The calculus of calories: food environments and body weight regulation
Increased prevalence of obesity isn’t due to a lack of willpower – body weight is biologically regulated in ways that make it difficult to lose weight and keep it off.

In this presentation Dr Kevin Hall will describe what we know about the physiology of body weight regulation as well as our emerging understanding of how food environment affects our biology.
