The building-up diet

Macmillan Cancer Support Medical Reference

Food plays a big part in the quality of our lives. Mealtimes are often an important and enjoyable part of family and social life. Many people with cancer have eating problems and this information gives advice on how to manage some of them.

Many people with cancer find there are times when they can't eat as much as usual, and sometimes they lose weight. There are lots of reasons for this.

Cancer itself, or its treatments, may make you lose your appetite. Some people find that they do not feel hungry, or feel full soon after starting a meal. Other people find that food makes them feel sick or that their treatment makes some foods taste different.

Some types of cancer make your body use up more energy, even if you are not very active. This can make you lose weight even though you may still be eating well.

People who are not eating enough, especially if they are losing weight, need more energy and protein in their diet. If you have often tried to lose weight previously, it can be difficult to change your eating habits when you have cancer. However, if you have cancer and are losing weight you may need to eat differently to try to maintain your weight. Your doctor or dietitian may recommend foods that you would normally think of as unhealthy, but they have good reasons for doing this.

It is possible to get more energy and protein without necessarily having to eat more. Not everyone will be able to put on weight by making changes to their diet, but you may be able to slow down, or stop, further weight loss.

A good diet is one that gives you everything you need to keep your body working well. Variety and balance are key to a good diet.
