You don't lose weight by eating, you lose weight by not eating.

Go for a fast, either a complete fast for many days or do OMAD (one meal a day). Fasting is known as a healing technique for millennia so don't believe that it is unhealthy.

Avoid sugar and processed carbs because you'll get hungry again faster. Eat animal fat/meat and plant fat to feel satiated for a long time.

I am not fat but I am doing OMAD from time to time just to feel better. This will also cure every form of pre-diabeetis that most fatties have.
