Why PCOS Makes Weight Loss Harder

Insulin Resistance

Up to 80% of women with PCOS experience insulin resistance, which makes the body store fat more easily and burn it less efficiently.

How to help:

• Center meals around protein, fiber, and healthy fats

• Avoid high-sugar snacks and beverages

• Focus on slow-digesting carbs like lentils, oats, and sweet potatoes

Learn more from the CDC on insulin resistance.

Elevated Androgens

Women with PCOS often have higher levels of testosterone, which contributes to:

• Increased abdominal fat

• Irregular periods

• Slower muscle building

Research shows that resistance training helps lower androgen levels while improving body composition. PubMed Study

Chronic Inflammation

Low-grade inflammation is another factor. It increases cortisol and insulin, disrupts metabolism, and promotes fat storage.

Support your body by including:

• Omega-3 rich fish like salmon or sardines

• Olive oil and nuts

• Berries, leafy greens, and turmeric

Seven Steps to Lose Weight with PCOS

1. Build Balanced Plates with Protein + Fiber

Aim for:

• 25–30 grams of protein per meal

• 8–10 grams of fiber per meal

Examples:

• Eggs with sautéed greens and avocado

• Grilled chicken with lentils and roasted vegetables

• Tofu stir-fry with brown rice and broccoli

2. Create a Gentle Calorie Deficit

Drastically slashing calories can harm your metabolism and worsen hormone balance.

Instead:

• Reduce daily intake by 250–400 calories

• Track eating patterns for one week

• Avoid skipping meals

3. Strength Train 3–4 Times Per Week

Strength training improves insulin sensitivity, builds lean muscle, and increases metabolic rate.

Start with:

• Squats

• Rows

• Presses

• Deadlifts

Add walking or low-impact cardio to support recovery and stress management.

4. Time Carbs Around Workouts

Eat most of your carbohydrates:

• 1–2 hours before a workout

• Within 2 hours after for recovery

Great options:

• Quinoa and chicken post-workout

• Oats and berries pre-workout

Limit high-carb meals late at night to support overnight fat burning.

5. Focus on Anti-Inflammatory Fats

Healthy fats to include:

• Extra-virgin olive oil

• Avocados

• Chia and flax seeds

• Wild salmon

Limit processed seed oils like soybean and corn oil.

Try practitioner-grade options from Thorne Supplements.

6. Improve Sleep and Manage Stress

Sleep and stress control are essential for hormone regulation.

Aim for:

• 7–9 hours of restful sleep

• No caffeine after 2 PM

• Daily breathwork, journaling, or mindfulness

Check out the Mind-Body Nutrition Workbook to support this habit.

7. Consider Evidence-Based Supplements

Top PCOS-friendly supplements include:

• Myo-inositol & D-chiro-inositol: Improves insulin sensitivity

• Magnesium glycinate: Supports blood sugar and sleep

• Omega-3s: Reduces inflammation
