I am always serious.
Quoted message said:It does happen and it has happened and it has been seen
in studies.
No, it has not.
If you refuse to accept the realisty in front of your eyes
, then it is no use pursuing this discussion.
What reality? What are you seeing that no-one else but you
is?
Quoted message said:Quoted message said:Quoted message said:It is not creating energy from nothing. No one has
suggested this.
If you eat less than you burn, and you are not burning
fat, then the only way to remain alive is to create
energy from nothing ... which is impossible.
This is why people starve.
If the energy values for food (ie. calorie value) are
incorrect or if they are not a static value (ie. the body
can extraxt more or less than the estimated 4 kcal of
energy from a gram of carb or protein, or 9 kcal from fats)
then it is impossible to correctly estimate the calories
needed or the calories extracted from the food, therefore
the calorie calculation proposed to estimate weight gain or
loss are way to fluid to be accurate.
At last, the penny drops. And there you were running around
with a calorie counter book and a bathroom scale screaming
"Eureka!" and claiming some new principle. The only way to
show the conservation of energy in the human body is in a
metabolic lab. Now make with the evidence for your claimed
new theory or stfu.
Quoted message said:No energy is created from nothing and no energy is lost.
At last. So you can now explain where every last
calorie goes to?
Quoted message said:Only the efficiency of nutrient and energy extraction from
the foods varies.
So describe exactly what happens. Are you now admitting that
your claims that a hypocaloric diet can result in weight
gain (fat store) is due to inaccurate estimations?
Quoted message said:Quoted message said:Quoted message said:The argument is that proteins and carbs are not always
metabolized to the 4 kcal/gram and fats are not always
metabolized to produce the 9 kcal/gram.
7 kcal/gram for fat. The numbers are adjusted to account
for their real influence in weight loss or gain.
Yeah, but are the adjustments correct?
No, still estimations in many cases. A good metabolic lab
study will be much more accurate and show that what you
claim is just an artifact of the poor experimental design.
Quoted message said:Are they correct in all states that the body experiences
from hour to hour. (ie. hormonal states, hunger states,
satiated states, states of hydration, etc).
Please learn some basic physiology. Look, the observed
anomalies are experimental errors. THERE IS NO HORMONAL
EFFECT ON ENERGY BALANCE. It is all supply and demand!
Quoted message said:That is the question. So far no-one has shown any concrete
scientific evidence that shows that the caloric values were
ever validated in studies.
[censored]. You are back on the roundabout. Calorie counters
are rough estimates. Foods vary widely in just the
constituents, and then the body extracts only roughly
estimated percentages of these from the foods. Then the
exercise taken is only a rough estimate. The principle is
always sound (when measured properly) but the measurements
are difficult to be any more than estimations.
Quoted message said:Quoted message said:Quoted message said:Ergo, one cannot use calories to predict weight/fat
gain or loss.
It works perfectly, so obviously one _can_ use them in
this way.
If it did, anyone who wanted to lose weight would.
And anyone who can manage a hypocaloric diet always will.
Quoted message said:Only those people who did not restrict calories would
be obese.
And they are. ALWAYS!
Quoted message said:Anyone could easily lose weight.
If they find reducing calories to a hypocaloric diet
easy. Many folks don't, hence the high failure rate.
Compliance problems.
Quoted message said:Low-fat and low-calorie foods are in abundance. But that
isn't the case is it?
They eat more calories than they burn. Simple. If you eat
four times a food that contains half the calories, you are
still getting twice the calories. Lo cal foods are not
magic, sorry.
Quoted message said:Quoted message said:Quoted message said:No I am not arguing against the laws of thermo. It may
be more accurate to apply the laws of thermo in terms
of the extreme ranges of energy usage but not to
predict weight loss or gain within the mid-range of
nutritional consumption.
The mid-range is not exempt from the laws of
thermodynamics.
That is not what I said. I said that we may be able to
apply the laws of thermo to predict the most fat storage
possible with the number of calories, or we can predict the
most weight loss possible with a minimal amount of
calories. What I am saying is that in the mid-ranges of
calorie consumption, it is not the basic number of calories
that trigger fat storage or usage.
But it is. If however your measurements are poor, you will
be working in the dark. A state which you appear to be very
used to 🙂
Quoted message said:What triggers fat storage are hormones that are affect by
multiple factors independntly of calories except for the
min-max as indicated above.
Where do you get this strange notion of hormonal
triggering. Look, storage is triggered by excess energy in
the bloodstream over that which is needed. Fat store
utilisation is triggered by need for energy in the
bloodstream. It is so simple.
Quoted message said:Quoted message said:Quoted message said:For instance, one may agree that one will never put on
more weight than is available in calories consumed or
that, conversely, a higher consumption of calories
makes available more energy/food for conversion to fat.
But the actual triggers to the creation and storage of
fats are regulated by the body by hormonal states
affected by the type of foods consumed and amount of
lean body mass, etc. No-one is suggesting that energy
disappears, it just goes thru the system or is used for
processes other than creation of fat stores. No one is
suggesting that energy is created to created to store
fats either, in the case of someone gaining weight on a
lower calories diet. It is being suggested that when
the hormones trigger fat storage the body will use the
available glucose to create the lipids at the expense
of the other processes such as tissue re-building or
cell energy.
It is possible to eat more than one burns and not gain
weight, if the added calories are excreted. However, it
is never possible to eat less than one burns _without
losing weight_. That is a physical impossibility.
You are assuming that the 4 cal/g for protein and carbs
and the 9 cal/grams for fat hold in every instance
therfore this weight gain or loss is predictable. That is
where we differ.
Those numbers are only approximations. Please do some
reading. Didn't you post a good historical description of
the estimating of food energy contents? A met lab study can
feed foods of exactly known energy content. These will be
totally absorbed, as well. Calorie books and a kitchen scale
are very rough. Studies which don't accurately measure ALL
inputs and outputs are useless.
Quoted message said:Quoted message said:So fat people who claim that they eat less than they burn
and still fail to lose weight are either having trouble
with arithmetic or lying.
No one claims that they eat less than they burn.
Huh? They are doing it all the time.
Quoted message said:They claim that they eat less calories and they still fail
to lose weight,
Less than what? Less than four times what they need?
Three times?
Quoted message said:or they may actually gain weight on fewer calories.
See above.
Quoted message said:You view this as being counter to the laws of thermo and
thus impossible.
I think you are confused about what they claim.
Quoted message said:I see it as being counter to the belief that the caloric
value assigned to foods are static in all circumstances,
which is not only possible but it is probable.
Foods have an actual calorie content. Sometimes finding this
with any degree of accuracy is problematic with tables and
scales. Nevertheless, it will be an exact number. It doesn't
vary. What may vary is the proportion of a food that is
actually absorbed into the body. This amount is what we are
talking about, not the amount we put into the tube that goes
through our bodies.
