A Spanish study investigates whether a very low-calorie ketogenic diet can slow aging at the molecular level, focusing on individuals with obesity. Published in Nutrients, the study suggests that about six months on this diet may influence markers of biological age. Researchers tracked DNA methylation and other epigenetic changes, finding that overweight participants starting with signs of accelerated aging showed improvements indicative of a younger biological age after 180 days on the regimen.
