Background: An unhealthy diet is a major modifiable risk factor for chronic disease, and workplace environments may pose specific barriers to healthy eating. Methods: This single-arm, pre–post workplace intervention assessed short-term changes in perceived dietary barriers (primary outcome) and healthy eating intentions (secondary outcome) among school employees (n = 36; 83.3% women; mean age = 46.8 years). The 60 min participatory session integrated behavioral economics principles, practical nutrition exercises, and psychological strategies designed to enhance self-efficacy, optimism, and resilience. Results: The total perceived barrier score decreased significantly (Δ = −1 [IQR −2 to 0]; the paired Wilcoxon signed-rank test = −4.689, p < 0.001, r = −0.78). Post-intervention (T2), the proportion of participants reporting an intention to prepare healthy meals increased (McNemar’s test, p < 0.001; OR = 10.0, 95% CI 1.8–54.5). The session was rated as highly useful (mean = 8.3/10), and at the three-week follow-up (T3), 91.7% of participants reported maintaining at least one dietary change. Conclusions: Although limited by its single-arm design and short follow-up, this pilot study suggests that a brief, participatory behavioral intervention may be a feasible and acceptable approach to support healthier eating in the workplace.
