Are these LOW-CARB comments accurate?

Quoted message said:

LOW CARB IS NOT HEALTHY! YOU need carbs to fuel your muscle cells...
glucose stored as glycogen in the muscle cells is the first source of
energy the body uses during physical activity. think about this.. high
protein diets have benefits, but things that are high protein tend to
also be high in saturated fats like red meat, cheese, eggs, bacon... It
is awesome that you have dropped so much weight and all, but think what
your body is missing.... the brain can only use one source of simple
sugar- glucose.. which you need from fruits, veggies, and so on. also
carbs are the only macornutrient that contain fiber. you should aim for
25-30 grams / day to keep the body feeling full and the GI trac working
properly. I am an exercise science student.. please... head my advice..
complex carbs such as legumes, whole grains (oats, fiber one cereal),
vegetables, and fruits are GOOD for you!!!

From a scientific standpoint, that is. Are his comments accurate in

saying that the brain can only use GLUCOSE and that muscles need
GLYCOGEN in order to function? I have heard, although I don't know how
accurate it is, that if there is no GLYCOGEN present that you body can
still call upon "alternate" fuel sources to supplu your muscles.

Thanks

You can get enough glucose and glycogen from typically non carb foods
for these processes. Unless you are running 26 miles, then you may need
a bit more in your diet.

These so-called dangers are extremely overstated. There is no essential
carbohydrate. And a diet low in carbs still contains more than enough
carbs for these processes.

True.
There is no essential fat either, except for omega fatty acids, afaik.

More or less. Under conditions of starvation it can get some energy
from fat breakdown, but generally speaking the brain needs glucose
which is why there's glucose in the blood. (Most of) the rest of the
body runs quite happily on fat and only uses glucose when blood levels
get too high and insulin is released.

Quoted message said:

GLYCOGEN in order to function?

Muscles will run on fat or glucose until the demands are too great and
only glucose can be used. Most of the time there's glycogen in the
muscles, but all it is, is a store of glucose for when the blood supply
isn't enough (usually during prolonged intense exercise).

What whoever wrote it seems to be unaware of is that your body makes
glucose from protein. In fact about a fifth of your bodies energy needs
come from protein on a typical Western diet. If you eat more protein
and less carbohydrate in your diet the liver will just convert more
protein to glucose to keep blood levels where they should be.

There's also a big difference between "low carb" and "no carb" of
course.

You do not understand the term "essential" as it relates to nutrition.

From that web page:

"An essential nutrient is a nutrient required for normal body
functioning that can not be synthesized by the body. Categories of
essential nutrient include vitamins, dietary minerals, essential fatty
acids, phytochemicals and essential amino acids."

# Essential fatty acids:

* Linolenic acid (the shortest chain omega-3 fatty acid)
* gamma-linoleic acid (the shortest chain omega-6 fatty acid)

===

Only those omega FAs are considered strictly "essential". Not all fats
are.
That's just what I meant.

Great, two errors on the same line:

1) Wrong spelling: it's gamma-linolenic acid, not gamma-linoleic acid.

2) Gamma-linolenic acid is neither the shortest chain omega-6 fatty acid nor
an essential fatty acid, linoleic acid is.

But then it's Wikipedia, perhaps someone just introduced this error. Now,
could someone correct it?

seems to have at least this point right.

I was surprised that when I did a google search on "essential
nutrients" and it didn't find a simple list anywhere. I had to scroll
and click thru several pages of results to find that one with the
errors.

What does that say about the state of the science in nutrition?

What does it say about your research skills?

Did you consider googling up terms including human nutritional requirements?

When I did so months ago, it turned up biochemistry textbook chapters on it.

Not a thing. But it says a lot about your research skills.

If you include "human nutrition" in your search string, you get a
gazillion hits.

RE: is a low carb diet dangerous? Low carb is a subjective term. How
low is low? I do know that Atkins said in his book to go off his diet
for a week before having a glucose tolerance test because otherwise you
will test diabetic. Does that worry anyone?

100 grams of carb or less per day will induce ketosis.

Not at all, and I'm not quite sure you got that right.

I never saw that. Kindly provide a page number.

I don't remember the page, but I distinctly remember reading in his
book that there is a good chance that a person will NOT test diabetic.
