It will probably rebound by about 5 kg, because you didn't train your stomach very much when you were dieting before, and you can't digest much if you eat more, but you will definitely rebound a little, so don't worry too much! If you continue to reduce, you should not reduce too much!

I did the same thing in college. I was basically the same as you when I was a freshman, but I couldn't reduce it to a certain extent. I still lost the same weight as I did then!
