Weaning myself off from my current diet

For the past ~5 months, I have been on a diet of 1400 kCal + half of kCal expended in exercises . This worked very well and I’ve lost almost 20kg. I’ve blasted past my conservative weight goal mind-way, past my realistic weight goal a few weeks ago and at my current weight loss rate, I’m going to reach my optimistic weight goal in ~3 weeks.

So far, so good.

Now, I’ll need to start stabilizing my weight before I go overboard. This certainly means increasing my kCal budget, but I’m uncertain as to the best way to handle this.

* Should I increase the baseline to e.g. 1500 kCal this week, 1600 kCal next week, etc. until the needle stops moving?
* Should I rather switch from 50% of kCal expended to 75% next week, 100% the week after that, etc. until the needle stops moving?
* Any other option I haven’t considered?
