Meal pre-planning is considered a cost-effective behavioral strategy that can improve eating habits, reduce food waste and benefit food operators. This work aimed to offer new insights on the use of meal pre-ordering systems, in particular with regard to younger generations' booking habits and their evolution over time. Our data included observations from 946 students who visited a university canteen over the course of three years. We tried to address questions that were not previously explored in a real setting, namely we analyzed how widespread the use of pre-ordering can be, how much in advance and for how many days users plan their meals, whether there exists a compensation effect for those who order in advance and if increased familiarity with this booking system influences its adoption over time. We found that the adoption of pre-ordering was highest among graduate female students (odds ratio 1.67, p <0.001), who also planned their lunches further in advance and for more consecutive days compared to their peers. Our data also suggested that pre-ordering may increase the amount of uncollected orders, a potential source of collateral waste previously not identified in the literature. Although the generalizability of our findings is limited by the unique characteristics of the setting, the results obtained provide novel cues upon which future literature may build.
