What to do when a senior with dementia won't eat?

The short answer

Follow the 2024 ESPEN guideline's core principles: individualize care, offer attractive food and drinks with real choice in a calm, appealing setting, screen routinely for malnutrition and dehydration, and use oral nutrition support once reversible causes are addressed. The guideline advises against dementia-specific supplements and ketogenic diets as therapy — and against omega-3 pills (while encouraging omega-3 foods like salmon and chia).

What the ESPEN guideline says (2024 update)

ESPEN's 2024 guideline on nutrition and hydration in dementia provides evidence-based recommendations to prevent and treat malnutrition and dehydration, built around individualized approaches. Key recommendations extracted from the guideline:

Offer attractive food and drinks with choice, in a functional and appealing environment.
Screen routinely for malnutrition and dehydration; assess and monitor closely.
Use oral nutrition support after eliminating potential causes of poor intake.
Limit what the evidence does not support: dementia-specific oral nutrition supplements, ketogenic diet as a therapeutic intervention, and omega-3 supplements in pill/capsule form. Dietary omega-3 foods (salmon, chia seeds) are encouraged.
Avoid appetite-stimulating agents as a routine approach.

Practical tips for caregivers

🍽 Small, frequent, familiar

Offer 5-6 smaller eating occasions with foods the person has always enjoyed, rather than three large meals.

🎨 Make it appealing

Color contrast on the plate, familiar textures, pleasant smells and a calm table — the guideline's "attractive food with choice" in action.

⚖️ Watch weight, not just appetite

Weigh regularly and watch for signs of dehydration — screening matters because weight loss is often silent.

🥤 Soft, energy-dense options

When chewing or appetite is an issue, smoothies, congee and soft bites can keep intake up.
