We previously reported decreased food intake (FI) after a glucose drink and 30 min of video game playing (VGP) in normal weight boys, but the effect on FI in boys with increased adiposity is unknown. Therefore, we examined the effect of 30 min of pre‐meal VGP on subjective appetite, emotions and FI in overweight/obese (>85th BMI percentile) boys after a glucose drink. On four mornings, in random order and one‐week apart, boys (n = 22; age = 11.9 ± 0.3 y) consumed equally sweetened drinks (250 mL) of sucralose (0 kcal) or 50 g (200 kcal) glucose, with or without 30 min of subsequent VGP, 2 h after a standardized breakfast. Immediately after all test conditions FI (mean ± SEM kcal) from an ad libitum pizza meal was measured. Subjective appetite was measured at baseline (0 min), 20, 35, and 65 min (post‐meal). While glucose (p < 0.01) decreased FI (∆ = ‐103 ± 48 kcal) compared with the sucralose control, cumulative FI (drink kcal + meal kcal) was higher (p < 0.01). Fullness (p < 0.05) was lower, and subjective aggressiveness (p < 0.01), excitement (p < 0.01), upset (p = 0.05), and frustration (p < 0.05) higher after VGP; however, subjective emotions did not correlate with FI. In conclusion, the stronger effect of glucose compared with VGP on FI is indicative of the primary role of physiologic factors in the short‐term regulation of FI in overweight/obese boys.
