Fitness - Inside the Body of a Non-Exerciser
If you don't
exercise,
this is
what happens
to your
insides.
Since your
body is
in a state
of rest,
the energy
produced
by breathing
is primarily
directed
to your
internal
organs-one
of which
is the digestive
system.
In this
state, 80
percent
of the oxygen-rich
blood is
flowing
to these
organs.
That leaves
only 20
per cent
for your
skeletal
muscles-which
are undemanding
because
they are
not being
exercised.
Your digestive
system signals
its hunger
pangs to
your appestat
- the brain
centre that
controls
the appetite.
This is
the time
you feel
hungry.
And as long
as you do
not exercise,
you continue
to feel
hungry at
regular
intervals.
When you
exercise...
Now, see
what happens
when you
exercise.
There is
a shift.
The energy
produced
now shifts
away from
your internal
organs -
including
the digestive
system.
|
If you
are working
out at
your optimum
aerobic
level,
80 per
cent of
your blood
supply
flows
to the
skeletal
muscles.
They need
that oxygen-rich
blood
to saturate
themselves
to go
about
their
business
of burning
fat for
more energy.
As the
blood
flow shifts
to these
muscle
groups
to provide
them with
the required
energy,
it is
the digestive
system
that is
passive.
Since
it is
in an
inactive
state,
it does
not demand
energy.
It does
not signal
to your
appestat.
Receiving
no signals,
your appestat
remains
silent.
So, you
do not
feel hungry.
There
is one
more advantage.
After
you have
stopped
exercising
for the
day, the
muscles
do not
stop their
activity.
Nature
has designed
them for
action
and they
continue
at their
pace for
another
hour or
more.
Which
means
for this
period
after
exercising,
the blood
supply
is still
being
directed
towards
them for
energy
and not
to the
digestive
system.
As a result,
for the
next hour
or more,
your digestive
system
is in
no state
to take
on food.
People
who are
into fitness,
experience
this wonderful
phenomenon.
Since
aerobic
workouts
use up
the water
in your
body,
this is
the ideal
time to
feed it
lightly,
with liquids.
By the
time the
digestive
system
gets back
its blood
supply,
it is
'full'
on the
liquid
meal and
does not
call up
the appestat.
The result
is that
you still
do not
feel hungry.
We hope
this explanation
lays to
rest the
myth that
exercising
increases
the appetite.
On the
contrary,
as you
have seen,
It reduces
your appetite.
This also
explains
why obese
people
feel hungry
all the
time.
