why can a person’s weight change +/- 5-10 pounds a day when they definitely aren’t eating 5-10 pounds of food/water a day. Where does this extra mass/wight come from?

It cannot. Conservation of mass applies – if you weigh 100kg in the morning and don’t ingest anything, you cannot weigh >100kg at the end of the day. You might have a measuring instrument variation, since home scales are not precise, but as you clearly point out, no extra mass can come from nowhere.
