    Skipping breakfast negatively impacts problem-solving skills in 9- to 11-year-old children. This study highlights how meal timing affects cognitive performance and behavior in developing minds.

    Area of Science:

    • Child Psychology
    • Nutritional Neuroscience
    • Cognitive Performance

    Background:

    • Short-term fasting, such as skipping breakfast, may influence cognitive functions.
    • Understanding the impact of meal timing on children's cognitive abilities is crucial for academic success.

    Purpose of the Study:

    • To investigate the effects of short-term fasting on problem-solving performance in children aged 9–11 years.
    • To assess the relationship between fasting, blood glucose/insulin levels, and cognitive function.

    Main Methods:

    • Controlled study in a metabolic ward with 9–11-year-old children.
    • Behavioral assessments included IQ, Matching Familiar Figure Test, and Hagen Central Incidental Test.
    • Blood samples analyzed for glucose and insulin levels under both fasting and non-fasting conditions.

    Main Results:

    • Skipping breakfast led to impaired problem-solving performance in the late morning.
    • Fasting conditions showed adverse effects on cognitive tasks compared to non-fasting conditions.
    • Significant correlations observed between meal timing, physiological markers, and behavioral outcomes.

    Conclusions:

    • Short-term fasting (skipping breakfast) adversely affects children's problem-solving abilities.
    • Meal timing and nutrient composition have demonstrable acute effects on children's behavior and cognition.
    • Findings underscore the importance of regular, nutrient-rich meals for optimal cognitive function in children.
