Taking just a couple of minutes to stroll after a meal can noticeably soften the rise and fall of blood sugar. A 2022 meta-analysis in Sports Medicine pooled seven controlled trials that interrupted prolonged sitting with very light walking or simply standing. Light walking for two-to-five minutes every half-hour reduced post-meal glucose far more than remaining seated and outperformed standing breaks as well.
The effect was consistent in adults of different ages and weight ranges, including people with type 2 diabetes. Researchers saw the greatest benefit when the short walks happened within 60–90 minutes of eating, the window when blood sugar usually peaks.
Standing helped a little, but moving your legs made muscles soak up more circulating glucose without extra insulin. Regularly blunting these post-meal spikes is thought to lower long-term risks of cardiovascular disease and metabolic disorders.
Because the walking bouts were so light and brief, the habit is easy to fold into daily life, pacing during phone calls, a short hallway loop at work, or a quick street stroll after dinner all count. Even small, repeatable movements appear to offer meaningful protection for blood-sugar control.

The authors analyzed seven short-term crossover trials and found that 2–5 minute bouts of light walking every 20–30 minutes cut post-prandial glucose and insulin more than either uninterrupted sitting or standing breaks.

Reviewing eight trials, the team showed that exercising immediately after meals lowered glucose significantly more than exercising beforehand, reinforcing the practical value of brief post-meal walks
