Why Diet Matters for PCOS and Weight Loss
For many women, weight loss with PCOS feels like an uphill battle. The challenge often comes down to insulin resistance, hormone imbalance, and inflammation. A tailored diet can help manage these underlying drivers, making it easier to lose weight and feel better.
PCOS and Insulin Resistance
Up to 70% of women with PCOS experience insulin resistance (NIH). This leads to higher insulin levels, increased fat storage, and difficulty losing weight. Diets built on high-fiber carbs, lean protein, and healthy fats can improve blood sugar control and support weight management.
Inflammation and Hormonal Imbalance
PCOS is also linked to chronic low-grade inflammation. This worsens hormonal symptoms like irregular cycles, acne, and fatigue. Anti-inflammatory foods such as olive oil, vegetables, berries, and omega-3 rich fish can reduce inflammation and improve outcomes (PubMed).
Top Diets for PCOS Weight Loss
Low GI Diet for PCOS
A low glycemic index (GI) diet focuses on foods that don’t spike blood sugar. Examples include quinoa, beans, lentils, and non-starchy vegetables.
Research shows that women following a low GI diet lose more weight and improve cycle regularity compared to a standard healthy diet (AJCN).
See my PCOS Grocery List for easy swaps to build meals around low GI foods.
Mediterranean Diet and PCOS
The Mediterranean diet emphasizes whole foods, produce, legumes, nuts, fish, and olive oil. It limits processed foods and added sugars.
This approach supports healthy weight loss, reduces inflammation, and improves insulin sensitivity (Harvard).
Example meal: grilled salmon with quinoa, roasted zucchini, and olive oil.

Keto Diet for PCOS
The keto diet is very low carb and high fat. It may reduce insulin levels and promote short-term weight loss (PubMed).
However, keto can be restrictive and difficult to maintain. Some women experience nutrient gaps or cravings when reintroducing carbs.
Learn more in my PCOS Weight Loss Nutrition Guide, where I compare keto and Mediterranean strategies side by side.
Other Approaches
DASH diet: Focuses on blood pressure and heart health but also improves insulin sensitivity.
Plant-forward diets: Can work well if balanced with protein sources like tofu, lentils, or edamame.
The key is sustainability—choose an approach you can follow long term.
Practical Nutrition Tips for PCOS Weight Loss
Build Balanced Plates
Divide meals into three parts: protein, high-fiber carbs, and vegetables. Add healthy fats like avocado or olive oil for satiety.
The PCOS Plate Formula: ½ non-starchy vegetables + ¼ lean protein + ¼ complex carbs + 1–2 tbsp healthy fat
Simple, visual, and sustainable — this formula helps reduce insulin spikes, keeps you full, and supports steady energy.
Snack Smart
Pair protein with fiber to keep blood sugar stable. Examples:
Greek yogurt with chia seeds
Hummus with raw veggies
Boiled eggs with fruit

Beyond Diet
Exercise, sleep, and stress management are just as important as food. Strength training improves insulin sensitivity and helps preserve lean muscle (NIH).
