Mondays weight in
Since I stopped salt (sodium to its lowest), I do not have anymore issues of weight going up one day and down the other day.
I don't know if this could be the issue with you, but it was for me!
I now added a bit more sodium, cause I was having muscle cramps, but I didn't add a lot, and now I am fine.
Maybe you had too much salty things this week?

Seriously don't panic. This last week I weighed every day and you should have seen the scale jump. I went from 376 to 369 to 378 and then 375 and then finally back around to 370 on Monday. Who knows what was causing that gain and loss session this week.
