Carbs and PCOS: 3 Mistakes to Avoid (and What to Do Instead)


If you live with PCOS, chances are you’ve been told (or Googled) that carbs are the enemy. Maybe you’ve heard “cut carbs to lose weight” or “go low-carb if you have PCOS.”

But here’s the truth: carbohydrates are not the villain. In fact, cutting them out altogether often leads to exhaustion, cravings, mood swings, worsened symptoms and metabolic health. The key isn’t about eliminating carbs - it’s about understanding how to eat them in a way that supports your hormones, energy and long-term health.

In this post, I’ll break down the top three mistakes I see people with PCOS making when it comes to carbs, and what you can do instead. These are strategies I teach inside thePCOS Recovery Program


Mistake #1: Focusing on Carb Quantity Instead of Quality

It’s easy to get caught up in the numbers - counting grams of carbs and trying to stay under a certain amount. But this misses the bigger picture.

One of my clients used to cycle between very low-carb (30-40g/day) and moderate carb intake. She felt constantly fatigued, her cravings were uncontrollable, and her continuous glucose monitor showed huge blood sugar swings. Why? Because the carbs she was eating were mostly simple, ultra-processed options that spiked her blood sugar quickly.

What made the difference? Shifting the focus to fibre-rich, nutrient-dense carbs - like oats, buckwheat, lentils, beans and starchy vegetables. These provide steady energy, essential micronutrients, and help keep blood sugar stable.

👉 Instead of cutting carbs, add slower-digesting carbs. Swap white pasta for soba noodles, add lentils into your rice, or enjoy fruit with your breakfast. Nutrition by addition is far more effective than restriction.

Mistake #2: Ignoring Carbohydrate Timing

Many people with PCOS skip breakfast or eat very little during the day - then find themselves ravenous at dinner. This leads to big carb-heavy meals all at once, blood sugar crashes and intense cravings afterward.

Here’s why: when carbs are eaten in large amounts at once, blood sugar spikes rapidly. The body pumps out extra insulin, and for those with insulin resistance (up to 70% of people with PCOS), this cycle can worsen symptoms.

A better approach? Distribute carbs evenly throughout the day.

  • Add fruit or whole-grain toast to your morning eggs

  • Include sweet potato, beans, or quinoa with your lunch salad

  • Pair carbs with protein and fat for a balanced release of energy

This helps maintain stable blood sugar, improves insulin sensitivity, and keeps cravings manageable.

Mistake #3: Ignoring Your Individual Carb Tolerance

Here’s the thing: no two people with PCOS are the same. Your genetics, exercise patterns, other lifestyle factors, gut microbiome composition, medical history and more all influence how your body processes carbs.

Some people tolerate higher amounts of carbs with little impact on blood sugar, while others may notice more fluctuations. That’s why finding your unique carb tolerance is key.

Working with a registered dietitian can help you:

  • Assess your medical history and lab work

  • Analyze your diet and lifestyle for patterns and gaps 

  • Identify the carb sources and timing that work best for you

  • Make small, evidence-based adjustments over time

The goal is not perfection - it's building a foundation that supports your body’s needs long-term.

Your PCOS Carb Game Plan

To recap, here’s how to approach carbs with confidence:

  1. Focus on quality, not just quantity → Choose fibre-rich, minimally processed carbs.

  2. Distribute carbs evenly → Don’t skip breakfast, and aim for balanced meals.

Find your unique tolerance → Your needs are individual—work with a professional to fine-tune.
