Throw back that Heineken for Instant Man Boobs

Beer is estrogenic

Have you ever wondered how some men are prone to gaining adipose tissue in their chest? There is a reason for this — it’s called aromatization.

Aromatization is the process in which the hormone testosterone gets converted to estrogen. This is not a good thing for a man. If man boobs weren’t bad enough, high levels of estrogen in men can additionally cause:

  1. Decreased sex drive, sensitivity and performance
  2. Increased risk of prostate cancer with a certain type of excess estrogen [1]
  3. Decreased testosterone and free testosterone [2]
  4. Increased amount of SHBG (sex hormone-binding globulin) – Concomitant with the fall in total testosterone is a rise in SHBG levels [3]

How does a man reverse this process?

  1. Don’t touch the hiney (Heineken) or any beer for that matter. Simply switch to red wine or the hard stuff.
  2. Take supplemental Zinc — Supplemental Zinc helps maintain or raise testosterone levels.
  3. Take supplemental DIM — Supplemental DIM stimulates estrogen metabolism
  4. Eat cruciferous vegetables — Cruciferous vegetables contain DIM
  5. Test your HCL levels (hydrochloric acid levels) and supplement if deficient — Adequate HCL levels break down cruciferous vegetables to absorb DIM

Why is beer estrogenic?

A study in PubMed states that hops have been shown to contain one of the most potent in vitro estrogenic substance known from the plant kingdom, (±)-8-prenylnaringenin. Like soy, men need to stay away from hops as well due to it’s estrogenic effects. Of course, beer in moderation can be fine for many people – just realize that if you have low testosterone, are in a state of aromatization, or have unwanted adipose tissue in the chest region – simply follow the steps above.

If you are reading this locally and wish to visit my personal training facility in Palo Alto, a BioSignautre analysis can be administered to help you in arresting or possibly reversing your aromatization problem.
