When appetite and digestion change: eating, drinking, moving and resting

When appetite or digestion changes, the most sensible thing is usually to pause and listen to what the body is asking for, rather than carrying on regardless. A cold, a long journey, weeks of stress, a new work pattern or a freshly started diet can all alter how hungry you feel and how meals sit with you. There is no single recipe, but there are a handful of ordinary habits that help in almost any phase like this.

A good starting point is to ask yourself three questions at the end of the day: have I eaten enough, have I had enough to drink, and have I slept as much as I need? Going over the answers for a few days makes patterns visible without making a drama of it.

When you do not feel like eating

With a small appetite, the usual plate can look like a mountain. It is often easier to serve less and go back for more if there is room, or to spread the day's food over several small occasions instead of three large ones. Simple dishes such as broth, plain boiled rice, an omelette, yoghurt or ripe fruit ask little of the digestion and tend to go down better than elaborate meals.

It also helps to make the little that goes in count: add some protein (an egg, cheese, pulses, fish) and avoid letting many hours pass without eating anything. Eating slowly, away from screens and without forcing yourself to clear the plate makes it easier to notice when you have had enough.

When your stomach feels heavy

A feeling of heaviness or bloating sometimes eases with small changes. Very fatty food, fried dishes and rich sauces take longer to digest, so on those days lighter cooking, such as grilling, baking or boiling, is a kind choice. Fibre from fruit, vegetables, oats and pulses is a friend to the gut, provided it is added little by little and with fluid; raising it all at once tends to bring wind.

Water goes down more easily in small sips spread across the day than in one enormous glass. Broths, soups, juicy fruit and unsweetened tea count as well. After a meal, a short, easy walk, and spending a while sitting or standing rather than lying down straight away, usually feel better.

When energy runs low

Tiredness rarely has a single cause. Before looking for complicated explanations, check the basics: if you have eaten less than usual, drunk little or slept badly, any one of the three is enough to leave you drained. Keeping regular sleeping hours, having a lighter evening meal earlier and putting screens away at night all help you rest better.

On flat days it is reasonable to ask less of yourself: a walk instead of a hard workout, short breaks during the day, some natural light. Gentle movement usually feels better than staying completely still, but nothing needs forcing.

Signs that it is worth speaking to a health professional

Everyday habits are not a substitute for an assessment, they promise no relief and they do not suit every situation. Speak to a health professional if any of the following appears:

• vomiting that does not stop, or being unable to keep fluids down;
• severe abdominal pain;
• signs of dehydration, such as intense thirst, a very dry mouth, scant dark urine, dizziness on standing or a racing heartbeat;
• weight loss with no explanation;
• a high temperature, or blood in vomit or stools;
• symptoms that last for several days or get worse instead of better.

The same goes for anyone with diabetes, pregnancy or a digestive condition who wants to change how they eat: in those cases, individual advice comes first.
