My food has run out – help is still days away

Supplies are gone and help is days away. Now it is about saving energy, staying safe and eating only what is truly safe.

First

  1. Stay calm: a healthy person can get through several days without food if they drink enough and stay warm. Water comes first.
  2. Save energy: little exertion, plenty of rest, stay warm and dry – being cold burns a lot of energy.
  3. Do not eat anything you cannot identify with complete (100 %) certainty. Poisoning is far more dangerous in the wild than hunger.
  4. Share out remaining supplies fairly and openly; if possible, tell rescuers via 112 that food has run out.

Call emergency services if

  • No drinking water
  • Dizziness, fainting or severe weakness
  • Children, pregnant people or sick people (e.g. diabetes) without food
  • Suspected poisoning after eating plants, mushrooms or shellfish (also contact a poison centre)
  • Signs of hypothermia

What is happening

A trip lasts longer than planned, a change in the weather traps you or the rescue is delayed: at some point the last piece of bread is eaten. Your stomach rumbles, your mood sinks and the thought of food becomes overwhelming. It is exactly at this moment that the most dangerous mistakes happen – trying unknown berries or mushrooms, for example.

Medically, a few days of hunger are rarely dangerous for a healthy adult as long as they drink and stay warm. However, strength, concentration and tolerance of cold decline noticeably after a few days, and decisions become harder. So it is important to save energy and keep a clear head.

Foraging costs energy. It only pays off if the yield is safe and easy to reach: known plants in quantity, nuts in autumn, fish in a body of water. Trapping is prohibited in Austria and Germany without hunting rights and should only be considered at all in genuine danger to life; the chances of success are low and the risk of injury to people and animals is high.

When water is short, an important rule applies: whoever has little water should also eat little – especially little protein, because digestion needs water. Water always comes before food.

Step by step

My food has run out – help is still days away – Phase 1 of 4Straight away. Count the remaining supplies and divide them openly – including small items such as sugar, tea and stock cubes. Tell rescuers via the emergency number or agreed contacts that food has run out, especially if children, pregnant people or the sick are present. Secure the water supply and set a drinking plan – this is now more important than food. Reduce energy use: no unnecessary walking, rests out of the wind, put on warm clothing early.
Phase 1 of 4

Phase 1 of 4

Straight away

Count the remaining supplies and divide them openly – including small items such as sugar, tea and stock cubes. Tell rescuers via the emergency number or agreed contacts that food has run out, especially if children, pregnant people or the sick are present. Secure the water supply and set a drinking plan – this is now more important than food. Reduce energy use: no unnecessary walking, rests out of the wind, put on warm clothing early.

The animation shows the key actions of each phase schematically; the text below is what counts.

  1. Phase 1

    Straight away

    • Count the remaining supplies and divide them openly – including small items such as sugar, tea and stock cubes.
    • Tell rescuers via the emergency number or agreed contacts that food has run out, especially if children, pregnant people or the sick are present.
    • Secure the water supply and set a drinking plan – this is now more important than food.
    • Reduce energy use: no unnecessary walking, rests out of the wind, put on warm clothing early.
  2. Phase 2

    The first days

    • Only gather what you know without any doubt and whose poisonous look-alikes you can rule out – e.g. stinging nettle, dandelion, blackberry, raspberry, hazelnut.
    • Do not eat mushrooms at all unless you are a trained expert – deadly species look very similar to edible ones.
    • Always wash what you gather thoroughly and cook it where possible; in areas with fox tapeworm, eat things gathered close to the ground only when cooked.
    • By water, fish with a line or improvised hook if it is a genuine emergency; always cook fish thoroughly.
    • Insects and worms provide protein; eat them only cooked, and avoid brightly coloured, hairy or stinging ones.
  3. Phase 3

    If it takes longer

    • Fixed daily structure: rest in the midday heat or the cold, short gathering rounds close to camp.
    • Traps only if you can build them correctly, it is a genuine threat to life and you check them regularly; afterwards dismantle every trap completely.
    • Lean meat alone does not cover energy needs – fat and carbohydrates (nuts, roots) are just as important.
    • Watch for warning signs: dizziness on standing up, confusion, extreme weakness – then call the emergency number again.
    • Look after morale: small goals, celebrate successes, talk to each other.
  4. Phase 4

    After the rescue

    • After a long period of hunger, eat again slowly and in small portions; after more than a few days without food, seek medical advice.
    • If you have symptoms after eating wild plants, mushrooms or shellfish, contact a doctor or poison centre and say what was eaten.
    • Remove traps, cords and leftovers from the terrain completely.
    • Think about what should go into your emergency rations in future.

★ Pro tips

What experienced people do differently: proven practice from mountain rescue, fire services, lifeguards and civil protection that beginners rarely know.

  1. Melt snow, don't eat it

    Snow in your mouth chills you from the inside and costs your body energy to warm it up – energy you can't spare without food. Melt it in a pot or in a bottle kept close to your body, then drink the water.

  2. A bite before sleep keeps you warmer

    If you still have something, eat a small, ideally fatty portion just before the cold night rather than in the morning. Digestion produces heat and fat gives long-lasting energy. Only do this while you have enough water.

  3. Eat the perishables first

    Fresh food like bread, cheese or fruit goes first; long-lasting items such as nuts, bars and sugar are kept for later. A little sugar in reserve helps when you need one more effort – such as walking out with rescuers.

  4. Hot water takes the edge off hunger

    Hot water, tea or a stock cube fill the stomach, warm you and lift your mood. It doesn't replace food, but it makes the wait noticeably easier. Spread these small comforts over the day.

  5. Hunger makes for poor decisions

    On an empty stomach people get impatient, irritable and take more risks. Make big decisions (moving on, crossing a stream, foraging) calmly and talk them through out loud in the group. If you're alone, ask yourself: would I do this on a full stomach?

What to watch out for

  • Poisonous look-alikes

    Wild garlic and lily of the valley or autumn crocus, cow parsley and hemlock, bilberry and deadly nightshade: many deadly plants look like edible ones. When in doubt, never eat. The often quoted “universal edibility test” does not protect against deadly poisonous plants.

  • Yew

    Yew looks vaguely like spruce and fir but almost all parts are deadly poisonous. For needle tea use only spruce or pine that you can identify with certainty.

  • Shellfish and algal blooms

    Shellfish can accumulate algal toxins that cooking does not destroy. Do not gather during algal blooms, in discoloured water or near sewage outfalls.

  • Raw meat and wildlife diseases

    Wild meat can transmit Trichinella or tularaemia. Work with gloves or a cloth, wash hands, always cook meat and fish thoroughly. Never eat animals found dead.

  • Law and animal welfare

    Fishing without a licence and trapping without hunting rights are prohibited in Austria and Germany. In genuine danger to life, necessity may play a role – but that does not replace the everyday rules and never justifies cruelty to animals.

Common mistakes

  • Trying unknown berries, plants or mushrooms out of hunger.
  • Eating a lot when water is short, especially protein.
  • Spending hours gathering that costs more energy than it yields.
  • Setting traps and not checking or not dismantling them.
  • Eating fish or meat only half cooked.
  • Sharing out supplies secretly or unequally.

Prepare in advance

  • Always carry emergency rations that cover an extra day (nuts, bars, dried fruit).
  • Learn a few reliably identifiable wild plants of your region on a course or with a field guide – and the most dangerous poisonous plants.
  • Put a mini fishing kit and cord in your emergency kit and find out about fishing law.
  • Pack a pot or mug for cooking – cooking is what makes much of what you gather safe.
  • Save the number of your poison information centre (Austria: +43 1 406 43 43).
  • Plan trips so that a buffer day of food and water is in your pack.

Special consideration

Children
Children have fewer reserves and like to put berries in their mouths. Give supplies to them first and say clearly: eat nothing without asking.
Diabetes and other conditions
Anyone taking insulin or blood-sugar-lowering medication can become dangerously hypoglycaemic without food. Reserve glucose for this person and mention it in the emergency call.

Basics for this situation

Why: Always applies to this situation – regardless of your answers.

All rules of this situation (12)
  1. [not active] If Season = Spring / summer

    In spring and summer a few easily recognised plants are available. Collect only species you know without any doubt, and rule out poisonous look-alikes.

  2. [not active] If Season = Autumn

    In autumn nuts and beechnuts provide a lot of energy. Acorns must be leached thoroughly before eating; beechnuts only in small amounts.

  3. [not active] If Season = Winter

    In winter there are hardly any edible plants. Keeping warm saves more energy than foraging gains. Needle tea warms – yew is deadly poisonous.

  4. [not active] If Environment = By a lake or river

    Waters are often the best source of food. Fishing normally requires a licence; without a genuine emergency, fishing law applies in full.

  5. [not active] If Environment = On the coast

    On the coast: watch the tides, take shellfish only from clean water and never during an algal bloom, eat seaweed only in moderation. Never drink seawater.

  6. [not active] If Environment = Mountains

    Little food can be found in the mountains. Better to save strength for descending or waiting than to forage on steep ground.

  7. [not active] If Equipment = Fishing line and hooks

    Fish with a hand line at calm spots, bank edges and inflows; always cook fish thoroughly.

  8. [not active] If Season = Winter and Equipment = Fishing line and hooks

    Ice fishing only on ice that is reliably strong enough – when in doubt, stay off the ice.

  9. [not active] If Equipment = Knife and cord

    Traps are prohibited in Austria and Germany without hunting rights and should only be considered at all in genuine danger to life. They rarely catch anything; if used, check them regularly, kill animals at once and dismantle every trap.

  10. [not active] If Equipment = Pot / fire possible

    Cook everything you gather thoroughly – insects and worms too. Without a pot, you can cook with hot stones.

  11. [not active] If Equipment = Almost nothing

    Without equipment, foraging rarely pays off. Rest, warmth and water are more important.

  12. [not active] If Who is with you? = Group

    Count supplies openly and divide them equally; look after children, the sick and older people first. Arguing costs strength.
