Are you talking about the US here? I'm pretty sure they've been around in Europe and the Middle East for centuries.
The "widening doorways" thing might be a bit too much unless the person in question actually has a medical condition though.
I can't imagine going from a sedentary, high-carb, overweight lifestyle to a radical diet(be it keto or whatever else the person chooses) is easy on the body.
Did you get any lab tests done before and after starting the diet? If you did, how did the results compare?

That may be true for the US market but Tesla is selling globally now. Trucks don't sell very well in Europe for example.
Edit: I'm not arguing for patents, but I don't think this particular argument in itself should be sufficient to dismiss a product's eligibility to get one.
