Charles Duhigg Lost 45 Lbs on a GLP-1 | Why Food Noise Vanishes

Charles Duhigg
Show Notes

Charles Duhigg discusses his personal experience losing 45 lbs on a GLP-1, exploring how these drugs not only suppress appetite but also quiet the obsessive 'food noise' that drives compulsive eating. He draws on his expertise in habit formation to argue that the real power of GLP-1s lies in the temporary window they create: a chance to rewire habit loops, cultivate keystone habits, and solidify a new identity before tapering off the medication. The conversation covers the neuroscience of cravings, the difference between habits and addictions, and why sustainable weight loss requires more than just a prescription.
