What are your thoughts on dirty fasting?

Hey guys. I’ve always been into fitness and am fairly healthy. Nonetheless around Christmas 2022 I decided to track calories and macros to see what my habits where (something I did in university) I realized IF a few times a week + 36 hour fast every 10 days or so made it waaayy easier to keep in my macro averages.

Am m34 6’1” and went from 220lbs then to 190lbs now! Great results. Close to being the leanest I’ve been in a decade!

Anyways here’s my question: for 36 and 72 hour fasts is mild cheating/dirty fasting OK?

Sometimes I’ll have a few nuts for good fats, cream in my coffee, a piece of celery or like a single bite of the dinner my wife made. I feel if it’s 500 cals or less I’m still getting benefits from the fast. Thoughts?
