The Claim

In healthy young adults, postprandial walking reduces the glucose peak after meals with high carbohydrate content (1.5 g/kg) to a similar extent as after meals with moderate carbohydrate content (0.75 g/kg), but the overall glycemic response over two hours is less improved following high-carbohydrate meals due to a rebound in glucose levels during the second hour.

In plain English

In healthy young adults, walking after eating lowers the spike in blood sugar after a high-carb meal just as much as after a moderate-carb meal, but blood sugar rises again in the second hour after the high-carb meal, resulting in a less favorable overall response over two hours.

See the scientific wording

In healthy young adults, postprandial walking reduces the glucose peak after meals with high carbohydrate content (1.5 g/kg) similarly to meals with moderate carbohydrate content (0.75 g/kg), but the overall glycemic response over two hours is less improved after high-carbohydrate meals due to a rebound in glucose levels during the second hour.

Why this might work

When you walk after eating, your muscles pull sugar out of your blood to use for energy, which lowers the initial spike. But if you ate a lot of carbs, your gut keeps releasing sugar slowly for hours, and your liver also releases more sugar to match the load. The walk helps at first, but it doesn't last long enough to stop all that extra sugar coming in, so your blood sugar rises again later.

  1. Study: The Effects of Postprandial Walking on the Glucose Response after Meals with Different Characteristics

    Walking after eating lowers your blood sugar spike no matter if you ate a lot of carbs or just a moderate amount—but when you eat a huge amount of carbs, your blood sugar goes up again later, so walking helps less overall.
