What is a balanced diet?

To have a balanced diet you need to eat a variety of foods that provide the correct amount of nutrients your body needs to grow and work well, such as:

  • Protein to help your body to repair itself after illness or treatment and fight infection
  • Carbohydrates for energy
  • Fats
  • Vitamins and minerals help your body to use the foods you eat. They are used by your body to give you energy, repair and build essential tissues, and help with lots of body functions.

The food pyramid

You may need to eat different types of foods or different quantities. You might need special advice from a dietitian to keep a good balance in your diet. Ask to be referred to the dietitian if you have any worries about your diet .

Getting active

Taking some exercise is one of the best things you can do to feel as well as possible. It can:

  • Improve fatigue and other side-effects
  • Increase your energy levels
  • Help anxiety and depression
  • Improve your mood and quality of life
  • Help you to keep a healthy weight
  • Strengthen your muscles, joints and bones

Talk to your doctor about becoming more physically active. They can tell you what is safe and suitable for you and may be able to recommend a special exercise programme for people who have had cancer treatment.

Body mass index (BMI)

BMI is a number that tells you if your weight is right for your height. BMI is graded so it can tell if you are underweight, a healthy weight, overweight or obese (fat).

Underweight   Healthy Weight   Overweight   Obese
18.5 or less 18.5-24.9 25.0-29.9 30 or more  

Your dietitian can measure your BMI. Sometimes there are scales in shopping centres or pharmacies that will measure it for you.

BMI is a guide only. Most people are advised to keep their current body weight during cancer treatment. If you are worried about your BMI score, talk to your dietitian. If you are losing or gaining weight, discuss it with your nurse, doctor or dietitian.

Measuring BMI yourself

You can also calculate your BMI yourself. But first you will need to know your weight in kilograms (kg) and your height in metres (m). Divide your weight by your height and then divide the result again by your height. There are also websites that can help you to calculate it.
