The simple reason why is because it involves running, and running is a fantastic way to burn calories and lose weight.
However, that's where the similarities end because indoor running on a treadmill is quite different to outdoor running both physically and mentally as well as how it can fit in with your lifestyle.
Three reasons in particular why using a treadmill can help you to lose weight when compared to outdoor running are:
1. Greater flexibility and consistency
You can train at home or in the gym, and in all weather conditions so there are no excuses to miss a run.
No matter what the weather is like, whether it's hot, cold, wet, or windy, you can always jump on your treadmill and complete nearly any run that you could have done outdoors.
This can help you to keep running consistently and keep losing weight rather than being put off by poor weather conditions.
2. More distractions
Some people like to concentrate on exactly how their body feels and how well they're performing during a run whereas other people feel better when they are distracted and can "cut off" from the difficulty of running.
With a treadmill, whether you're at home or in the gym, you can watch television or listen to music or the radio which can help take your mind off the running.
Depending on your personality this could make running seem easier which means that you can end up running longer or faster and therefore burn more calories than you would have without the distraction.
3. Less intimidation
Some beginner runners prefer to use a treadmill and run indoors because they feel self conscious about people seeing them running outside.
This means they can start running and take advantage of its excellent weight loss and health benefits whereas maybe they wouldn't have if treadmills weren't available.
There's no need to feel self conscious about running outside but even if you do a treadmill can help to build confidence and reduce any intimidation that you feel. Maybe you'll progress to outdoor running in the future?
Just remember that you're trying to make a huge difference to your life by losing weight so try not to worry about what other people think.
You can also feel good and confident in the knowledge that by using running to lose weight you can quickly become much fitter than most other people, regardless of your weight.
So which is the best for losing weight: treadmill running or outdoor running?
In the end it all comes down to your personal preference. They are both excellent ways to lose weight, and most of the running methods that can be done outside can also be used on a treadmill.
So now there's no need to wonder about "Will the treadmill help me to lose weight?" because you know for sure that it will. It's more a case of whether a treadmill is right for you.
