What Insulin Actually Does

Insulin's primary job is to lift glucose out of the bloodstream and move it into cells for energy. But when someone eats more sugar and carbohydrates than their cells can store—especially late at night—insulin keeps working. It packs excess sugar into the liver, then into fat cells.

What if the first signs of insulin resistance are already visible on your body?

Dr Annette Bosworth, also known as Dr Boz, is a physician and author whose work focuses on metabolic health, insulin resistance and ketogenic nutrition.

In this moment, Dr Boz explains how chronically high insulin can quietly affect the body long before many people recognise there’s a problem.
