Reached my Goal weight :)

Congratulations! As for maintaining, I'd just say keep on doing what you're doing, just don't force as much of a deficit.

Have you figured out what your sweet spot is in terms of calories per day? If not, then I'd increase a bit and watch for a week or two... The weight will fluctuate over time, so identify what range you're happy with... If you go over the top limit, eat a bit less. If you go under the lower limit.. Eat a bit more.

Now it's all about fine tuning the machine.
