Study setting
weight loss
We developed a bespoke module on the physiology of weight loss in collaboration with two subject matter experts. Three features of the module are worth noting. First, the module included 29 embedded hyperlinks to references and key resources. Second, the module included four ‘interactive’ sections where students could manipulate input variables (e.g., the macronutrient composition of a diet) and observe their effects (e.g., on the thermic effect of food). Third, the module included five ‘question’ slides where students were presented with a question (e.g., what strategies might help to attenuate the reduction in the thermic effect of food associated with weight loss?) and could click to reveal the answer. The module was designed to take about 45 minutes to complete. Four second- through fourth-year medical students piloted the module and reported that it reflected the right level of challenge for first- and second-year students. We made no subsequent changes to the module and pilot students did not participate in the trial.
