If Excess Protein Turns into Fat...

Then how come the body can't use stored fat when it needs protein?
What, biochemically speaking, prevents it from turning fat back into
protein the way it apparently turns fat back into sugar? (I'm
assuming that 'cause stored fat is used for energy, right? And the
only form of energy for the body is sugar....)

And why doesn't the body use stored fat for its daily fat needs -- why
are people trying to lose fat still advised to get ("good") fats in
their daily diet??

Um, uh.

Excess protein becomes glucose. The liver does it.

Sugar is not the only form of energy for the body. Ketones are a big one,
if you don't guzzle carbs. Alcohol, I think, can too.

The body does not need to use stored fats, if the diet has too many
calories.

There are entire books saying that each kind of fat is the best fat, and all
the books contradict each other. Most agree that trans fats are bad.
Personally, I like saturated fats as found in Coconuts, and I suspect there
is merit to the form of Omega 6 called CLA. Without dietary fat, the body
makes its own fats. I have wondered if dietary fat is healthier than the
fat the body can make.

Fats don't contain amino acids which are necessary for the body to
synthesize proteins.

Fatty acids supply energy as well as glucose.

Stored fat is used for daily energy needs, however, excess calories
cause more fat to be stored.

PUFA, mega 6 and omega 3 fatty acids, are essential for normal body
metabolism and brain function.

Saturated fats don't have any well known benefit to the human diet,
and are suspected of contributing to cardiovascular disease and type
II diabetes.

The short answer is nitrogen. There's no nitrogen in fats. The
nitrogen is wizzed out as urea after the decomposition of protein.

The longer, but not longest, answer
1. There are 20 amino acids in protein. Each one has a different
pathway by which it is converted into fats or sugars and waste
products.
2. We can make some of those amino acids, but we lack the metabolic
pathways to make some of the 20. If one vital amino acid is missing,
you can't make any protein. This is why you can't live on a corn diet
(no lysine) but you can live on corn, rice and beans.
3. It takes a huge amount of energy to make protein, but you don't get
much of it back when you destroy it for energy. This is why you can't
live on lean spring rabbits.

No, the body can burn fat directly, but it needs some sugar to do
that. In other words, it can burn sugar only, and sugar plus fat, but
not fat only. The 'Atkins diet', where you limit sugars in the diet,
supposedly causes you to stop burning fat, too.

'Good' fats are usually not used for energy. They're used for
structure, cell membranes, etc. Bad fats aren't bad, either,
especially if you work very hard in a cold climate. Only fat can give
you enough energy. It's all in the amount you eat.

In the winter, polar bears hunting on the ice will eat only the
blubber of seals, leaving the meat and bones to the wolves who follow
the bears, and then what the wolves don't eat is taken by the foxes,
who have been following the wolves, who have been following the
bears.

False, Ron. Did you not see my post of a couple of days ago. I
examined the original experiments, and it was vitamin B6 deficiency.
When they fed the rats B6 but no fat, the rats were fine. They made
Mead acid, and in other studies, actually lived longer than the rats
fed "essential fatty acids." If you don't believe me, you are free to
take me up on the experimental offer I've made to you time and time
again. Stop spreading these very dangerous myths - you might hurt
someone badly. And how can I see all kinds of benefits, and no
problems, after deciding to avoid dietary PUFA since 2001? Do you or
do you not understand what a direct refutation is in science, and what
role it plays in the scientific method?

You can see relevant citations and quotations on the threads with
titles that are obviously on point (e.g., "Mead acid studies").

Incorrect: glucose can be created from fats using the gluconeogenesis
pathway and getting the energy for this pathway from the citric acid
cycle that the catabolism of fat feeds into.

You need to get your head out of your ass and read a bit more. Yes, PUFAs
are high in all the essential fatty acids, but there are MANY types of
saturated fats and not all lead to any cardiovascular problems. I'll bet you
an arm and a leg that you are a fat ass.

That is completely wrong. I am NOT a fan of ketogenic diets, but to say one
can't burn fat on them is just incorrect.

I'm guessing all these clue less people are not from MFW.
