Title: Studies of Overfeeding: Lessons for Body Weight Regulation
Date: Wed., June 18, 2025, 1-2 pm Eastern
CME Credits: 1
Price: Free to Members
Description: From the classic studies on “experimental weight gain” done by Ethan Sims, to Claude Bouchard’s studies of long-term overfeeding in identical twins, to the more recent studies George Bray and co-workers did on overfeeding diets that varied in macronutrient composition, studies using overfeeding as the experimental manipulation have expanded our understanding of how the body regulates weight. Because many of us treat people living with obesity with energy restriction, we have focused much of our attention on the adaptive responses to underfeeding and weight loss. Because weight is regulated, studies of the adaptive responses to overfeeding provide complementary insights that fill out the picture of how the body senses nutrient balance and responds with a wide variety of physiological responses that work to move the body back to a state of energy balance reflecting the homeorhesis of body weight, which for most is a trajectory of gradual weight gain through early and midlife.

Title: Nutrition is Everyone’s Business
Date: Wed., January 15, 2025, 1-2 pm Eastern
CME Credits: 1
Price: Free to Members
Description: Nutrition is everyone’s business. Why? Because we all eat. And the food we eat directly impacts our health and wellness. Nutrition connects food to health; it touches every cell and every system in our bodies, at every age and every stage of life. And the biology of nutrition is complex. We at the NIH Office of Nutrition Research appreciate this complexity and are dedicated to advancing nutrition research to promote health across the lifespan and to stimulating solution-focused research to address key elements of the domestic and global nutrition enterprise. Our areas of focus include: (1) enhancing precision in nutrition science; (2) nutrition across the lifespan (with particular attention on assessing and optimizing nutrition in each stage of the life course); and (3) nutrition and the environment.

Title: Assess and Treat Obesity as a Chronic Disease
Date: Wed., September 18, 2024, 1-2 pm Eastern
CME Credits: 1
Price: Free to Members
Description: Despite the wide recognition of obesity as a chronic disease, the clinical recommendations that guide the diagnosis of obesity and its management have not been aligned sufficiently with the clinical processes normally adopted for other chronic diseases. To stimulate the development and implementation of clinical guidelines for obesity more aligned with those already in place for other chronic diseases, the European Association for the Study of Obesity (EASO) proposed a new framework for the diagnosis, staging and management of obesity in adults.
