As happens with every new year, many people around the world woke up on January 1 committed to improving their health through eating well and exercising. These lifestyle changes have the potential to significantly improve the well-being of the 32 percent of American adults who are overweight and the 40 percent who are obese. Due to the staggering number of individuals struggling with obesity, as well as its serious health consequences, the condition has long been a main priority for researchers at the NIH. As a result of this focus, investigators have made significant strides in identifying biological signals that trigger hunger, understanding genetic influences that play a role in weight gain, and uncovering environmental and behavioral factors that influence obesity.

Investigators at the NIH Intramural Research Program (IRP) are studying all of those aspects and more to further understand the disease and better inform public health initiatives.
