A home plan for overeating in dementia care has four steps: serve smaller portions, hold back half for a second sitting, start with soup, and add fullness with vegetables or salad. Eat with the person, replace sweets with fruit and lower-calorie options, and add daytime activity to reduce boredom eating. Overeating here means eating again after forgetting a meal, seeking specific foods, hoarding food, or eating unsuitable items. It can affect many types of dementia, but compulsive overeating with strong sweet and high-fat preference is especially linked to behavioral-variant frontotemporal dementia.

Why does overeating happen at home?
UCLA Health notes that people with dementia may forget they already ate or worry where the next meal will come from. The same guidance notes some people eat unsuitable or non-edible items. The Alzheimer Society of Canada links overeating to forgotten meals, cravings for specific foods, food hoarding, boredom, or depression, and recommends shared meals plus engaging daytime activities, described in Alzheimer Society of Canada meal-time guidance.
Eating together gives a calm cue about timing and amount. The Association for Frontotemporal Degeneration reports compulsive overeating and preference for sweet, high-fat foods are especially common in behavioral-variant frontotemporal dementia. Its summary of the 2025 ALLFTD Consortium study puts this at about 50% early and 60% later.
How can portions calm constant hunger?
Smaller plates reduce intake without a long talk about limits. Splitting one meal into two sittings works well when the person asks for more soon after eating.
This approach comes from dementia nutrition guidance from Kent Community Health NHS Foundation Trust, detailed in the Kent Community Health dementia and nutrition leaflet. It adds volume with fewer calories and keeps the routine steady.
- Serve a small first plate and keep the second half back.
- Start with soup to add early fullness.
- Offer a larger serving of salad or cooked vegetables.
- Clear extra bread, sweets, and large packages from the table.
- Repeat the same order at the next sitting.
What foods help with sweet cravings?
Keep fruit or another healthy snack ready and avoid stocking large amounts of sweets. Alzheimer's Society UK advises substituting high-calorie foods with lower-calorie versions for the same reason, explained in Alzheimer's Society UK advice on constant eating. Build daily meals around vegetables, fruits, whole grains, low-fat dairy, and lean protein.
Cut refined sugars, and use fruit or juice-sweetened options for a sweet tooth, as the Alzheimer's Association eating tip sheet advises. Try sliced apple with peanut butter, berries with plain yogurt, or warm pear with cinnamon. Keep portions ready in small bowls so a second helping stays small by design.
When is it more than appetite?
Increased appetite is often temporary, so watch the pattern for one to two weeks. Track weight, thirst, urination, energy, coughing, choking, pocketing food, or stuffing the mouth. Seek prompt review for steady weight gain, blood-sugar changes, repeated coughing or choking, or mouth-stuffing.
Ask a clinician, dietitian, or speech-and-language therapist before tightening food restriction, since Frimley Health NHS advises swallowing referral for coughing or choking. Bring a short log with meal times, repeat requests, foods taken, and any choking or distress. Ask whether medication, mood, pain, sleep, or swallowing changes explain the shift.
