Gratitude has been associated with better physical health. Yet, surprisingly little research has experimentally investigated the capacity of gratitude to motivate individuals to eat more healthfully. In Study 1, among undergraduate students (N = 327) attempting to achieve a healthy eating goal, state gratitude following a writing activity significantly predicted healthier eating behavior 1 week later. In Study 2, across a 4-week intervention, 9th and 10th grade students (N = 1017) from four high schools were randomly assigned to either write weekly gratitude letters or to list their daily activities each week (control). Teens who expressed gratitude reported healthier eating behavior over time, relative to controls, and this effect was partially mediated by reductions in average negative affect across the intervention period. Thus, our findings suggest that gratitude-based interventions may facilitate improvements in healthy eating behavior in adolescents and young adults.
