Scientists reversed biological age in older adults with a 4-week diet change

Scientists at the University of Sydney found that a four-week diet change can reverse biological age in older adults. Participants who reduced fat intake or adopted a more plant-based diet showed improvements in key health biomarkers associated with aging. The most significant results were seen in individuals who followed a lower-fat, higher-carb diet. This diet change led to noticeable improvements, whereas those who stuck to their usual diets saw minimal changes.
