Diet and physical activity after acute lymphoblastic leukaemia (ALL)

You might start to think about your diet and physical activity after ALL treatment.

Exactly what you can do varies. It depends on the treatment you have had and how fit you are.

Diet and ALL

Diet plays an important part in coping with cancer and its treatment. A good, well balanced diet can help you feel stronger, have more energy, and recover more quickly. When you are having treatment for ALL, eating can sometimes be a challenge and knowing what to eat can be difficult.

After treatment, most people can eat whatever they want.

While having treatment your weight may have changed, and you might have lost weight. This may be because of your treatment side effects such as:

  • loss of appetite

  • taste changes

  • feling sick

  • a sore mouth

  • constipation or diarrhoea

Or you might have put on weight from the steroids you had as part of your treatment. 

If you still find it difficult to eat, you can try high calorie and high protein drinks. You might have had these drinks during treatment. Once your treatment has finished, you should begin to feel better and be able to eat a normal diet. This can take a while after intensive treatment.

What foods should I eat?

After having cancer, many people look at their diet and make changes, deciding to choose healthier options.

For a healthy diet, eat mostly:

  • vegetables

  • fruit

  • wholegrains like whole meal bread, brown rice and rolled oats

  • healthy sources of protein like fish, chicken and pulses (such as beans, lentils and chickpeas)

Have less:

  • processed and red meat

  • sugary drinks

  • high calorie foods like fast food and food high in sugar

  • alcohol

What should a meal include?

It is important to eat a varied diet. This includes a range of food in the right proportions and drinking plenty of fluids. But this doesn’t mean you can’t allow yourself the occasional treat.

The diagram below shows you how much of each food group you should eat each day to follow a varied diet.

Physical activity and ALL
