You aren't cursed with a slow metabolism, you have just been having too many calories. If you are truly never hungry but still not losing weight, then why not reduce your calories by 200-300 a day?
I can find the calories to cut, it just makes it difficult to sustain for longer than 2 weeks due to the mental load. Plus, I would bet my lifts in the gym would suffer after a while too.
Frankly, it’s probably easier to just go for an extra 20 minutes run.
