NIDDK LISTENING SESSION ON INGESTIVE BEHAVIORS AND OBESITY Chair/Organizer: Susan Yanovski Virtual Room 1 In an effort to engage with the research community in multiple venues, NIDDK is convening several listening sessions in conjunction with national meetings, in which NIH program staff are reaching out to investigators to solicit input and ideas for ways to accelerate progress in obesity research. We want to have an open process with broad outreach to scientists at all career levels in an effort to identify exciting research opportunities, as well as obstacles to advances in basic and clinical research and to career development and progression. Join Drs. Susan Yanovski, Co-Director of NIDDK's Office of Obesity Research, and Brad Cooke, Director of NIDDK's Neurobiology of Obesity Program, at this interactive session to share your thoughts on the following questions: - What are the highest priority fundamental/basic knowledge gaps related to ingestive behaviors and obesity? - What is the highest priority clinical and/or translational research needed to advance prevention and treatment of obesity? - What tools, methods, or technologies would facilitate your research? - What are the biggest hindrances to your research career? - What should NIH/NIDDK be doing more (or less) of to make progress in prevention and treatment of obesity?
