Overview
When appetite falls sharply, the risk is not just eating less but eating an unbalanced diet: skipping protein, drinking too little, and living on small amounts of easy carbohydrate. Planning replaces willpower.
Why it's done and who it helps
Everyone in the first three months of treatment, and particularly people on dialysis who cannot afford a drop in nutritional intake.
A simple structure
- Three small plated meals rather than grazing, so you can see what you have eaten.
- Protein first, then vegetables, then a measured carbohydrate portion.
- Keep two or three "safe" reliable meals for the days after a dose increase.
- Plan the day before rather than deciding when appetite is at its lowest.
Eating out and social meals
Choose grilled protein with vegetables, ask for a starter-sized main, and expect to leave food. Alcohol is best limited: it adds calories, worsens reflux and can mask hypoglycaemia if you use insulin.
Preparing for your appointment
What if I cannot manage three meals?
Tell us. Persistent inability to eat is a reason to hold the dose, not to push through.
Should I count calories?
Usually not. Portion structure and protein adequacy matter more in kidney disease.
When to contact your care team
Contact the clinic promptly if you have any of the following:
- Vomiting or diarrhoea lasting more than 24 hours, or you cannot keep fluids down
- Passing much less urine than usual, or new swelling of the legs or face
- Severe pain in the upper abdomen that spreads through to your back
- A weight change of more than 2 kg in a week that is not explained by fluid
- A missed weekly weight, a missed dose, or any hospital admission
If you are seriously unwell, contact NHS 111 or your renal unit directly rather than waiting for your next review.
