Quieting "Food Noise": How GLP-1s and Mindfulness Rewire the Default Mode Network (DMN) and Reward Circuits

Comprehensive Summary

This is a review of research going over "food noise" as a negative habit where your brain gets stuck planning for the future (foodwise) and looks into how 2 factors can stop it: GLP-1s and mindfulness. The author of this, Geoff Cook, reviewed research from 2010 to 2025 to mainly understand how these factors target the brain’s Default Mode Network (our wandering mind). The findings revealed that GLP-1s biologically reduce wanting (urge to eat), while mindfulness is more about the mind trained to ignore such urges. Cook concludes that these 2 treatments should be mashed together in a double-headed attack to reduce food noise better.

Outcomes and Implications

The research is important because it frames “food noise” as something like addiction, a cognitive issue, and not just a purely metabolic issue (remember our gut-brain connection). Clinically, this means that combining weight-loss drugs such as semaglutide and tirzepatide with mindfulness training could help patients experience faster and better results for weight loss. What’s more, even after the treatment regime has run its course, patients can maintain their reduced weight due to the past training. While the drugs may be commercially available today, doctors need more cold, hard evidence from long-term studies before this 2-in-1 approach can be a standard recommendation.
