Edit: I really want to loose weight and the fact that she is buying all this is not helping because I can’t not eat it without her noticing.
how do I get my mom to stop buying me junk food without becoming suspicious? If I tel her she will think I have an eating disorder and take me to a doc (it’s happened before) I can’t hide it not eat it or buy my own food because she notices.
Are you saying your mom took you to a dr because you weren’t eating junk food?
If that’s true why didn’t you tell the Dr in front of her that you were trying to eat healthy stuff. That was the time to talk about junk food with your mom and Dr.
I think your mom needs to take a cooking class. Or you need to learn how to cook yourself. Or do you have no kitchen at all? If you're in such a terrible position that you don't have a kitchen (which I doubt), then you can look at the options by the link here. But you'd better just talk to your mom directly. I'm sure she won't be offended.
What's the problem with junk food? I'm pretty relaxed about it and don't think there's any problem with it. Anyway, when I went on a food tour lisbon, I tried a lot of different foods including fast food and street food. It was delicious and worth the trip to lisbon. It's a trip that burns calories anyway.
