Off the point you guys are making, but two things that may make some
people curious about weight fluctuation:

You give two examples of why it is a bad idea to get on the
scale more than once per day. Doing so very often tends to
be obsessive behavior with irrational motives because the time
scale for fat loss is month to month (not a single dieter in
history likes the fact but disliking a fact does not convert it
to fiction) - Getting on the scale more than once per day is
wishing for that which is physically impossible.

I often weight one pound less
between the time I go to sleep and the time I wake up even though I
did not visit the washroom.

I sweat while I sleep in addition to breathing. Sweat is
water and therefor not fat. Taking readings inside of a
single day can only tell me about water, food, liquid,
stuff moving through my bowels and so on. None of that
is fat and therefore no extra readings per day can
possibily have a rational reason related to a program
aimed at fat loss. Of course motivation to start dieting
in the first place is often an emotional decision not an
objective mecdical decision.

I brought the point a few years ago, and
someone said the water loss is in the breathing. The second thing is
that I sometimes weight one more pound after taking a shower. Did my
body really suck up a pound of water?

Does your scale really have an accuracy and repeatability
of less than a pound? No. Back in junior high school
science classes I remember learning about error bars and
estimating the size of data errors when doing experiments.
Is this no longer taught in schools? Given the confusion
two presidential elections ago when the vote in Florida came
out closer than the size of the error bars I guess not. All
instrumentation has some amount of error built into its
readings.
