Weight loss help (Fat loss as well)

hello everybody! I am looking to lose weight and fat from all areas of my body. I am not good at working out or keeping up a workout, but I need to know what would work for myself.

Female, 5'3, 200+ pounds more focused on back fat, stomach fat, arm fat, and face fat. Losing weight

As somebody who is not able to keep up a work workout due to mental things , I am wondering if a waist trainer and a sweat band would help me lose weight and fat. I do like doing cardio as it’s not too bad on my body so how much cardio would I have to do a day in order to see progress by? Let’s say the end of the month or a week. I do have bad eating habits as well, but sadly if I went on a diet, I would either under eat or over eat due to my eating disorder. If you have any tips for that, I would also take them. Thank you!
