<human>: I am 17 and here are my stats:

Height: 5'9

SW: 218lbs

CW: 170lbs

GW: 140lbs

In the past 7ish months I have lost almost 50lbs and I am pretty proud of myself but I have been stuck at my current weight for over a month now and I am starting to get sick of it. I have been getting by by doing a lot of estimation on MFP which worked well for me until now, but I know that using a food scale would help me get over this plateau and help me get to my goal weight sooner.

However, being 17 means that I live at home with my Dad and brother. This means that I can't really do anything or change in the long term without either of them knowing. My Dad also likes to keep track of how I am spending my money, which means that I can't go out and buy a food scale without my Dad finding out. I told him that I was planning to go out and get one, and that I wanted to start measuring my food so I can accurately log it and speed up my weight loss. Despite me doing it for over half a year now, my Dad still cannot accept the fact that I am logging my food. He sees it as an unhealthy obsession to use an app to write down every little thing I do. He doesn't understand why I can't just eat freely like he does and be naturally thin and toned like he is... (I guess it never occurred to him that I inherited my normal/slow metabolism from my mother).

Therefore he refuses to let me buy a scale and promises that if I do, he will have to contact my school or get me counselling because this means I automatically have an eating disorder and am anorexic (which I clearly am not, as you can see from my stats) or bulimic or something. So here I am, Reddit, to ask you how do I go about teaching him, a pretty stubborn person, that it is not a big deal and I am not mentally ill for wanting to keep track of things in my life and not just breezing through life with no care in the world like he did.

Can you provide a brief overview of the text?
<bot>: My dad is ignorant and stubborn. Won't let me buy a scale. Thinks I'm gonna die. What do I say to him?
