I found that OMAD (one meal a day) works well for me. I've been consistently losing 1-2kg per month on it, and it's something I feel I could sustain forever.
OMAD can be tweaked for stable weight - e.g. by increasing the eating window from 1 hour to 2 hours, by eating more, or by adding an extra meal once in a while.
Weight loss slowed down naturally once I've reached a healthy weight range.
