Slash your biological age by up to 16 years by doing this one thing during your daily walk — new study says

There’s a way to roll back the clock on your biological age — and, according to a new(ish) study, you can do it on your daily walk. No frills, no nonsense, just a small tweak for big results.

We already know there are many benefits to walking, including a boost to your cardiovascular health, stronger muscles, bones and joints, ramped up calorie burn, a healthier metabolism and better mood and emotional wellbeing.

If that’s not enough, research straight out of Britain has shown that one particular aspect of your walks could supercharge your results, including reducing your biological age by up to 16 years. Yep, you read that correctly.

And no, it’s not 10,000 steps, a weighted vest, or walking backwards. This is the one thing you need to know the next time you lace up a pair of the best hiking boots and head out.

What is the study?

Research, published in Nature in 2022, found that your speed could play a role in cutting your biological age. The study assessed over 400,000 Brits and biological age (how quickly you’re aging based on chemical markers) and found that speed made a difference.

Results showed that those with a steady to average and brisk walking pace “had significantly longer LTL compared with slow walkers.” LTL, meaning leucocyte telomere length, is a marker of biological age.

Using “accelerometer-assessed measures of physical activity,” the researchers found associations between longer LTL and “habitual activity intensity,” rather than total amount of activity. In other words, your pace may do more for your health than total steps.

While it’s true that the more you move during the day, the better for your metabolism and overall health, we now know that you don’t need 10,000 steps every day to maximize it; as little as 7,000 steps per day could be enough!

But if you plan to track your step count, making your walk more brisk could be more beneficial across the same distance than an amble. That said, I love a slow walk, and recently took up intuitive walking to boost mindfulness, so I’m a firm believer in a time and place for everything.

Given that brisk walking, like power walking, can have a positive impact on weight management and cardiovascular fitness, it checks out that this could also improve your biological age, too.

So what about speed? The study used self-reported walking pace, providing participants with a touchscreen Q&A and response options of “slow,” “steady/average,” or “brisk.”Slow pace was defined as less than 3mph, steady pace was between 3 -4mph and brisk walking was over 4mph.

Time to take a walk

There you have it. A faster walking pace is associated with longer LTL, potentially cutting up to 16 years off your biological age. The study showed that brisk walkers had a biological age of up to 16 years younger, and that brisk walking could lead to a younger biological age rather than the other way around.

The study also suggests that time spent habitually in higher-intensity activities like brisk walking had a stronger association with biological age than the total amount of walking or distance.

All in all, this supports the idea that more intensive and habitual movement, like increased walking pace, can impact biological markers and overall health. And better still, if you increase your pace, even a short walk could boost longevity.
