What Is PCOS & Why Does Nutrition Matter?
PCOS is a hormonal condition that affects how your body produces and uses insulin, estrogen, and androgens. Common symptoms may include irregular periods, difficulty losing weight, acne, hair thinning, high cortisol levels, and fertility struggles.
Nutrition plays a central role in PCOS management, especially because many of its symptoms are rooted in insulin resistance and inflammation.
Key Symptoms of PCOS
- Irregular or missed periods
- Difficulty losing weight (or easy weight gain)
- Hormonal acne (often on the jawline)
- Unwanted facial/body hair
- Hair thinning
- Mood swings, fatigue, or anxiety
How Blood Sugar & Insulin Impact PCOS
Insulin resistance is one of the root causes of PCOS. When your body can’t respond well to insulin, it produces more, and that can stimulate the ovaries to make more androgens (male hormones), worsening PCOS symptoms.
Top Foods to Include in a PCOS-Friendly Diet
- Lean Proteins: Eggs, poultry, fish, legumes, to help stabilize blood sugar
- Healthy Fats: Avocados, olive or avocado oil, nuts, seeds for hormone production
- Fiber: Leafy greens, berries, whole grain carbohydrates, and lentils to improve insulin sensitivity
- Anti-inflammatory foods: Fatty fish, turmeric, ginger, berries, cruciferous vegetables
- Low-glycemic carbs: Quinoa, sweet potatoes, steel-cut oats to avoid sugar crashes
Foods That May Worsen PCOS Symptoms
- Refined sugar (soda, pastries, candy)
- Simple carbs (white bread, pasta, crackers)
- Excess dairy (can worsen acne or inflammation in some people)
- Processed meats and trans fats
- Excess caffeine and alcohol
Lifestyle Habits That Complement Nutrition
- Prioritize strength training and walking
- Get 7-9 hours of quality sleep
- Manage stress: find your daily non-negotiables that you enjoy (high cortisol can worsen PCOS)
- Avoid skipping meals; this can spike insulin later and cause crashes throughout the day
Different PCOS Types & Why They Matter
PCOS does not look the same for everyone. Understanding your type helps guide the right interventions. Common PCOS types include:
- Insulin-Resistant PCOS: Often includes weight gain, sugar cravings, and fatigue.
- Post-Pill PCOS: Occurs after stopping hormonal birth control and may include acne and irregular periods.
- Adrenal PCOS: Characterized by high DHEA levels, often stress-related.
- Inflammatory PCOS: May include fatigue, joint pain, and skin issues.
At One Nutrition Group, we personalize your plan to your specific PCOS type, dietary restrictions, and lifestyle.
How PCOS Affects Mental Health
Many people with PCOS experience anxiety, depression, or mood swings. This may be due to:
- Blood sugar instability
- Chronic inflammation
- Hormonal fluctuations (especially androgens)
- Nutrient deficiencies Supporting mental health through food, blood sugar balance, and key nutrients like B vitamins, magnesium, and omega-3s can make a major difference.
Supplements That May Support PCOS (With Guidance)
- Inositol (especially Myo-Inositol + D-Chiro blend)
- Omega-3 fatty acids
- Magnesium
- Vitamin D
- Zinc
- NAC (N-acetyl cysteine). Always consult a healthcare provider before starting supplements.
Hormone Testing Options for PCOS
Testing can help uncover the root cause of your symptoms. At One Nutrition Group, we may recommend:
- Blood work: fasting insulin, glucose, HbA1c, testosterone, DHEA, LH/FSH
- DUTCH testing for deeper insight into cortisol and sex hormone patterns
- Micronutrient testing to assess deficiencies. Testing helps remove the guesswork and ensures your nutrition plan is tailored to you.
