The Study
The Effects of Postprandial Walking on the Glucose Response after Meals with Different Characteristics
This study showed that if you go for a walk after eating, your blood sugar doesn't spike as high right after the meal — but only in healthy young people. It doesn't prove walking makes you healthier long-term or helps people with diabetes.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
After eating, your blood sugar goes up — but walking for 30 minutes starting 15 minutes after your meal helps stop that spike from getting too high.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This means walking helps prevent dangerous spikes after meals, which is good for your heart and metabolism — even if it doesn't reduce the total sugar you absorb.
- 2Walking lowered the peak blood sugar by 25–30% after any meal — whether it was a sandwich or a sugary drink — but didn't lower the total sugar your body got over two hours.

Taking a light walk after eating lowers blood glucose and insulin levels compared to sitting still after eating.
Taking a 30-minute brisk walk 15 minutes after eating lowers the highest blood glucose level by 25-30% in healthy young adults, whether the meal was high or low in carbohydrates or consisted of regular food or a sugary drink.
A drink containing 75 grams of glucose causes higher peak blood sugar levels and greater total glucose exposure over two hours than a solid meal containing the same amount of carbohydrate, due to differences in meal composition such as the presence of fat and protein.
Walking after eating lowers the peak blood glucose level by a similar amount whether the meal is a sugary drink or a meal with protein and fat, even though the sugary drink causes higher overall blood glucose increases.
Walking after eating lowers the highest blood glucose spike but does not change the overall average blood glucose level over two hours, meaning the total amount of glucose in the blood over time remains the same.
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.
