Doesn't literally any diet that induces ketogenesis qualify as "a keto diet"? Or, has somebody branded some particular ketogenesis-inducing diet "THE keto diet"?

I'm vaguely aware of some non-epileptics trying to induce ketogenesis in order to lose weight (which seems pretty dangerous, and maybe self-defeating since smelling like turpentine is less attractive than having curves), but real ketogenic diets (as recommended by medical professionals for intractable epilepsy) generally contain plants.
