See how long you can hold your breath. Now go on a ketogenic diet, and measure your breath-holding ability again after a few weeks.

I haven't looked at your link yet but I remember seeing something before about some Navy divers using Keto. It was very interesting info.

Yeah, Navy SEALs. High-altitude athletes also give anecdotes about easier breathing. I wonder if any Everest climbers have tried it yet.
