It's stored as new fat but there's something that you're missing - While
low carbing it takes a vast amount of extra dietary fat to force new
storage. While low carbing it's easy to eat fewer calories and lose
stored fat because there are neither carb cravings nor fat cravings.
While low carbing it is also easy to eat enough to not lose anything.
Calories do matter. While low carbing there are several reasons why it
is difficult to eat so much fat that new fat gets added to the body's
store.

If the amount eaten exceeds that which we can burn,
does the body package the extra in LDLs
and this shows up in the blood test?

If you are forcing new fat into storage your triglycerides will be high.

Reason one - While low carbing fat tends to turn off the appetite for
fat. This is something many find hard to believe so I recommand that
you try it some time.

First do it in your imagination. A stick of butter plus the same amount
of flour and sugar is a batch of cookies. Some of us might not be able
to stop if we start eating it. A stick of butter straight is a
completely different thought. Imagine eating a stick of butter
straight. Then imagine doing it daily for a week.

Next do it in actual practice. Figure out how many calories you have
for breakfast most days. Then find a type of liquid oil you find
pleasant and figure out how much volume it takes for that many calories.
For me it came out roughly a fluid ounce or a shot glass. Now drink
that as your breakfast each day. Nothing else just the oil so there's
no net change in your calories. Feel free to chase it with calorie free
liquid that is not sweetened in any way so you don't get the cookie
effect. When I did this I had a coffee. In my experience the first day
was fine. The second day I didn't look forward to it but I drank it.
As each day past my reaction got stronger and stronger. Within a week I
couldn't even swallow it by holding my nose.

It is really true that in the absence of carbs fat turns down the
appetite for fat. It's self limiting.

Reason two - While on a ketotic diet or other low carb system the
insulin level in the blood is low.

Insulin moves fat into storage. With low insulin there's no hormone
pushing fat into storage. it will not flow that direction without being
forced by an overdose, but that does not happen because of what I
described as reason one.

Glucagon moves fat out of storage. While eating low carb the higher the
percentage of dietary fat relative to dietary protein the higher the
glucagon level in the blood. Increasing dietary fat literalling
increases the pressure the hormonal pressure to move fat out of storage.

So what if you eat extra protein to mask the effect of fat to be able to
move it into storage? That's why every low carb plan out there mentions
portion control. You can do it, but on a properly executed low carb
plan there's no hunger so there's no physical drive to do it. It
becomes easy to decide to not overeat. That's one of the biggest
miracles of low carbing - There's no physical drive to overeat.
