What is Gynecomastia (enlarged male breasts)?

Gynecomastia is a condition that causes excess tissue to grow in the male chest area (pectoral muscles). This can be an embarrassing and uncomfortable issue for men, impacting their self-esteem and confidence. Although gynecomastia is a physical condition, enlarged breast tissue in men also has a powerful emotional impact.

What Causes Gynecomastia/Man Boobs?

Gynecomastia (or man boobs) have various potential causes, including hormonal imbalance where testosterone levels are low and estrogen levels are too high. Gynecomastia may also be hereditary or caused by insulin resistance or certain prescription medications. Bodybuilders often find anabolic steroids such as Trenbolone and Dianabol can cause bodybuilder gynecomastia.

A healthy diet may help with male breast reduction by naturally optimizing hormone levels and reducing fat. Avoiding certain foods and adding foods that can help reduce excess estrogen levels may also help improve the appearance of the male chest, making it easier to build defined pectoral muscles. A low-fat, balanced diet rich in essential nutrients that support muscle growth will help limit excess fat and male breast tissue. You should avoid estrogen rich foods or pre-estrogen compounds and those that may suppress testosterone production.

Foods That Cause Gynecomastia

Certain foods may cause man boobs with consumption over time. One food group to avoid is soy products such as soybeans and soy milk. All soy products are rich in phytoestrogens (or estrogen like compounds) and may repress the production of testosterone, leading to gynecomastia. Four other food groups to avoid which can mimic human estrogens include:

  1. Flax seed – the richest food source of phytoestrogens.
  2. Nuts such as almonds, pistachios, and peanuts are high in phytoestrogen.
  3. Dried fruit such as raisins and apricots are estrogenic food.
  4. Eggs and dairy products, such as eggs, cheese, and milk from animals

Which Foods Can Prevent Male Breasts?

Maintaining a balance between estrogen and testosterone may aid in the reduction of gynecomastia. There are specific foods that may encourage testosterone production and reduce the risk of gynecomastia.

Five Foods That May Prevent Man Boobs

Following an anti estrogen diet may help reduce gynecomastia and estrogen levels. Add these foods to your diet to reduce excess estrogen levels:

  1. Oysters contain high amounts of zinc, which prevents hypogonadism (reduced testosterone production)
  2. Leafy greens such as spinach and kale contain high levels of magnesium linked to increased testosterone levels.
  3. Ginger has been shown to increase testosterone and increase sperm count.
  4. Extra-virgin olive oil has been shown to increase luteinizing hormone, stimulating the testes to produce testosterone.
  5. Avocados contain magnesium and a trace mineral called boron that has been shown to boost testosterone.

Can Estrogen Blockers and Nutritional Supplements Reduce Gynecomastia?

Human estrogen blockers are often thought to reduce or prevent gynecomastia. However, this is a myth as it is not just the production of estrogen that causes gynecomastia to occur. Many websites will also try to sell nutritional supplements as a solution to excess male breast tissue growth, but they are likely to have little to no effect on gynecomastia.

Lumps in your chest are typically a result of glandular breast tissue that will not go away with diet or exercise. To get rid of gynecomastia caused by excess breast tissue, gynecomastia surgery is usually the only option.

What Is Pseudo-Gynecomastia?

Pseudo-gynecomastia results from gynecomastia (also called man boobs or moobs) caused by fat rather than excess breast tissue. If you are overweight or over your recommended BMI, losing weight and lowering your fat percentage can significantly impact gynecomastia or man boobs. Weight loss can also aid your body to re-balance hormones and make muscles and pectorals more defined.

What Can Help With Weight Loss?

The best diet is different for each person. Dr. Delgado can help you determine the best approach to weight loss based on factors like your lifestyle and habits.

You should also start by adding these healthy foods and essential nutrients to your diet, as well as avoiding processed foods and deep fried foods:

  • Zinc: Lifting weights to define and build muscle and cardio exercise both lower zinc levels. Adding zinc to your diet will help boost testosterone levels – although you can take zinc supplements, you can also eat foods high in zinc such as lean beef, oysters, and shellfish.
  • Vitamin D: This multifunctional vitamin may help to both increase sperm count and testosterone levels. Research has shown an increase in testosterone levels after consuming vitamin D. You can take vitamin D or fish oil, or simply eat vitamin D-rich foods such as oily fish, red meat, and mushrooms.
  • Monounsaturated fats and polyunsaturated fats (healthy fats): Fatty foods rich in healthy fat have numerous benefits and can help reduce the risk of heart disease and boost testosterone production. Good fats can be found in avocados, fatty fish, and olive oil.

    It can also help to limit beer consumption and packaged foods, as well as incorporate more fiber like cruciferous vegetables or sweet potatoes.
