Walking after meals and blood sugar
Research that pooled many studies finds that light walking soon after a meal lowers the rise in blood glucose compared with sitting, and the effect is larger when the walk starts soon after eating. The NIDDK recommends at least 150 minutes of moderate activity a week for adults.
Does walking after a meal lower blood sugar?
A systematic review and meta-analysis in Sports Medicine looked at studies of exercise before and after meals. It found that being active after eating lowers the blood glucose rise from a meal, and that walking helps most when it starts soon after the meal rather than much later or before eating. Other pooled analyses found the same for short, light walking breaks during long periods of sitting.
Muscles take up glucose when they contract, which is why even light movement helps.
How much activity do guidelines recommend?
- At least 150 minutes of moderate-intensity activity each week, such as 30 minutes on most days.
- Strength training about two times a week.
- Balance training two or three times a week.
Safety points to discuss with your care team
- Activity often lowers glucose. The NIDDK advises checking your glucose before, during and right after activity.
- If you take insulin or certain medicines, ask your team how to plan food and doses around activity. Do not change doses on your own.
- Choose footwear that protects your feet, and check your feet afterwards (daily foot checks).
Log it to see your own pattern
Write down the walk, how long it lasted and your readings before and after. Over a couple of weeks you can see what it does for you and show your care team. In Glycove you can say "walked 15 minutes after dinner" and it is saved with the time.
Information, not medical advice. Talk to your care team about your own targets and treatment. Never use a converter or a diary entry to work out an insulin or medicine dose.
