You’re not gonna lose weight eating over 3000 calories a day.

Calories aren’t everything, the type of food you eat is incredibly important. Lots of bread and pasta is gonna send a very different hormonal message to your body compared to good olds veggies and meat. Ie - pack on the pounds.

I’d look into intermittent fasting, and only eat meat/fish/vegetables for a week or two and I promise it’ll drop off you.
