≈+200 kcal ≈+5g protein
💪 Protein boosters
Add 2–3 tablespoons of skimmed milk powder to porridge, soups, or sauces — virtually tasteless but adds protein
≈+60 kcal ≈+6g protein
Include full-fat Greek yoghurt as a side or in sauces to boost protein and calories together
≈+130 kcal ≈+10g protein
Add a soft-boiled or scrambled egg to breakfast or as a snack — easily digestible and protein-rich
≈+78 kcal ≈+6g protein
Include lean meat, fish, or legumes at every main meal to meet protein targets without relying solely on supplements
≈+150 kcal ≈+20g protein
Consider a fortified oral nutritional supplement drink (e.g. prescribed or pharmacy-available ONS) if food alone cannot meet protein targets — discuss with your GP or dietitian
≈+200 kcal ≈+18g protein
🍽️ Appetite strategies
Serve smaller portions more frequently — 5–6 small meals or snacks rather than 3 large ones
Eat calorie-dense foods first before filling up on lower-calorie items like vegetables
Offer cold or room-temperature foods if hot smells are off-putting or suppress appetite
Meal ideas
  • ·Greek yoghurt with granola, honey, and mixed berries
  • ·Baked salmon with roasted vegetables drizzled in olive oil
  • ·Lentil soup with a slice of buttered wholegrain bread
  • ·Full-fat cottage cheese with apple and walnuts
Reduced appetite is common with age. Small, frequent, energy-dense meals are the most effective strategy. Social eating where possible can also improve intake.

This tool provides general meal fortification suggestions for older adults and is not a substitute for a personalised nutritional assessment by a registered dietitian. For significant unintentional weight loss, a referral to dietetics is strongly recommended.

Health — Ageing

Meal Fortification Calculator

Malnutrition in older adults is a significant and underrecognised problem, often driven by reduced appetite, difficulty chewing, and the reduced caloric density of smaller meals. Meal fortification — adding energy and protein to existing foods without increasing meal volume — is one of the most practical dietary interventions available to carers and older adults themselves.

The importance of protein in older adults

Older adults have elevated protein requirements relative to younger adults due to anabolic resistance — the reduced efficiency with which muscle protein synthesis responds to dietary protein. The ESPEN guidelines recommend protein intakes of 1.0–1.2 g/kg/day for healthy older adults, rising to 1.2–1.5 g/kg/day for those with illness or injury. This is substantially higher than the general adult reference intake of 0.75 g/kg/day.

Inadequate protein accelerates sarcopenia (age-related muscle loss), increases fall risk, and impairs recovery from illness. Fortifying meals with protein-dense, low-volume additions — milk powder, eggs, cheese, yoghurt — is often more practical than increasing meal sizes for older adults with reduced appetite.

Frequently asked questions

What is an oral nutritional supplement (ONS)?

ONS are fortified liquid or semi-solid products (e.g. Ensure, Fortisip) providing a concentrated source of calories, protein, and micronutrients in a small volume. They are typically prescribed for malnutrition or high nutritional risk. A GP or dietitian can prescribe them on the NHS when clinically indicated.

 Should I be concerned if an older relative is eating very little?

Yes. Persistent poor appetite or unintentional weight loss in an older adult should prompt a GP visit. It may indicate treatable causes (dental problems, medications, depression, swallowing difficulties) or signal higher nutritional risk requiring dietetic input.
