If you’ve recently been diagnosed with PMOS (previously known as PCOS), you’ve probably heard the term insulin resistance being thrown around. Today, we’re breaking down what it means and the role carbohydrates and the glycaemic index play.
Insulin resistance occurs when the cells in our body don’t respond properly to insulin. Insulin is a hormone produced by the pancreas that helps move glucose from the food we eat into our cells for energy. When insulin resistance is present, the body struggles to “open the door” to let glucose in, meaning glucose stays in the bloodstream instead of being stored or used.
Carbohydrates are our body’s main fuel source, and when we eat them, they’re broken down into glucose. If you have PMOS, it’s important not to cut out carbohydrates, instead, be strategic about the types you choose and how you spread them throughout the day.
Glycaemic Index (GI) is a measure of how quickly or slowly a carbohydrate food is digested and raises blood sugar levels.
- High‑GI foods cause a fast spike in blood glucose.
- Low‑GI foods raise blood glucose more gradually and are the best options to include regularly.
Think wholegrain breads, pasta, brown rice, oats, legumes and dairy.
To sum it all up: if you have PMOS and insulin resistance, choosing low‑GI carbohydrates and spreading them evenly across the day can help support your pancreas without overwhelming it with large amounts of glucose at once.
