Scientists reversed biological age in older adults in just 4 weeks

Researchers from the University of Sydney found that older adults aged 65 to 75 who changed the ratio of fat, carbohydrates, and animal protein in their diet showed signs of lower biological age after just four weeks. Biological age is an estimate of how old the body appears based on its health and physiological condition, not on the number of years lived. The study included 104 participants divided into four diet groups. Three of these groups (all except the omnivorous high-fat diet group) showed a reduction in biological age. The strongest results appeared in the omnivorous high-carbohydrate group, where participants consumed 14 percent of energy from protein, 28-29 percent from fat, and 53 percent from carbohydrates. However, researchers emphasize that these are preliminary findings and longer studies are needed to determine whether the changes persist and whether they translate into a lower risk of age-related diseases.
