MyFitnessPal

MyFitnessPal is the world's most widely used food and calorie tracking app, with over 200 million users and the largest food database available — more than 14 million foods. For women managing PCOS, MyFitnessPal is one of the most practical tools available. Since insulin resistance affects an estimated 70–80% of women with PCOS, tracking carbohydrate intake, glycemic load, and macronutrients is not optional — it's foundational. MyFitnessPal makes food tracking for PCOS diet management fast, flexible, and sustainable.

Why It Helps With PCOS

PCOS and food are deeply connected. Insulin resistance means the body struggles to process carbohydrates efficiently, leading to elevated blood sugar, elevated androgens, and worsened PCOS symptoms including irregular cycles, weight gain, acne, and fatigue. Food tracking with MyFitnessPal creates direct visibility into the carbohydrates and sugar driving insulin spikes.

MyFitnessPal lets you set custom macro targets, which is critical for PCOS. A low-carb or low-GI eating approach is commonly recommended — but you need data to follow it. MyFitnessPal gives you that data, meal by meal. You can also track fiber (25–30g/day is recommended for PCOS gut health), monitor sodium (affects PCOS-related bloating), and flag trigger foods that correlate with symptom flares.

How to Use MyFitnessPal for PCOS

1. Set custom macro goals — Go to Goals → Custom Macros. For insulin-resistant PCOS, aim for approximately 40% carbohydrate, 30% protein, 30% fat. Adjust based on your dietitian's guidance.
2. Track net carbs daily — Use the Nutrition Dashboard to monitor carb intake meal by meal. Look for days where carbs exceed your target and identify which foods caused it.
3. Barcode-scan everything — The barcode scanner makes logging fast enough to be consistent. Log within 30 minutes of eating while the meal is fresh.
4. Track fiber separately — Add fiber as a tracked nutrient in Settings. Women with PCOS benefit from high-fiber diets to slow glucose absorption and support gut microbiome health.
5. Log symptoms in Notes — Use the daily Notes field to record PCOS symptoms (acne, bloating, energy levels). After 4–6 weeks, review alongside your food log to identify patterns.
6. Sync with your health ecosystem — Connect to Apple Health, Garmin, Fitbit, or a CGM (continuous glucose monitor) app to correlate food data with activity and glucose response.

How It Compares

Cronometer offers more detailed micronutrient tracking, which is useful for monitoring PCOS-relevant nutrients like magnesium, zinc, and vitamin D. But MyFitnessPal's overwhelming advantage is its food database size — you'll find virtually every food you eat already logged. For most PCOS women, MyFitnessPal is the better starting point. If you're deep into supplement and micronutrient optimization, consider layering in Cronometer for spot-checks.

If you're looking for PCOS-specific symptom tracking rather than food logging, PCOS Polly was built specifically for that purpose and pairs well with MyFitnessPal.

Getting Started

Download MyFitnessPal free on iOS and Android. The free tier covers everything most PCOS women need — custom macros, food logging, and nutrient tracking. Premium ($19.99/month or $79.99/year) adds meal planning, food analysis, and macro-based suggestions. Start by logging everything for two weeks before making any dietary changes. The data will show you exactly where your carbohydrates are coming from — and that's where PCOS management begins.
