The study found that post-meal blood sugar levels dropped 12 per cent on average when the participants followed the walking after meals advice compared to walking at any time of the day.
Most of this effect came from the highly significant 22 per cent reduction in blood sugar when walking after evening meals, which were the most carbohydrate heavy, and were followed by the most sedentary time.
The researchers prescribed walking to 41 patients with type 2 diabetes in two-week blocks, separated by a month. The patients - who were fitted with accelerometers to measure their physical activity and devices that measured their blood sugar every five minutes - were to walk either for thirty minutes a day as advised by guidelines, or to walk for 10 minutes after each main meal.post-meal glucose is regarded as an important target in managing type 2 diabetes, given its independent contribution to overall blood sugar control and cardiovascular risk.
"The benefits relating to physical activity following meals suggest that current guidelines should be amended to specify post-meal activity, particularly when meals contain a substantial amount of carbohydrate," they conclude.
