Poor appetite after 70: how to eat enough during the day

Lunch is on the table and after five or six mouthfuls it simply stops going down. Past 70 the appetite tends to fade quietly, so the problem is often spotted only when the belt moves in a notch or the stairs start feeling steeper. This is the practical side of it: how to get enough food and protein in across a day when hunger no longer shows up by itself.

Why appetite fades with age

Several things happen at once. The stomach empties more slowly, so fullness arrives sooner and hangs around longer. Hunger signalling weakens too, which means the body stops asking for food even when it needs it.

Then there are the senses. Smell and taste dull with age, and food that tastes of nothing is food nobody wants. Plenty of common medicines dry the mouth, alter taste or cause mild nausea — not a reason to stop taking them on your own, but very much a reason to mention it to the doctor who prescribed them.

The rest is daily life: sore teeth or dentures that no longer fit, less moving about and therefore less energy burned, cooking for one, eating alone. Grief and withdrawal after losing a partner knock the appetite down hard, more often than anyone admits.

How much food and protein you actually need

A workable target for protein after 70 is 1.0 to 1.2 g per kilogram of body weight per day — roughly 75 to 85 g for someone weighing 70 kg. That is higher than the old advice, because an older body responds less strongly to the protein in a meal and needs a bigger dose for the same effect.

Spacing matters as much as the total. The evidence is strongest for putting 25 to 30 g of protein into a single meal, three or four times a day, rather than saving it all for dinner. In real food that is about 100 g of roast chicken, a piece of white fish with an egg, or 200 g of Greek yoghurt with a handful of walnuts.

For total energy, a rough range is 25 to 30 kcal per kilogram a day. You do not need to count it. The scales are the better guide: weigh yourself once a week, in the morning, under the same conditions, and watch the trend over a month. If the number drifts down and you did not plan it, you are eating too little. Grip strength is a useful second check — when it drops noticeably, muscle is usually going with it.

Five or six chances to eat, not three

If not much fits into one sitting, use more sittings. Three main meals plus two or three smaller occasions deliver the same daily intake without anyone having to force a plate down.

Eat by the clock rather than by hunger. Waiting to feel hungry often means waiting all day. Fixed times — say 8, 10.30, 1, 4, 7 and something small before bed — work better than waiting for a signal that has stopped being reliable.

For most people appetite is best in the morning and tails off through the day, so put the biggest meal early. Watch the fluids as well: a glass or two of water half an hour before a meal fills the stomach and kills the appetite outright. Drink between meals, and keep to what you need to help the food go down.

Smaller portions have to be denser

The aim is not a fuller plate. It is more nourishment in the same volume.

Calories that take up no room

A tablespoon of olive oil over vegetables or stirred into soup adds around 120 kcal and changes nothing about the size of the meal. A handful of almonds is about 180 kcal, a tablespoon of peanut butter about 95. Full-fat yoghurt, milk and cheese instead of the reduced-fat versions are an advantage here, not a failing.

Liquid calories go down more easily than solid ones. Porridge made with milk instead of water, an egg beaten into hot soup, a drink of milk with banana and a spoon of peanut butter — these get through on days when a plate does not. Just keep them alongside or after a meal rather than in place of one.

When food tastes of nothing, or chewing hurts

If flavour has flattened, build it back without leaning on salt: lemon, vinegar, garlic, herbs, smoked paprika, a bit more fat. Contrast helps too — something hot with something crisp alongside it.

If teeth or dentures are the problem, change the form of the protein rather than dropping it: minced meat, fish, eggs, yoghurt, pulses, meat slow-cooked in sauce. A dry mouth needs sauces and a sip of water with each mouthful.

Preparation is often the real barrier. When arthritic fingers make gripping and holding painful, peeling and chopping turn into an afternoon's work, and the day ends on tea and a biscuit. Ready-prepared vegetables, a tin of tuna or beans, and one bigger cook-up a week solve more than any general advice about healthy eating.

Moving about brings the appetite back

This is the part that usually gets skipped. People who move eat more, with no trick involved: spending more energy pulls intake up behind it. Regular walking of 20 to 30 minutes, ideally before lunch, restores at least some of the hunger for a lot of people.

The second reason matters more. Protein on its own does not build muscle; it needs a stimulus. Two strength sessions a week, even modest ones, are what send the food you have eaten into muscle rather than nowhere. If standing is difficult, a seated exercise programme is a perfectly reasonable place to start.

When to see a doctor

A poor appetite is not always a matter of habit, and some versions of it need looking at. Book an appointment if you have unintentionally lost 5% of your body weight over six months (3.5 kg for someone of 70 kg), or two to three kilograms in a month.

The same applies if the appetite disappeared suddenly, or if there is pain or sticking on swallowing, vomiting, blood in the stool, persistent nausea or an unexplained temperature. If the loss of appetite started within weeks of a new medicine, say so — the dose or the timing can often be adjusted.

Mention it too if low mood, poor sleep and pulling away from people came along with it; in later life depression frequently shows up on the plate first. A doctor can also check the things you cannot assess yourself, such as thyroid problems or poor vitamin B12 absorption. A dentist belongs in this conversation just as much as the GP.

The short version

• Aim for 1.0 to 1.2 g of protein per kilogram a day, split into 25 to 30 g per meal, three or four times.
• Eat by the clock, five or six times a day, with the largest meal in the morning or around midday.
• Do not drink large amounts in the half hour before a meal; drink between meals instead.
• Make food denser: oil, nuts, full-fat dairy, porridge made with milk rather than water.
• Weigh yourself weekly; an unintended 5% loss over six months is a reason to get checked.
