Ah. At this point you've finally come out as a no-carb troll.
History says no-carb trolls don't last so you're not a problem.

And there is only two things that make the pancreas
secrete and release insulin, it's carbohydrates and protein. But there's
only one of those that causes fat to accumulate, it's carbohydrates.

This is incorrect. It's only carbs. See glucogenesis for how
excess protein is converted to glucose for use as fuel.

The mechanism is complicated and even I don't know everything that goes
on but I'll try to explain it in the simplest terms I can.

The mechanism is only complicated to people who want it to be
as simple as "if low carb is good, then lower carb is better and
zero carb is best". If it were that simple every single low carb
book out there would recommend doing exactly that. None do
and without exception folks who draw out quotes on the topic
to support that view ignore the context from the book they are
quoting.

Below some point in dietary carbs eating less carb does not
result in lower insulin release. Lower isn't better all the way to
zero.

Protein doesn't cause glucose to rise

Incorrect. See glucogenesis for how excess dietary protein is
converted to glucose at a bit over 50% energy efficiency.

... However,
in the context of a low carb diet, eating protein can cause a stall in
fat loss temporarily because it causes insulin to rise temporarily. The
solution to this is easy, eat less protein but eat more fat.

Also incorrect. This ignores the fact that fat is pulled from storage
based on the concentration of the hormone glucagon and that
glucagon is released in an indirect result of (dietary fat calories
minus dietary carb calories) and that's why low carbing is high
fat.
