The short answer: brisk walking is the example both the CDC and the NHS give for moderate-intensity activity, and it counts toward the weekly guidelines. Neither promises that walking will reduce belly fat, and research does not support the idea that exercise can target fat in one area.

Does Walking Reduce Belly Fat?
Can exercise target belly fat?
A 2022 systematic review with meta-analysis in Human Movement pooled 13 studies with 1,158 participants. It concluded that localized muscle training had no effect on localized fat depots, and that spot reduction was not observed.
Two limits are worth knowing. That review looked at training a specific muscle, not at walking in particular, and it is one review. We read its published abstract, not the full paper.
The CDC and NHS guidelines below do not describe a way to lose fat from the belly in particular either, so be cautious about websites that promise one.
What the guidelines recommend
The CDC says adults need at least 150 minutes of moderate-intensity physical activity a week, and gives brisk walking as an example. Its sample schedule is 30 minutes a day, 5 days a week. It also recommends muscle-strengthening activity that works all major muscle groups on 2 or more days a week.
The NHS guidance for adults aged 19 to 64 is similar: at least 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous activity, plus strengthening activities on at least 2 days a week. It suggests spreading activity evenly over 4 to 5 days a week, or every day.
The CDC adds that some physical activity is better than none. The NHS says exercise just once or twice a week can reduce the risk of heart disease or stroke.
What walking can do for you?
The CDC says physical activity supports physical and mental health, and the NHS links regular exercise with a lower risk of heart disease and stroke. Walking also has practical strengths of its own:
- It is a form of activity that counts toward the weekly guidelines.
- It needs no equipment and can be done in short blocks.
- It is a realistic habit for many people to keep up over months.
What to realistically expect
Treat walking as a habit that supports your overall health, not as a quick way to change your waist. If your waist changes over time, many things may be involved, including what you eat, how much you move overall and your age. If you track your waist, measure the same way each time and look at the trend over months.
Getting started
- Start with the time you can manage now, even 10 minutes.
- Build gradually toward the weekly amount in the guidelines, if that suits you.
- Add strengthening activity on 2 days a week when you are ready.
- If you have a health condition, are pregnant or are unsure what is safe for you, talk to a healthcare professional first.

Frequently asked questions
How much should I walk each week?
The CDC says adults need at least 150 minutes of moderate-intensity activity a week, and gives brisk walking as an example. The NHS gives the same amount for adults aged 19 to 64, or 75 minutes of vigorous activity.
Does brisk walking count as exercise?
Yes. Both the CDC and the NHS use brisk walking as an example of moderate-intensity activity.
Is it still worth walking just a few days a week?
Yes. The CDC says some physical activity is better than none, and the NHS says exercise once or twice a week can reduce the risk of heart disease or stroke. The NHS suggests spreading activity evenly over 4 to 5 days a week, or every day, if you can.
Can walking target belly fat?
Research does not support that idea. A 2022 meta-analysis of 13 studies found that training a specific muscle did not reduce the fat stored in that area. That review was about localized muscle training, not walking specifically, but neither the CDC nor the NHS describes a way to lose fat from one area.
Do I need strength training as well?
Both the CDC and the NHS recommend muscle-strengthening activity that works all major muscle groups on at least 2 days a week, in addition to aerobic activity.
