Lesson 1 of 5 · PCOS and Hormone-Friendly Eating · about 7 minutes
Key takeaways
- PCOS is a common hormonal condition, and it looks different from one woman to the next.
- Many people with PCOS have insulin resistance, whatever their body size.
- Higher insulin can push the ovaries to make more androgens, which drives many symptoms.
- Everyday eating, movement and sleep habits can improve how your body handles insulin.
If you have been told you have polycystic ovary syndrome (PCOS), you may feel confused by the mixed messages online. Some posts say you must cut out whole food groups. Others promise a “cure” in 30 days. The truth is calmer and more hopeful: PCOS is a long-term condition, but there is a lot you can do with food and lifestyle to feel better.
In this first lesson, we will look at what PCOS is, why insulin matters so much, and how this course will help you build habits that last.
What is PCOS?
PCOS is one of the most common hormonal conditions in women of reproductive age. It affects how the ovaries work and is linked to the way your body uses insulin and makes hormones.
How it is diagnosed
The International PCOS Guideline (2023) uses a set of criteria. In adults, a diagnosis usually needs two of these three features, once other causes have been ruled out:
- Irregular or absent periods, which can mean you are not ovulating regularly.
- Signs of higher androgens (“male-type” hormones), such as extra facial or body hair, acne, or scalp hair thinning, or raised levels in a blood test.
- Polycystic ovaries on ultrasound, or a raised blood level of anti-Müllerian hormone (AMH) in adults.
The name is a little misleading. The “cysts” are actually small follicles (eggs that have not been released), not harmful cysts. You can have PCOS without them.
Common symptoms
Symptoms vary a lot. Some women mainly notice irregular periods. Others struggle most with skin, hair, mood, weight changes or difficulty getting pregnant. PCOS is also linked with a higher risk of type 2 diabetes, high cholesterol, sleep apnoea, anxiety and low mood, which is why long-term care matters.
Insulin resistance: the hidden driver
Insulin is a hormone made by your pancreas. After you eat, it helps move sugar (glucose) from your blood into your cells for energy. With insulin resistance, your cells do not respond to insulin as well as they should. To keep blood sugar steady, your body makes more insulin.
Why extra insulin matters in PCOS
Higher insulin levels can encourage the ovaries to produce more androgens. They can also lower a protein called SHBG, which normally “mops up” testosterone. The result is more active androgens in your blood, which can disrupt ovulation and cause acne or extra hair growth.
Insulin resistance is common in PCOS, and it is not only found in women living with a larger body. Slimmer women with PCOS can have it too. That is why this course focuses on habits that help insulin work better, rather than on the number on the scales.
Signs your body may be struggling with insulin
- Strong cravings or energy crashes a couple of hours after carb-heavy meals.
- Weight gain that settles mostly around the tummy.
- Dark, velvety patches of skin on the neck or underarms (acanthosis nigricans).
- Blood tests showing raised fasting glucose or HbA1c.
Only your doctor can confirm insulin resistance or prediabetes, so please do not self-diagnose from this list.
How lifestyle helps
The 2023 international guideline recommends healthy lifestyle habits for everyone with PCOS. There is no single “PCOS diet” that beats all others. Instead, the pattern of your eating, how active you are, and how well you sleep work together.
| Habit | How it can help |
|---|---|
| Balanced, high-fibre meals | Slower rise in blood sugar, so less insulin is needed |
| Regular movement | Muscles take up glucose more easily |
| Good sleep | Poor sleep makes insulin work less well the next day |
| Managing stress | Lower stress can ease cravings and support regular routines |
If you are living with a larger body, modest weight loss may improve periods and insulin for some women. But many benefits come from the habits themselves, even if your weight does not change much. Be kind to yourself: PCOS can make weight harder to shift, and that is not a failure of willpower.
What to expect from this course
Over the next four lessons you will learn how to build blood-sugar-friendly meals using everyday foods like dal, roti, rice, chickpeas and yoghurt; which nutrients matter for hormone health; how movement, sleep and stress fit in; and how to plan a simple week of PCOS-friendly eating. Each lesson ends with small, realistic steps.
Try this this week
- Write down your main PCOS symptoms and what bothers you most. This helps you set goals that matter to you.
- For three days, notice how you feel two to three hours after each meal: steady, hungry, tired or craving sweets.
- If you have not had recent blood tests, ask your doctor whether checking glucose, HbA1c and cholesterol is right for you.
Quick check
1. Do you need cysts on your ovaries to have PCOS?
No. A diagnosis can be made with irregular periods and signs of high androgens, even if ultrasound looks normal.
2. Can slim women with PCOS have insulin resistance?
Yes. Insulin resistance is common in PCOS across all body sizes.
3. Is there one special “PCOS diet” everyone must follow?
No. A balanced, high-fibre eating pattern you can stick to is what matters most.
