Reaching a target weight is a major accomplishment, but for many people the real challenge begins afterward, when lost weight gradually returns. New research suggests that maintaining a moderate level of daily walking could play an important role in preventing regain.
A systematic review and meta-analysis of randomized controlled trials identified a practical activity benchmark: approximately 8,500 steps per day, started during weight loss and maintained afterward. Researchers found that this level of walking was associated with greater weight reduction and improved long-term weight maintenance.
Why Long-Term Weight Loss Is So Difficult
Obesity specialists note that the body often resists lasting weight change. Hormonal shifts, increased appetite, and reductions in energy expenditure can all push people back toward their previous weight, even after months of dieting and lifestyle changes.
Lead author Marwan El Ghoch from the University of Modena and Reggio Emilia points out that roughly 80 percent of people with overweight or obesity regain some or all of their lost weight within three to five years. As a result, finding simple and sustainable strategies to prevent regain remains a major clinical priority.
How The Study Was Conducted
The researchers reviewed 18 randomized controlled trials involving adults with overweight or obesity and ultimately included data from 14 studies in their pooled analysis. Altogether, 3,758 participants with an average age of 53 were followed for approximately 18 months.
In each study, one group participated in a structured lifestyle program that combined dietary changes with increased physical activity, while control participants continued their usual habits.
Researchers evaluated results during two separate stages: an active weight-loss period and a later maintenance phase.
On average, participants in the lifestyle intervention programs lost 4.4 percent of their initial body weight during the active weight-loss stage, significantly outperforming the control groups. Even during the more flexible maintenance phase, they still maintained an average 3.3 percent reduction in body weight.
The Importance Of 8,500 Daily Steps
At the beginning of the studies, both lifestyle and control groups averaged roughly 7,200 daily steps. Over time, however, participants in the lifestyle programs steadily increased their activity levels, reaching about 8,454 steps per day during the weight-loss phase and around 8,241 daily steps during maintenance.
Meanwhile, the control groups increased activity only slightly—to approximately 7,486 steps daily—and did not achieve meaningful weight loss.
The findings suggest that consistently increasing daily movement above baseline levels, rather than simply maintaining existing habits, may help protect against gradual weight regain.
The researchers caution that the 8,500-step figure should not be interpreted as a rigid rule. Instead, they describe it as a practical and evidence-based benchmark that may help guide patients and healthcare providers.
Why Fewer Than 10,000 Steps Can Still Be Effective
The popular goal of 10,000 steps per day has long been promoted as a health target, although it was never based on a clearly defined physiological threshold.
More recent large-scale research has shown that important health benefits—including reduced cardiovascular risk and lower mortality—often begin at lower activity levels.
This new analysis supports that idea, suggesting that maintaining weight loss does not necessarily require extremely high volumes of exercise. For many adults, aiming for approximately 8,500 steps per day may feel more realistic and sustainable while still offering significant metabolic and cardiovascular benefits.
Researchers also found that daily step count appeared to matter even more during the maintenance stage than during the initial weight-loss phase. This supports the idea that physical activity becomes especially important after calorie restriction eases and the body naturally attempts to regain lost weight.
What This Means For Weight Management
For people who have already lost weight, researchers say the key message is not to abandon physical activity once progress appears on the scale. Maintaining or slightly increasing daily step counts may help stabilize metabolism and counter gradual increases in calorie intake over time.
From a public health perspective, step targets are relatively easy to implement because most smartphones and wearable devices automatically track daily movement. This gives individuals immediate feedback and a simple metric they can monitor consistently.
The researchers emphasize that daily steps represent only one part of comprehensive weight management, which should also include balanced nutrition, adequate sleep, and stress management.
Still, walking remains one of the most accessible, affordable, and sustainable habits for long-term weight control.
The authors say further studies are needed to evaluate different step targets and better understand how walking requirements may vary depending on age, health status, and metabolic conditions.
For now, the research offers a practical takeaway: adding roughly 1,000 to 1,500 extra steps beyond a typical baseline may help determine whether weight loss is maintained—or slowly regained over time.
The findings were published in the International Journal of Environmental Research and Public Health and add to growing evidence that moderate, consistent physical activity may be just as important as short-term intensive efforts in long-term obesity management.
