Key Takeaways

PCOS belly is usually associated with excess stomach fat. But it can also be caused by bloating. In all cases, the root causes are linked to insulin resistance, chronic inflammation, and elevated androgens. Gut health plays a key role in these mechanisms.

You can get rid of a PCOS belly by improving your diet and through the use of supplements. Get started today with this free 3-Day Meal Plan or join my free 30-Day PCOS Diet Challenge.

Other lifestyle improvements like exercise and sleep can also be powerful interventions. It’s essential to be properly screened for thyroid dysfunction.

Bloating and excess belly fat are the most common PCOS symptoms. Even lean women with PCOS often struggle with this symptom.

This article explains what a PCOS belly looks like. You’ll also learn how to get rid of PCOS belly using evidence-based lifestyle interventions.

As a companion to this article, I’ve created a free 3-Day Meal Plan that includes recipes and shopping list.

What Does a PCOS Belly Look Like?

Everyone wants to know what does a PCOS belly look like. In normal-weight women, having excess fat only on your tummy is a textbook sign of PCOS. But the reality is that there’s no stereotypical PCOS belly “look”. A PCOS belly shape can fit any of the examples shown in Figure 2.

PCOS Belly Shape

Figure 2. What’s your PCOS belly shape? All are possible as a result of this syndrome.

Because PCOS belly shape varies widely, this can create confusion. But the variability in PCOS belly shape is a consequence of the many different factors at play. Everything makes more sense when you understand the causes of PCOS belly.


There’s no one way for a PCOS belly to look. It depends on your unique diagnosis. Oftentimes, there’s a combination of factors that need to be parsed.

What is PCOS Belly?

PCOS belly is caused by three things. Bloating, subcutaneous fat, and visceral fat.

Bloating occurs when you have excess gas within your GI tract. This can be caused by irritable bowel syndrome or food sensitivities. Constipation or microbial overgrowths also cause bloating.

Subcutaneous fat is the fat you can see under your skin. It’s the soft stuff that you can pinch (or grab). Visceral fat, by contrast, is fat that sits around your organs.

Both subcutaneous and visceral fat are responsible for abdominal weight gain. But visceral fat is the more dangerous of the two. You can’t see visceral fat but it pushes your abdominal wall outwards. This creates the classic beer-belly look. The abdominal wall is made of muscle and tough fibrous tissue which is why visceral fat makes your abdomen hard.

Having a waist-to-hip ratio that’s more than 0.85 can be a useful diagnostic measure of polycystic ovary syndrome [48]. This is particularly useful for lean and normal-weight women.

For women with PCOS, bloating, subcutaneous fat, and visceral fat can all be an issue.

This creates confusion. But it’s also an opportunity for an easy win.

A lot of women join my free 30-Day PCOS Diet Challenge because they want to lose belly fat. Doing so in a healthy way is a slow and steady process. But bloating can often be addressed quickly. If you’re dealing with bacterial or fungal overgrowth things can take longer. But in most cases, dietary change can ease bloating within weeks, if not, days.

Relieving bloating reduces your waist circumference. Racking up some easy wins like this makes it easier to stick with the dietary changes that help with belly fat over the longer term.


PCOS belly can be caused by bloating, as well as excess abdominal weight gain. Bloating can often be addressed easily. Body composition is best improved over the long term.

Root Causes of PCOS Belly Fat

Women with PCOS have higher central abdominal fat deposits independent of body mass index [1].

This is why normal-weight women get a PCOS tummy too [2-4]. It’s also why the same PCOS diet works for all the different types of PCOS. Lean women tend to have a milder form of PCOS, but all PCOS phenotypes exist on the same spectrum. This means that the solution is the same too.

The root causes of PCOS are well understood. PCOS is driven by poor insulin regulation, elevated androgens, and chronic inflammation [5-10]. Diet is also a key factor in PCOS pathology [11].

Other factors contribute to PCOS belly fat too. Other hormonal imbalances relating to stress and cortisol responsiveness are strongly associated with abdominal obesity [12]. PCOS women may be particularly at risk here as studies show we have a “disturbed stress response” [13].

Thyroid dysfunction is another common underlying cause of PCOS belly fat. Autoimmune thyroiditis affects more than one in four women with PCOS [14, 15]. Many of these cases are undiagnosed.

Understanding these mechanisms points us toward the solutions to PCOS belly fat.


Poor insulin regulation, elevated androgens, and chronic inflammation cause PCOS belly. Diet is the best way to address these issues.

1. Regulate Insulin with Diet

Insulin resistance and body fat are intricately linked [16, 17]. Focusing on lifestyle changes that improve insulin sensitivity can solve both of these issues.

Following a PCOS diet is key. PCOS women with insulin resistance experience elevated insulin levels after consuming carbohydrate-rich foods. This is because one of insulin’s many roles is to transport glucose sugar from the blood into the body’s tissue where it’s either used or stored.

Research has shown that a typical Western diet is not appropriate for women with PCOS [11]. Most people eat too much sugar and carbs. What women with PCOS need instead is to eat fewer carbs sourced from low-GI whole foods. This usually means cutting sugar intake too.

Fats and proteins have minimal impact on blood sugar levels. Consuming healthy fats and protein with carbs slows the rate at which blood sugar levels rise. Dietary fiber also has this effect.

This is why it’s recommended that women with PCOS eat a low-carb, high-fat, adequate protein diet. I explain this further in my article on the best macros for PCOS. If you want to lose PCOS belly fat, then getting your macros right is essential.

For examples of what a macro-balanced PCOS diet looks like, download this free 3-Day Meal Plan. Or sign-up for my next free 30-Day PCOS Diet Challenge.


Altering your diet to better manage your blood sugar levels is the best way to improve insulin regulation. This is key for driving weight loss from the stomach.

2. Regulate Insulin with Supplements

Metformin is the most widely used pharmaceutical for improving insulin regulation in women with PCOS. But experts now warn against its use for this purpose. As I explain in my article on Metformin for PCOS, this drug doesn’t help you lose weight either.

Fortunately, other natural medicines may be better.

Inositol is one of the best supplements for PCOS. This class of vitamin-like compounds has insulin-regulating effects. But like metformin, the impact on PCOS related weight loss is small.

Berberine and Vitamin D are possibly the best PCOS belly supplements. As explained more in my article on Berberine for PCOS, this natural herb doesn’t promote weight loss overall. But it’s effective at reducing visceral fat [18]. It also improves insulin regulation and is well-demonstrated as an effective treatment [19, 20].

As I explain in my article on Vitamin D for PCOS, women with PCOS need to ensure they have adequate levels of this essential nutrient. Given its health-wide impact, insufficient vitamin D is a significant barrier to PCOS weight loss. Supplementation is required for most women.

Magnesium also appears to be important. Studies show that having normal magnesium levels is essential for optimal insulin regulation [21]. A recent review of the literature supported the importance of this mineral for women with PCOS. Magnesium combined with vitamin E or zinc-calcium-vitamin D improves metabolic health [22]. Women with PCOS have increased risks for mineral deficiencies [23]. Given this hazard, nutrient supplementation can be another easy win in your battle with a PCOS belly.

Several dietary supplements can further enhance insulin regulation. Inositol, berberine, vitamin D, and magnesium are among the most important supplements to consider.

3. Regulate Insulin with Lifestyle

Other lifestyle changes also improve insulin sensitivity.

The best exercise for PCOS belly fat is the exercise you do. That’s because both strength training and aerobic activity improve insulin sensitivity in women with PCOS [24-26]. So, find what you enjoy, and make a habit out of it. There’s no need to focus on specific exercises for PCOS belly. Things like planks and crunches etc. These types of exercise will help your muscle tone and strength. But they don’t result in any localized fat loss.

Intermittent fasting has also been demonstrated in PCOS populations. Limiting eating to within eight hours each day can improve body composition and insulin resistance. Menstruation, chronic inflammation, and androgen regulation can also be improved by fasting [27]. Learn more about what the science says on intermittent fasting for PCOS here.

Insufficient sleep is another risk factor for insulin resistance [28-30]. Better rest at night has many other benefits that can help you reduce belly fat. Inadequate sleep makes you less active and impacts your eating habits [31, 32]. For example, getting more sleep reduces sugar cravings [33, 34].


Exercise, intermittent fasting, and better sleep all improve insulin regulation. This can help reduce PCOS belly fat.

4. Lower Androgen Levels

Elevated androgens like testosterone are one of the hallmarks of a PCOS diagnosis. Elevated androgen levels are closely associated with insulin resistance. Some researchers believe these two factors are the main causes of PCOS [5].

This means that anything that lowers androgens can help with losing belly fat with PCOS. This is often the argument used for PCOS teas or anti-androgenic herbs for PCOS. These may help on the margins, but the strength of the effects is usually small.

The best way to lower androgens is to improve insulin sensitivity (see above). Reducing inflammation is also very powerful.


Lowering androgen levels can help relieve PCOS symptoms (including PCOS tummy fat). Anti-androgenic compounds have a small effect. But it’s more important to improve insulin regulation with diet and lifestyle changes.

5. Reduce Inflammation

Chronic inflammation is one of the underlying mechanisms that cause PCOS [6-11]. That’s why reducing inflammation helps with PCOS belly on several fronts.

Inflammation occurs when the body’s immune system is triggered. There are many ways that our everyday environment creates an inflammatory burden. Endocrine disruptors found throughout the household can exacerbate pre-existing PCOS inflammation. Other factors like poor air and water quality, or chronic infections also drive an inflammatory response.

The biggest source of inflammation for women with PCOS though occurs through the gut.

Inflammation occurs whenever intestinal permeability is compromised [35]. There are several common causes of increased gut permeability:

  1. Imbalances in the gut microbiome [36]
  2. Sugary foods [37]
  3. “Vegetable oils” [38]
  4. Gluten-containing foods [39, 40]
  5. Dairy products (for people with dairy intolerances) [41]
  6. Other food allergies or intolerances
  7. Heavily processed foods

The impact of these foods to avoid with PCOS guides the creation of my PCOS recipes. The meal plans I provide during my free 30-Day PCOS Diet Challenge are all gluten and dairy-free. Same with those in my free 3-Day Meal Plan. I don’t use vegetable oils and sugar is kept as low as practical. A healthy gut microbiome is also promoted through the consumption of prebiotic vegetables. The results speak for themselves.


Lowering your inflammatory burden can help reduce you PCOS belly. Minimize environmental exposures and improve gut health by avoiding inflammatory foods.

6. Relieve Stress

Stress and obesity are trapped in a vicious cycle. Obesity causes stress and stress causes obesity [42].

Stress causes abdominal fat accumulation by increasing cortisol secretion [43, 44]. It also alters our behavior making weight gain easier and weight loss harder [45].

Researchers have tried to break this cycle with evidence-based interventions. For example, a mindfulness program for stress eating showed some promise. Improvements in mindfulness, stress, and cortisol were associated with reductions in abdominal fat [46].

But there are many other practical ways to help relieve stress. Slow down, cut yourself some slack, and connect with the people you love. Getting more sleep and making time for exercise can also help.

Many women want to know if coffee is bad for PCOS. Your sensitivity to stress plays a large role in answering this question. From what I’ve seen in the laboratory of real life, among other things, quitting caffeine helps get rid of PCOS stomach fat.


Stress and excess stomach fat are intricately linked. Any step that reduces psychological stress can help reduce PCOS stomach fat.

7. Get Your Thyroid Sorted

Thyroid dysfunction is a common comorbidity of PCOS [14]. It’s also closely associated with obesity [47].

Because PCOS and thyroid dysfunction share so many similarities, a PCOS diet also helps with an underactive thyroid. But sometimes diet alone isn’t enough.

Depending on your circumstances, you may need medical assistance. This can further enhance your efforts to get rid of excess PCOS lower belly fat. To understand your unique requirements, it’s important to get a full thyroid panel. You don’t want to rely on the standard tests for TSH and T4. These thyroid biomarkers can be normal in women with PCOS despite an underlying thyroid disorder. A proper diagnosis can only be made with a thyroid panel that includes TBG, T3, reverse T3, and thyroid antibodies (TPOAb and TGAb).

Speak with your doctor about getting these tests.


It’s common for thyroid dysfunction to go undiagnosed in PCOS patients. This can make it particularly difficult to get rid of excess stomach fat. Insist your physician orders a full thyroid panel.

The Bottom Line

Bloating and excess stomach fat are common issues within the PCOS community. Bloating can often be resolved quickly. But a slow and steady approach is best for losing belly fat with PCOS.

Many interventions target the underlying causes of PCOS belly. Dietary change is the most important place to start. For help putting a PCOS diet into practice, sign-up now for my free 30-Day PCOS Diet Challenge. Or begin today with this free 3-Day Meal Plan.

Other lifestyle factors also play a role in reducing excess PCOS stomach fat. These include fasting, exercise, sleep, and stress reduction. If you need more help than what you can achieve on your own, speak with your doctor about a full thyroid function test. Nutritional supplements that can improve insulin sensitivity are also worth considering.
