Weight Loss
Water:
A sign that your body has enough water is the feeling that you are
having to force water down in order to meet a certain quota. It is
important to drink water when you are thirsty, but it isn’t
necessary to drink 8-8oz. glasses or water a day if you aren’t
exercising or sweating a lot.

Elizabeth Cohen, How much water do we really need? May 24, 2002 Posted:

“Well, if you're not sweating a lot during your show (the day),
then you probably don't need quite as much water as you think you
do. This eight eight-ounce glasses a day it turns out, after talking
to the USDA, the National Academy of Sciences, the National Institutes
of Health, people at various universities, they say, you know
what, this appears to be kind of a myth. We can't find a single study
that says that that's what people ought to do.”
"After 10 months of careful searching I have found no scientific
evidence that supports '8x8' (drinking 8, 8 ounce glasses of water
daily)," “there is no scientific evidence to back up this
advice, which has helped create a huge market for bottled water.”

”… the National Academy of Sciences has put together a
panel of experts to do nothing but look at how much water do we need.”(Current
study, results due in March 2003)
To replace daily losses of water, an average-sized adult with healthy
kidneys sitting in a temperate climate needs no more than one liter
[One liter is the equivalent of about four 8-ounce glasses] of fluid,
according to Jurgen Schnermann, a kidney physiologist at the National
Institutes of Health. Reference: Jurgen Schnermann, a kidney physiologist

EFAs are thought to lead to weight loss because of their ability to
stimulate thermogenesis (1). Thermogenesis is the process by
which the body can "waste" calories. A number of clinical
trials with obese patients have demonstrated that EFA supplementation
is an effective weight loss prescription (2, 3).
