Maybe, As the snip below shows, the percentage of fat in the study is not
unlike the current mixed reccomended diet, and also recall that atkins
said to limit saturated fat to 20 percent:
"But, he said, the findings do indicate that moderation, and not tight
restriction, is the way to go. According to Pendergast, that means
getting about 30 to 35 percent of calories from fat -- at or slightly
more than the level health officials currently recommend.
But he also stressed the importance of calorie balance, which means
eating only enough to meet the body's calorie expenditure. Fat has
more calories per gram than either carbohydrates or protein, and if a
person takes in more calories as a result of eating more fat, weight
gain may follow."

I don't buy the "calories in vs. calories out" argument for one simple
reason: energy is not the only thing the body exchanges with its
outside. Not to mention that the way the caloric content of food is
measured in the lab may not result in the same amount inside the body.

Yes and no. There is still the fact that the Atkins diet only works
because protein brings about satiety, there is no actual metabolic
advantage at play-as Atkins always believed.

A BBC science programme called "Horizon" did an interesting study on
Atkins a few months back. The results proved that ketosis creates a tiny
metabolic advantage (a few calories) and that it was protein and not fat
causing satiety and thus resulting in people eating less. Atkins did a
lot of good things in fighting the low-cal mindset but he was
fundamentally wrong in his understanding of the biology behind the diet
he advocated. |

As I recall, the 'orthodox' scientists who did 'Horizon''s calorie
experiment using the sealed chamber with 'Atkins' and 'Non-Atkins' twins
inside them made an idiotic and self-serving error: they measured air
temperature changes in the chamber and the energy each twin excreted via his
urine *but failed to analyse the stool contents and measure the calories
excreted via that route*.
Also, they failed to 'cross over' the two twins so that the 'Atkins' one
then became the 'non-Atkins' one, and vice versa.
Incidentally, the established science of 'nutrition' has reason to be
thoroughly ashamed of its minimal level of achievement when the world
observes that it takes *a popular science TV programme* to try and find out
whether the 'satiety' experienced on Atkins is due to the protein or the
fat. Sheesh!

If you consult an article posted by another reader on this ng, one finds
that heat measurement might be all that is needed to a good approximation:
http://makeashorterlink.com/?L11221638
Energy expenditure for the whole organism is related to heat
production Energy consumptionheat production. Place a person in a box
that isolates him from the environment and measure his physiochemical
state (temperature, pressure, phases etc.). Then give him 2000
kcalories of glucose to eat. At the end of the 24 hrs you reassess his
composition. You find that that his physiochemical state is identical
to that prior to entering the box (he neither gained or lost weight).
You would also find he lost exactly 2000 kcalories of heat. If the
person did work in the box after eating 2000 kcal, our subject would
lose weight. If he was given 3000 kcal and he produced 2000 Kcal of
heat, he would gain weight. The pathway by which substrate is oxidized
does not influence the amount of heat (energy) that is released. So if
you first take glucose store it then release to be oxidized, the
energy released would be the same as if the glucose were immediately
oxidized. Thus energy released is independent of the pathway followed.
The energy released by catabolism of fats and carbohydrates is
identical to that released by ordinary combustion to carbon dioxide
and water. The values are expressed as Cal or kcal=1000 cal=amount of
heat necessary to raise the temperature of 1000 g water

I could have sworn I recently saw a study where people on Atkins who
had a 300 calorie surplus as compared to the non-Atkins group still
lost more weight than the non-Atkins group (I believe both groups were
on a weight loss regimen). I remember one of the authors of the study
being very surprised at this and not being able to offer an
explanation.
But I agree that calorie budget is the most important factor for
weight loss/mantenance, however macronutrient selection is also very
important for disease prevention in the long term. In my mind the
optimum diet for longevity is a lean meat + low starch veggies diet
which happens to resemble the Atkins diet.
I don't know if the media is to blame or Atkins himself for this
portrayal of the Atkins diet as consisting of slabs of greasy meat and
bacon sizzling in an inch of grease but that is unfortunate given the
number of people subscribing to the Atkins diet. It is at least
encouraging that people are thinking about nutrition to a greater
degree. Let's see if it lasts.

I went back to the article mentioned above, the urine was chosen because
Atkins speculated that extra energy might be excreted by it as metabolic
products of his induced metabolic state. There was a 1 percent
difference, statistically insignificant result. They were testing his
speculation.

I suspect that most 'media people' only take the trouble to look at the
somewhat more extreme 'induction diet' that the book presents first, and
draw unwarranted conclusions from it. You have to go *200 pages in* - more
than half of the book! - before you see what the diet involves in the
long-term...
If Atkins had started with a big chapter that outlined what dieters *would
eventually be eating* (on their 'Maintenance' diet, say), things might not
have gone quite so badly awry - though of course maliciously mendacious
misrepresentations of his diet would still be appearing.

I agree heat is important, but so is a "physical" calorie measurement. It is
an error to assume all caloric value is extracted prior to excretion. Why,
I've had friends that ate several meals and snacks a day -- they should have
been in a constant fever!

Hint: substantial excretion of macronutrients in the stool usually results
in diarrhea. |

Not a big deal. It is hard to find consistent source of saturated fat
that does not come with MUFA and PUFA.
That said, by eating fatty pork alone, saturated fat will acount for
about 30% of your calories intake. Add some veggies and perhaps some
vegetable oil and you have 20%.
So he did not said to "limit" sat fat intake, but 20% is what average
low-carber in initial phases of diet eats.

I have not seen the programme, but from what was posted here, that
experiment lasted only 2 weeks. In other studies, metabolic slowdown (or
speedup) appears to begin after three weeks on diet.

Well, I think he was great practitioner. I think too that many of his
"scientific" explanations were wrong.
OTOH, his process does seem to work very well.

what other things does the body exchange with the outside, that you think
are relevant to this? |
