The body can naturally fluctuate by several pounds from day to day, due mainly to changes in your hydration levels.
But 12 lbs in a day certainly is more than just hydration level changes.
My guess is that changes of that amount are due to an uneven floor, and the scale being tilted a slightly different way each time. Position the scale so it is firm and there is no 'wobble' (some scales have adjustable feet), and perhaps mark the floor with a little bit of tape to ensure the scale in is EXACTLY the same spot each time.
But even if you can eliminate this uneven floor issue, daily weigh-in are really going to tell you more about hydration level changes, than about dat loss.
Measuring yourself with the tape is actually a better way to track your progress than the scale.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

I have found that with digital scales there is a tendency for inaccuracy at times. The manual scales are probably more accurate but I find that they are difficult to read.

This morning, my scale weighed me at 185. That is quite a lot higher than it was a couple days ago, so I stepped up again this evening out of curiosity. Now the scale reads 173, which is much closer to the prior day's. The scale is only a couple months old, and I make sure it is balanced at 0 each time (no batteries to replace or anything). Has anyone else had this happen, or can anyone explain what's going on? It's entirely implausible that I would lose 12 pounds in one day, of course.
