Rutgers study finds nine‑hour eating window improves cognition in older overweight women
A six‑month pilot trial recruited 47 women aged 50‑79 who were overweight or obese. All participants followed a weight‑loss program that cut daily calories by about 500 kcal. Twenty‑six of them were instructed to eat all food within a daily window of fewer than nine hours—usually between 10 a.m. and 6 p.m.—and to stop eating at least four hours before bedtime. The remaining participants ate over a roughly 12‑hour period.
Both groups lost a similar amount of weight, about 7 kg (≈15 lb). Cognitive testing showed that the time‑restricted eating group performed better on spatial‑planning and problem‑solving tasks and made fewer errors on memory and learning tests, although the latter differences were not statistically significant. No differences emerged in multitasking or reaction‑time tests.
The study was led by nutrition scientist Sue Shapses of Rutgers University and presented at Nutrition 2026, the annual meeting of the American Society for Nutrition in National Harbor, Maryland, USA. Researchers say the results suggest that limiting daily eating hours may modestly reduce dementia risk, but larger trials are needed.
