Does Losing Weight Make Your Penis Bigger? The Hard Facts

Does losing weight make your penis bigger? While no scientific evidence has been made to prove this, losing weight can make your penis bigger depending on your situation. Losing weight can give your body a more defined silhouette, and some men believe it will make their penis larger.

Realistically, the size of the penis is determined by genetics and can vary significantly among individuals. What’s considered "large" or "small" can also vary depending on culture, personal preferences, and your geographical location.

So will losing weight make your penis bigger? This depends on a lot of factors, which we’ll be discussing below.

Does Losing Weight Make Your Penis Bigger?

Let me preface this by saying that while size does matter, it’s not all that matters. Most women are perfectly satisfied with an average-sized penis. But what really makes the difference is your confidence in the bedroom. Your willingness to try new things and listen to feedback will determine how much fun you and your partner will have in bed–more so than the size of what you’re packing.

But too many internet myths perpetuate that weight loss = a bigger penis size. So does your penis get bigger when you lose weight? Although there isn’t enough scientific documentation between penis size and body fat percentage, the answer to this question is: Yes. Generally speaking, losing weight will make your penis “bigger”. It won’t make your penis grow bigger, but you’ll be able to use more of it without having your stomach get in the way.

Why Losing Weight Makes Your Penis "Bigger"

If you’re obese or fat enough to have your stomach leading your walk, there’s a big chance that the base of your penis is blocked by your stomach. If you’re having sex, this means your stomach will push against your partner before the base of your penis. Essentially meaning using less dick.

Weight loss will not only improve your strength and stamina but will also clear up all the fat surrounding your penis. This gives it the illusion of it being longer because now you can use more of it.

Additionally, if you’re a teenager and your penis is still growing, then losing weight should help make your penis bigger. People with more body fat produce less testosterone than normal, resulting in lesser development of male features. This results in narrower shoulders, less facial hair, and, yes, stunted penis growth.

How obesity can affect your penis function

Obesity, which is defined as having a body mass index (BMI) of 30 or higher, is associated with hormonal imbalances and can affect the production of hormones such as testosterone and estrogen. Testosterone is important for developing male sex organs and secondary sexual characteristics, such as facial and pubic hair, and a deeper voice. Estrogen is a hormone typically present at lower levels in men but is important for maintaining bone density and sexual function.

Obesity generally leads to low testosterone and high estrogen levels in men. This directly affects fertility, sexual function, and overall health, and is the reason why losing weight through a healthy diet and regular exercise can help improve hormonal imbalances.

Unfortunately, when it comes to growing a penis, losing weight to improve penis growth only applies to teenagers and young adults who are still in puberty and whose bodies are growing. If you’re in your 30s, then losing weight won’t make your penis grow any larger than it already is.

What kind of fat is around your penis

The fat affecting your penis size is called subcutaneous fat. This is often referred to as "belly fat" since it can be found around the waist and hips. While you may not have been born with it, subcutaneous fat tends to accumulate over time as our bodies age. This stubborn layer of fat is much harder to get rid of than other types like visceral or abdominal fat.

Thankfully, you can easily get rid of subcutaneous fat through diet and exercise. It doesn’t even need to be an extreme diet or exercise regimen. A bit of cardio that burns off calories and a diet rich in fiber can be enough to lessen belly fat.

Why weight loss does not affect the actual penis size of adults

When we’re referring to the actual penis size of adults, once you’re passed puberty there’s no natural way for your penis to grow. If you’re a 23-year-old man reading this, then that’s what you have to work with. Unfortunately, our penis stops growing after puberty.

Does losing weight make your dick bigger? There is no naturally proven way to increase the size of the penis, and attempting to do so can be dangerous and potentially harmful. Some people try to use supplements, creams, or other products that claim to increase penis size, but there is little to no scientific evidence to support these claims.

Why is There Little Research Regarding Weight Loss and Penis Size?

Contrary to popular belief, there’s not a lot of research about many things in the world, including whether or not losing weight makes your penis bigger. This is because research is expensive, mostly driven by profit and relevance, and extremely specific.

While money and profit can be funded, being extremely specific is difficult. Scientific papers need to have a specific scope, clearly-defined conditions, and very controlled variables to make the research credible and reliable. Unfortunately, the hormones involving weight loss and penis length are too diverse to easily correlate with each other. Not to mention that the methodology of this paper would be too complicated.

For example, researchers would have to find a fat teenager, measure his penis in his early teens, make him lose weight, and then measure his penis again after several years. After that, they have to approach his father, his father’s brothers, and his mother’s brothers, and ask all of them about their penis size. All of this to confirm whether or not the sample, which is the teenager, is performing well for his genetics or not.

Why Does it Seem Like the Penis Gets Bigger When You Lose Weight?

Wondering if losing weight makes his penis bigger

For those of you who have encountered some anecdotal evidence or some guy who claims to have increased his girth and length by losing weight, here’s a quick explanation.

The reason it seems like your penis gets bigger when you lose weight is that the excess fat around your penis is reduced. This highlights your penis, like a tree on flat ground instead of being surrounded by hills.

It’s also a matter of posture. Leaner, thinner men don’t lean forward as much as fatter men who do so because of the excess weight they carry on their stomachs. Straightening the back naturally moves the pelvic area forward instead of curling inward. Having your stomach and pelvis aligned creates a flat surface, which adds emphasis to your nether regions.

Why focusing on overall health should be the goal

Excess body weight may affect more than just your penis’ appearance. Obesity and being overweight can contribute to erectile dysfunction, making it difficult for a person to achieve and maintain an erection. Losing weight and improving overall health can increase erectile function and increase blood flow to the penis.

Losing weight and getting fit can also have several health benefits, including reducing the risk of obesity-related diseases such as diabetes and heart disease, improving sleep, and increasing energy levels. This can lead to a healthy confidence boost, which is a bigger turn on for women than a bigger penis. In fact, you might be surprised to know that most women don’t really think about the size of their partner’s penis and are perfectly content with what they have.

There are many different approaches to losing weight, and it's important to find a method that works for you. This may include eating a balanced diet that is rich in fruits, vegetables, and lean proteins. Getting regular physical activity is also highly recommended.

Losing weight in a healthy and sustainable manner is always better than trying to lose weight quickly using unhealthy methods. Some people find it helpful to work with a healthcare provider or a registered dietitian to develop a weight loss plan tailored to their individual needs and goals. Others may find support from a weight loss group or a program such as Weight Watchers.


Can losing weight make your penis bigger? Yes and no. Weight loss does not directly affect the size of the penis unless you’re still a teenager undergoing puberty. However, excess body fat, particularly in the pubic area, can make the penis appear smaller by burying it under layers of fat.

Losing weight and reducing fat in the pubic area may make the penis more visible and potentially appear larger, but there is no proven way to increase the size of the penis naturally. Attempting to do so can be dangerous and potentially harmful.

Instead, it's important to focus on maintaining a healthy weight and overall health. Build your confidence instead of trying to change the size of your penis.
