Polycystic ovarian syndrome (PCOS) can negatively affect your gut health, lead to unwanted weight gain, and increase the risk of diabetes, obesity, and cardiovascular diseases. The good news is that you can make lifestyle and dietary changes to manage your symptoms, get back in shape, and improve your long-term health.
This article will teach you how to adopt a PCOS diet plan that is both sustainable and effective.
What Is a PCOS Diet?
A PCOS diet is designed to relieve symptoms by controlling glucose spikes and optimizing insulin and androgen levels. Consuming whole foods rich in fiber and lean protein while limiting refined carbohydrates, sugar, and processed foods is the most effective dietary strategy.
Non-starchy vegetables, low-glycemic carbohydrates, whole grains, lean protein, and fiber-rich foods prolong satiety, slow the release of glucose, and stabilize blood sugar levels. They fuel the body for longer periods and prevent overeating and unhealthy snacking.
Many PCOS patients struggle with insulin resistance, a condition that destabilizes glucose levels and makes weight loss even more difficult. To avoid blood sugar spikes, eat smaller, well-balanced meals at regular intervals.
For maximum results, create an eating plan that aligns with your circadian rhythm (i.e., the sleep-wake cycle) and adjusts your caloric intake based on your activity levels.
PCOS-Friendly Foods
No single food can miraculously relieve PCOS symptoms on its own. The goal is to make small, sustainable adjustments that improve the overall quality of your diet.
The following table highlights PCOS-friendly food choices:
What to include PCOS-related benefits Sources
Fiber Slows down digestion, improves insulin sensitivity, relieves dysbiosis symptoms, boosts metabolism, lowers insulin secretion, and decreases testosterone levels. Cauliflower, broccoli, Brussel sprouts, kale, spinach, arugula, red-leaf lettuce, pumpkin, peppers, beans, lentils, sweet potatoes, winter squash, whole grains, almonds, apples, and berries.
Lean proteins Increase satiety, reduce cravings, stabilize blood sugar levels, improve insulin sensitivity, and support metabolic health. Chicken breast, pork loin, tofu, fish, beans, legumes, lentils, nuts, chickpeas, eggs and egg whites, Greek yogurt, and cottage cheese.
Omega-3 Regulate the menstrual cycle, improves fertility, lowers insulin resistance, reduces inflammation, lowers androgens, and reduces acne and excessive hair growth. Salmon, sardines, mackerel, anchovies, walnuts, shellfish, olive oil, flaxseed, chia seeds, and soybeans.
Anti-inflammatory foods Restore hormonal balance and improve fertility and menstrual regularity by reducing acute and chronic inflammation. Cruciferous vegetables, tomatoes, olive oil, green leafy vegetables, berries, citrus fruits, whole grains, nuts, seeds, avocados, and fatty fish.
Non-starchy vegetables Assist in weight management and enhance insulin sensitivity because they are low in calories, high in fiber, and have a low glycemic index. Lettuce, kale, spinach, endives, tomatoes, mushrooms, broccoli, cauliflower, peppers, celery, fennel, green beans, and snow peas.
Whole grains Increase the feeling of fullness, aid digestion, and slow the absorption of sugar. Brown rice, barley, sorghum, oatmeal, quinoa, whole-grain pasta, wild rice, buckwheat, millet, and bulgur.
Foods to Avoid with PCOS
Limit or eliminate foods that increase inflammation, worsen insulin resistance, and lead to sugar spikes, such as the following:
- Highly processed foods - Packaged snacks, frozen pizzas, instant noodles, sweetened yogurts, mass-produced breads, ready-to-eat meals, processed meats, biscuits, and condiments.
- Refined carbohydrates - White bread, white rice, sugary drinks, store-bought granola, processed snacks, energy bars, crackers, pretzels, pizza dough, bagels, rolls, and ketchup.
- Sugary foods and beverages – Cookies, candy, cakes, sweetened yogurts, ice cream, breakfast cereals, cereal bars, ketchup, sodas, sports drinks, teas, and sweeteners such as dextrose, sucrose, and corn syrup.
- White flour – White bread, pastries, cakes, cookies, pancakes, waffles, doughnuts, noodles, wraps, flatbreads, pizza crust, pasta, and rolls.
- Starchy vegetables - White potatoes, sweet potatoes, corn, peas, beans, yams, butternut, plantains, and winter squash.
- Fried foods – Potato chips, French fries, corn chips, fried chicken or fish, churros, fried okra, doughnuts, tempura, chicken nuggets, and arancini.
- Trans fats and saturated fats – Butter, margarine, fried fast food, shortening, baked goods, fatty meats, high-fat cream, and cheese.
- Red meat – Roast beef and steaks, hamburgers, hot dogs, and processed luncheon meat.
- Processed foods – Cakes, cookies, candy, pies, snacks, canned fruit and vegetables, frozen food, breakfast cereals, deli meats, instant noodles, sauces, canned tuna, pre-packaged cereals, and condiments.
- Alcoholic drinks - Beer, gin, vodka, rum, whiskey, brandy, wine, tequila, and other fermented alcoholic beverages.
Avoid fad diets that promise quick fixes or eliminate entire food groups, such as carbohydrates. Restrictive diets can trigger a yo-yo effect and may have long-term health consequences.
While intermittent fasting may support metabolic health in some healthy individuals, there is no conclusive evidence that it improves PCOS symptoms. In fact, limiting your eating to a short time window can increase the risk of binge eating high-calorie foods, which may worsen hormonal imbalances and trigger PCOS flare-ups.
Popular PCOS Diet Approaches
Depending on your preferences and health goals, you can pick among several PCOS-friendly diets. While none offer quick results, consistent meal planning in consultation with a licensed nutritionist can improve metabolism, balance hormones, and reduce PCOS symptoms.
Mediterranean Diet
The Mediterranean diet is a plant-based diet that emphasizes healthy fats, whole grains, fruits, vegetables, fish, and moderate consumption of cheese and red meat. This eating pattern eliminates saturated fats, processed meats, and refined sugar, thereby lowering inflammation.
According to this study, the Mediterranean diet has potent therapeutic effects in PCOS treatment when combined with a low-carb diet, and a wide variety of fiber-rich foods makes it preferable to other overly restrictive diets.
DASH Diet
DASH (Dietary Approaches to Stop Hypertension) is a flexible diet that supports the cardiovascular system, stabilizes blood pressure, and reduces the risk of type 2 diabetes. Since PCOS increases the risk of hypertension, doctors often prescribe it as a prevention and a weight management aid.
This heart-healthy eating plan focuses on whole fruits, vegetables, and grains, fish, poultry, beans, nuts, and low-fat dairy, while limiting saturated fats, full-fat dairy, fatty meats, and sweetened beverages.
High-Protein Diet
High-protein diets emphasize protein-rich foods to support muscle recovery, promote weight loss, boost metabolism, and improve insulin sensitivity. These eating plans differ in their recommended carbohydrate intake. Common examples include the Atkins, keto, paleo, and carnivore diet.
For individuals with PCOS, high-protein diets with moderate carbohydrate intake are often preferred, as they help stabilize blood sugar levels and manage cravings. Excellent protein sources include lean meats, fish, eggs, legumes, tofu, dairy products, nuts, and seeds.
Metabolic Diet
A metabolic diet is a weight-loss dietary approach that increases metabolism, accelerates fat burn, and reduces cravings. Other health benefits include increased energy, lower risk of type 2 diabetes and cardiovascular disease, and optimal blood sugar and cholesterol levels.
In addition to improving their metabolic health, this diet benefits PCOS patients because it’s well-balanced, nutrient-dense, and diverse.
Note: Learn about the connection between hormones and metabolism.
Low-Glycemic Index Diet
A low-glycemic index (low-GI) diet aims to stabilize blood sugar levels, support weight loss, and lower the risk of heart disease and type 2 diabetes. It focuses on foods that cause a slower, more gradual rise in blood glucose, such as non-starchy vegetables, legumes, whole grains, and fruits like apples and berries.
Because this eating pattern prevents glucose spikes and improves insulin sensitivity, many PCOS patients follow it to ease symptoms and lower the risk of related health complications.
Lifestyle Changes to Support a PCOS Diet
Dietary adjustments paired with healthy lifestyle changes can help you manage the symptoms of PCOS while lowering the risk of other health conditions.
The following lifestyle habits can significantly improve your PCOS when combined with a balanced diet.
Meal Timing
Eat regularly, every three to five hours throughout the day, to maintain stable blood sugar levels. Skipping meals can lead to glucose spikes, cravings, and overeating, all of which may disrupt hormonal balance and worsen PCOS symptoms.
Aim for three balanced meals and two healthy snacks each day, gradually reducing your calorie intake toward the evening. Research suggests that consuming a larger, protein-rich breakfast can help regulate insulin levels throughout the day, resulting in lower testosterone levels, improved insulin sensitivity, and regular ovulation.
Portion Control
Smaller, balanced portions rich in fiber, nutrients, and protein keep you fuller longer without compromising your health goals. Pay attention to your typical serving sizes to identify eating patterns and discover opportunities to improve portion control.
A simple visual guide is to imagine your plate divided into sections: half filled with non-starchy vegetables, one-quarter with lean proteins, and one-quarter with whole grains and healthy fats. This approach helps you balance your meals and meet your nutritional needs without overeating.
Improved Sleep
Poor sleep habits increase inflammation and trigger hormonal fluctuations, leading to chronic insomnia and PCOS flare-ups. Studies show that PCOS patients are more prone to sleep disorders, and scientists have linked inadequate sleep to obesity, insulin resistance, cardiovascular disease, and depression.
Aim for seven to eight hours of quality sleep every night to reduce insulin resistance, balance hormones, and support overall physical and mental well-being.
Stress Reduction
Chronic or excessive stress can disrupt hormonal activity, disturb gut function, increase inflammation, and contribute to weight gain, all of which can worsen PCOS symptoms.
Engaging in stress-relieving activities such as gentle stretching, yoga, breathing exercises, painting, reading, or walking in nature eases tension, lowers cortisol levels, and supports recovery and hormonal balance.
Note: Read about vagus nerve stimulation, a powerful relaxation technique that may alleviate some PCOS-related symptoms.
Physical Activity
A lack of physical movement contributes to weight gain, hormonal imbalances, diabetes, heart disease, and insulin resistance. Prolonged sitting leads to metabolic dysfunction and aggravates PCOS-related cramping, bloating, and pelvic pain.
To manage PCOS, fitness experts recommend at least 30 minutes of cardio and strength training each day, five days a week. Avoid strenuous or high-intensity workouts to prevent cortisol spikes, fatigue, and injuries.
PCOS Diet and Nutritional Supplements
Nutritional supplements can enrich your diet and deliver a range of additional health benefits. Don’t forget to consult a medical professional before adding new supplements to your regimen to prevent adverse effects or complications.
Complement your PCOS diet with the following dietary supplements:
- Hormone support – Optimize your hormonal status with hormone-balancing vitamins and minerals, such as Vibrant Thyroid Support.
- Gut relief – Promote a healthy gut flora with Vibrant Biome to reduce inflammation, improve insulin sensitivity, and support the gut-brain-hormone axis.
- Metabolism boosters – Speed up your metabolic rate to maintain a healthy BMI with vitamin B IV therapy and other metabolism-boosting supplements.
- Vitamin and mineral supplements – Increase nutrient absorption, boost the immune system, and reduce oxidative stress with supplements such as Vibrant B or Vibrant C.
