#TomorrowsDiscoveries: Preventing Obesity – Dr. Susan Carnell

>>Obesity affects over
a third of adults and 17% of children in the U.S. Being overweight can
substantially increase the risk of developing serious medical conditions, including heart disease and diabetes. I’m Susan Carnell, and
I run the Appetite Lab at Johns Hopkins, where we
ask the central question, why do some people become
obese while others don’t? To find the answers, we
work with various groups, including children and their parents and patients having weight loss surgery. And we use a mixture of
different techniques, like behavioral experiments
and biological measurements. Using brain imaging, for
example, we found that teenagers with a family history of
obesity showed less activity in response to food cues in
certain parts of the brain. This suggests that
strengthening this appetite regulation system or finding
ways to limit exposure to high calorie food cues may be helpful. All these studies take us closer to the ultimate goal of my research, to treat or prevent
obesity more effectively. (bright music)
