I am not into Keto diets etc but have no problem riding a metric century on just water. I wouldn't be able to push hard for long but if the pace is kept moderate it isn't a problem.
That's kind of a big issue.
That's why I don't get why anyone would even think of trying this to get faster, or would try to ride 60+ miles on "just water". Averaging ~276 watts an hour is ~1,000 kJ, and that's not even a lot of watts relatively speaking. You need some carbs if you want to actually ride fast.
