Attempting Weight Loss Linked to Reduced Risk of Death

IRP Research Overturns Common Concerns About ‘Weight Cycling’

Tuesday, December 8, 2020

With 2021 less than a month away, many of the more than 200 million Americans who are overweight or obese are beginning to consider making weight loss their New Year’s resolutions — perhaps not for the first time. While trying to lose weight only to ultimately regain it may be disappointing, a new IRP study suggests that repeated attempts at weight loss significantly reduce a person’s risk of dying.

Extreme Obesity Shaves Years Off Life Expectancy

Four Questions with Dr. Cari Kitahara

Thursday, January 23, 2020

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.

Science by the Numbers: Modeling Complex Biological Processes

Monday, December 17, 2018

Science is a process of trial and error. Most successful research publications are preceded by at least a few false starts and perhaps weeks or even months of tinkering to get experiments to work. For IRP senior investigator Carson Chow, Ph.D., this process of testing and throwing out one potential solution after another is an essential part of his research, so much so that he may go through thousands of iterations before arriving at one that works. However, rather than test each approach himself, he leverages the IRP’s considerable computing power to considerably accelerate the process of sorting the wheat from the chaff.

Tracing the Neural Circuitry of Appetite

Wednesday, May 20, 2015

Reblogged from the NIH Director's Blog. Originally posted by Dr. Francis Collins, NIH Director, on May 5, 2015.

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.
