Walking After Meals: A Simple Habit for Steadier Energy

You finish dinner, sink into the couch, and an hour later you feel flat and ready for bed at 8pm. Sound familiar?

One habit costs nothing and needs no gym: a short walk after you eat. Here's what the research says.

Why meals can leave you feeling sluggish

After a meal, the sugar in your blood naturally rises and then settles. That's normal. But big meals and long stretches of sitting can make that rise bigger and slower to settle. Many of us eat our largest meal at night, then sit for the rest of the evening.

What the research says about a walk after eating

A meta-analysis of eight trials found that exercising after a meal lowered the rise in blood sugar compared with resting, while exercising before the meal made no clear difference (Engeroff, Groneberg and Wilke, 2023).

In a New Zealand study of adults with type 2 diabetes, a 10-minute walk after each main meal led to a lower rise in blood sugar than one 30-minute walk at another time, especially after the evening meal (Reynolds et al., 2016).

In a small study of inactive people aged 60 and over, three 15-minute walks after meals lowered blood sugar after dinner more than one 45-minute morning walk (DiPietro et al., 2013).

In postmenopausal women, breaking up sitting with five minutes of standing or light walking every 30 minutes lowered the rise in blood sugar after meals (Henson et al., 2016).

These studies were small and short, but together they point to a simple, low-risk habit worth trying.

Easy ways to move more around meals

• Start with 10 minutes. A gentle walk around the block is plenty.
• Prioritise dinner. If you can manage only one walk, make it after the evening meal.
• Go soon after eating. Aim to head out within about 30 minutes.
• Keep it easy. A pace where you can still chat is fine.
• Break up sitting. Stand or move for a few minutes every half hour.
• Make it social. Walk the dog or invite the family along.
• Have a rainy-day backup. Walk laps of the house or climb the stairs.

What popular health podcasters say

On the Huberman Lab podcast, Andrew Huberman and his guest discussed walking and frequent light movement, including a short walk after meals, as everyday tools for steadier blood sugar (Huberman, 2024). On The Tim Ferriss Show, guest Dr Martin Gibala described “exercise snacks”, such as a few flights of stairs spread through the day (Ferriss, 2018). Both ideas line up with the research above. Podcasts can be a great source of ideas, but they're no substitute for advice tailored to you.

When to see a professional

Feeling sleepy after a big meal is common. But see your GP or a qualified health professional if you notice:

• tiredness that doesn't lift, even with good sleep
• strong thirst, needing to wee often, or unexplained weight loss
• blurred vision
• feeling shaky, sweaty or faint after eating
• chest pain, unusual breathlessness or dizziness when you walk.

If you have a heart, lung, joint or other health condition, check with your doctor before starting a new exercise routine.

Frequently asked questions

How long should I walk after eating?

Around 10 minutes is a great start. Studies have used walks of about 10 to 15 minutes after meals.

Does it matter how fast I walk?

Not much. Most studies used light to moderate walking, so a comfortable pace is enough.

Is walking after dinner better than walking in the morning?

Any walking is good for you. Some studies found a walk after dinner had a bigger effect on blood sugar after that meal than a longer walk earlier in the day.
