Researchers reported that eating within a nine‑hour window and fasting for four hours before bedtime may help preserve cognitive function in older adults. A pilot trial enrolled 47 overweight or obese women aged 50 to 79 and assigned 26 to eat only between 10 a.m. and 6 p.m. while the remaining 21 spread meals across roughly 12 hours. Both groups reduced calorie intake by about 500 calories per day for six months and lost an average of 7 kg (15 lb). Cognitive testing at the study’s conclusion showed the time‑restricted group performed better on spatial planning and problem‑solving tasks and made fewer errors on memory and learning measures, though performance on multitasking and reaction‑time tests was similar for both groups. The lead researcher, Prof. Sue Shapses of Rutgers University, described the effects as modest but said they suggest that timing of meals may aid everyday memory and reduce attention‑related mistakes. The findings were presented at Nutrition 2026, the annual meeting of the American Society for Nutrition in Maryland. The team plans larger trials to confirm the results and to explore the mechanisms, which may involve circadian rhythms, metabolism and inflammation. Prof. Wendy Hall of King’s College London, who was not involved in the study, noted that time‑restricted eating could support brain health by improving weight management, blood‑sugar control, vascular function and reducing inflammation. She cautioned that the data are preliminary and that peer‑reviewed publication is needed to determine clinical relevance.
