IMO, no. Fasting isn’t this magic spell that sends fat away. Gotta be at a deficit.
If you can meal prep specific quantities that you know for certain are gonna be below your TDEE without counting, that could work. As in “chicken breast, portion of rice, portion of grilled sautéed veg, a handful of olives”. OMAD could also work since there is a limit to how many calories you can eat in one (reasonable) meal.
Keep a master list of the calorie totals for foods you usually eat in their usual quantity. You can eat mindfully and make informed choices without tracking every bite you eat, of course, but the more you know the better equipped you’ll be. Especially at first.
I’m new to IF, but have done keto for health reasons in the past and had one calorie counting diet where it took a while for my weight to come back. In my opinion it mostly comes down to how sustainable a diet (or any lifestyle change…) is. It’s great to loose the weight, but if you lost it through drastic measures, then the even harder work starts at the end of weight-loss: how to maintain that weight while not feeling deprived of some foods, or slip up. I’m doing IF at the moment with the goal to keep this most days going after I reach my goal. I have lost a bit, but eat well and have not strictly cut out anything, because this is how I want to keep eating.
But above all, be kind to yourself. Don’t be disgusted. Consider it just a little mistake maybe, if at all. We all make mistakes. If you haven’t yet, maybe look into mindfulness. It helped me immensely in several areas of my life.
