Harmful effects of excess weight

How does obesity cause diabetes?

There is a strong connection between obesity and risk of developing diabetes. More than 80% people with type 2 diabetes are overweight.1

This is because excess fat leads to low production of insulin by the body (Insulin is a chemical which breaks down sugar in our food). Excess fat also releases some other chemicals that act on the cells of the body and make them less responsive to insulin. As these cells become resistant to insulin, they do not utilize sugar in the blood and it starts accumulating, leading to high blood sugar levels. This type of diabetes is called type 2 diabetes.2
