Research presented at the European Congress on Obesity (ECO 2026) in Istanbul found that walking approximately 8,500 steps a day was associated with meaningfully better long-term weight-loss maintenance, challenging the widely assumed 10,000-step benchmark, which originated from a 1960s Japanese pedometer marketing campaign rather than clinical research.
The study, a systematic review and meta-analysis published in the International Journal of Environmental Research and Public Health, found that daily step count was not strongly associated with how much weight participants lost initially -- but was significantly associated with how well they kept that weight off afterward. Participants in lifestyle-modification programs increased their steps from a baseline of roughly 7,280 to about 8,454 by the end of an active weight-loss phase, and sustained around 8,241 steps during the maintenance phase, while a control group's step count remained largely flat.
Study co-author Professor Marwan El Ghoch of the University of Modena and Reggio Emilia noted that preventing regain remains the central challenge in obesity treatment, citing research suggesting that roughly 80% of people who initially lose weight regain some or all of it within three to five years.
Researchers framed the step-count target as a practical, low-cost intervention that doesn't require specialized equipment, and suggested gradual increases of 250 to 500 steps every few days as a realistic way to build toward the goal.
Activity level is one of the direct inputs in our Weight Loss Reality Simulator, and this research reinforces why the maintenance phase, not just the losing phase, deserves its own plan.
