8-Hour eating window may alter breast cancer risk markers

This study tested whether eating only during an 8-hour window each day (time-restricted feeding) changes certain blood markers linked to breast cancer risk. Twenty-nine postmenopausal women with prediabetes were randomly assigned to either an 8-hour eating period or a 12-hour or longer eating period for about 3.5 months. Researchers measured changes in advanced glycation end products (AGEs) and related receptors, as well as insulin and other factors, to see if this eating pattern might reduce cancer risk.
