The function of insulin is to provide glucose to the body through the bloodstream. This glucose acts as energy for the cells and is created from the food we intake.

Therefore fasting creates insulin resistance. It happens when there is no food intake, due to which there is no production of glucose in the body. Since there is a shortage of glucose [blood sugar], the blood sugar levels drop. When the sugar levels are low, that results in low energy, which helps in losing fat.
