I know my goal every day is 10,000 steps but I see drastic changes in my caloric burn depending on how I meet or exceed this goal. I was really curious as I see my challengers, friends, and family posting their daily steps and I wanted some clarification on the actual benefits. Sometimes I feel there is a false sense of accomplishment with these FitBit and Tracking devices, it is always good to know exactly what is going on and how you are or aren't benefiting. No-one wants to waste their time and energy without results but let's be honest, we all know when we are on target with our nutrition that we see changes but if we walk or run 3 miles and then eat crap your weight and health does not improve!
You can not out exercise a poor diet.......plain and simple. So here is some really great information on these 10,000 Step Goals!
10 years ago, if you had asked someone about how many steps people were supposed to get a day, you probably would have gotten a blank stare. But ask anyone today - whether they exercise or not - how many steps people should be getting a day and you’ll likely get, “10,000, of course. Everyone knows that."
But have you ever wondered why? What does taking 10,000 steps do for your body anyway? Is there really a point? Before we answer this in more detail, let’s make one thing perfectly clear: Walking more – or increasing your activity throughout the day – absolutely has positive health benefits. A 2010 study has shown that walking more has a whole host of positive health benefits, including improved cardiovascular health, personal growth, and many other variables that contribute towards healthy living.
Additionally, the American Heart Association notes that a brisk walk can lower risk of high blood pressure, high cholesterol, and diabetes if performed and maintained over time.
While there’s no doubt that it’s a good idea to walk more, the main reason driving people to move more - to lose weight/body fat - is where people can be misled. It's for this reason that a number of fitness wearables have built their entire value as being a vehicle that drives people to lose weight. Many of these have honed in on 10,000 steps as being the default goal that causes fat loss; some have even gone as far as to call 10,000 steps the “magical number.”
But how magical is 10,000 steps? Can taking 10,000 steps a day cause meaningful changes in your body composition and help you lose body fat?
Let’s find out.
There are a couple likely reasons why taking 10,000 steps has rooted so firmly in our minds. One is that 10,000 is a nice, round, easy-to-remember number. Another is that 10,000 steps has benefited from being so popular; its so widely known that people assume it must be a good goal for fat loss, otherwise, why all the buzz?
In order to achieve fat loss, you need to burn more calories than you get from your food. That’s called a caloric deficit. A general rule of thumb is that a pound of fat contains around 3,500 calories, and the logic goes if you create a caloric deficit of 500 calories over a 7-day period, that’s equal to 3,500 calories: good for a pound of weight loss per week.
It’s been claimed that individuals may be able to lose a pound of fat a week just by taking 10,000 steps because of the potential to burn 3,500 calories from walking. Unfortunately, this claim is a large over-generalization that applies to precious few people, and - unless you’re keeping careful watch of your calories in/out - likely doesn’t apply to you.
To understand why, it’s helpful to understand where the claim comes from. Unfortunately, it’s based on several rough estimations. For example,
- Weight
- Walking Speed and Distance
For a 160-pound person, a leisurely 30-minute walk at 2 mph yields a burn of 102 calories, but walk at a more upbeat pace (3.5 mph) and the calorie burn increases by 54% to 157 calories.
Why? Simple: the faster you walk, the more distance you're able to cover in the same amount of time. The sources that suggest you can burn 3,500 calories a week from walking typically assume you walk at the more upbeat pace to achieve the necessary distance.
So assuming you weigh 180 pounds and walk at the necessary intensity, then yes, by simple mathematics, 100 calories burned x 5 miles equals 500 calories, which if you maintain 7 days week becomes 3,500 calories.
If you deviate from either of the above conditions, your results may differ.
On top of all this is another pair of conditions, ones that are more significant and could make all the time you spend trying to reach 10,000 steps almost entirely irrelevant if you aren’t careful: weight loss from running assumes your weight is stable (your calories in equals your calories out).
You Can't Walk Away From Your Diet
There’s no doubt that walking more increases your activity levels, leading to more calories burned throughout the day. However, without a better idea about the state of your body’s energy balance, your walking 10,000 steps, 15,000 steps, or even 20,000 steps a day might not be enough to cause any meaningful fat loss or changes in body composition, even if 10,000 steps = 500 calories burned for you.
For example, let’s say that you need 1,800 calories a day to maintain your current body weight, but you actually eat 2,300 calories a day. Assuming your 10,000 steps equal 500 calories burned (which, as shown above, is far from guaranteed), you’d only be bringing yourself to a net caloric balance of zero, meaning the 10,000 steps you are taking are only helping you maintain your current weight and not lose fat.
Ex. Calories Burned a Day (1,800) + Calories Burned from 10,000 steps (500) = 2,300.
Calories eaten (2,300). Caloric balance occurs - no weight change.
Ex. Calories Burned a Day (1,800) + Calories Burned from 10,000 steps (500) = 2,300.
Calories eaten (1,800). Caloric deficit (-500) created - weight change occurs.
You can read up on how to learn what your BMR is and how to use it to get yourself into a caloric balance, but in a nutshell, here’s how:
- Get your body composition determined and get results for your Body Fat Percentage and Lean Body Mass.
- Convert your body composition results into your BMR. Some body composition analysis devices will automatically offer this on the result sheet. If yours doesn’t, you can use an online converter, like this one by IIFYM.
- Multiply your BMR by 1.2. This will give an estimate of how many calories your body needs to maintain its current weight, assuming you don’t do any extra exercise.
Depending on how great the difference is between your diet and your TDEE, taking 10,000 steps may not be enough to cause any change in your fat mass. If you’re overeating to begin with, 10,000 steps may be just enough to stop additional weight gain, but if you’re like most people, you probably don’t start new fitness programs and walk 10,000 steps just to maintain weight; you want to lose weight.
Also: if you catch yourself eating more because you're now more active (a pretty common urge), this also will sabotage your efforts.
You can’t out-walk your diet. If you’re hoping to burn pounds of fat by taking 10,000 steps a day, unless you’re doing a lot of things right already – like tracking your calories in – you may be walking for a long time.
