Use less rich desserts. Make low calorie desserts, or use fruits instead. Don't eat between meals. Instead of eating more food at night, and little or no Breakfast, try eating a good breakfast, with only a small supper. This could lead you to go off your diet, and then even eat more than before.
Many people eat too much because they have something inside that feels empty.
They want love, or happiness, etc. And, don't be afraid to ask God for willpower to help you make the decisions you must make every day to help you lose weight.
