Children playing these video games increased FV consumption by about 2/3 serving per day, but did not increase water consumption or moderate to vigorous physical activity, or improve body composition. Despite the increase, FV and water consumption and physical activity remained below the minimum recommendations.

In this randomized clinical trial, 153 children ages 10 to 12 years, were divided into a treatment group (103 children) and a control group (50). Complete data were obtained on 133 subjects. The treatment group first played Diab and then Nanoswarm. The control group played diet and physical-activity knowledge-based games on popular websites. Each group was assessed at the start of the trial, immediately after Diab, immediately after Nanoswarm, and again two months later. Height, weight, waist size, and triceps skin-fold thickness were measured. Physical activity was monitored for at least 4 days by accelerometer-based data from each child at each assessment. Food consumption was measured using 24 hour dietary recalls conducted by registered dietitians.
