Episode 88: Dr. Kevin Hall of the NIH is on to discuss the recent carb restriction vs. fat restriction study, issues surrounding weigh regain, homeostatic regulation of weight and the physiology of fat loss.

Guest Bio

Kevin Hall, PhD

Dr. Hall’s laboratory investigates how metabolism and body composition adapt in response to a variety of interventions. They perform experiments in both humans and rodents to better understand the complex mechanisms regulating macronutrient metabolism, body composition, and energy expenditure. A unique aspect of the laboratory involves the development of mathematical models to quantitatively describe, explain, integrate, and predict our experimental results.

In this episode we discuss:

• The recent carbohydrate restriction vs. fat restriction study
• Homeostatic mechanisms that underpin calorie intake and expenditure
• Taking an integrated view of energy balance, hormones and external food cues
• Using mathematical models to predict calorie intake and/or bodyweight changes
• The future of obesity research
