This actually was a surprise for me and I think it also goes against conventional wisdom.
... the intense exercise will ultimately help you to eat less, not more.
In a study conducted at the University of Western Australia, high intensity interval training or HIIT was found to suppress the hunger-stimulating hormone ghrelin. Having high levels of ghrelin makes you crave food – especially the high-calorie kind. In fact, excess ghrelin is a focus of several obesity studies.
Hmmm... Interesting article! But when I do heavy weights or high intensity cardio like cardio kick boxing... I get hungry after the workouts! So, I say... I earn to eat some good food!
