New Research Helps Explain How Exercise Burns Fat

Certain hormones in your body work constantly to regulate things like hunger, stress, mood and more. Scientists now know there is also a hormone that burns fat when you exercise.

This isn’t a newly discovered hormone. We just know more about the role it plays in fat loss, thanks to a study published in the American Journal of Physiology – Endocrinology and Metabolism. The hormone irisin is responsible for increased fat burning.

To better understand why, all you really need to know is that your body has two types of fat. These are white fat and brown fat. White fat is stored fat, while brown fat is the “fuel” that burns calories. When you exercise, you burn off brown fat. Irisin is in a way responsible for making sure more of your stored white fat gets converted into brown fat, which you then “burn off.”

Basically, when you work out, irisin sends a message to some genes and proteins. Those then change white fat into brown fat, which gets used as energy when you exercise. The short version: exercise consistently, and you will burn more fat because you have a hormone that regulates it. All you have to do is show up and put in the effort. You will see results in time.


MP’s Take: It’s helpful to know why exercising gives you the results it does. Once you have a better idea of why your body is changing the more consistent your workouts are, you might become more motivated. You can come to expect certain results with certain training methods, which builds anticipation. If you can think to yourself, “I’m producing results right now – I just can’t see them yet,” maybe that will make a huge difference for you. Anything to help keep you motivated and encourage you to get out there and tough it out, even when you feel stuck in a rut or don’t want to. Results are gradual, but noticeable, eventually.
