Because my weight fluctuates so much during the day (up to 10 lbs), I decided a few years back to learn as much as I could about the fluctuations. I started weighing about 10 to 20 times a day and logging some of the results (and just noticing others).
Getting dressed obviously adds pounds that aren't really mine, but specifically I learned that:
my underwear weighs less than a pound
pajamas about a pound
jeans and a top - 3 lbs
with shoes about another pound to pound and a half
a dress or slacks and a top - about 2 lbs
the water on my skin after showering - about 2 lbs (a little more if I don't dry my hair well)
16 ounces of water - a pound of course (until I pee it out in about 30 minutes)
meals - up to 3 lbs
going to the potty - 1 to 3 lbs
the difference between last night weigh in and first morning weigh in (after using the restroom -about 2 lbs)
eating a high sodium meal such as asian food adds up to three pounds for a day or two
eating higher carb than my normal, adds about three pounds for a day or two until my eating returns to my normal
PMS adds up to 8 lbs gradually over two or three days and then lost in about five days
this summer a sunburn added two pounds (and I relearned that the body retains water when healing from illness or injury because the healing process uses that water to heal)
My experiment taught me that fluctuations are normal and for the most part not very mysterious. I can't gain a pound from eating one candybar over and above my foodplan. It's impossible to gain more from a food than the food weighs - so a two ounce candybar at most can account for no more than a two ounce gain (which is why whenever I weigh myself I see it as "worst case scenario." I know that if I'm not eating very cleanly, have a high carb or sodium day, or if it's near TOM then what appears on the scale is higher than what I'll weigh in just a few days)
If you weigh frequently and at various times of the day, you have to learn to only compare like to like and only compare weigh-ins at least a week apart. You can't compare naked morning weigh-in with post-meal-post-shower weigh-in. You can't even really compare naked morning weigh-in to yesterday's naked morning weigh-in.
For a while I was only "counting"/comparing my "Monday morning weigh-ins" but even that was screwing with my head because of my monthly cycle, so now I only compare weights that are 28 days apart (for example today's morning weigh-in with weigh-ins four weeks ago and four weeks in the future).
