Click Here! have been hearing for some time now that when it comes to weight loss, exercise is not king. Diet is paramount. I mean, the NY Times said it, so it must be true.1 To be fair, they cited many reputable studies in their report that seem to indicate exercise only goes so far in weight management. The amount you can burn in a single exercise session is easily erased by something as innocent as a second helping of dinner or a favorite sweet treat. Also for many, hunger increases after exercise and leads to overconsumption, thereby erasing or even worsening the calorie deficit they were striving for. I get it. I can see how exercise may not be the key piece in the giant puzzle of weight loss.

That being said, I have always had a nagging suspicion that exercise is more important than we think. We already know it helps for a host of issues other than weight loss, including mood/depression, cardiovascular health/blood pressure, blood glucose regulation, hormone balance, improved immune function, etc. People who exercise, on the whole, are healthier. Period. But I still had this feeling that given the right duration and intensity level, exercise has a key role in weight management.

Then this study popped up online2, giving us new insight into what might be going on with our metabolism when we exercise.

Researchers from Karolinska Institute in Sweden found mechanisms in mice by which exercise counteracted fat storage and decreased inflammation. A compound called kynurenic acid, induced via exercise, was the key.
