^aBaseline: For steps, baseline is defined as average steps per day 6 days prior to enrolling in the trial, and for shopping-related outcome variables, baseline is defined as the nutritional value of all foods purchased within the 4 weeks before the trial.

^bT1: week 1-4 average values.

^cT2: week 5-8 average values.

^dT3: week 9-12 average values (end of study).

^eFSA-NPS DI: British Food Standards Agency Nutrient Profiling System Dietary Index.

^fFSA-NPS DI point scale: −15 most healthy to +40 least healthy.
