Fig. 1 — Study design: Adults (m, f, d) consuming a single meal in university cafeterias rated hunger and mood (and stress) using Likert scales before and after that meal with smartphones or mobile devices, in an app study (n₁ = 16,135, five-point scales, in dark blue) or in a more detailed web-based survey (omnivorous diet habits only, ten-point scales, n₂ = 173: free choice (in petrol), n₃ = 71: randomized choice (in turquoise)). Photos show exemplary pre- and post-meal plates for both meal categories (in petrol).
