Insulin Controls Fat vs Sugar Burning

Your body physically cannot burn fat and sugar at the same time. It is a biological

standoff known as the Randle Cycle. Think of your metabolism like a one-lane highway where glucose

and fat are fighting to get through, but they block each other. The traffic cop

deciding who wins is insulin. When insulin is high, it forces your cells

to run on sugar and completely locks the doors to your fat stores. You literally cannot

burn body fat when insulin is present. To switch modes and become a fat-burning machine,

you have to drop the insulin. You don't just are what you eat, you burn what you

eat.
