I think that you will learn how to maintain while you are on your journey
Also, I believe the first 6 or more weeks are the hardest when it comes to weight loss. All of us lose weight differently and you may see different results than what your mother has had. In my first month, I lost nothing and then lost lots the next month where I steadied out.
Good luck with your journey! You sound motivated and you have come to the right place for support
