How often do most of you hit those plateaus where your body just seems to say nope gonna hang onto this fat a while longer

In the past when I was very successful taking weight off (prior to a break up then bad hip that required surgery and almost 2 years inactivity) they seemed to be further apart....like 20 or so lbs.
Now it seems like 5 lbs come off fairly consistantly and then I get stuck for about a week or two ....then bam it starts to slowly come off again and 5 - 7 lbs get stuck again. I dont mind slow and steady because it is still coming off and my eating is getting better.
I recently got a Fitbit and I am staying well with in the cal in range and beating almost all the "goals" daily for steps, stairs and miles walked....I chose the sorta hard plan where I shoot for a deficite of 750 cal a day.
I know plateaus happen but I liked it way better when they were further apart and after larger losses!!
