A study reported by mindbodygreen and sourced from a peer-reviewed journal examined whether short-term dietary shifts could alter biological age markers within four weeks. Researchers analyzed 104 participants aged 65 to 75 who were randomly assigned to one of four diets: omnivorous high-fat, omnivorous high-carbohydrate, or two semi-vegetarian options. Biological age was measured using KDM-derived ?Age, an index combining multiple aging biomarkers to estimate physiological age. The study, with a PubMed identifier of 42037549, suggests that dietary composition may produce measurable changes in cellular aging markers over a compressed timeline, according to the report.
Study Design and Methods
Participants were randomly assigned to the four diet groups to assess the impact of macronutrient balance and protein source on biological age. The omnivorous high-fat and high-carbohydrate diets varied primarily in the ratio of fats to carbohydrates, while the two semi-vegetarian options reduced or eliminated animal protein. The researchers used KDM-derived ?Age to estimate physiological age at baseline and again after four weeks of dietary intervention, according to the mindbodygreen report.
