Not really. The keto diet includes plants. Just not starchy or sweet ones, e.g. cauliflower, lettuce, broccoli, etc.
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.
I dropped broccoli because of high carbs..
