EPISODE DESCRIPTION

In this Huberman Lab Essentials episode, I explain how the body senses and uses sugar, and why understanding those mechanisms can help reduce sugar cravings. I discuss different types of sugar and how they are processed by pathways in the gut and the brain to shape appetite and the desire for specific foods. I also share many science-based tools to help curb sugar cravings and support healthy blood sugar regulation.

EPISODE SUMMARY

In this episode of Huberman Lab, featuring Andrew Huberman, Dr. Andrew Huberman: How neuropod cells fuel sugar cravings explores science-based strategies to reduce sugar cravings and stabilize glucose Sugar appetite is regulated by hunger hormones (notably ghrelin), blood glucose dynamics, and insulin, reflecting the nervous system’s strong dependence on glucose fuel.
