Food Service / Fast Food

Fast food discretionary spending declining as impulse eating decreases.

Declining

Why GLP-1 Matters Here

GLP-1 medications suppress what clinicians call food noise, the persistent background craving that drives unplanned eating occasions. Users report appetite reduction significant enough to skip meals entirely, with average calorie intake dropping 20 to 30 percent within months of starting medication.

Fast food revenue is structurally dependent on impulsive, high-frequency, large-portion visits. The category average ticket relies on upsizing and add-ons that GLP-1 users consistently report no longer wanting.

What the Data Shows

The Cornell difference-in-differences analysis of 150,000 households found an 8 percent spending decline within six months.

Analysis

The mechanism is direct: fewer unplanned visits, smaller orders per visit, reduced premium item attachment.
