I don't see the point in "you must drink 8 glasses of *pure* water per
day" rule, because you can drink additionally any other lo-carb beverage
if you're at the end of the day meeting that 8 glasses requirement of
pure water.

So let's say I drink 8 glasses of water and in the meantime I drink two
glasses of strong tea. The stomach is one and only one, so all this
water and tea gets mixed up and at the end in there and it's the same
like drinking 10 glasses of strong tea mixed 2:8 with water creating
some sort of weak tea taste. Which still tastes better than pure water!

But drinking this mix is not correct, according to the "pure water" rule
followers...
They would say:
You *must* drink 8 glasses of pure water on top of those mixed glasses!

Absurd?

You be the judge... suggestions?



At the end of the day you must have consumed a total of 8 glasses of
pure
water. It does not matter in this definition if you drank 30 glasses of
"fluid" that is only 26.7% water (the rest being whatever).

As for the diuretic effect of the impurities in the water, that is a
different matter.

In any event, dilute your tea by 1/2 with pure water and drink 16 cups
of
this mixture. You will be doing better in any event.

Myself, being a physicist, would rather be pedantic on the saying "not
all
calories are equal". All calories are equal.
A calorie is defined as the amount of heat (energy) required to heat one
gram of water by one degree Celsius (at STP as initial conditions).
What is called a calorie in the context of diet is actually a
kilocalorie.

In any event, all calories are the same because they are defined.

The more appropriate way to state the idea trying to be presented is
that
not all caloric sources are the same.

Of course, all the calories in food are the same thing since they're
measurements. But not all food sources will be used the same way and
not all foods are actually available for caloric use. Forgive me if
this is what you're saying and I'm not getting it.

You are, and that is the point of my pedantry.

An obvious example of non-caloric calories is fiber. Stick it into a
bomb calorimeter and you get a number around 4 Kcalories per gram. But
since our bodies can't digest and use that fiber, it's a package of
calories not available to us. In effect, non-caloric to human
digestion even though containing those pedantic calories mentioned above.
