Estradiol: The True Enemy
Estradiol is the form of estrogen known as E2. Its role in the human body is as an anti-androgen. Estradiol binds to androgen receptors, thus blocking testosterone from binding. So we can easily call it an enemy.
If you have a high level of estradiol, you have many enemies acting against your testosterone. No matter how much testosterone you have, it won’t help if you have a powerful estradiol army. That’s why men sometimes experience no direct effect after raising their testosterone level.
Your task should be to lower estradiol so your body can restore itself, but this takes time because estradiol has long-term damaging effects. High levels of estradiol over time cause the body to produce fewer androgen receptors during cell regeneration. And estradiol doesn’t end its war there! It also binds to and activates estrogen receptors. Testosterone converts to estrogen, so you must control your estrogen even while working to raise testosterone.
This is especially true for older guys because our bodies naturally produce more aromatase, a key player in turning androgens into estrogens, which is also responsible for the production of estradiol.
The problem for old men is the decline of testosterone. Estradiol remains constant, so theresulting change in the ratio of testosterone to estradiol causes excess active estrogen.
Balancing Estradiol Levels
Reduce body fat.
Fat produces estrogen, so more body fat means more estrogen factories. Losing fat shuts down those factories.
Eat a low-carb diet.
In order to manage estradiol you have to manage your insulin, and the best way to do that is with alow-carb diet. A good diet is essential to controlling your estrogen level. Look at the graph above again to see why a high-carb diet is harmful. Low insulin levels not only control estrogen, but also produce more HUMAN GROWTH HORMONE (HGH) in your body.
By avoiding carbs your diet will be rich in proteins and fats, which is another good way ...
