Research indicates that walking after meal help lower post meal glucose levels in people. Walking after meal is good for body, it aids in digestion and also burns calories.
For people who do not experience abdominal pain, fatigue, or other discomfort when walking just after a meal, walking at a brisk speed for 30 minutes as soon as possible just after lunch and dinner leads to more weight loss than does walking for 30 minutes beginning one hour after a meal has been consumed.
At 4.5 hours after eating, people with diabetes had a glucose level 145% higher, on average, after inactivity than after walking. In people without diabetes, there was a roughly 113% increase at 4.5 hours after eating after inactivity compared to after walking. In general, walking begins to affect glucose levels ten minutes after the exercise starts and the benefits extended until five minutes after it had stopped; the improvement was roughly 30 mg/dl. Substituting other physical activities, such as hand-washing dishes, after meals might have the same blood glucose benefits.
