Calories, Carbs, or Quality? What Matters Most for Body Weight

Calories, Carbs, or Quality? What Matters Most for Body Weight

DATE: WEDNESDAY, JUNE 24, 2020

TIME: 8:00 AM PDT | 11:00 AM EDT

Kevin Hall, PhD discusses the physiology of body weight regulation and how dietary factors like amount of carbs, fat and “ultra-processed” foods affect human body weight.

Eating fat makes you fat. No, eating carbs makes you fat. Actually, it’s a simple equation relating calories in and calories out. Such endless debates about putative dietary culprits or cures for obesity have led to widespread public confusion and mistrust in nutrition science. But what is the truth?

During this webinar, Dr. Kevin Hall will discuss the physiology of body weight regulation and how we adapt to various changes in diet, including the amount of calories, carbs versus fat, as well as differences in diet quality varying in the amounts of “ultra-processed” foods. Understanding the dynamics of human body weight change has important consequences for conditions such as obesity, diabetes, cardiovascular disease, starvation, and wasting syndromes such as anorexia nervosa and cancer cachexia.

Key discussion topics include:

  • Understand how body weight is regulated as part of a negative feedback control system
  • Understand how the body responds to diets with wide variation in their ratio of carbohydrate to fat
  • Understand how the body responds to diets varying in quality as determined by their amount of ultra-processed foods

About the Presenter:

Kevin Hall, PhD is the Integrative Physiology Section Chief at NIDDK-NIH.  His laboratory investigates how metabolism and the brain adapt in response to a variety of interventions to diet and physical activity. His team conducts experiments in both humans and rodents to better understand the complex mechanisms regulating macronutrient metabolism, body composition and energy expenditure. Uniquely, his research also involves the development of mathematical models to quantitatively describe, explain, integrate, and predict experimental results. Overall, Dr. Hall’s research aims to improve our understanding of body weight regulation and develop practical tools for research and clinical use.
