“There are a lot of benefits to walking after eating, or
post-prandial exercise,” says Juan Delgado, a sports scientist and certified biomechanist with New York’s Sports Science Lab. “It lowers glycemic index (https://pubmed.ncbi.nlm.nih.gov/19560716/) significantly, improves your intestinal movement,(https://pubmed.ncbi.nlm.nih.gov/18392240/) promotes better sleep,(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6112920/) and boosts your blood
flow.(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6267507/)”
1. Improves digestion: Once you’re done eating, your body gets to
work, and all of the different nutrients get broken down. “Proteins, electrolytes, water, vitamins, carbohydrates, and other nutrients are absorbed and transported through your body to wherever they’re needed,” says Delgado. “This process can be improved by walking after eating, as walking has been found to play a significant role in reducing gastric emptying time by reducing the time that food moves through the gastrointestinal tract, which results in faster digestion and less bloating after
eating.”
2. Improves blood sugar: Similar to promoting better digestion,
walking after eating helps regulate your blood sugar levels.
“After eating, food must be broken down into forms of energy for the body to use,” explains Feit. “Research has shown that as little as ten minutes of post-dinner walking can improve blood glucose levels compared to other times during the day.”
3. Decreases stress: Exercising in general makes your body release
endorphins, which are a feel-good chemical (that also happens to reduce stress).
4. Boosts blood flow: When you’re walking, you’re letting your body
pump more blood throughout it—which is especially beneficial after a meal. “Another important benefit of walking is better blood flow, which is essential for muscles,” says Delgado. “It induces blood flow to the limbs and organs, and better circulation due to movement will result in a healthier vascular system that will transport the nutrients necessary to bones, muscles, and organs to work more
efficiently.”

The study was carried out by researchers from the University of Otago in New Zealand.
The researchers included 41 adults with an average age of 60 years who had diabetes for an average of 10
years.
The study found that when participants walked after meals the level of blood glucose was 12% lower than in those who went for a single walk each
day.
The improvement was greatest after the evening meal, 22%, when carbohydrate consumption was generally highest. This is also the time of day when people were most likely to be active.
This randomised controlled crossover trial aimed to assess whether taking a 10 minute walk after each main meal provides additional benefit in lowering blood glucose in people with type 2
diabetes compared with a single 30 minute daily walk.
The study found that taking shorter, more frequent walks after meals produced lower blood sugar estimates than a single
walk.
