What Is Polycystic Ovary Syndrome?

Polycystic ovarian syndrome (PCOS) is a hormonal disorder that affects up to 20% of women of reproductive age worldwide (1). This hormonal imbalance is often considered to be strictly a reproductive health concern, however, it’s actually an endocrine disorder that may cause reproductive issues in some people.

Insulin resistance, chronic inflammation, and high levels of androgens (male hormones) like testosterone are associated with the condition.  

Some common symptoms of PCOS include:

• Hirsutism (unwanted and excessive hair growth)
• Hair loss
• Acne
• Irregular periods
• Weight gain
• Infertility

PCOS is also associated with fatigue, depression, anxiety, sleep disturbances, and a higher risk for other medical conditions such as type 2 diabetes, high blood pressure, high cholesterol, fatty liver, and heart disease (2, 3). 

PCOS: Why Your Diet Matters

Although the exact cause of PCOS remains unknown, researchers believe that several driving factors are at the core of PCOS. These driving factors are insulin resistance, inflammation, and adrenal dysfunction. Someone with PCOS may have one or more of these factors causing their symptoms. 

The good news is that the foods you eat can have a direct influence on your hormone health. Diet and lifestyle changes play a crucial role when it comes to managing your PCOS and reducing your chances of developing other health conditions, such as type 2 diabetes and cardiovascular disease. 

Including high quality, nutrient-dense foods can improve insulin sensitivity, reduce inflammation, and ultimately improve your quality of life. On the other hand, unhealthy foods could potentially lead to high blood sugar levels, inflammation, more health issues, and essentially worsen your PCOS symptoms.

PCOS: Why Lifestyle Changes Matter

This post isn’t focusing on lifestyle changes but I couldn’t let this go unsaid. Don’t underestimate the power of lifestyle factors – it really does take a whole body approach to manage PCOS symptoms. Regular exercise, quality sleep, and stress management are all important pieces of the puzzle when it comes to leading a healthy lifestyle and balancing your hormones. 

Several different types of physical activity can be beneficial including:

• Walking
• High intensity interval training
• Resistance training
• Yoga

Let’s dive into what we know about PCOS diets. 

What Is The Best Diet For PCOS?

There’s a lot of debate as to whether a plant-based diet, low glycemic diet, ketogenic diet, anti-inflammatory diet, low-carb diet, calorie deficit, vegan diet, or even intermittent fasting is the best option for PCOS.

The truth: researchers have not determined a single best diet for PCOS. 

PCOS Diet For Weight Loss

Since weight management can be difficult with PCOS, many people are often searching for the best way to lose weight…which usually leads to a discussion on two popular diets: intermittent fasting and the keto diet. 

Research has shown that both of these diets can lower body weight and body fat, lower testosterone levels, and regulate menstrual cycles. While the results for these diets have been mostly favorable, these research studies don’t necessarily show better results than traditional healthy eating approaches.

It’s really important to note that the research on intermittent fasting and ketogenic diets is pretty limited. The few research studies we have used extremely small sample sizes, were conducted over short time periods, and had high dropout rates (likely because these diets weren’t sustainable for those who dropped out) (4, 5, 6). 

Since weight loss can be difficult with PCOS, we frequently see yo-yo dieting, and subsequently weight cycling. Weight cycling, or repeatedly losing weight and re-gaining it, leads to worsened insulin resistance and cardiovascular health (4). 

This is a key point to consider when deciding to try a new diet. If you want lasting results, you need a realistic and sustainable approach. Ultimately, the best diet for PCOS is the one that you can do for the long-term. 

My take on all of this? I recommend a balanced PCOS diet approach that includes mostly whole foods and focuses on blood sugar management and reducing inflammation. We know that this can provide the most benefits for overall good health. You could say that my approach is most similar to the Mediterranean diet or the DASH diet.

Foods To Eat With PCOS

A PCOS-friendly diet includes a variety of whole foods from different food groups. This is an easy way to ensure that you’re hitting on a wide range of nutrients that are beneficial for PCOS.

Foods To Avoid With PCOS

There aren’t any foods that everyone who has PCOS needs to avoid entirely. Balance is the key to an overall healthy diet that is sustainable. That said, it’s helpful to prioritize certain foods more frequently, such as those listed in the section above. 

The foods listed below, when eaten in large quantities or very frequently, may worsen insulin resistance or inflammation. 

Limit the following foods: 

• Highly processed foods and meats: fast food, potato chips, pretzels, sausage, hot dogs, bacon, highly processed deli meat such as salami
• Sugary drinks: soft drinks such as regular soda, sweetened tea, energy drinks, fruit juices
• Sugary foods or foods with high amounts of added sugars: pastries, cookies, cakes, pies, candy

A well-balanced diet is often the most sustainable type of approach and allows most PCOS patients to reach their health goals. Meal planning may be helpful to achieve your goals. 

Nutritious foods to eat with PCOS: lean protein, fatty fish, fruits, vegetables, whole grains, legumes, nuts, seeds, and olive oil.

Foods to limit or avoid with PCOS: processed foods and meats, sugary drinks, refined grains, foods with high amounts of added sugars. Alcohol consumption should be limited or avoided entirely.
