Objectives: Consumption of excess sugar, a common energy-dense nutrient-poor food, is a risk factor for obesity in school-aged children. Food-specific inhibition training, where responses to palatable food stimuli, such as sweet foods, are consistently and repeatedly inhibited, reduces sweet food intake in adults. However, no studies have yet examined the effectiveness of inhibitory control training specifically targeting sweet foods among children with high sugar cravings. We examined whether sweet food-specific inhibitory control training (SF-ICT), administered via a mobile app, reduced choice and consumption of sweet foods, and weight in a sample of children aged 7-11 with overweight or obesity and who had high sugar cravings (N = 46).

Design: This study was designed as a 2 × 3 between-within design.

Methods: Participants were randomly allocated to a single-blind design with two conditions: they either received 7 sessions of active or control go/no-go training in which either sweet foods or non-food cues were paired with no-go signals. Participants' weight, sweet food choice, and consumption were measured pre and post-training, and at three-month follow-up.

Results: The results revealed that participants in the active group showed a significant reduction in sweet food choice and intake from pre to post-training relative to the control group. The effects of the training on reducing sweet food intake persisted over the 3-month follow-up No significant changes in weight loss were observed.

Conclusions: These results provide preliminary evidence that sweet food-specific inhibitory control training (SF-ICT) via a mobile app is effective in modifying eating behavior among children with excessive consumption of sugary foods. Further research is required to clarify under what conditions the benefits of training would expand to weight loss.
