Walking after a meal is scientifically proven to improve digestion and control blood sugar. It helps accelerate the rate of digestion. In people with high blood sugar levels (diabetes, pre-diabetes), walking for 20 minutes after a meal helps take the edge off the blood sugar spike. In fact 3 short walks after each meal were better for blood sugar control than one long walk during the day.
Not to mention that walking helps burn some calories, clears the mind, and improves your mood.
Important: You need to walk after eating, not while you are eating
Get into the habit of taking a short walk after eating. This is probably easier on the weekend at home, but many of us can sneak in a 15-minute walk after lunch at work too. Buddy up with some office mates and call it a work meeting.
Postprandial walking but not consumption of alcoholic digestifs or espresso accelerates gastric emptying in healthy volunteers.
Postprandial walking is better for lowering the glycemic effect of dinner than pre-dinner exercise in type 2 diabetic individuals.
