How can I possibly weigh 2 lbs. heavier overnight???

Sounds like water retention. Could be sodium or something else. Wouldn't worry too much. Anything that comes on that quick, comes off that quick. What's your 200 moving average ;o)

Probably water weight, or maybe you are about to drop a bowl wrapping dump.

Water, or inconsistencies with your scale. Since 60% of body mass is water, a change of 1 % can be a 1.5 - 2 pounds body weight. Weigh yourself every week, not every day, you'll get better and more accurate results.

2 lbs. is easily gained or lost over a day for a variety of reasons that have been touched on already (dehydration, dropping a duece, sodium, etc). When I am losing weight I can vary during the day by 5-6 lbs (more variance then when my weight is steady for some reason). Don't weigh yourself daily, weigh at the same time, weigh on the same scale. Just keep track of general direction, there will be some fluctuation.

Have you conducted a meaurement system analysis with your scale?

Did you do inventory on your pillows?

I don't see the downside of weighing myself daily.

I typically do it 3 times per day: I weigh myself after getting up, again after a run (before showering) and then often at night (after dinner).

Obviously after dinner I weigh the most and after my run I weigh the least. My morning weigh in is somewhere between the two.

Hot day, long run, I will be ~153. After dinner, I will be ~158. After waking up, ~155.

^^^ This is wrong. If you want more accurate results, buy a more accurate scale and keep it calibrated.

No, you are wrong. Actually, you are probably just misunderstanding his post.

His point is that body weight fluctuates. For instance, no one weights 153 all the time. If you weigh 153 and drink a quart of water, you are going to weight more. If you take a huge dump, you will weight less.

His point was to be a little less manic about the whole thing, no one weighs the same thing every day.

Okay, I do realize that weigh is not spelled weight. I have no idea why I did that twice. Sorry.

So you agree then that you would get a more accurate value by taking more frequent measurements, not less frequent.

Take the 155 +/- 3 guy. If he weighs himself 1 week apart he could get 158 today and then 152 next week and think, sweet, I'm doing great losing weight. Then a week later back at 158 - Shit, I shouldn't have eaten that burrito, I need to be annorexic if I'm ever going to get down to my racing weight :( Since I went from daily to weekly these readings are more accurate, so I definitely lost 6 pounds and then gained it all right back.

VS.

Hey, I'm 155 when I wake up. I'm 152 after I go run in the heat. I'm 158 after I eat a big burrito. My average today is 155. If in a week everything has shifted 1 pound, I may have lost a pound.

I totally agree with you.

There's no real point in the multiple weighings though. Just weight yourself at the same time every day (probably right before you go to bed or right after you wake up) and watch the trend. There's no real reason not to weight yourself 3 times per day, except that it is slightly obsessive, but there really is no benefit to doing so.

Perhaps the position of the moon pulling your fat butt cheeks down.

I found I can easily lose weight by just lifting up one of my legs when I'm weighing myself. Took a genius like me to figure that one out. Dummies.

You ate a salty meal...

or you need a dump.

or you drank lots of water.

or you didn't run yesterday, so you're are not as dehydrated

or you're wearing different clothes

Weight fluctuates daily, perhaps by 2 or 3 pounds.

Yes, totally agree (and I'm the one that does it). I admit it is a bit obsessive and has no benefit, but it demonstrates the variability.

Was it literally "overnight"? Are you using Ambien to get to sleep?

Maybe you are sleep-eating.

Nobody takes a 2 pound dump.

Your gerbils aren't missing are they?
