I recently moved and have done nothing but eat. i've put on 20 pounds in 4 months. i've replaced meals with im limited on exercise what else can i do?

Can do full check-up: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and iceberg lettuce (little/no salad dressing). When shopping for fruits, buy small ones no bigger than a tennis ball, because fruits have sugar. Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar & simple starch calories!
