If you were to go running there’s a good chance you’ll be yearning for an apple instead of a doughnut afterwards, suggests a recent brain imaging study, and that may be because your brain is pushing you towards water.

The study was small — 15 lean men — but it may help explain how exercise relates to hunger and overall health. It was published in the American Journal of Clinical Nutrition.

Research also suggests a host of perks we get from being active, from mental well being to heart health. And it can be fun.
So how do scientists and dietitians get their 30 minutes? At our research conference in November, we found out:
Are you expecting a season of holiday parties, special treats, being too busy to exercise and feeling extra stress? At our latest tweetchat we talked strategies for powering through those and other Holiday Hangups – health stoppers that can derail our usual habits that help us stay healthy, keep our weight in check, and lower risk for cancer.
