The problem with going to low on calories OP, is that you just won’t stick to it long term.
The reason very low calorie diets don’t work (in the sense that you will not keep the weight off) either is that IF you reach your goal, you will just return to old eating habits after and therefore old calorie intakes.
You need to find out at which calorie intake you will lose, but can also stick to long term. As PPs say, find out your TDEE and then reduce by 10-20%. It will be a lot more than 1,000 per day.
Then you need to try and find ways to fill that number of calories with as much VOLUME of food as possible. So choosing lean protein sources and veggies over most other things. Something like a stir fry with a chicken breast diced up and thrown in is a good example. You can add some noodles too, but instead of using a sweet pre-prepared sauce, use a teaspoon of miso paste, some minced garlic and soy sauce for flavour. Things such as this will fill your plate but be low on calories.
Another example is my dinner from a couple of days ago, pic attached. 2 egg, 45g cheese omelette, ham, homemade coleslaw with light Mayo and mustard, rocket lettuce dressed in balsamic. Just under 500kcals but a huge plate full.
If you do it this way, you will naturally work out your maintenance calories along the way. You might need to re-do your TDEE as you lose weight as it will change, but you will have learnt to eat in a way that is satisfying and maintainable along the way, so you don’t return to old habits once you are done.
It has to be a lifestyle change, not a diet.
Good luck OP.
