Congrats!
I recommend just upping it about 5g per week to ease yourself into the change until you reach your comfort level. If you are wanting to stay in ketosis, that will also help you determine where your personal ketosis cut-off is with a lot of accuracy. There won't be any shock if you go slow. You'll know when you hit that cut-off. And then you can back off.

For me, I know when I've eaten too many as I WILL gain 3-7lb of water weight overnight. It depends on the kind of food I've done it with. If its LC-food, and I've just gone a little too far, then it's at the lower range. But if it's high starch or fruit or sugar/corn syrup, it does the high number. Sometimes I indulge, but I make sure to keep it not often. The water weight goes away 5-7 days later if I go back down to my normal ketotic carb level.

For me knowing it's just a temporary one-off, I don't freak over it.

I'm personally struggling with my weight right now. I hit my goal weight in Dec, but immediately it bounced back up and I've been waffling between 2 and 6lb over my goal weight since then. My carbs haven't changed. And I'm trying to build muscle. I just haven't found the calorie level yet that is perfect to keep it where I want. My body seems determined to be around 2 or 3lb up. Frustrating. But my clothes still fit fine, and I still look like I'm the same weight, so I'm just trying to give my silly metabolism the time to stop freaking out over yet another change and stabilize.

I tell you this...(See! I DO have a point to my rambling!) so that you aren't surprised if it takes a few months at maintenance to get everything "locked in." This is an endless marathon and your body is still going to be occasionally silly and so is the scale, as it ever has been. It takes a little time for your body, and you yourself, to figure out how to find the perfect conditions for cruise mode. It may take a little time to "settle in" to maintenance.

Anyway, keep up the fantastic work.

I agree with @baconslave's advice. I hit my original goal weight recently and decided to try to lose another 3-5 lbs (trying to get body fat to 24%) and also focus on strength training.

I did bump up my calories by 50/day so that adjusted my macros a little bit. I also plan to increase very slowly so I can figure out my sweet spot. I know if I get closer to 100 gm carbs I'll struggle far more with hunger and cravings. I'm guessing for maintenance I'll probably be somewhere in the 50-80 range but we'll see. I also haven't decided if I want to try to stay in ketosis long-term or more general LCHF. Not sure if this is helpful but just sharing my own thoughts and approach fwiw. Good luck! I've done so much yoyoing, I really want to be careful this time around!!
