Dr. Stephan Guyenet is a world renowned expert on the neuroscience of obesity and author of the New York Times bestseller, The Hungry Brain. In this episode of Momlight, Stephan sheds light on why so many of us struggle with overeating, weight gain, and obesity in the modern day. Stephan explains that the hardwired, brain-derived impulses that allowed us to thrive in an ancestral environment of food scarcity backfire and cause us to eat too much of the wrong foods in modern times. This is not a matter of low will power but rather, innate, non-conscious brain circuits that are "doing exactly what they are supposed to" but have now been placed in a new, mismatched environment where, for most of us, food excess rather than scarcity is the biggest challenge. Armed with this understanding, Stephan makes valuable recommendations on how we can maintain a healthy weight without it seeming like a constant uphill battle. If you or a loved one have ever struggled with losing weight and keeping it off, or if you're curious about the science of body weight regulation, you will find this conversation fascinating and thought-provoking.
