In this article I will be discussing the main reasons why men develop man boobs.

Before you decide on a course of treatment it would be wise to learn all about the condition, why men get man boobs, the different types of Gynecomastia and how to get rid of man boobs quickly and easily.


I am not a doctor and nor are you. Yes, you do have a problem but there could be other underlying conditions that are causing it. A physical examination by your doctor is the only sure way of knowing exactly what you are dealing with.

You may not like what the doctor has to say with regard to lifestyle changes, but, they are there to help and guide you, not to judge you. Once your doctor has ruled out hormonal problems or medical conditions as the cause, the next step is to learn about the condition and its causes. This will give you a clear understanding of what options are available to you.

What are the different causes of Gynecomastia, male breasts, man boobs or moobs?

  • Lifestyle
  • Aging
  • Drug side effects
  • Puberty
  • Drug abuse

Let’s look at these possible causes one by one.

Lifestyle Changes to lose man boobs quickly:

Overweight or obese men can suffer from Gynecomastia: Many men suffer from manboobs due to their lifestyle. Being overweight or obese is one of the main causes of a fat buildup in the male chest, when the chest retains fat cells, the skin covering the breast area can sag down, giving the appearance of female breasts.

Excessive fat also increases the production of Estrogen, a female hormone that increases the growth of breast tissues.


Excessive intake of alcohol can also cause the problem. Excessive alcohol consumption can change your hormone levels and increase Estrogen production within the male body.

Diet – A healthy diet can help to reduce man boobs.

A poor diet is another major cause of man boobs. Avoiding foods that have high contents of saturated fats and highly processed foods can help to decrease weight and invariably breast tissue.

Certain foods can also be the source of hormonal imbalances. This could possibly result in you developing enlarged male breasts regardless of whether you’re not over-weight or obese. One such food that has a high level of the female hormone Estrogen is soy. Introducing more fruit, vegetables and foods that are low in protein into your daily diet can also help.

Physical fitness – Exercise for man boobs is one of the most effective ways to reduce them:

Increasing your physical fitness will not only help you body to process fat faster it will also have an immense impact on your total well-being. You don’t even have to join a gym or keep fit class to get your body into shape, walking, running and aerobics can all be done in the comfort of your own home.Equipment like treadmills, rowing machines, weights and elliptical trainers can also increase fitness and decrease fat.


As men grow older, they tend to generate a lower amount of the male growth hormone testosterone and some older men have increased fat levels, resulting in a hormonal imbalance within the body that leads to excess breast tissue.

Drug side effects can cause Gynecomastia:

Many prescription and over the counter medications have side effects that can lead to the growth of man boobs. If you are taking any kind of medication, it is best to visit your doctor to find out if the drugs are actually causing the problem.

Puberty and Gynecomastia

When boys enter puberty their hormone levels are very erratic. The testosterone levels may decrease and the estrogen increases, causing male breast tissue to grow. Almost all teen boys that are going through puberty will have some amount of breast enlargement.

Gynecomastia at puberty often goes away as young men mature and their hormones balance out and become more stable. However, for a few unfortunate young men, the breasts will continue to grow after puberty. The problem may resolve itself over time, but a visit to the doctor is advisable to determine if it is hormonal and what can be done about it.

Drug abuse and man boobs

Anabolic steroids are often misused by bodybuilders and athletes due to their muscle building and performance enhancing properties. These types of drugs mimic the male hormones within the human body, however, they could alter the balance of the male and female hormones within the body, causing Gynecomastia.

Illegal drugs such as Amphetamines, Heroin and Marijuana have also been linked to Gynecomastia, but there is insufficient conclusive evidence to support the theory.
