Polycystic Ovary Syndrome (PCOS) is often linked with insulin resistance, a condition where the body’s cells don’t respond properly to insulin, leading to higher blood sugar levels. This can worsen hormonal imbalances, increase androgen production, and contribute to symptoms like weight gain, acne, and irregular periods.
The glycemic index (GI) measures how quickly a food raises blood sugar after eating. Low-GI foods digest more slowly, releasing glucose gradually into the bloodstream, which helps maintain stable insulin levels — a key factor in managing PCOS.
Benefits of a Low-GI Diet for PCOS
- Reduces insulin spikes that trigger excess androgen production
- Helps regulate menstrual cycles by improving hormonal balance
- Supports weight management by keeping you fuller for longer
- Decreases inflammation, which can aggravate PCOS symptoms
- Improves energy stability throughout the day

FAQs About Low-GI Foods and PCOS
1. Do I have to cut out all high-GI foods?
No, but they should be occasional treats, balanced with protein or fat to reduce their impact.
2. Is a low-GI diet the same as low-carb?
Not exactly — low-GI focuses on carb quality and blood sugar response, not cutting carbs completely.
3. How soon will I see changes?
Many women notice reduced cravings, better energy, and more stable cycles within 6–8 weeks.
4. Can I follow a low-GI diet if I’m vegetarian?
Yes — plant-based proteins like lentils, tofu, and tempeh fit perfectly in a low-GI PCOS plan.
