Plateaus are a normal part of the weight loss journey. You may find that mixing up your diet and/or exercise routine will get your scales moving again.
In the meantime, take a moment to notice whether your clothes are feeling looser, or maybe your knees ache less than before, or perhaps you are climbing that flight of stairs without getting puffed. These are NSVs (non-scale victories) and they are just as important as seeing the numbers move on the scales.
