​​​ What Is Cancer-Related Fatigue?

Cancer-related fatigue (CRF) is when you feel physically, emotionally or mentally very tired because of your cancer or cancer treatment. It is the most common side effect felt by people with cancer and can be the most stressful. CRF is a different feeling than the fatigue (feeling of being tired) of a person without cancer. CRF can be more severe than feeling tired, and it is not relieved by rest. How severe the fatigue is and how long it lasts is different for everyone.

​​​ Nutrition Is Important When You Are Fatigued

Poor nutrition can make you feel tired and weak so it’s important to eat well when you have fatigue. Here are some ways that you can stay fueled when you’re too tired to go grocery shopping, prepare your meals or eat.

1. Build Your Nutrition Routine

  • Stay hydrated. Drink 6 to 10 cups (1.5 to 2.5 litres) of liquids each day unless your doctor tells you otherwise. Juice, milk, soups, water and decaffeinated tea all count as liquids.
  • Keep track of when your energy is best. Schedule your eating during these times.
  • Eat 5 or 6 small meals during the day instead of 3 large ones.
  • Post a schedule or list of snack ideas on your fridge for easy reference.

2. Make Every Bite Count

  • Eat high calorie, high protein foods
  • Limit caffeinated drinks (like coffee) because these drinks may disrupt your sleep patterns
  • Prepare soft, moist foods. You’ll eat more if foods require less effort to cut and chew.

3. Make Life Easy

  • Accept help from family and friends. Let them go grocery shopping or prepare meals for you.
  • Shop on-line for your groceries and have them delivered.
  • Have community-based companies prepare and deliver fresh or frozen meals for you. You can find a list of some of these services at the Princess Margaret Patient & Family Library.
  • Use disposable plates and cutlery for easy clean-up.
  • Organize your kitchen to decrease your workload. For example, sit in a chair to peel potatoes.
  • Stock your kitchen with easy to prepare foods. The list below can help you get started.

If your cancer-related fatigue is making it hard to eat, ask a member of your health care team for a referral to a registered dietitian at the Princess Margaret. The dietitian can help you create a healthy eating plan that’s right for you.
