I just posted a narrated Powerpoint version of my talk "Why Do We Overeat? A Neurobiological Perspective" to YouTube. Here's the abstract:
In the United States, the "obesity epidemic" has paralleled a gradual increase in daily calorie intake. Why do we eat more than we used to, and more than we need to remain lean-- despite negative consequences? This talk reviews the neurobiology of eating behavior, recent changes in the US food system, and why the brain's hardware may not be up to the task of constructively navigating the modern food environment.
This is the same talk I gave at the University of Virginia this January. I had a number of people request it, so here it is:
This is one of my favorite talks, and it was very well received at UVA. If you find it informative, please share it!
