Walking For Weight Loss: Does It Work?
The short answer is YES, walking does work for weight loss. But (and it's a big but), you need to do a LOT of it to see any real results.
Dr. Robert
Ross and a research team from Ontario, Canada, tracked 52 obese men for
three months. They split the men into four groups.
• Diet-only
• Exercise-only
• Exercise without weight loss
• No exercise or diet
Both the diet-only and exercise-only groups created a caloric deficit
of 700 calories daily. In other words, each day, the diet-only group ate
700 calories less than normal. The exercise-only group, on the
other hand, burned an extra 700 calories daily by walking on the
treadmill.
Three months later, the diet-only group had lost 11 pounds of fat and
four pounds of muscle. The exercise-only group lost 13 pounds of fat and
three pounds of muscle.
In other words, both groups got very similar results, although the walking group did lose a little more fat and slightly less muscle than the diet-only group.
Unfortunately, the exercise program involved 60 minutes of brisk walking
EVERY single day for three months. I don't know about you, but finding
the time to train for 60 minutes every day isn't easy.
The majority of studies examining the effect of aerobic exercise on weight
loss have used programs lasting 30-45 minutes, 4-5 days per week. Weight
loss with routines of this type usually averages about 0.2 pounds per
week (yes, the decimal point is in the right place!). Not much, is it?
So why are walking programs so ineffective at promoting weight loss (unless,
that is, you're prepared to invest around seven hours of your time each
and every week on the treadmill)?
Each
pound of fat contains roughly 3,500 calories. If we assume that 30 minutes
of brisk walking burns around 350 calories, it'll take AT LEAST 10 workouts
to get rid of just one pound of fat.
So if you do plan to use walking as
a way to lose weight, make sure you're aware that you'll need to do a
LOT of it to see real results.
