The Truth About Eating for PCOS: Why Calorie Calculators Often Get It Wrong

If you have PCOS and you’ve tried using a standard calorie calculator, you’ve probably felt frustrated.
“I’m eating in a deficit… so why am I not losing weight?”
You're not imagining things. Most calorie calculators don’t account for insulin resistance, which affects up to 70% of women with PCOS.
Let’s talk about why that matters—and how our PCOS Calorie Adjuster does it differently.
🤔 Why Standard Calorie Calculators Fall Short
Most tools use formulas like Harris-Benedict or Mifflin-St Jeor to estimate your calorie needs based on height, weight, age, gender, and activity.
But here’s the catch:
- They assume average insulin sensitivity
- They ignore hormonal imbalances
- They don’t adapt for metabolic dysfunction
Which means you could be eating exactly what it says and still not getting results.
🧬 PCOS and Insulin Resistance: A Hidden Barrier
Here’s what insulin resistance does:
- Your body produces more insulin to manage blood sugar
- High insulin promotes fat storage, especially around the belly
- It also makes your body less responsive to normal weight loss triggers
This means your “caloric needs” may be 10–20% lower than someone without PCOS—even if you weigh the same.
💡 Smarter Calorie Adjustments for PCOS
Our PCOS Calorie Adjuster does something different:
✅ Starts with standard BMR calculation
✅ Then adjusts for insulin resistance using a metabolic correction factor
✅ Recommends a gentler deficit to avoid hormone crashes
✅ Provides sustainable targets, not starvation

🔥 Bonus: Macros That Work for PCOS
While every body is different, most users with PCOS respond better to:
- Higher protein (25–30%)
- Moderate healthy fats (40–50%)
- Lower carbs (20–30%), not necessarily full keto
This supports:
- Satiety
- Blood sugar balance
- Less inflammation
