Not sure how much of this advice is a requirement for survival. I know
I
recommend to those on low carb to drink lots of water, but for a
different
reason. When low carbing you are often in ketosis. Once ketosis
reaches
a high enough level you stop burning fat. By drinking more water you
get
rid of extra ketones and continue to burn fat. The other reason is
that
you often don't feel thirsty and may drink less than you really need
to.
I personally take extra supplements and water helps me get rid of
those
I don't need.
