Low-Carb Dieters Eat More Calories But... ---article about Low carb

Interesting article for low carb dieters. Short excerpt:

The study, directed by Penelope Greene of the Harvard School of Public
Health and presented at a meeting here this week of the American
Association for the Study of Obesity, found that people eating an
extra 300 calories a day on a very low-carb regimen lost just as much
during a 12-week study as those on a standard lowfat diet.

Over the course of the study, they consumed an extra 25,000 calories.
That should have added up to about seven pounds. But for some reason,
it did not.

"There does indeed seem to be something about a low-carb diet that
says you can eat more calories and lose a similar amount of weight,"
Greene said.

That strikes at one of the most revered beliefs in nutrition: A
calorie is a calorie is a calorie. It does not matter whether they
come from bacon or mashed potatoes; they all go on the waistline in
just the same way.

Not even Greene says this settles the case, but some at the meeting
found her report fascinating.

"A lot of our assumptions about a calorie is a calorie are being
challenged," said Marlene Schwartz of Yale. "As scientists, we need to
be open-minded."

Others, though, found the data hard to swallow.

"It doesn't make sense, does it?" said Barbara Rolls of Pennsylvania
State University. "It violates the laws of thermodynamics. No one has
ever found any miraculous metabolic effects."

I am curious if it occurred to any people here that the human
digestive process is more complicated than that of a furnace.

I am curious to know if a furnace has a disgestive process

Mine has an electrostatic filter on it, so it occasionally eats a bug
or two.

By using the calorie method, the human digestive process gets reduced
to being that of a furnace, with no understanding given to how the
biochemical processes work, or how the human body responses to
different types and quantities of food. Aspects such as the change in
metabolism are totally discounted.

This being said, I will say that the calorie DOES loosely map to
reality, and I don't know if there is a quicker and easier rough
measure for tracking weight loss.

That is funny -- and exactly what went through my mind -- except that I
thought of a gasoline engine!

It also depends on your own personal culture of gut flora and fauna.
There's quite a bit of evidence that stuff like the ability to
digest legumes efficiently depends on your intestinal microbes. If
legumes are a regular part of your diet and you have the right
microbes, the beans are digested easily with little or no flatulence
(no more than any other food). If you only eat legumes occasionally
(or only one type of legume) and you don't have the right microbes,
the legumes take longer to digest and produce a lot of side effects
(usually flatulence but sometimes diarrhea as well).

One interesting thing I learned: mice and rats that are bred and
maintained so that they have no intestinal flora and fauna require
30% more calories to maintain their weight than normal mice and
rats. But they also have a much higher premature mortality rate
because they tend to become ill much more easily than normal mice
and rats. Like so many things in biology, it's a trade-off.

And then there's the whole world of bacteriophages, which are
viruses that target bacteria. Staph bacteria are everywhere, for
example. Most of them cause no problems. Some of them tend to cause
skin lesions. And some of them cause rapidly moving gangrene! Which
type a given person has depends on which bacteriophages are acting
on those staph bacteria. Very, very little is known about
bacteriophages and yet they are the most common type of organism in
the human body. Ninety percent of the cells in the human body are
actually those of the flora and fauna we all have and bacteriophages
outnumber that flora and fauna by a factor of about one hundred.

Biology is such an interesting world! I only wish I could have a
second life so I could study it seriously.
