Usually people only have those issues when their bodies are first adapting. Once your body begins to get used to it, you don't have problems.
You mentioned hiking when keto-fueled. For pure aerobic exercise over a long distance, there's a decent argument to be made that it's better to be in ketosis, because your body is more easily hooked up to the "alternate tank of fuel" (your bodyfat) once the glycogen levels get low. It's not like shifting without a clutch and hitting the wall as one would likely do on a high-carb diet.
Glad you've found a system that works for you. Very healthy.
