Sorry this thread is so late. I do think it is important that people on mainenance have a space here. Our challenges are different. Losing can be done but keeping it off? That is where the real work begins.
I hope the Maintenance Crew is all doing well.
I have noticed I stay mostly about 4 lbs. under my original goal weight these days, only occasionally after I have slacked off and had more of somethings I rarely eat or drink,(I’m talking about you champers and brie), do I bounce up to my original weight, a 36 hr. fast always gets it back down in the 3 lb. range and then just eating normally, which is IFing most days for me, it will drift down further, sometimes as much as 6 lbs. Its a scale thing I am starting to believe, my clothes don’t fit any worse on the bounce ups now. In fact, some of the smaller clothes I bought right after hitting goal weight are loose now.
. Luckily, this weight was my actual original goal, but still. I KNOW it can’t be fat because I would have had to change my eating habits to gain fat back, and that hasn’t happened. Plus my measurements haven’t increased. I had an infection (wasn’t sick though - haven’t been sick in almost 3 years!), and then 10 days of antibiotics, so perhaps it’s water weight… but the antibiotics were done 4 days ago, so I’m just anxiously waiting to see how long it will take to get back to normal because the scale number just messes with my head so bad!! Why do I weigh myself? 
I have a screenshot from my weight that shows how volitol weight can be (it’s kinda of like cholesterol, right?). I’ll see if I can add it here. But it’s my weight in the morning and in the afternoon. Just a good reminder that weight gain is not always fat. It’s often water or food in our guts. I feel a bit bony.
