Diet and exercise can definitely lend them self to a better sense of well being and all over improvement but it can't turn an aging man into a 20 year old again... genetic aging won't allow it. This is where HRT comes into play... anti-aging medicine.

Also to note, being overweight will increase the level of estrogen in your body. Elevated levels of estrogen influence the negative feedback loop that lowers testosterone.

It works like this:

Your body has an equilibrium of testosterone (androgens) and estrogens that is determined by your metabolism, genetics, age, etc. This is all controlled by your hypothalamus.

1. A small percentage of testosterone you produce is converted to estrogen by an enzyme.

2. Your hypothalamus recognizes this estrogen and uses it as one measurement to control the release of gonadatropins that will signal your balls to produce testosterone.

To your body, too much estrogen means there must be too much testosterone... so it must be lowered to reach that equilibrium once again. Your brain reduces demand for the production of testosterone.

If estrogen is produced by adipocytes (fat cells) and not the aromatizatoin of testosterone,your body will strive to correct this estrogen imbalance by lowering testosterone.

Lose weight and your T should increase slightly... but don't expect a miracle.
