Is T3 Hormone Inhibition the Reason Calorie Restriction Results in Increased Human Lifespan?
• Resveratrol Mimics Calorie Restriction Want to slow the signs of aging and live longer? New Saint Louis University research suggests cutting back on calories could be a promising strategy. Calorie restriction has long been shown to slow the aging process in rats and mice. While scientists do not know how calorie restriction affects the aging process in rodents, one popular hypothesis is that it slows aging by decreasing a thyroid hormone, triiodothyronine (T3), which then slows metabolism and tissue aging. A new study in the June 2008 issue of Rejuvenation Research, found that calorie restriction cutting approximately 300 to 500 calories per day had a similar biological effect in humans and, therefore, may slow the aging process. Over recent years, there has been a huge amount of debate about whether calorie restriction slows the aging process in humans, said Edward Weiss, Ph.D., associate professor of nutrition and dietetics at Saint Louis Universitys Doisy College of Health Science
