Skipping breakfast doesn’t hurt thinking ability in healthy adults

Skipping breakfast or intermittent fasting doesn’t impair cognitive function in healthy adults in the short term, a new study finds.

Why it matters

  • Fasting and intermittent fasting are popular trends, and understanding their cognitive effects is important.
  • Previous studies have shown mixed results, so this study provides clarity.

By the numbers

  • 100 healthy adults participated in the study.
  • 71 studies and 3,484 participants were included in the meta-analysis.
  • Fasting intervals longer than 12 hours showed modest reductions in cognitive performance.

The big picture

  • Short-term fasting does not significantly impair cognitive function in healthy adults.
  • Children may be more vulnerable to the effects of fasting on cognitive performance.
  • Cognitive performance is more affected by food-related stimuli during fasting.

What they're saying

  • Personal anecdotes highlight individual differences in how food intake affects cognitive performance.
  • Experts note nuances in fasting effects, particularly in children and with longer fasting periods.

Caveats

  • The study focused on short-term effects, and long-term impacts were not assessed.
  • Children showed greater performance deficits compared to adults.

What’s next

  • Further research could explore the long-term effects of fasting on cognitive performance.
  • Studies could investigate the impact of different fasting durations and their effects on various age groups.
