I know this is obvious, but I thought I would mention it anyway.
If you are putting on muscle mass from your exercise, that is good weight. (IMHO) SO, it's possible to lose fat, but gain or maintain weight because muscle weighs more. This why I don't use a scale -it tells me nothing useful. I think people in our society spend way too much time looking at numbers on a scale,and not enough time actually observing their own bodies.
Taking body measurements is more informative, as I can see if I am getting larger or smaller in a good way. But so is just looking and feeling how my clothes fit
.
If you are able to get your body fat accurately measured it's worth checking that now and then, I suppose. (I'm skeptical about this, but that's just my way).
For reference, here is article about various body fat measurement methods, which all have limitations:

Since eating this way I am a bit larger in the shoulders,lats, biceps, etc. due to improved muscularity. I love it! This probably would mean a few pounds more on the scale, if I had one, but I don't care. Muscle weight is good.
P.S. I am also turning into an oats addict, but I love that too
