First, the important bit: this is a food guide, not medical advice. If a medicine or a health condition is affecting your appetite, your prescriber and GP lead on your health, and if they've given you specific dietary advice, that wins. If you feel sick, have stomach problems that don't go away, or are struggling to eat or drink, talk to your GP or pharmacist, and call NHS 111 if you're worried. If you take insulin or other diabetes medicines, ask your diabetes team about low blood sugar when you're eating less.
What follows is the practical meal-planning side, which many people with a small appetite don't get much help with.
A different kind of food problem
Most food advice assumes the problem is eating too much. When your appetite is small, it's the opposite: the challenge isn't eating less, it's making the little you do eat count.
When you eat less, you take in less of everything: calories, yes, but also protein, fibre and vitamins. And when protein drops too low while you're losing weight, more of the weight lost can come from muscle rather than fat. That matters for strength and for how you feel day to day.
So a good rule of thumb is simple to say and hard to wing: protein first, every meal, even the small ones.
Protein first, in practice
You have less appetite to spend, so spend it on the most protein-dense foods before anything else on the plate:
- Eggs — 6g protein each, gentle, cheap, endlessly flexible
- Greek yogurt (strained, not "Greek style") — about 10g protein per 100g; a small bowl does real work
- Cottage cheese — around 11g per 100g, soft, mild, easy on days when nothing appeals
- Chicken thighs — batch-cook once, pick at them across several meals
- White fish and tinned tuna — light, high-protein, quick
- Lentils and beans — protein plus the fibre that helps everything keep moving
A useful habit: get your protein in before you're full, not after. Yogurt before toast. Chicken before rice. It sounds trivial, but it can make a real difference when your appetite runs out three-quarters of the way through a plate.
Small, planned and gentle beats big and ambitious
When you're not hungry, a portion that used to look normal can look like a wall. What tends to work instead:
- Smaller, protein-dense meals spread across the day, rather than two or three large ones
- Batch-cooked food in the fridge — on low-appetite days, reheating a small portion of something you already trust beats deciding, shopping and cooking from scratch
- Cold, plain options on queasy days — yogurt, cottage cheese, boiled eggs, crackers and tuna. Have them in the house before you need them.
- Fluids and fibre, deliberately — both fall quietly when you eat less, and both are worth planning rather than hoping for
Why planning beats tracking here
Many food apps were built for the old problem: log everything, stay under a ceiling. With a small appetite the ceiling often looks after itself. The more useful thing to plan is a floor: meals decided in advance, so protein is built in before your appetite gets a vote.
That's the approach Plan X Prep takes. Every plan is built around your calorie and protein targets, with protein treated as a floor, not a ceiling. The app also has a protein-first macro preset (40% protein, 35% carbs, 25% fat). Meals come from a 1,500+ recipe library costed at real UK supermarket prices, so the week is decided and portioned, with an estimated cost, before you shop.
No logging, and less guessing about protein on low-appetite days. The plan does the arithmetic in advance; you eat what you can.
The bottom line
A small appetite changes the job of food: from cutting back to making every bite count. Protein first, small planned meals, gentle options ready for the hard days, and your GP's advice above all of it.

Frequently asked questions
- What should I eat when I have no appetite?
- Prioritise protein-dense, low-effort foods you can eat in small amounts: strained Greek yogurt (about 10g protein per 100g; 'Greek style' tubs usually have less), cottage cheese (around 11g per 100g), eggs (6g each), tinned tuna and batch-cooked chicken. Cold, plain options tend to be easier on queasy days. If you're struggling to eat or drink, talk to your GP or pharmacist.
- Why does protein matter more when you're eating less?
- Eating less naturally lowers your intake of everything, including protein. If protein falls too low while you're losing weight, more of the weight lost can come from muscle rather than fat. Planning protein into meals in advance helps guard against that. Your GP or a dietitian can tell you how much is right for you.
- Is there a UK meal planning app for small appetites?
- Plan X Prep plans your week around your calorie target with protein treated as a minimum, and has a protein-first macro preset (40% protein, 35% carbs, 25% fat). Meals are costed at real UK supermarket prices. It's a meal planning tool, not medical advice.
