I am a total fan of getting enough lean protein

where I differ from others is that I dont ascribe to having to hit a magical number at the high end to continue losing weight.
I
definitely agree that you need to plan, plan, plan what you will eat and while you are starting out weighing and measuring the food is great to get an idea of what a "portion" looks like.
As Robin said you may already be consuming some extra calories unless you are measuring everything out and logging it.
My concern is seeing people get so frustrated by "am I eating at the right level to continue to lose weight" when they are losing quite nicely and have already made some amazing changes from the way that they used to eat. (to me, if I weigh less at the end of one month than I did in the previous one then that is a success . . . I have done the superstar weight loss and halved my bodyweight in 9 months but I dont need to be a superstar anymore . . . I like this place of calm much better

and that is the way that I will get to my real goal - of peace around the body/food/mind issues)
Ultimately if you are getting a good selection of fresh foods, enough 'good' carbs (if your body can cope with them) and lean protein and are taking in some sort of exercise (walking is a great start!), get to the end of the day and feel like a rockstar and not deprived by what you are eating AND the scale is co-operating, why change it?

I'd like to see more celebrating of fabulousness by all of us who have made huge changes.
