Stalls are stalls. There is absolutely no rhyme nor reason to them, they just happen. People try to break them by upping or lowering calories, changing exercise regime, whatever. And when the loss restarts they SWEAR that what they did caused the renewed loss.
The fact is, stalls last a few days, or worse, a few weeks and then they end. If you stick to your programme you'll start losing again soon. You don't need to do anything drastic.
