Book Reviews of The Anti-Aging ZoneBook Review: The book of chains Summary: 5 Stars
Here is the extremely simple advice on page 55: reduce your calorie intake and live longer. It is really simple, but that doesn't really help. A low calorie diet translates into the hated: no bread, no pizza, no cookies, no pies.
In hopes of making low calories interesting, Sears offers lots of ways to understand how your cell chemistry works. Maybe it will help you pick the right balance of diverse foods which can make a low calorie diet interesting. If you take this book seriously, you will learn a lot of biochemical cycles. For some reason, I find this stuff fascinating.
The causes of aging:
a) Excess insulin causes one to increase calorie consumption. Excess calories result in excess free radicals and premature cell deaths.
b) Excess insulin causes DNA damage and faster cell replication. Faster cell replication will produce more mutations, and associated dangers.
c) Excess glucose causes AGE (Advanced Glycosylated endproducts) and neural death in VMN (ventromedial nucleus). Together, these damage the hypothalmus, which eventually raises insulin levels.
d) Excess cortisol causes neural death in the hippocampus. Hippocampus failure causes chaos in the hormone system.
Protein plus glucose produce 'schiff base'. 'Shiff base' produces 'Amadori Adduct' which in turn produces AGE (advanced glycosylated endproducts. As mentioned above, AGE is a precursor to neural death in the VMN (ventromedial nucleus).
The Aerobic cycle, fundamental to life, converts glucose and oxygen into ATP (energy), carbon dioxide and free radicals. Free radicals cause early cell death,
Calorie consumption produces:
1. incrase cell turnover
2. inhibits production of eicosinoids (eicosinoids maintain cell-cell communication cells. Following eicosinoids around is the main focus of the book).
3. inhibits glucagon which would increase glucose levels -> increased cortisol production -> higher cortisol levels (faster aging)
4. increases insulin resistance -> incrased insulin level -> more stored fat -> increased plugging of cardiovascular system and reduced sex drive.
ATP + adenylate cyclase -> cAMP (secondary messenger for insulin) (insulin decreases levels of cAMP)
Environmental dangers -> CRH in hypothalums -> stimulates production of ACTH (adrenocorticotropic hormone) in the pituitary gland -> which produces chloresterol ester which reacts with cAMP to produce cholesterol -> prognenolene -> cortisol which decrease eicosanoids and CRH. Increase in cortisol is bad. Exercise and meditation reduce cortisol. Inhibition of glycagon increases cortisol levels.
Summary of The Anti-Aging ZoneHow old are you now? Want to look younger, live longer, and feel better? Enter the Anti-Aging Zone With his #1 New York Times bestseller The Zone, Dr. Sears began revolutionizing nutritional thinking in America. Now, his cutting-edge hormonal-control research is elevated to a new level that promises to change forever how we look at aging. No one wants to get old or show the signs of age. In fact, for centuries many have searched for, and often promised, the fountain of youth. So what makes The Anti-Aging Zone different? In this new, breakthrough book. Dr. Sears goes beyond looking at food as simply a source of calories and explains the incredibly powerful biological effects it has on your hormones. From this unique perspective, food is more than a source of sustenance; it becomes the most powerful drug known to man. More important, it is the only drug proven to reverse the aging process. In addition to unraveling the mysteries of your hormones and their role in aging, Dr. Sears reveals the essential dietary information you need to start your own age-reversal journey. Using his simple and easy-to-follow program, you will be able to live longer and live better beginning with your very next meal. As Dr. Sears explains, the aging process isn't caused as much by the depletion or lack of hormones as we get older, but rather by their impaired ability to communicate with each other. Little-known "super-hormones" called eicosanoids can reestablish the critical communications links between your hormones, which is the key to age reversal. The brilliance of this anti-aging approach is that these exceptionally powerful super-hormones can be altered by the foods you eat, and, in particular, by the Zone Diet. Your body is a vast, complex biological Internet whose hormonal communication can be orchestrated with great precision by the Zone Diet. Hormones from melatonin to serotonin, from estrogen to testosterone, from cortisol to DHEA, can all be controlled if you are willing to treat food with the same respect as you would any prescription drug. Ultimately, hormonal miscommunication is the underlying cause of many conditions associated with "getting older" such as insomnia, wrinkles, dry and dull skin, waning sex drive, depression, chronic pain, obesity, diabetes, heart disease, and cancer. Using The Anti-Aging Zone as your guide, you can look and feel better that you ever imagined. Millions of people like you are now facing the hard realities involved with getting older. Dr. Sears separates the hormonal hype from reality and gives you the necessary tools to add years to your life and improve your appearance. The Anti-Aging Zone is your passport to a longer and better life. Enter the Anti-Aging Zone...you have the power to reverse aging beginning with your next meal. Ask yourself these life-changing questions: Why am I aging? Is it too late to reverse aging? What type of diet will increase my sexual energy and desire? What is my biological Internet? How do my hormones control aging? Can I make my hormones communicate more effectively? Do high-carbohydrate diets accelerate aging? How does stress reduce brain longevity? What are passing grades on my Anti-Aging Report Card? Begin you Anti-Aging lifestyle today! The Anti-Aging Zone includes: A week of Anti-Aging Zone meals for males and females Anti-Aging Zone meals for the business traveler Anti-Aging Zone meals in fast-food restaurants A simple, at-home Anti-Aging Zone exercise program. 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.
