Your body has probably adjusted quickly to the schedule / you hit an early plateau, so shake things up - you have tons of ways to do that easily: make a couple of your eating days OMAD / do a couple of rolling 48 hour fasts, go very clean keto for a couple of meals/days, do some exercise.

I was on a long term plateau myself not long ago and it took me a couple of weeks to break through it. I did OMAD with random 48 hr fasts sprinkled and pretty clean keto. As 9tacos said in the other comment, trust the process - eventually your weight will budge.
