Sure....everyone needs sufficient water and low-carbers are no different.

Well, one thing about low-carbing is the loss of electrolytes like sodium,
potassium, and magnesium due to ketosis. So, when you're glycogen loaded
you won't have a deficiency in these and your muscles have glycogen, so you
can tap type 2 fibers more to enable you to go hard. On low carb, you're
deplete of all of these (electrolytes and gylcogen), so going hard will be,
er, hard. You can get muscle cramps and not have much of an attitude for
going hard. I think this occurs regards of how much water one drinks,
provided one has enough. I don't see what extra water will do if you're low
on electrolytes and gylcogen and that impairing exercise ability.
Your argument is that a LCer needs more water because water is lost in and
around muscles due to depleted glycogen stores. But just drinking more
water while LCing doesn't replenish that water - no matter how much you
drink. The water will just pass through.
The bottom line: I think one's water needs will be the same whether LCing or
not. Lyle's suggestion of 4 to 5 clear pees per day seems like the best
advice on water consumption. Electrolyte supplementation may be necessary,
however, for the LCing athlete.
As far as dieting goes, almost every diet book in existence recommends
drinking [censored] of water. It has been shown repeatedly that this
recommendation is baseless in fact. But if you have some citations
somewhere that says that LCers NEED more water because of restricted carbs,
please pass that on.
Just for the heck of it, though, i'm going to gorge on water before my
Thursday AM ride, which I will do while LCing (I've done this before, BTW).
I'm sure I'll be uncomfortable with a belly full of water while riding up
the first hill.
