Diet May Slow Aging in Just 4 Weeks | Science News

New research from Australia reveals that older adults aged 65-75 can potentially reverse biological aging markers in just four weeks by adjusting their diet—cutting back on fat or animal protein. In a study of 104 participants, three dietary groups showed reduced biological age, with the highest impact seen in those eating a high-carb, low-fat omnivorous diet. The high-fat group saw no change. While exciting, scientists caution these findings are preliminary: effects may not be permanent, and long-term studies are needed to determine if this translates to lower disease risk or extended lifespan.
