Study design
This randomized pilot assigned healthy women to four weeks of 16:8 time-restricted eating (23 participants) or usual eating (20). Participants completed weekly working-memory and attentional-control tasks and reported well-being and body weight.
Findings
Working memory and attention scores improved over time, but the groups did not differ significantly on the cognitive outcomes. The fasting group had a statistically significant reduction in BMI relative to controls, and reported adverse events did not differ between groups.
Limits and disclosures
This short pilot included only healthy women and cannot establish longer-term effects or generalize to other populations. It found no evidence of a time-restricted-eating-specific cognitive improvement or impairment. One author reported Health Research Council of New Zealand support; other authors reported no known competing interests.
