people live to a riper old age.
