DEEP DIVE
The Walking Plan That Kept Back Pain Away
If you have had low back pain once, there is a good chance it will come back. About 70 percent of people have another episode within a year of getting better.
A team in Australia wanted to know if something as simple as walking could stop that. Their trial, called WalkBack and published in The Lancet, recruited 701 adults who had just recovered from an episode of low back pain. None of them were walking regularly for exercise.
Half were put on a walking programme. Over six months they had six sessions with a physiotherapist, three of them short phone calls. The physio built a walking plan around each person and also explained how back pain works, how to stop fearing movement and how to manage a small flare-up on their own.
The goal was to build up to walking at least 30 minutes, five times a week, by six months. Everyone got a pedometer and a walking diary.
The other half got no treatment from the trial, though they were free to see anyone they liked.
People were followed for one to three years. The walking group went a median of 208 days before their back pain returned badly enough to limit daily life, compared with 112 days in the control group. That is nearly twice as long without a flare-up. Overall, the risk of that kind of recurrence was 28 percent lower.
In the first year, walkers were also 43 percent less likely to have a flare-up that sent them to a health professional. And it was good value: the researchers put the chance that it was cost-effective at 94 percent.
The trial does have limits. Nobody was blinded, so people knew which group they were in, and they reported their own back pain. Most participants, 81 percent, were women, with an average age of 54. Walking and education were tested together, so we cannot say which part did the most. And walkers had more problems in their legs and feet: 100 events against 54 in the control group, even though the number of people with any side effect was similar.
Still, this was a large trial with a clear result. So if your back has settled after a bad spell, a regular walk may be one of the best ways to keep it that way.
The Protocol
Start Small: Nobody jumped straight to long walks. In the first week, people walked a median of 80 minutes in total, spread over about three walks. By week 12, that was up to 130 minutes a week over about four walks.
Build To 30 Minutes: The target by six months was 30 minutes, five times a week. It was a guide, not a rule, and the physio adjusted it to each person's fitness, health and schedule.
Track Your Walks: Everyone used a pedometer and a walking diary for the first 12 weeks. The step counter on your phone does the same job.
Go Gradually: Walkers had more leg and foot problems, so add time slowly. If your back pain is severe, new or not settling, see a physiotherapist or GP first.
PILLAR SPOTLIGHT · NUTRITION & CELLULAR HEALTH
A Small Handful Of Nuts A Day
Nuts get a bad name because they are high in calories. The research suggests a small handful a day is worth it.
A large review in BMC Medicine pooled 20 long-term studies from around the world. The analysis of deaths from any cause covered more than 800,000 people.
Each extra 28 grams of nuts a day, about a handful, was linked to a 22 percent lower risk of dying during the studies. It was also linked to a 29 percent lower risk of coronary heart disease and a 15 percent lower risk of cancer. Peanuts and tree nuts gave similar results.
You may not even need a full handful. Most of the benefit showed up by about 15 to 20 grams a day, with little extra above that.
These were observational studies, so they show a link, not proof. People who eat nuts may simply have healthier habits. But nuts are cheap, filling and easy. Keep a jar of plain, unsalted nuts within reach and have a small handful a day.

THE SUMMARY
Key takeaways
The WalkBack trial, published in The Lancet in 2024, randomised 701 adults who had recently recovered from low back pain.
A walking and education programme, with six physiotherapist sessions over six months and a target of 30 minutes five times a week, cut the risk of an activity-limiting recurrence by 28 percent.
The median time to a recurrence was 208 days with the programme and 112 days without, and the programme had a 94 percent chance of being cost-effective.
The trial was not blinded, 81 percent of participants were women, and walkers had more leg and foot problems (100 events against 54).
A 2016 review in BMC Medicine linked each extra 28 grams of nuts a day with a 22 percent lower risk of death, with most of the benefit by 15 to 20 grams a day.
