That ten-thousand-step ring on your fitness tracker still has a gap left every evening, and many people start circling their neighborhood to close it.

Finishing the loop feels good, but some people grow more puzzled the more they walk: who set this number anyway? If you're two thousand steps short, did all the earlier steps go to waste?

In August 2025, an analysis in The Lancet Public Health pooling 57 studies and 35 cohorts gave an answer that differs from what many people think: 7,000 steps is enough, associated with a 47% lower all-cause mortality risk than 2,000 steps[1]. And the number "ten thousand steps" was explicitly described as "lacking supporting evidence" in a 2022 pooled analysis in the same journal[2].

The five questions below are among the ones most frequently asked in clinic and in our backstage messages.

Q1: Is ten thousand steps a research conclusion or a marketing slogan?

It is not a research conclusion.

The 2022 pooled analysis, which included 47,471 adults from 15 countries, stated plainly: ten thousand steps a day is widely promoted, but there is little evidence supporting this recommended value[2]. It is more a case of commercial promotion running ahead of the evidence—pedometer sellers needed a round-number goal.

In plain terms: ten thousand steps is not a medical red line; it is just an easy-to-remember round number.

Q2: So how many steps are actually useful?

Three numbers, from low to high:

Age affects where the curve flattens: for those over 60, it tends to level off after about 6,000 to 8,000 steps, while for those under 60 it takes 8,000 to 10,000 steps[2].

In plain terms: start with "walk two thousand more steps a day" rather than locking horns with ten thousand right away.

Q3: Is walking fast more important than walking a lot?

Both matter, but don't get the order backwards.

Data from 78,430 UK adults showed that accumulating 30 minutes of continuous brisk walking a day, reaching 112 steps per minute, reduced dementia risk to 38% of that of the control group[5]; in the same dataset, a dose of 6,315 deliberate brisk steps was more effective than 3,677 scattered steps[5].

But there is also evidence to the contrary: among 16,741 older women, after adjusting for total daily steps, differences across intensity measures were largely no longer significant[4]. In other words, when total volume is insufficient, speed can't save you.

In plain terms: accumulate steps first, and once you reach 7,000, pick 20 to 30 minutes of them to walk faster.

Q4: Can walking really protect the brain and prevent dementia?

Yes, and the dose-response relationship is fairly clear.

In the same 78,430 people, followed for 6.9 years with 866 incident dementia cases: the peak of the dose curve was at 9,826 steps a day, where risk dropped to 49%; but 3,826 steps already cut it in half—that is, reached half of the benefit at that dose[5]. In the 2025 pooled analysis, 7,000 steps compared with 2,000 steps was associated with a 38% lower dementia risk[1].

In plain terms: you don't need ten thousand steps to protect your brain; 4,000 steps is enough to start, and more is better but with diminishing returns.

Q5: When it's cold and I can't get moving, how do I rack up enough steps?

Three methods that don't rely on willpower:

One more reminder: the above are all observational studies, showing that "people who walk more have lower risk," which does not equal "walking more will definitely extend your life." People with knee problems or cardiovascular disease should ask their doctor before starting.

Three Things You Can Do This Week

Step count is an easily quantified health behavior: it doesn't depend on talent, only on whether you went out today.
