Bodyfat loss linked to testosterone increase

Bodyfat loss linked to testosterone increase By: Dr. Barry Sears Filed: 7/20/98 There is a growing interest in andropause, the male equivalent of menopause, which occurs when testosterone levels decline with aging. With this decrease comes increased risk of heart disease, loss of strength and loss of sexual desire. Now what male wouldn't want to increase his testosterone levels to become stronger, have more sexual desire and live longer? It's a male dream come true. Unfortunately, testosterone is still considered a controlled substance, much like cocaine and heroin. It's not orally active and must be either injected through implants of testosterone or be surgically implanted. However, a recent letter to Science magazine indicates that a radical new method can increase your testosterone levels. What is this new breakthrough? It's called losing body fat. In this study, members of the Air Force who were exposed to Agent Orange in Vietnam had their testosterone levels continually monitored for a 10-year period after they had left the service. Most of these individuals were already in pretty good shape at the beginning of the study. For those men who maintained their body weight, there was no loss of testosterone levels over a 10-year period. Those who gained more than 10 pounds showed a dramatic decline in their testosterone levels. Those who lost weight saw their testosterone levels climb during this same 10-year period. Simply losing weight was the best way to increase testosterone levels. Why this happens is because testosterone can be converted into estrogen by the enzyme known as aromatase, which is located primarily in the fat cells. The more fat cells you have and the bigger they are, the more aromatase you have, and the more testosterone is converted into estrogen. And the best way to reduce the size of the fat cells? Follow the Zone Diet.
