If you are exercising regularly, I wouldn’t expect a huge change if you skipped one day. But for periods of no exercise of a week or so, this doesn’t seem too unexpected.

Not only does [exercise increase your carb requirements and insulin sensitivity](https://forum.fudiabetes.org/t/how-exercise-increases-the-effect-of-insulin-and-carb-usage/3857), but it also [increases the the level of GLUT4 expression](https://www.ncbi.nlm.nih.gov/pubmed/8182045). After a week of no exercise, this can change dramatically.
