Exhausted by my families constant nagging about me "not eating enough."

This is kinda a rant. I've been on (or at least trying to follow) a calorie deficit for around four months now. But the thing is, I'm middle eastern. If you're middle eastern, you probably already know that a lot of middle eastern families are a bit too generous when it comes to food portions. I have lost weight, and it is pretty obvious to ppl around me, but I'm still overweight, mainly due to the fact my mom gives me food twice the normal serving size. Like for example, when she makes spaghetti (she rarely does but it is just an example lol) she puts like double-triple the normal serving and I cannot just eat till I feel full or else my mom would start lecturing me, saying stuff like "You're starving yourself like this!! You barely ate anything on the plate, you're going to be low on energy the entire day and you won't be able to focus on school tomorrow!!" and then she forces me to eat almost the ENTIRE plate (which I do not even wanna count how much kcal is in it bc I know I'll get a heart attack lol). When I'm at a restaurant with her, and I want to get something on the menu that isn't too high in calories, again she starts lecturing me "This isn't enough for a lunch!! Why dont you get something else along with it and eat this as a side!!" And when i tell her I'm genuinely fine and I WILL get full from what I'm going to order she secretly orders something else for me to eat on the side. This also goes for seet treats "You didn't eat chocolate at all today! Chocolate is glucose, you need energy for your studies, you're trying to starve yourself or what??" There have been a million of convos between me and my mom like this for the past 4-5 months, and it EXHAUSTS me. I do not think she understands that just because I'm not eating like a family of four, I'm not starving myself. I love my mom to death, but this has been a problem for a few months now. I have been overweight since covid started, slowly gaining weight throughout the years, until I realized I do not want to stay insecure for the rest of my life for something that I can easily fix. But I'm getting exhausted
