If you have PCOS, you've probably heard your doctor mention insulin resistance at some point. It can feel overwhelming, especially when you're trying to figure out what to actually eat every single day. The good news? A low GI (glycemic index) diet is one of the most well-supported approaches for managing PCOS symptoms, and the best part is, it works beautifully with Filipino ingredients.
This meal plan was put together with women in the Philippines in mind. You won't find anything here that requires a trip to a specialty store or costs a fortune. Everything is practical, satisfying, and genuinely good for your hormones.
What Is the Glycemic Index and Why Does It Matter for PCOS?
The glycemic index ranks foods based on how quickly they raise your blood sugar after eating. Foods with a high GI (like white rice and white bread) cause a fast spike in blood sugar, which then triggers a surge of insulin. For women with PCOS, this is a problem because many of us already have some degree of insulin resistance, meaning our bodies produce more insulin than they should to do the same job.
Too much insulin stimulates the ovaries to produce more androgens (male hormones like testosterone). That's what drives a lot of the symptoms you're probably dealing with: irregular periods, acne, hair thinning, and weight gain that won't budge no matter what you try.
Eating low GI foods slows down the release of glucose into your bloodstream, keeps insulin levels steadier, and takes some of that pressure off your ovaries. Over time, this can lead to more regular cycles, clearer skin, less bloating, and more stable energy throughout the day.
What are Low GI Swaps for Common Filipino Foods
Before we get into the meal plan, here are some easy swaps that make a big difference:
White rice swap to brown rice, red rice, or cauliflower rice
White bread (tasty bread) swap to whole wheat pandesal or oatmeal
Instant noodles swap to mung bean vermicelli (sotanghon) or whole wheat pasta
Sweet condensed milk swap to unsweetened almond or oat milk
White sugar swap to coconut sugar or skip entirely
Banana cue (deep-fried saba) swap to steamed saba or fresh fruit
You don't have to be perfect. Even making one or two of these swaps a day adds up over time.
7-Day Low GI PCOS Meal Plan
Day 1
Breakfast: Scrambled eggs (2 eggs) with sauteed kangkong and one slice of whole wheat pandesal. Black coffee or unsweetened barako coffee.
Lunch: Brown rice (1/2 cup cooked) with ginisang monggo (mung bean stew with malunggay and bangus flakes). Side of sliced tomatoes with bagoong-free dressing (just calamansi and a pinch of salt).
Dinner: Chicken tinola with sayote and dahon ng sili. Use chicken breast or drumstick (skin removed). Serve with 1/2 cup red rice.
Day 2
Breakfast: Oatmeal (rolled oats, not instant) cooked in water or unsweetened oat milk. Top with sliced banana (just half a banana to keep the GI lower) and chia seeds.
Lunch: Sinaing na tulingan (braised tuna) with ampalaya salad dressed with calamansi and a small amount of fish sauce. Brown rice on the side.
Dinner: Grilled pork tenderloin (low fat, not liempo) with pinakbet made with bagoong alamang used sparingly. Brown rice or skip the rice and have extra vegetables.
Day 3
Breakfast: Soft-boiled eggs with leftover brown rice (about 1/2 cup) stir-fried with garlic and baby spinach. This is basically sinangag, but made with brown rice and vegetables mixed in.
Lunch: Nilagang baka (lean beef shank broth) with cabbage, sayote, and green beans. One cup of broth with all the vegetables is very filling and low GI.
Dinner: Baked bangus stuffed with tomatoes and onions. Serve with steamed okra and half a cup of brown rice.
Day 4
Breakfast: Greek yogurt (plain, no sugar) with half a cup of fresh papaya and a tablespoon of ground flaxseed. If Greek yogurt is hard to find, use low-fat plain yogurt.
Lunch: Sinigang na hipon (shrimp sinigang) with kangkong, labanos, and eggplant. This dish is naturally very low GI. Serve with 1/2 cup brown rice.
Dinner: Ginisang tofu with oyster mushrooms and bok choy. Season with low-sodium soy sauce and garlic. One cup of cauliflower rice or 1/2 cup brown rice.
Day 5
Breakfast: Whole wheat pandesal with two tablespoons of peanut butter (no sugar added). A glass of unsweetened soymilk. One small orange or a handful of kamias.
Lunch: Chicken adobo (use skinless thighs and reduce the amount of sugar or skip it entirely, the vinegar and garlic carry the flavor). Serve with brown rice and a side salad of cucumbers and tomatoes.
Dinner: Ginataang gulay without the rice — thick coconut milk with squash (kalabasa), string beans, and eggplant. If you want rice, keep it to 1/3 cup cooked.
Day 6
Breakfast: Two soft-boiled or poached eggs with sliced avocado and cherry tomatoes. Drizzle with calamansi. Skip the rice today.
Lunch: Mongo guisado (sauteed mung beans) with malunggay and smoked fish flakes. Serve with 1/2 cup red rice.
Dinner: Baked or steamed fish fillet (tilapia, cream dory, or maya-maya) with a side of sauteed kangkong and a small serving of brown rice.
Breakfast: Overnight oats: mix 1/3 cup rolled oats with unsweetened oat milk, a tablespoon of chia seeds, and a bit of cinnamon. Refrigerate overnight and top with a few fresh blueberries or diced mango (a small amount).
Lunch: Beef caldereta made with lean beef cuts, tomato sauce, and lots of vegetables (carrots, bell pepper, potatoes kept to a minimum because they are higher GI). Serve with 1/2 cup brown rice.
Dinner: Lentil soup (you can find red or green lentils in most grocery stores). Cook with garlic, onion, tomatoes, and a bit of cumin. Lentils have a very low GI and are incredibly filling. Serve with a side of steamed vegetables.

Fresh kamias or guava
Practical Tips for Making This Work
Cook rice the night before and refrigerate it. This actually lowers the GI of rice because the cooling process changes the starch structure. Reheated cold rice has a meaningfully lower glycemic impact than freshly cooked rice.
Pair carbs with protein and fat. Never eat rice or bread alone. Always have it with a protein source (egg, fish, chicken, beans) and some fat (coconut, avocado, olive oil). This slows digestion and blunts the blood sugar spike.
Watch portion sizes more than perfection. You don't have to give up rice entirely. Just reduce your portion to 1/2 cup cooked and pair it wisely.
Eat regularly. Skipping meals triggers cortisol, which also worsens insulin resistance. Aim for three balanced meals a day, and a small snack if you get hungry between meals.
Supplement Recommendations
Some supplements are commonly recommended alongside a low GI diet for PCOS. Inositol (especially myo-inositol and D-chiro inositol) has good research behind it for improving insulin sensitivity in PCOS. Magnesium and chromium are also worth discussing with your doctor or OB-GYN. Always check with your healthcare provider before starting any supplement.
Some Final Thoughts
Managing PCOS through food is not about being on a strict diet forever. It's about building habits that work with your body instead of against it. A low GI way of eating is sustainable, practical, and genuinely effective for many women with PCOS. Start with small changes, be consistent, and give it at least 8 to 12 weeks before you expect to see results.
You've got this.
