Why would that be? To lose why your are taking a net negative mass balance, once the weight is lost you probably can't go back to the exact diet you had (otherwise you wouldn't need to lose weight) but an mass neutral one should suffice to keep you at the same weight.

I've tried mass neutral diet and it didn't work. Somehow my body was able to sustain 105kg on about 1000kcal daily for two weeks. After that, my mind broke and I thought about food like a narcotic, just couldn't continue that diet.

If you are a 300 pound person and want to be a 150 pound person, you have to eat like a 150 pound person. Forever.

You are both correct, not sure why OP is downvoted though.

If your caloric requirements are 2400 calories a day. You might eat at a deficit for your diet, say 1700. And after that you can eat 2400 again.

As body mass increases, the caloric intake required to maintain said mass increases. Likewise, as body mass decreases the caloric intake required to maintain said mass decreases. Fat people need to eat like the not-fat version of themselves in order to both lose weight and maintain their new mass. If "balance" is 2400 calories for their fat body, resuming eating 2400 calories will lead to them becoming fat again.
