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

🧭 Personalized > Perfect

There’s no one “PCOS diet.” But there is a smarter starting point.

🎯 Use the PCOS Calorie Adjuster to:

  • Find your realistic daily calorie target
  • Avoid the plateau trap
  • Reduce the guesswork
