With obesity and disease increasing dramatically, many fitness experts are
recommending walking for weight loss and fitness. Some are even going so far as
saying that walking is the best way to burn fat and lose weight. I strongly
disagree with this and am going to show you why walking is NOT effective at
burning off body fat.
Yes, you read that correctly...
Walking is NOT effective at burning body fat and if your goal is fat loss you
might be wasting your time. I am not saying that walking is not beneficial, I
am saying that if fat loss is the primary goal, there are far better choices
that will deliver far better results.
The primary benefits of walking are increased blood flow and circulation,
improved recovery, and a strengthened immune system. There are several reasons
why walking in not the best choice when it comes to fat loss. Here are just a
few:
1. Walking does NOT burn a lot of calories
The lower the intensity of the activity or exercise the smaller the number of
calories burned per unit of time. For example, you can burn more calories in 15
minutes of bicycling at a high intensity level than you can in 45 minutes of
easy walking.
2. Walking does NOT result in a large increase in metabolism
Another downside to walking is that because it's generally low intensity it
results in only a small increase in metabolism that will only last
approximately 1-2 hours after the walk. On the other hand, metabolism increases
are larger and last longer (4-24 hrs or more) when you perform high intensity
cardio workouts.
3. Walking does NOT deplete muscle glycogen
Low intensity exercise like walking does not deplete muscle glycogen levels and
therefore, later that day if you have excess calories they will likely be
stored as body fat whereas if you deplete the glycogen the excess calories will
primarily be stored in the muscles.
So why then do so many fitness and health experts recommend walking for weight
loss? One reason is that people don't want to hear that they have to work hard
so they figure some activity is better than none. Another reason is that the
body burns more fat for fuel when exercising at an easy pace, however, the
total amount of energy used is so small that you end up burning off little body
fat. That's also why when you choose the "fat burning" program on your
treadmill or bike it has you exercise at any easy level. Yes, you're burning
fat, but so little that you'd have to exercise at that easy pace for hours and
hours each day.
High intensity cardiovascular/aerobic exercise is much more effective in
burning off the excess body fat. In fact, several studies have been done to
prove this. In one study they compared one group who did moderate level
aerobics for 45 minutes with another group who performed high intensity
workouts for 15 minutes. They did before and after fitness testing including
body fat analysis and found that the group who performed the high intensity
aerobics lost nine times as much body fat!
Want more proof?
Compare the bodies of a walker, marathon runner, and sprinter. If you are not
familiar with what a sprinters body looks like, it is very muscular and has
little body fat while on the other hand the body of a walker will likely have
the opposite, little muscle and more fat. The sprinter does little or no low
intensity exercise and does primarily short hard bursts of work while the
marathoner overtrains so much they burn off both the body fat and the muscle
and that's why they tend to look almost sickly thin.
So what should you do then if your main objective is to shed those excess
pounds of body fat?
Two things:
1. Perform some form of high intensity cardio 2-4 times per week
2. Stabilize blood sugar to minimize the storage of new fat
I know some of you by now are saying "I can't do high intensity exercise, I
have a bad knee" and don't worry, I have a solution for you. The good news is
that high intensity is all relative to you and your current fitness level. For
example, fast walking up and down hills may be high intensity for you... it all
depends. So don't think that you have to start running or something like that.
Just slowly start to increase the intensity of your cardio workouts while also
maybe decreasing the time because you can either work hard or you can work long.
Also, you can make almost any activity or exercise high intensity.... here are
a few examples:
· increase your speed
· use an incline or hills
· increase resistance
· perform intervals ( the most effective method)
Obviously, some exercises/activities or better suited than others but the point
is if you want to burn more fat and make your workouts as productive as
possible you need to increase the intensity.

As with any changes to your fitness program be careful and don't over do it.
Just because high intensity workouts burn more fat, don't think that you'll get
even better results by doing it everyday - that will quickly lead to
over-training and a loss of muscle which will only make it even harder to burn
off the fat.
So if your primary goal is fat loss, don't waste your time walking and instead
focus on progressive, high intensity cardio to maximize the effectiveness of
your workouts.
