Can you tell me how to control overeating?

Behavioral change: For long-term control, slowly reduce the size of meals with portion control. Replace high calorie foods with lower calorie foods. Do away with sugar soda/drinks and go with light drinks/sugar free/tea/water. Keep track of calorie intake with a logbook or application. Regular exercise allows better use of energy and tends to curb appetite. Don't eat when you aren't hungry; no junk food at home.

Seek help.: A history of depression or other mental illness could lead to overeating secondarily. With adequate treatment, your overeating could stop. Otherwise, adding fiber to your diet will curb your appetite and reduce the tendency to overeat.
