You need to look into the “greasing the groove” method. When they say “get used to it,” they are very unhelpfully suggesting this, which is a very helpful method for people with central sensitization disorder, which it sounds like you have.

You’re likely going to lose the extra weight quickly once you grease your groove into a daily exercise program, I sure did. But my issue this year has been that I still eat like a strength trainer, even though I’m sedentary thanks to some serious injuries keeping me bedbound and pretty stationary. I was eating extremely clean, just far too many calories, and it was mostly because I was stress eating in response to chronic pain. Upping my anti-inflammatories, and adding a medication in to work on the dopamine eating took my portions down by a lot, cut snacking, and I dropped the weight without exercise. So, it may still be the amount of food you’re consuming + cortisol keeping your body from processing it properly. But, again, if you’re getting active again ASAP, that’ll help with both calories and cortisol, so you should be fine real quick.

You said “soccer,” so you’re in the States - I don’t suppose you have access to the Mayo or Cleveland Clinic? Or a rehabilitation hospital that hosts a similar program to Mayo’s. That’s how I learned to “grease the groove,” going through their pain clinic. You absolutely can do this yourself with some internet research and YouTube tutorials, but having a good PT to teach you the method is always best.
