A good nutritional status improves your quality of life and your sense of wellbeing when you are fighting cancer. It is important that you try not to lose weight when you are having your treatment as this can cause you to experience worse side effects and you can become tired and weak. If you are losing weight unintentionally, this can often happen quite quickly and you are losing muscle as well as fat. This can reduce your strength and increase your level of tiredness if it is not managed as early as possible. People who are finding it difficult to eat enough, and are losing weight as a result, need to find ways to get more energy and protein in their diet. I can advise you on the best way to do this considering your likes and dislikes and any side effects you may be experiencing.
