If there was a hormone in your body whose chief job was to make you feel hungry, most of us probably wouldn't be too keen on it. (I don't know about you, but having a healthy appetite has never been a problem for me.) But if there was a hormone that decreased our appetites, we'd order buckets of it! Well, let me introduce you to some hormones that do just those things: the hunger hormones, leptin and ghrelin. Leptin is a hormone, made by fat cells, that decreases your appetite. Ghrelin is a hormone that increases appetite, and also plays a role in body weight. Levels of leptin -- the appetite suppressor -- are lower when you're thin and higher when you're fat.
