Apart from the rest of the stomach, eating at night is not the root cause of obesity. Whether you are fat or not is related to the total calories you consume all day, and has nothing to do with the meal time. However, it is still recommended not to eat supper for a long time, especially after midnight, because the stomach needs to rest after nightfall.
You can prepare some pancakes and milk. Milk helps to sleep. If you can't drink milk, you can switch to yogurt. Caking is less harmful to the stomach. My mother is hungry and painful at night. She always eats pancakes because she is too full to sleep.
Hope to adopt, thank you.
