Hello there...., following these steps would help- Eat more frequently.... Schedule five or six small meals a day....Set times of the day when you are normally hungry. Eat at those times even if you do not feel particularly hungry....Eat healthy high-calorie foods.Eat protein-rich foods.....Drink nutritious fluids (such as milk or juice) between meals instead of during meals. ....Drinking too much during a meal can make you feel full too quickly....
