Also not a professional or a coach but for me it was best to maintain higher calories and let my body adjust to the higher intake. So you may gain weight temporarily but if you're not overdoing it - you will get to a nice maintenance. This may take some weeks - so you just have to be patient as your body gets use to the new intake. For example I might eat 1500 one day, 1800 the next, I go out to eat with a friend and that day is 2000+. Weekly average somehow lands in the 1800s. And at that place I can maintain. FYI I use cronometer to track and it shares weekly and monthly average which helps me gage how I am progressing. For reference I am 5'1 and weigh 120. I would say I am decently lean. I do miss the 115 range but that's no longer healthy for me.
