8-Hour Eating Window May Boost Brain Function Beyond Weight Loss
In a six-month pilot study of 47 older women with overweight/obesity, those who ate within an 8–9 hour window as part of a calorie-reduction plan showed greater improvements in spatial planning and problem-solving than those who ate over about 12 hours, despite similar weight loss (~15 lb). The results hint that time-restricted eating may boost certain cognitive functions beyond weight loss alone, but larger trials are needed to confirm and explore underlying mechanisms.
