Men, Estrogen, Weight Gain, and Man Boobs

author avatar Dr. Eric Berg 03/12/2024

Estrogen, although a female sex hormone, is also essential for male physiology. However, when imbalanced it can cause a range of health issues.

Elevated estrogen levels can have detrimental effects on male reproductive function, potentially leading to conditions like erectile dysfunction and breast enlargement.

Discover natural ways of reducing excess estrogen and learn why you should incorporate cruciferous vegetables and stinging nettle roots into your daily routine.

Connection Between Estrogen and Weight Gain in Men

The human body is a complex system of interrelated functions and processes. One such process involves the production of hormones, including estrogen.

While typically associated with women, men also produce estrogen - albeit in smaller amounts and an imbalance of this hormone can result in various health issues.

The Role of Body Fat in Estrogen Production

In men, one significant source of estrogen is body fat.

Fat cells secrete aromatase, an enzyme that transforms testosterone into estradiol (estrogen). This means that individuals with high body fat naturally have a higher estrogen production rate.

Consequences Of High Estrogen Levels

An excess amount of estrogen can have detrimental effects on male health. For instance, gynecomastia or "man boobs" are often attributed to high levels of circulating estrogens. Other potential side effects include erectile dysfunction and mood swings.

Maintaining a healthy weight balance is crucial for men who want to regulate their hormonal profile effectively.

A nutritious low-carb diet combined with regular exercise not only aids in controlling your weight but also helps maintain optimal hormone regulation within your body.

How Liver Function Affects Estrogen Levels

Your liver is crucial to regulate hormonal levels, especially when it comes to estrogen.

A healthy liver processes hormones efficiently, keeping your body's hormonal environment balanced. But if you have cirrhosis or fatty liver disease, this balance can be disrupted.


Cirrhosis, a liver disease characterized by scarring and poor function, can lead to an overproduction of the aromatase enzyme that converts testosterone into estrogen.

This hormonal imbalance can cause problems like erectile dysfunction, enlarged prostate, and even puffy nipples.

Fatty Liver Disease

Fatty liver disease, caused by unhealthy lifestyle choices like excessive alcohol consumption or obesity, can also impact hormone regulation.

It impairs the conversion process where testosterone is turned into estrogen, leading to higher levels than usual for males. This condition can lead to physical manifestations such as gynecomastia and psychological symptoms, including fluctuating emotions.

Natural Ways To Reduce Excess Estrogen

High estrogen levels can cause serious health issues such as gynecomastia and hormonal imbalance, and it's essential to promote hormonal balance.

Here are natural ways to reduce excess estrogen.

Cruciferous Vegetables

Consuming cruciferous vegetables regularly is helpful since they contain Diindolylmethane (DIM), a compound known for regulating hormonal balance.

Such vegetables include broccoli, cauliflower, cabbage, and Brussels sprouts. Studies have shown that DIM helps the body metabolize estrogen, reducing its overall levels.

Stinging Nettle Root

In addition to dietary changes, certain supplements can help regulate estrogen levels in men.

One such supplement is stinging nettle root, which has been used traditionally for various health benefits, including prostate health.

Research suggests this plant extract inhibits aromatase, thus helping maintain balanced hormone levels.

Avoid Xenoestrogens

Avoiding exposure to environmental estrogens or xenoestrogens found commonly in plastic products, pesticides, etc., can further aid in controlling your body's hormone regulation process.

Scientific studies demonstrate how chronic exposure to these chemicals disrupts endocrine function, eventually leading to conditions like obesity, diabetes, and even cancer due to their ability to mimic natural hormones within our bodies, causing imbalances over time.

Role of Fermented Foods in Balancing Hormones

Fermented foods have been a staple in many cultures for centuries.

They're not only delicious but also packed with health benefits, including their potential to help balance hormones. It's believed that probiotics in fermented foods may be responsible for their positive effects on hormones.

The Power of Probiotics

Probiotics are beneficial bacteria that support gut health - an essential factor in maintaining optimal endocrine function.

The gut microbiome is crucial in regulating hormones, including estrogen levels.

A healthy gut can effectively metabolize and excrete excess estrogen from the body. Conversely, an unhealthy or imbalanced gut may contribute to hormonal imbalance by disrupting this process.

Fermented Foods for Gut Health

Including fermented foods like pickles and sauerkraut into your diet regularly can provide you with ample amounts of probiotics necessary for good gut health.

Other options include kefir, kimchi, miso, and tempeh - all rich sources of these beneficial bacteria.

  • Pickles: These tangy treats are low-calorie snacks that offer high amounts of vitamin K and probiotic bacteria, which aid digestion and hormone regulation.

  • Sauerkraut: Made from fermented cabbage, sauerkraut is loaded with vitamins C & K along with iron and manganese, making it an excellent choice for overall wellness.

  • Kefir: A dairy product similar to yogurt but with a more liquid-like consistency, it provides an abundant supply of calcium plus various B vitamins, besides being an excellent source of probiotics.

  • Miso: This Japanese seasoning made by fermenting soybeans has high protein content while offering a diverse range of microbes that promote better digestive system functionality, thus indirectly supporting balanced hormone production.

Benefits of Serrapeptase and Choline for Liver Health

Your liver is a crucial organ that regulates hormones, including estrogen, and a healthy liver efficiently processes hormones and maintains hormonal balance.

However, conditions like cirrhosis can affect liver functionality, leading to hormone imbalance.

Fortunately, certain supplements such as serrapeptase and choline can help improve liver health.


Serrapeptase is an enzyme that breaks down proteins within scar tissue - a common issue for cirrhosis patients.

By assisting in scar tissue removal, serrapeptase promotes better organ functionality, indirectly supporting healthier hormone regulation processes.


Choline helps reduce fat accumulation within the liver. Excessive fat storage in the liver can lead to fatty liver disease - another condition that negatively impacts your body's ability to regulate hormones properly.

Incorporating these two supplements into your diet could significantly enhance your overall well-being by promoting optimal endocrine function and maintaining hormonal balance.

Tips on Taking Supplements Safely

  • Advice from a medical professional should be sought before beginning any supplementation plan.

  • Purchase supplements from reputable sources to ensure their quality.

  • If you experience side effects after taking any supplement, stop its use immediately and seek medical advice.

  • Avoid exceeding recommended dosages unless instructed otherwise by a healthcare provider.


Excess body fat in men can lead to increased estrogen production and decreased testosterone levels, which are linked to various health issues.

Cruciferous vegetables and stinging nettle roots are natural remedies that can help regulate excess estrogens, and consuming fermented foods and supplements like serrapeptase and choline can benefit liver function and improve overall well-being.
