Pat:
I thought I addressed the normal person in the next
paragraph:
....
an unconditioned person is unable to develop more than about four times
his/her normal, day-time power. Energy measurements reveal that an average
person performing only the necessary daily activities expends 8000 kJ in the 60
ks of the non-sleeping time. This represents an average power of 8000/60
@
130 W. The unconditioned person's
maximum power is therefore limited to 4x130 = 520 W. ....
That is why a lot of sweat
produces little lasting mass loss in sedentary people. Now, you and me do
some walking (I snow-ski instruct) and so can perform at a higher lever. Keeping
mass down is easier for us. This is just a thermodynamic explanation.
Feeling good about oneself is another matter - see the numerous happy Buddhas
around.
Personally, I am disgusted
with the obesity prevalent everywhere in the US. The overburdened emergency
rooms and health care in general causes the skyrocketing costs per capita. On
well, sorry. Non-metric subject.
Have a happy New Year and if
you are in the neighborhood, we'll go for a hike in the Berkshires.
Strenuous on our scale.

Resolutions
Dear
Stan,
Thanks for the reference to your article. However, I would like
to compare your top athlete to a more normal person. You
say:
The world of energy
measurements tells us that a top athlete can expend at most 1750 kJ
exercising for 1 ks (a quarter hour). From these numbers, the top athlete's
power is 1750 kJ/ks = 1750 W. Our overeater's power would have had to be
2000 kJ/ks = 2000 W. This means that our overeater needed to exercise harder
than a top athlete could to dispose of the excess food.
But I would argue that we are discussing not a top
athlete but an ordinary, slightly sedentary, and probably obese person such as
myself.
In the instance below, I will use the example of a man of
average height (1.75 metres) who has a body mass of 95 kilograms that is his
Body Mass Index is 31 and he is just inside the obese range as judged by his
BMI.
This man might do nothing, and, as you say, with ageing his BMI
would gradually increase. However, if he found ways to go for short walks
until he regularly walked briskly for 20 minutes each day, he would use an
additional 450 kilojoules of energy each day that he would not otherwise have
used.
Although he does not expend energy at the power rating of your
top athlete my sedentary and obese person is using more energy than
previously and gaining many other benefits from his exercise. If his diet
remained the same as it was then he might, at least, avoid the increase due to
ageing in his Body Mass Index and might well begin to lose body mass because
of the increase in muscle cells he builds up through his walking program.
See:
http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Metabolism_explained?OpenDocument
for sources of data for this calculation.
I am, however, convinced
that he will feel much better for the other benefits of his walking program.
The real issue, worldwide, is how to encourage people to take up additional
activities such as walking. My article, Walking for fitness at http://metricationmatters.com/articles
was intended to encourage others to begin a walking program in a way that was
simple and approachable.
You and I both know that this is a serious
matter. Only about 1 in 10 of adults in Australia or the USA have a regular
exercise program of any kind, and that this issue is causing serious health
issues in both of our nations, such as the heart conditions and diabetes
associated with obesity.

Pat provides lots
of hints for a casual mass-loss. Before you get too excited about the ease,
read the attached. It was published some years ago in a monthly. The
manuscript is intended to just present the facts; by no means it should
discourage exercise. The opposite ! - make you work harder, starve more, and
be happy at it by knowing that both are necessary.

Subject: [USMA:35500] New Year's
Resolutions
Dear All,
As many of you
will be about to commit yourselves to this years crop of new years
resolutions, and I am thinking that some of these might include
things like:
I must become fitter or
I should lose
some of my body mass to get my Body Mass Index (BMI) back into the
normal range,
I have just finished writing (for myself
because I need it) a metric guide to getting fit and losing body
mass called:
Walking for fitness
I hope
that you, too, might find it useful.
You can find Walking
for fitness as a pdf document at http://metricationmatters.com/articles
It is at the bottom of the page.
Cheers and best wishes
for your fitter and lighter new year,
