Living with Polycystic Ovary Syndrome (PCOS) can feel like a constant battle with your body, but your diet plays a crucial role in managing symptoms and improving your overall health.

Among various dietary approaches, following a low glycemic diet emerges as a beacon of hope for many struggling with this condition. This blog post delves into the transformative power of a low glycemic diet for individuals with PCOS, shedding light on how mindful eating can not only alleviate symptoms but also pave the way for a healthier, more balanced life.

In this blog post, we’re going to break down the PCOS and insulin resistance relationship and explain the benefits of a low GI diet for PCOS. We'll explore how such a diet not only supports weight management and reduces the risk of developing diabetes but also balances hormones and improves fertility. Whether you're newly diagnosed or have been navigating the complexities of PCOS for years, understanding the impact of a low glycemic diet can be a game-changer in your journey toward wellness.

So, let's dive into how making thoughtful choices about what we eat can transform your relationship with PCOS and lead you toward a healthier future.

What is PCOS

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder affecting 5% to 10% of women of reproductive age worldwide. 

It’s a condition characterized by cysts on the ovaries, irregular periods, hormonal imbalance, and an increased risk of infertility. But despite its name, it’s one that is also closely tied to insulin resistance as it can develop in response to a substantial amount of weight gain.

Let’s break down the PCOS and insulin resistance connection:

PCOS & Insulin Resistance 

In otherwise healthy individuals, insulin rises briefly after eating, stimulating the body to take up glucose and convert it to energy. 

When one has insulin resistance, though, the pancreas is creating more insulin to overcompensate for the rise in blood sugar levels. And as insulin levels continue to build, it can lead to inflammation, weight gain, and type 2 diabetes. 

While the exact cause of PCOS is unknown, what is certain is that women with PCOS are intrinsically insulin resistant. 

In other words, insulin resistance isn’t a symptom but rather a key feature of PCOS. 

For example, research shows that the skeletal muscle of overweight women with PCOS is deeply embedded with defects in glucose transport and insulin signaling.

Additionally, it’s the high insulin levels that harm ovulation and cause the ovaries to make excess testosterone.

The Low GI solution for PCOS

Because low glycemic foods are slow to break down in the body, they keep you full longer and don’t raise your insulin levels like foods higher on the GI scale do.

That’s what makes a low GI diet for PCOS so beneficial for managing and treating symptoms as high insulin levels are a feature of PCOS, and eating low GI foods will help you manage your weight. 

Low GI research

A study placed premenopausal women with PCOS on a low glycemic diet and a macronutrient matched diet to compare their insulin sensitivity. They were followed for 12 months (or until they had a weight loss of 7%).

The results showed those who followed a low GI diet had improved their insulin resistance than those who followed the alternative diet. 

Another study looked at the ovulation cycles of women with PCOS for three months while following either a low glycemic diet or a normal diet and found that those who followed a low GI diet had improved their cycles.

Low GI diet for PCOS

Losing weight is one of the most effective ways you can regulate your menstrual cycle and improve your symptoms of PCOS, and a low glycemic diet can do just that. 

A low GI diet requires that you use the glycemic index scale to keep your blood sugar levels in check. This means the majority of your diet should consist of foods that have a glycemic index of 55 or less, and a moderate amount should have a GI of 56 to 69.

A low GI diet for PCOS includes but is not limited to:

• Non-starchy vegetables such as cauliflower, spinach, and sweet potatoes
  • Benefits: These vegetables are high in fiber, vitamins, and minerals but low in calories and carbohydrates, which can help manage weight and reduce insulin resistance. Insulin resistance is a common concern in PCOS, and managing it can help regulate menstrual cycles and improve fertility.
    
• Fruits such as berries, grapefruit, and apples
  • Benefits: These fruits have a low to moderate glycemic index, meaning they have a lesser impact on blood sugar levels. Consuming these fruits can help satisfy sweet cravings without causing significant blood sugar spikes, which is crucial for managing PCOS symptoms. The antioxidants and phytonutrients in these fruits also support overall health and can reduce inflammation.
    
• Whole grains such as steel-cut oats, millet, and quinoa
  • Benefits: Whole grains are a great source of complex carbohydrates and fiber, which promote slow and steady digestion and absorption, helping to keep blood sugar levels stable. This stability is key in managing PCOS, as it can help reduce insulin levels and improve symptoms such as weight gain and irregular periods. Additionally, these grains can contribute to a feeling of fullness, aiding in weight management.
    
• Lean Proteins such as eggs, salmon, and turkey
  • Benefits: Lean proteins are essential for building and repairing tissues and maintaining muscle mass, which can be beneficial for weight management—a common challenge for those with PCOS. Protein-rich foods also have minimal impact on blood sugar levels, supporting steady energy levels and reducing hunger. Foods like salmon, which contain omega-3 fatty acids, can also reduce inflammation and improve the lipid profiles often associated with PCOS.
    
• Healthy fats such as olive oil, avocados, and nuts
  • Benefits: Healthy fats are crucial for hormone balance, which is particularly important for individuals with PCOS. They can improve insulin sensitivity, reduce inflammation, and support weight management. Foods like avocados and nuts also provide fiber and antioxidants, contributing to overall nutritional balance and satiety, which can help prevent overeating.

The benefits of low GI

If you have PCOS, there are several benefits to following a low glycemic diet such as:

• Weight loss promotion — Research shows weight gain to be associated with PCOS. Moreover, eating foods high on the GI scale causes insulin and blood sugar levels to rise and fall. This makes you vulnerable to overeating and weight gain.
   

Low GI foods have the opposite effect. They keep you full longer and give you fewer food cravings which help you lose weight in a sustainable way. 

• Diabetes prevention — When you have PCOS, more insulin is traveling through your body, putting you at a higher risk of developing diabetes. Thus, eating low GI foods will reduce your risk of developing diabetes significantly.
   
• Hormone balance — Eating an excess of high GI foods is more likely to cause an imbalance of your hormones. 
  
  

"I am so excited to learn about low glycemic foods. I have been eating this way now for a couple weeks and I don’t have crashes, I’ve even lost a pound and  a half And I don’t ache from the inflammation from sugar. Plus, the cravings for all the bad sugar are so much less! I’m really enjoying learning all about this way of living" -Julie

Foods to avoid

Foods high on the glycemic index scale should be avoided as much as possible. This means foods that have a GI of 70 or higher. These include:

• Refined carbohydrates, i.e., “empty calorie” foods or foods that have been processed.
  
  • Why to Avoid: Often high in unhealthy fats, added sugars, and sodium, processed foods can contribute to weight gain, inflammation, and insulin resistance. They're also usually low in fiber, which is essential for blood sugar control and weight management in PCOS.
    
    
• White bread, rice, pasta; pastries, and potatoes 
  • Why to Avoid: Refined carbs can cause rapid spikes in blood sugar and insulin levels, exacerbating insulin resistance, which is a common issue in women with PCOS. High insulin levels can lead to increased androgen production, worsening symptoms like acne, hair growth, and irregular periods.
    
    
• Sugary beverages such as fruit juice and soda 
  • Why to Avoid: High in added sugars, these drinks can lead to weight gain and increased insulin levels, both of which can worsen PCOS symptoms. They offer little to no nutritional value and can disrupt your hormonal balance.
    
    
• Fried foods 
  
  • Why to Avoid: Fried foods have a high GI can cause rapid increases in blood sugar and insulin levels. Managing blood sugar levels is crucial for women with PCOS to reduce the risk of developing diabetes and to help manage symptoms.
