Insulin resistance: the missing link behind stubborn symptoms
Many women come to nutrition coaching feeling confused and frustrated. They are eating well, exercising regularly, and doing everything they have been told should work, yet their body still feels stuck.
Weight does not shift.
Energy crashes mid afternoon.
Cravings feel out of control.
Periods are irregular or painful.
Skin issues persist despite a clean diet.
One underlying driver I see again and again is insulin resistance.
What insulin actually does in the body
Insulin is a hormone released by the pancreas that helps move glucose from the bloodstream into your cells, where it can be used for energy.
Every time you eat carbohydrates, and to a lesser extent protein, insulin is released. This is a normal and necessary process. Problems arise when the body stops responding efficiently to insulin.
When cells become resistant to insulin, glucose struggles to enter the cells. The pancreas responds by producing more insulin to compensate. Over time, insulin levels remain chronically elevated.
This state is known as insulin resistance.
Why insulin resistance matters for women’s health
Insulin is not just a blood sugar hormone. It has a powerful influence on other hormones in the body.
Chronically elevated insulin can:
Increase fat storage, particularly around the abdomen
Disrupt ovulation and menstrual regularity
Worsen symptoms of PCOS
Drive cravings and appetite dysregulation
Increase inflammation in the body
This is why many women feel like their body is working against them, even when their habits appear healthy on the surface.
Signs of insulin resistance
Insulin resistance does not always show up clearly on standard blood tests. Many women are told their results are normal while still experiencing symptoms.
Common signs include:
Strong cravings for sugar or carbohydrates
Feeling shaky or irritable when meals are delayed
Energy crashes after meals
Difficulty losing weight despite consistent effort
PCOS or a history of irregular cycles
You do not need to have diabetes to be insulin resistant. In fact, insulin resistance often develops years before blood glucose markers become abnormal.
What drives insulin resistance
Insulin resistance is not caused by one single factor. It is usually the result of cumulative stress on the body.
Key contributors include:
Chronic stress and elevated cortisol
Poor sleep or inconsistent sleep patterns
Highly processed diets low in fibre and protein
Excessive endurance cardio without adequate recovery
Long periods of undereating
This is why extreme dieting and pushing harder in the gym often backfire.
Supporting insulin sensitivity in a sustainable way
Improving insulin sensitivity is not about eating less or cutting out entire food groups.
It is about creating an internal environment where the body feels safe enough to respond properly to insulin again.
This includes:
Eating balanced meals with adequate protein, fibre and healthy fats
Strength training to increase muscle mass, which improves glucose uptake
Managing stress and nervous system load
Prioritising sleep and recovery
Eating enough overall calories to support hormonal health
When insulin sensitivity improves, many women notice more stable energy, reduced cravings, improved cycles and body composition changes that finally feel sustainable.
Insulin resistance is not a personal failure. It is a physiological response to long term stress on the system. And the good news is that it is highly reversible with the right support.
