Can Lifestyle Changes Actually Reverse Aging?

Maybe you’ve heard the word “telomere”; it’s been getting a lot of action lately. Telomeres are like biological clocks built into us on a cellular level. They cap our chromosomes and stop them from unraveling (in the photo above, they’re colored yellow), and they get shorter as our cells divide. Eventually, they get so short that they can’t do their job, leading to the death of cells and the onset of some of the chronic diseases many of us experience as we get older, along with cancer, dementia and other diseases of aging.

 

The Study

 

This month, The Lancet published a small study by a team at the University of California, San Francisco that suggests we can reverse this cellular clock by making some simple lifestyle changes.

Lead author Dean Ornish told LiveScience, “A number of studies have shown that as telomeres get shorter, the risk of premature death – and most chronic disease, from heart disease to cancer, even dementia – goes up.” This study was unusual in that it saw a lengthening of telomeres; in other words, a reversal of the aging process.

In the study, one group of men was given a regime of exercise, healthy diet, stress reduction and social interaction, while a second group made no changes to their lifestyles. After five years, the first group’s telomeres had lengthened by an average of 10 percent, while the second group’s had shortened by three percent.

The UCSF study was too small to be conclusive, but its author says the findings are significant. In the past, Ornish was responsible for early studies showing we can reverse heart disease through lifestyle changes.

Watch Ornish discuss the study, or read on to learn about the specific lifestyle changes the men made.

 

Age-Friendly Lifestyle Changes

This infographic from UCSF shows what the lifestyle of the first group of men looked like. When the researchers measured the telomeres in the men’s white blood cells, those who had followed the regime most faithfully showed the most lengthening.

  1. As part of the “Baby Boomers” era I know I’m
    not alone in dealing with these aches and pains of mine on a daily basis. I find much comfort in knowing that I’m part of this “Senior Cult” ….Makes me appreciate what parts of my skeleton DO function and what my Spirit and I can do to tolerate the remaining daily aches and pains….I thank you sincerely for your website!
