Obesity is a complicated problem and the solution may lie in a multi-prong approach. We look at what the science tells us about obesity, how various properties of foods can impact consumption, discuss the Carbohydrate Insulin Hypothesis and understand how the brain and body responds to an obesogenic environment.
Stephan J. Guyenet, PhD is a former neuroscience and obesity researcher and author of the book The Hungry Brain: Outsmarting the Instincts That Make Us Overeat, which was named one of the best books of 2017 by Publishers Weekly. His research has been cited more than 2,000 times by his scientific peers. His writing and speaking focus on the brain circuits that regulate eating behavior and body fatness, and how we can work with them to sustainably manage our waistlines.
