Eyes Bigger Than Your Stomach?

Ghrelin isn't a diminutive mythical being dedicated to throwing monkey wrenches into the workings of daily human existence. It's a digestive hormone that may have the capacity to make food appear more desirable. At least that's what a new study published in the May edition of Cell Metabolism suggests.

Scientists have known for years that gut levels of ghrelin rise before eating and decline afterward. So they administered an infusion of this hormone to obese individuals, and noticed that they consumed significantly more calories from a free-choice buffet compared to people who were given a placebo. MRIs performed while subjects viewed images of food revealed that ghrelin influences networks in the brain associated with reward and motivation.

The Bigger Picture: So how can you defeat this gremlin known as ghrelin? You'll have to exercise some will power along with a sound diet strategy designed to restrict intake. Then there's regular physical exercise. It's a lot easier to resist temptation when you're feeling and looking that much better.
