Show food so good the viewer's stomach makes the purchase decision before their brain does.
Broken down by Jonas, a former Meta growth lead, from DoorDash's live ads in the Meta Ad LibraryDoorDash's highest-impression ads are 6-second close-ups of food. Cheese stretching, sauce dripping, steam rising. No voiceover, no branding until the last frame. The food imagery triggers a physiological response, literally, your mouth waters. By the time the DoorDash logo appears, the craving already exists and the viewer's phone is the fastest path to satisfaction. This is advertising at its most primal: stimulus → craving → action. The platform is irrelevant; the craving is everything.
Physiological triggers work for any product that satisfies an immediate physical desire, food delivery, beverages, comfort products, fragrance (show reactions), massage/spa. The format is cheap: close-up food photography or video with a good lens. The key is quality, low-resolution food photos trigger disgust, not craving. Invest in the photography. For restaurants or food brands: your best-selling dish, filmed at its most photogenic moment, is your highest-performing ad. No copy needed.
This breakdown is built from DoorDash's active ads, running for 5+ weeks at the time of writing, a signal the format is still working. See the current set for yourself in Meta's public Ad Library.
