A recent clinical trial suggests that modest lifestyle changes may slow the body's biological aging process. The study aimed to assess whether simple habits could influence cellular age.
The 12‑week study involved 48 overweight men aged 50 to 74, who were divided into an intervention group and a control group that maintained usual habits.
Participants in the intervention group followed a structured routine that included daily consumption of 100 grams of plain yogurt, personalized dietary guidance to reduce overeating and eliminate sugary drinks, and at least 30 minutes of walking or stepper use three days per week.
Blood samples were collected before and after the trial, and DNA was analyzed for epigenetic markers of cellular age using a tool that calculates the rate of biological aging.
The intervention group experienced a statistically significant reduction in the pace of biological aging, averaging a 2.2 percent slowdown.
This slowing is comparable to the effect seen in a separate study where participants cut daily calorie intake by 25 percent over two years.
The age‑slowing effect appeared independent of weight loss or the exact number of exercise sessions logged.
An additional finding was a notable improvement in a DNA marker associated with kidney function.
Because the intervention combined probiotics, diet, and exercise, the study concludes the anti‑aging benefits arise from their combined effect rather than any single component.
The study acknowledges limitations, including its small sample size, short duration, and focus on overweight men from a single nationality.
