Researchers have a long history of fattening up mice to gain insight into the causes and consequences of weight gain in the human body. In one of the more recent studies of this kind, a team of IRP researchers found that that a high-fat diet consistently altered the collection of microbes residing in mice’s digestive tracts and that this diet-microbe combination might pre-dispose the mice – and, potentially, obese humans – to colon cancer by triggering certain changes in how genes behave.

Last month I moderated our annual retreat with the NIH Scientific Directors, those individuals tasked with leading their Institute or Center (IC)-based intramural research program. We were joined by many of the IC Clinical Directors. And this year we decided to do something a little different: listen to a series of talks about exciting, new IRP research.

Many scientists at the NIH used the metabolic chamber—a room constructed as a scientific instrument in which volunteers could live—to study how our bodies use air, food, and water under different conditions. Would you have volunteered for a study? Today's NIH Intramural investigators have even more advanced technologies to learn about energy expenditure's affects on obesity.

If you’ve ever skipped meals for a whole day or gone on a strict, low-calorie diet, you know just how powerful the feeling of hunger can be. Your stomach may growl and rumble, but, ultimately, it’s your brain that signals when to start eating—and when to stop. So, learning more about the brain’s complex role in controlling appetite is crucial to efforts to develop better ways of helping the millions of Americans afflicted with obesity.

Phoenix, Arizona, received its name from a British pioneer named Darrell Duppa. When he saw what was left of prehistoric settlements built by the Hohokam civilization thousands of years before his arrival, he knew that another great civilization would “rise from these ashes” just like the mythic bird. The desert city is today home to the Phoenix Epidemiology and Clinical Research Branch, one of six IRP research campuses.

The solution to obesity seems simple on the surface—fewer calories in, more calories out—but for those who have tried to lose weight, it's usually not an easy task, partly because weight is the product of many interrelated factors: environment, family history and genetics, behavior, metabolism, and others. 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.
