True!
Unless a man exercises regularly, he loses muscle mass to fat as he ages, and his testosterone is being converted to estrogen. This occurs because of an enzyme called aromatase. The more fat there is, the more aromatase is produced, which in turn converts more testosterone to estrogen. This can become a viscious cycle.
What can be done about this? Testosterone is critical for maintaining muscle mass. Another important hormone is DHEA(Dehydroepiandrosterone). DHEA levels begin to decline after age 30. DHEA is a hormone that can make testosterone and estrogen. By inscreasing DHEA levels, more testosterone can be produced by the body.
DHEA can be taken orally, and is an over-the-counter supplement. Adequate intake of Zinc can help also. Zinc inhibits the enzyme aromatase. Exercise is critical too. Fat needs to be converted to muscle. We all must maintain adequate muscle mass throughout our lifetime in order to remain healthy and vibrant.
