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.
Physical activity is one factor that can influence our appetite, possibly by its role in altering our brain signals related to hunger and pleasure. This study focused on bouts of a high-intensity activity: running.
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.
In the study, the men first ran for an hour and then at a later day, they rested for an hour. For each trial, the men had easy access to water.
Ten minutes after they ran or rested, researchers scanned specific areas of the men’s brain as they looked at two dozen food images. In random order, they saw images of high-calorie foods — such as brownies, ice cream, pizza and fried chicken — and low calorie foods, including grapes, apples, lettuce, and carrots. (They also saw two dozen images of non-food items.) Continue reading
For many dieters, it’s not the losing weight that’s the hardest part, it’s the keeping it off. Now, just in time for those New Year resolutions, a new study finds that exercise and weighing yourself are among the key behavior strategies that may help sustain that weight loss for at least a decade.
The study, published in the American Journal of Preventive Medicine, draws from a select — but successful — group who were part of the National Weight Control Registry (NWCR) for 10 years. To enroll in the NWCR, you had to have lost at least 30 pounds and kept it off for over a year.
The findings are important because getting to and staying a healthy weight is one of the most important ways to reduce cancer risk. Overweight and obesity is a cause of seven cancers, along with increasing risk of type 2 diabetes and other chronic diseases.
For the study, almost 3,000 people answered questions about what weight-related behaviors they were doing one year after they enrolled in the NWCR. They reported their weight regularly throughout the decade. Continue reading
