A daily gratitude listing intervention is associated with selection of smaller food portion sizes.
Trial report in Appetite, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivePerceived deprivation and lower social status compared to others is associated with reduced sensations of fullness, selection of larger food portion sizes, and greater energy intake. Yet, it is unknown whether opposing experiences of gratitude, or appreciation of what one has, is associated with motivation to consume less energy. We tested whether a daily gratitude listing intervention leads to reduced energy intake and selection of smaller portion sizes.
methodsYoung adults from a Singaporean university (N = 162; Mean Age = 21.59 ± 1.89; 98 female) were randomly assigned to either a daily gratitude listing intervention or daily event listing control condition for 2 weeks. Free-living energy intake was measured with food journals during the intervention period, and desired portion sizes for many foods were measured at baseline and post-intervention sessions using a virtual portion selection task.
resultsThere was no effect of the intervention on free-living energy intake, but those in the gratitude condition selected smaller portion sizes post-intervention compared to baseline; no change in portion size was observed for the control condition. The intervention reduced portion sizes for high energy-dense foods, but not lower energy-dense foods. Reduced appetite between the baseline and post-intervention sessions mediated this effect of the intervention on smaller portion sizes.
conclusionsWhile perceived deprivation may stimulate appetite and the drive to eat, gratitude for what one has may promote satiety and intentions to eat less. Gratitude interventions may promote intentions to eat less, although effects on food intake require further investigation.
