Honestly, the best thing I found was tracking my normal eating for 2 weeks. You find out what you would normally eat calorie wise during that time and you can change it from that. If you go from eating day 4000 calories a day to 2000 your body is going to absolutely hate you and while it might be a deficit you aren’t gonna be happy and will quit way easier. Once you figure out your base line you can reduce it by a normal number and gradually get down to a good real deficit. It’s kinda like how
You don’t go to the gym and expect to lift 70 lbs weights no problem when you are used to 30lbs. You have to allow your body time for gradual change. As much as it might suck because “progress” isn’t visible or being made fast, it is the healthier option and will allow you to feel better as you go though this journey. Also, when you lose it gradually there is less issues with excess skin and all of it “coming back” right away if you do mess up a bit.
Another tip, there are going to be weeks, even months, where nothing will change. Measurements, weight, strength will not change. And that is okay. Sometimes our bodies need to be steady and then they start going again. So if you get stuck in that stage don’t just quit, push though it
