Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age. It can disrupt menstrual cycles, fertility, and even impact your appearance. Beyond these issues, PCOS elevates the risk of obesity, heart disease, and diabetes. Making informed dietary choices is crucial for managing PCOS symptoms and mitigating long-term health risks.
Understanding the Impact of Diet on PCOS
Diet, exercise, and getting enough sleep are key to reducing the effects of PCOS, according to Shruthi Mahalingaiah, MD, MS, a reproductive endocrinologist/gynecologist at Mass General Brigham and director of the Ovulation Health Clinic at the Fertility Center at Mass General Hospital.
“Health optimization in people with PCOS is sensitive to a lot of things — especially the things we eat and drink, our sleep-wake cycle, and physical activity,” she says. “Start with a balanced diet of whole, fresh foods as much as possible and limit ultra-processed foods. And put that diet into context of your circadian rhythms (your sleep-wake cycle). This means eating when you’re having the most activity, because that’s when your body needs the energy and can burn off excess blood sugar.”
Adopting this approach can assist in regulating blood glucose levels, which in turn influences insulin and androgen levels. By carefully considering what you eat, you can effectively manage PCOS symptoms and minimize potential health complications.

Foods to Limit or Avoid with PCOS
To effectively manage PCOS through diet, it’s essential to understand which foods can exacerbate symptoms. Insulin resistance is a central issue in PCOS, and certain foods can worsen this condition, leading to elevated blood sugar and androgen levels. Here’s a breakdown of food groups and specific items to limit or avoid:
1. Refined Carbohydrates
Refined carbs are quickly broken down into glucose, causing rapid spikes in blood sugar and insulin levels. This can worsen insulin resistance and contribute to weight gain.
- White bread, pasta, and rice: Opt for whole-grain alternatives like brown rice, quinoa, or whole-wheat pasta.
- Pastries and sugary cereals: These are high in sugar and offer little nutritional value.
- Processed snacks like chips and crackers: Choose healthier snack options like nuts, seeds, or vegetables with hummus.
2. Sugary Drinks
Sugary drinks are a major contributor to insulin resistance and weight gain. They provide empty calories and can lead to blood sugar crashes.
- Soda: A single can of soda can contain more than the recommended daily intake of added sugar.
- Juice: Even 100% fruit juice can be high in sugar. Choose whole fruits instead, which contain fiber to help regulate blood sugar.
- Sweetened tea and coffee: Be mindful of added sugars in your beverages. Opt for unsweetened versions and add natural sweeteners like stevia if needed.

3. Processed Foods
Processed foods are often high in unhealthy fats, sugar, and sodium, and low in nutrients. They can contribute to inflammation and worsen insulin resistance.
- Fast food: Limit your intake of fast food, which is typically high in calories, unhealthy fats, and sodium.
- Frozen meals: Many frozen meals are heavily processed and contain added sugars and sodium.
- Processed meats: Bacon, sausage, and deli meats are high in saturated fat and sodium.
4. Unhealthy Fats
Certain fats, particularly saturated and trans fats, can contribute to inflammation and insulin resistance.
- Fried foods: Fried foods are often high in unhealthy fats and calories.
- Fatty cuts of meat: Choose leaner cuts of meat like chicken breast or fish.
- Processed snacks: Many processed snacks contain unhealthy trans fats.
Focusing on a PCOS-Friendly Diet
While it’s important to know what foods to avoid, it’s equally important to focus on incorporating foods that can help manage PCOS symptoms. A PCOS-friendly diet should be rich in whole, unprocessed foods, including:
- Lean protein: Chicken, fish, beans, and lentils.
- Complex carbohydrates: Brown rice, quinoa, and whole-wheat bread.
- Healthy fats: Avocados, nuts, seeds, and olive oil.
- Fiber-rich fruits and vegetables: Berries, leafy greens, and cruciferous vegetables like broccoli and cauliflower.
Dietary Changes for PCOS Management
Managing PCOS symptoms effectively involves understanding the link between diet, insulin resistance, and hormone balance. By limiting or avoiding refined carbohydrates, sugary drinks, processed foods, and unhealthy fats, and focusing on a diet rich in whole, unprocessed foods, you can significantly improve your symptoms and long-term health. Consulting with a registered dietitian or healthcare professional can help you create a personalized meal plan that meets your individual needs and helps you manage PCOS effectively.
