Sometimes cancer or cancer treatment can affect your appetite.

Though you might not feel like eating, it's important to do what you can to maintain your calorie, protein and fluid intake during cancer treatment. Use this information to help plan meals and snacks that will be more appealing and provide the nutrition you need to get better.

Keep in mind that in some cases, such as advanced cancer, eating may not affect the outcome of your illness or treatment. In these situations, trying to follow specific dietary guidelines, such as adhering to a low-sodium or low-fat diet, may not be practical.

Sometimes caregivers or family members can unintentionally add stress by pushing or trying to force you to eat certain foods. Ask your doctor how carefully you need to follow specific dietary guidelines.
