Walking for just two minutes after a meal can keep blood sugar from spiking. With the number of diabetes patients in South Korea topping 6 million, the habit is drawing attention because it requires no money and no equipment.
South Korea had 6 million diabetes patients aged 30 and over as of 2025, or roughly one in seven adults, according to the Korean Diabetes Association on the 20th. Counting people with prediabetes, more than 20 million are exposed to blood sugar problems. The incidence rate among people in their 20s and 30s rose 120% from 2019, making it no longer a condition confined to middle-aged and older adults.
When food is eaten, carbohydrates break down into glucose and are absorbed into the bloodstream. The pancreas releases insulin to regulate blood sugar, but sitting still after a meal causes a blood sugar spike, in which levels surge sharply and then fall. Repeating that cycle builds insulin resistance and overloads the pancreas, raising the risk of developing diabetes.
Ronald R. Quinton, a doctor at Tulane University School of Medicine in the United States, said that just two minutes of light walking contracts the muscles and increases glucose uptake, bringing blood sugar down. A study published in the international journal Sports Medicine in 2023 also found that a short walk after eating suppressed increases in blood sugar far more effectively than sitting still.
Vegetables First, Rice Last: Changing the Order Changes Blood Sugar
Along with walking, the order in which food is eaten is a key variable in preventing blood sugar spikes. One South Korean study found that walking within 10 minutes of finishing a meal lowered peak blood sugar by 17.6. In its 2026 clinical guidelines, the American Diabetes Association recommended standing up or walking briefly at least every 30 minutes.
Even with the same menu, picking up the spoon in the order of fiber, protein and then carbohydrates can substantially ease blood sugar spikes. Fiber, abundant in vegetables, forms a protective layer on the intestinal wall that slows the rate at which carbohydrates break down into glucose.
Refined carbohydrates such as white bread, pasta and sweet desserts raise blood sugar quickly, so moving the body immediately after eating helps. For those who cannot go outside, marching in place, heel raises and light squats are alternatives. The key is to work the muscles in the legs and torso.
