8,500 Steps Daily Might Prevent Post-Diet Weight Gain

Select Language:

A lot of people find losing weight to be tough, but sticking with it and keeping the weight off can be even more challenging. Doctors and researchers have known for some time that many individuals who successfully shed pounds tend to regain at least some of that weight within a few years.

Recent research indicates that a simple daily habit—walking around 8,500 steps—could be key to long-term weight maintenance. These findings will be shared at the 2026 European Congress on Obesity in Istanbul, Turkey, and are also set to be published in the International Journal of Environmental Research and Public Health.

The study offers fresh evidence that maintaining a higher daily step count might help prevent weight regain after dieting. Obesity remains one of the world’s major health issues, linked to increased risks of conditions like type 2 diabetes, heart disease, high blood pressure, sleep apnea, joint issues, and certain cancers.

While many can lose weight through dieting or lifestyle programs, keeping that weight off is often extremely tough. Professor Marwan El Ghoch from the University of Modena and Reggio Emilia in Italy pointed out that preventing weight regain is one of the biggest hurdles in treating obesity. About 80% of people who lose weight tend to gain some or all of it back within three to five years.

Researchers have been on the hunt for practical, affordable strategies to help individuals sustain long-term weight loss. Since walking is simple, inexpensive, and accessible to many, it’s often recommended. However, surprisingly little evidence has existed regarding how daily step counts influence long-term weight maintenance.

To explore this, scientists conducted a comprehensive review and meta-analysis, combining data from many previous studies to identify common patterns more clearly. They examined 18 randomized controlled trials, ultimately including 14 studies in their analysis. These involved a total of 3,758 adults from countries like the U.S., U.K., Australia, and Japan, with an average age of 53 and a body mass index around 31—classified as obese.

Participants were split between those enrolled in lifestyle modification programs that combined dietary advice with increased walking and those who followed diet-only plans or received no intervention. These programs tracked daily steps and body weight during both weight loss and maintenance phases designed to prevent weight regain.

At the start, both groups averaged about 7,200 daily steps. During the weight loss phase, those in the lifestyle programs increased their steps to roughly 8,454 per day. This led to an average weight loss of about 4.39%, or around 4 kilograms (about 9 pounds). Notably, participants kept up their higher step counts during the maintenance phase, averaging about 8,241 steps daily, which helped them retain most of their weight loss—around 3.28%, or approximately 3 kilograms (6.6 pounds).

A clear link emerged: higher daily step counts were associated with a lower chance of regaining weight. Participants who maintained active walking routines after initial weight loss were more successful at sustaining their results. Interestingly, walking more didn’t significantly correlate with greater weight loss during the early dieting period — likely because calorie reduction has a bigger short-term impact than physical activity alone. However, walking played a more pivotal role in avoiding weight regain later on.

This finding is particularly valuable because many people become discouraged after regaining weight following successful dieting. The study suggests that consistent walking could serve as a straightforward, sustainable way to support long-term weight management. Plus, walking requires no costly equipment, gym memberships, or complicated routines. For many, especially older adults or those with limited fitness levels, walking might be one of the easiest forms of exercise to stick with.

The researchers also pointed out that lifestyle programs offering guidance on diet and activity can bring additional benefits, such as improved heart health, lower blood pressure, better blood sugar control, enhanced mood, and increased overall fitness. Still, they caution that walking alone isn’t guaranteed to cause sustained weight maintenance; factors like diet, motivation, social support, and lifestyle changes all play roles.

Nonetheless, the evidence suggests aiming for around 8,500 steps per day could be a realistic goal for those looking to avoid regaining weight after dieting. Professor El Ghoch emphasized that increasing daily steps to this level is a simple, inexpensive strategy that could help many people keep their weight off.

Overall, the findings highlight the importance of cultivating long-term habits instead of relying solely on short-term dieting. Consistent daily activity may be crucial in maintaining a healthier body weight over time.

These results will be shared at the European Congress on Obesity 2026 and published in the International Journal of Environmental Research and Public Health.
