01Short answer

Portion size, fewer sugary drinks, walking if allowed. Weight loss with dietitian and team. No detox.

02Simple explanation

No harsh starvation.

Watch portions.

Fewer sugary drinks.

With a dietitian.

03Scientific explanation

WCRF/AICR: healthy weight links to long-term risk.

ESPEN: protect muscle — need protein.

Fasting does not replace treatment.

04What happens in the body?

Why it matters

Extra fat can raise other health risks.

Nutrition direction

Vegetables, protein, grains; less fast food.

With leukemia treatment

Sometimes weight loss is planned after a treatment phase.

Questions for your team

Can I lose weight now? Calories? What on steroids?

When two diets clash

One condition's diet can conflict with another's: for example, leukemia needs energy and protein while another illness may call for limits. In such cases the haematologist, the specialist and a dietitian should decide together — don't add restrictions on your own.

Medicines and food

Some foods interact with medicines (for example, grapefruit changes blood levels of several drugs). Steroids can raise blood sugar. Talk to a pharmacist before starting a new food or supplement.
