The underlying causes of PCOS are still not fully understood, but it involves insulin resistance, inflammation, and hormonal imbalances. This translates into a higher risk of developing type 2 diabetes, heart disease, and other metabolic diseases. Nutrition plays a role in managing these conditions by targeting the root causes of PCOS. Many individuals with PCOS have higher-than-normal levels of insulin, often due to poor diet or genetics. High insulin levels can lead to increased production of androgens — male hormones that are present in both men and women, but in excess in women with PCOS.

For women with PCOS, the nutritional focus shifts towards a diet that helps manage insulin levels, reduce inflammation, and support a healthy balance of hormones. This approach is often referred to as the “PCOS diet.”

The PCOS diet doesn’t look the same for everyone, and it’s a matter of trial and error to find what works best for your body. However, there are some general principles that can be a starting point for designing a nutrition plan that’s special to you.

The Role of Macronutrients

Balancing macronutrients – carbohydrates, protein, and fat – can have a powerful impact on managing PCOS.


The right types of carbs and the right portion sizes can improve how your body responds to insulin. High-fiber, unprocessed carbohydrates like whole grains, fruits, and vegetables are ideal. These foods help keep your blood sugar levels stable, reduce insulin spikes, and aid in digestion, which is essential because many women with PCOS also experience gastrointestinal issues.


Including lean proteins in your diet can help manage metabolism, energy levels, and build and repair body tissues. Good sources of lean protein include chicken, turkey, fish, and plant-based options like beans, lentils, and tofu.


Dietary fats are crucial for hormone balance and overall health. Healthy fats found in avocados, nuts, seeds, and olive oil can be especially beneficial for women with PCOS. However, it’s important to monitor your intake as fats are calorie-dense, and excess calories can contribute to weight gain, which may exacerbate PCOS symptoms.

Micronutrients and Nutrient-Dense Foods

Focusing on nutrient-dense foods rich in vitamins and minerals, particularly those that are found to be deficient in women with PCOS, can support overall health and help manage symptoms.

Vitamin D

Many women with PCOS have low levels of vitamin D. Adequate sunlight and dietary sources of vitamin D like fatty fish, egg yolks, and fortified dairy and soy products can help maintain healthy levels.


Magnesium is an essential mineral that supports over 300 enzyme systems in your body. Research suggests that magnesium may improve insulin resistance in women with PCOS. Good sources include spinach, almonds, and black beans.

Omega-3 Fatty Acids

Omega-3s have anti-inflammatory properties, which can be helpful for women with PCOS due to the link between inflammation and insulin resistance. Fatty fish like salmon, flaxseeds, and walnuts are rich sources.

How to Manage Your Weight With PCOS

Weight management is a significant aspect of controlling PCOS symptoms, and effective weight management strategies include a combination of dietary choices and physical activity.

Portion Control

Maintaining a healthy weight involves balancing the calories you consume with the energy your body burns. Portion control is a simple but effective method to manage your intake.

Eating Habits

Practicing mindful eating, avoiding emotional eating, and being aware of hunger and satiety cues can support weight management and emotional health.

Physical Activity

Incorporating regular physical activity into your routine can help with weight loss and managing PCOS symptoms. A combination of aerobic exercises and strength training can be beneficial.

The Impact of Sugar and Processed Foods

High sugar and processed foods can lead to spikes in blood sugar levels and may worsen insulin resistance. Conversely, whole foods and natural sugars found in fruits can moderate these spikes and provide a more gradual energy release.


Limiting the intake of added sugars is crucial. This means reducing the consumption of sugary drinks, desserts, and processed foods.

Processed Foods

Processed foods often contain harmful trans fats and high levels of sugar and salt. These can contribute to weight gain and inflammation. Opt for whole, unprocessed foods as much as possible.

Mindful Eating and PCOS

Mindful eating involves being fully present and attentive to the what, where, and how of eating. This practice can be especially beneficial for individuals with PCOS.

Emotional Eating

PCOS can affect mental health, and emotional eating is not uncommon. Developing a toolkit of strategies to manage emotions without using food – such as journaling, talking to a friend, or engaging in a hobby – can help you eat more mindfully.

Food Choices

Making deliberate and thoughtful food choices can lead to feeling more in control of your health and your PCOS. Consistently choosing foods that you know support your body’s needs can be very empowering.

The Gut Microbiome

Emerging research is exploring the role of the gut microbiome in PCOS. Maintaining a healthy gut is associated with hormonal balance and weight management.

Probiotics and Fermented Foods

Incorporating probiotics through supplements or fermented foods like yogurt, kefir, and kimchi can support the diversity of your gut microbiome.


Prebiotic foods like garlic, onions, and asparagus can also support a healthy gut by providing nourishment for beneficial gut bacteria.

Long-term Changes and Sustainability

Making lifestyle changes, including dietary adaptations, should be sustainable over the long term. This means implementing shifts that you can maintain, rather than quick fixes or extreme diets.

Education and Support

Educating yourself about your condition and nutrition is key to making long-term changes. Seeking support from healthcare providers, nutritionists, or support groups can provide guidance and encouragement.

Tracking Progress

Monitoring your symptoms and how they respond to dietary changes is essential. Keep a journal or use a tracking app to record your progress and identify patterns that work for you.

PCOS is a complex condition, and there’s no one-size-fits-all approach to managing it. However, the evidence is clear that nutrition plays a crucial role. By making informed and intentional choices about the foods you eat, you can take control of your health and reduce the impact of PCOS on your life. Remember, small changes can lead to significant improvements, so start with what feels achievable and build from there.
