Binge eating and weight control: the role of experiential avoidance.

Lillis et al. (2011) looked at old data from a one-day ACT workshop for adults who wanted to lose weight.

They asked: does lowering experiential avoidance (the urge to run from tough thoughts and urges) lead to less binge eating and then to actual weight loss?

Yes. When people dropped their avoidance, binge episodes fell.

Less binge eating then predicted pounds lost.

The chain was: ACT skills → lower avoidance → fewer binges → lighter scale.

Patton et al. (2020) saw the same chain in a self-help workbook for anxiety. Clients who practiced the skills daily got the same mediation path, showing the idea holds outside a live workshop.

Lappalainen et al. (2007) found the same link earlier: trainee therapists using ACT saw acceptance rise and symptoms fall. Their study used full therapy sessions, so Jason’s 1-day format gives a faster, cheaper route to the same process.

Sievers et al. (2020) stretched the model to hair-pulling. A 10-session ACT package cut pulling by first raising psychological flexibility, again showing the core process travels across very different problem behaviors.

You can target avoidance first, no matter the behavior. A brief ACT exercise—values card sort, urge surfing, or simple willingness practice—may cut binge eating, pulling, or anxiety without weeks of sessions. Try opening your next feeding or self-care protocol with one ACT micro-drill and track if the behavior drops next.
