First off, you don't just get an eating disorder because you decide to. That's something that just develops over time. Along with that, losing weight through disordered eating habits is both dangerous and unsustainable.
Secondly, losing weight only works if you are doing it for the right reasons and have the right mentality going into it. Considering the fact that you want to develop an eating disorder already says that this does not apply in your case. If you don't have a healthy mentality going into weight loss then you are going to be less likely to succeed. Either you'll probably end up giving up after realizing that weight loss takes a bit of time and that how much weight you lose or gain will fluctuate, or you will hit your goal weight and then gain all the weight back again not too long afterwards.
Healthy weight loss usually tends to involve eating in a calorie deficit (not an extreme calorie deficit), eating more satiating foods, increasing protein intake, and making sure to stay hydrated. That's at least what I have heard from people who have been able to lose weight healthily. It would probably be best to see if you can get in touch with a dietitian to see if they might be able to provide some help as well.
