Dr Jen Unwin, Dr. Rangan Chatterjee
Show Notes

Dr Jen Unwin, a clinical psychologist and food addiction researcher, explains why sugar and ultra-processed foods create genuine addictive patterns in vulnerable people—activating the same brain reward centers as nicotine and alcohol. She introduces the CRAVED self-assessment tool to identify problematic food relationships, discusses why willpower alone fails against modern food engineering, and provides practical strategies for regaining control through environmental design and cold turkey vs. moderation approaches.

•
Food Addiction Is Real and Neurobiologically Based
Sugar and ultra-processed foods activate the same reward centers in the brain as nicotine and alcohol, creating genuine addictive patterns in vulnerable people—not a matter of willpower or discipline.

Novel

•
The CRAVED Self-Assessment Tool
A six-point self-assessment framework for identifying whether your relationship with food is problematic—moving beyond vague 'cravings' to clinical recognition of addiction patterns.

Highlights

•
Hunter-Gatherer Neurobiology Unprepared for Modern Food Engineering
Our ancestors evolved without needing an 'off switch' for eating because natural foods are self-limiting; modern ultra-processed foods exploit this vulnerability by combining sugar, fat, salt, and dopamine-triggering engineering.

•
Environment Design as Addiction Treatment
Removing trigger foods from the home and restructuring your physical environment is often more effective than willpower—treating food addiction like addiction medicine would treat access to drugs.

Editorial

•
Cold Turkey vs. Moderation: Context-Dependent Approaches
For food addiction, cold turkey (complete avoidance) may be more effective than moderation for vulnerable people, similar to alcohol treatment—but the approach depends on individual addiction severity.
