This is false.  Dietary fat can be stored as body fat.  It is
admittedly easier for this to happen in the presence of carbs,
since insulin governs the storage process.  But in non-diabetics,
insulin is never absent, even at low levels of carb intake, and
protein consumption causes insulin to rise, just as carb
consumption does.  Anyone who is eating enough protein to sustain
cellular integrity will have insulin levels adequate to store
fat.  But the protein also stimulates the production of glucagon,
as carbs do not, which tends to release the stored fat for fuel.

While ketogenic diets maximize the rate at which the body uses
fat, and minimize the rate at which it stores it, they don't make
the storage of caloric surplus fat as body fat impossible.
