Divide a regular three- meal schedule into six to eight smaller ones. Eat snacks between meals. Establish a pattern of eating meals and snacks at definite times. Stick to the schedule even when you are not hungry. Keep snacks handy for nibbling.
People tend to eat more when food is readily available.
Rely on foods you really like at times when your appetite is not good. Substitute high calorie, high protein drinks when foods are unappealing. Prepare foods that have a pleasant smell. These can help stimulate your appetite. Remember that maintaining your nutritional intake is not just a good thing to do for yourself, it is very important for your health and recovery.
