Okay Weighthackers, here’s some more good news about exercise: Not only does it help you lose weight and tone up (i.e. look better), it can make you less hungry too. This new finding comes from a study done last year at the University of Wyoming, which showed that exercise actually changes the way your body reacts to food.
Here’s how it works. Normally a hormone called ghrelin is one of the things in your body that stimulates hunger. When you workout, your body actually makes more ghrelin, which should in turn make you hungrier.
But the researchers up in Wyoming found that exercise also stimulates the production of hormones that make you feel satiated. According to The New York Times:
These hormones, only recently discovered and still not well understood, tell the body that it has taken in enough fuel; it can stop eating. The augmented levels of the satiety hormones, the authors write, “muted” the message from ghrelin.
But wait, the news gets better. The Times said another study done in December confirms that moderate exercise helps regulate hunger. “It found that after 12 weeks, formerly sedentary, overweight men and women began recognizing, without consciously knowing it, that they should not overeat.”
This jibes (yes, I used the word jibes) with my own experience, where I found that after I started being more active each day, my hunger went down, as did the amount of food I ate when I was hungry. The only trick though is that it takes 3 months of steady effort for the effect to kick in. So, get started!
