low gi foods for pcos

Polycystic Ovary Syndrome (PCOS) affects many women worldwide, often leading to weight gain and difficulties in losing those extra pounds. 

The key factor contributing to weight gain in PCOS is high Insulin levels, which trigger fat storage in the body. 

It becomes crucial to focus on lowering Insulin levels to tackle this issue. 

One effective dietary approach that has shown promise in managing PCOS symptoms and promoting weight loss is adopting a low glycemic index (GI) diet. 

A 2007 study by American Medical Association showed that 95% of women who followed a low GI diet for PCOS had regular periods. 

This article will tell the benefits of low GI foods for PCOS and provide practical guidance for incorporating them into your diet.

Approximately 80% of women with PCOS struggle with weight issues due to high Insulin levels, which disrupt the body’s ability to break down stored fat. 

When Insulin levels are elevated, the body remains in fat storage mode, making weight loss challenging. 

Lowering Insulin levels through diet, exercise, and medications like Metformin and supplements such as Ovasitol is crucial for achieving weight loss and managing PCOS symptoms effectively.

Good to know:
Metformin is a medication commonly used for managing PCOS and type 2 Diabetes. It improves Insulin sensitivity, helps control blood sugar levels, and may contribute to modest weight loss.

Research supporting low GI foods for PCOS

Several studies have shown that individuals with high Insulin levels, particularly those with PCOS, benefit most from a low GI diet. 

It helps with weight loss and improves Insulin sensitivity. 

Fluctuating insulin levels can have adverse effects on your health. High insulin levels, as seen in conditions like PCOS, can lead to insulin resistance, weight gain, and an increased risk of developing diabetes.

A notable study on women with PCOS compared a low GI diet with a high-fiber diet containing whole grains.

The results demonstrated that those following the low GI diet experienced a three-fold more significant improvement in Insulin levels. 

Furthermore, women combining a low GI diet with Metformin exhibited the most significant enhancements in Insulin sensitivity. 

Another study published in the Journal of the American Medical Association found that individuals with high Insulin levels lost significantly more weight on a low GI diet than on a low-fat diet.

The concept of the Glycemic Index (GI)

The glycemic index (GI) is a scale that ranks carbohydrates and how they affect blood sugar levels after consumption. 

High GI foods can cause rapid increases in Insulin levels and blood sugar, while low GI foods have a slower, steadier impact. 

Incorporating low GI foods into your diet helps regulate blood sugar levels, manage Insulin resistance, and promote weight loss.

Identifying Low GI foods

To adopt a low GI diet for PCOS, focus on consuming foods with a glycemic index of 55 or less. 

Here are some foods having low GI foods for PCOS:

Non-starchy vegetables such as cauliflower, spinach, broccoli, asparagus, and sweet potatoes are rich in nutrients and fiber. 

Low GI values make them ideal choices for a PCOS-friendly diet.


Opt for fruits like berries, grapefruit, apples, pears, and cherries. 

These fruits offer antioxidants, vitamins, and minerals while having low GI values.

Whole grains

Choose whole grains like steel-cut oats, quinoa, brown rice, millet, and whole wheat bread. 

These grains provide sustained energy and increased fiber intake, helping to stabilize blood sugar levels.

Lean proteins

Incorporate lean proteins such as eggs, salmon, turkey, chicken breast, tofu, and legumes. 

These protein sources help meet your nutritional needs without spiking blood sugar levels.

Healthy fats

Embrace sources of healthy fats like olive oil, avocados, nuts, and seeds.

These fats provide satiety, support hormone balance, and contribute to a balanced and nutritious diet.

The benefits of low GI foods for PCOS

Adopting a low GI diet offers various advantages for women with PCOS, including:

Weight loss promotion

High Insulin levels and blood sugar fluctuations associated with PCOS contribute to weight gain. 

By incorporating low GI foods, you can stay fuller for longer, reduce food cravings, and achieve sustainable weight loss.

Diabetes prevention

PCOS individuals have a higher risk of developing diabetes due to Insulin resistance.

You can significantly reduce this risk and maintain stable blood sugar levels by consuming low GI foods.

Hormone balance

Excessive consumption of high GI foods can disrupt hormonal balance and exacerbate PCOS symptoms

Opting for low GI foods helps maintain stable hormone levels and alleviate associated symptoms.

Foods to avoid

Minimizing or eliminating high GI foods is crucial to follow a low GI diet for PCOS effectively. 

Avoid foods with a GI of 70 or higher. 

By minimizing or eliminating the high GI foods from your diet, you can better manage PCOS symptoms and support weight loss efforts. 

Here are some examples of foods to avoid:

  • Refined carbohydrates
  • Pastries and baked goods
  • Sugary beverages
  • Fried foods
  • High-sugar fruits
