The scale is one of the least accurate ways of tracking fat loss. I mean, it will show gross weight, but that fails to take into account any body composition changes ie water, glycogen, visceral fat, lean tissue...the scale obviously cannot discriminate between these.
It has its place, but Id reccomend you start measuring the following weekly as well:
*Stomach circumference, just below belly button and around love handles
*Chest: nipple-line and under armpits circumference
*Bis flexed circumference
*Upper thigh circumference, try for a consistent spot
Currently, you seem to be on a good trend, and your kcals are already lowish, Id stick with things til you start to plataeu.
