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 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 to 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.

Precise measurement of body composition offers a powerful window into health and disease. This session explores the cutting-edge methodologies clinicians and scientists use to quantify body components—from fat mass and lean tissue to cellular and molecular markers. With longitudinal assessment, these tools enable tracking of patient outcomes, guiding diagnosis, prevention, and treatment strategies across a range of clinical conditions. Dr. Dympna Gallagher of Columbia University will dive into how advancements in body composition analysis—paired with energy expenditure measurements, brain imaging, and behavioral assessments—are reshaping our understanding of obesity, metabolism, and the efficacy of nutritional, pharmacologic, and lifestyle interventions. This session is especially relevant for physicians and researchers working at the intersection of clinical care and translational science who want to stay at the forefront of personalized obesity care and precision medicine.

The efficacy of CNS acting anti-obesity drugs draws heightened attention to defining the brain cells and circuits that mediate food consumption and its inhibition. While hypothalamic involvement has been emphasized historically, significant research highlights roles for contributions from neurons in other brain regions. This talk focuses on roles for hindbrain neurons in controlling the termination and initiation of meals as well as in the visceral malaise that accompanies drug treatments.

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.

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.

While diet recommendations have seemed to go back and forth in weight loss trials in terms of carbohydrates and fats, high protein recommendations appear to have been consistently recommended. With a unique combination of evidence-based science and humor, Professor Gardner will share his perspective across multiple weight loss diet trials that despite a range of designs and protein recommendations, protein almost always ends up at 20% of calories – and he can’t explain why.
