Why do I eat when I’m not hungry, or get so hungry at night?

Three pages in this library are about food at the wrong hour. Pause and ask what you actually want before you eat is eating when you are not hungry. Eat enough in the daytime if you are hungry at night is hunger that feels like hunger. The decision happens in the shop is the evening craving and the cupboard. The first two start with a box that is not advice about habits at all, so it comes first here.

Constant or night hunger can have a medical cause, and an eating problem can look like a habit. Pause and ask what you actually want before you eat says it is the wrong page if you eat too little, find it hard to keep weight on, forget to eat, or your eating feels out of control. The UK’s NHS describes binge eating disorder as eating large portions of food until you feel uncomfortably full, with signs that include eating quickly, losing control during an episode and feeling guilty afterwards, and says that if you think you may have an eating disorder you should see a GP as soon as you can; treatment is usually talking therapy. In the UK, Beat’s eating disorder helpline is free: 0808 801 0677 in England (Scotland 0808 801 0432, Wales 0808 801 0433, Northern Ireland 0808 801 0434), 3pm to 8pm, Monday to Friday. In the US, ANAD’s free eating disorders helpline, 1-888-375-7767, is open Monday to Friday, 9am to 9pm Central Time, for support and referrals to treatment. If you are in crisis, call or text 988 in the US or call Samaritans on 116 123 in the UK, and in an emergency call 911 in the US or 999 in the UK. The helplines also take calls from people who are worried about someone else.

Hunger that keeps coming back can be medical. The US Centers for Disease Control lists increased thirst and hunger among the symptoms of diabetes. The NHS says type 2 diabetes is diagnosed with a blood test, that not everyone has symptoms, and that you should see a GP if you think you may have it. The NHS lists feeling hungry among the symptoms of low blood sugar, says low blood sugar is rare in people without diabetes, and says that if you do not have diabetes and get symptoms such as shaking, sweating, a fast heartbeat and feeling confused, you should see a GP. Some people say that hunger that keeps coming back at night may point to a condition such as reactive hypoglycaemia and not only to habit, and one person says it needs a diagnosis and that ignoring severe hunger could hide it. Some people say insulin resistance can drive overeating and suggest blood work. One person says ADHD can interfere with recognising hunger and fullness cues, one person says an assessment and treatment helped them make sense of boredom eating, and another thought it was ADHD and it turned out to be trauma. The ADHD and trauma points are both a doctor’s question. Some medicines raise appetite: the NHS lists wanting to eat more than usual as a common side effect of the antidepressant mirtazapine, and says not to stop it suddenly and to speak to your doctor first. Late eating can also bring on heartburn: the NHS advises not eating within 3 or 4 hours before bed to help manage heartburn and acid reflux, and says to see a GP if you have heartburn most days.

If you are hungry at night, check first whether you ate enough earlier in the day. Eat enough in the daytime if you are hungry at night says that if you did not, eat more at your day meals, with some protein in them, before you try to resist at night. It is for hunger that feels like real hunger at night, and it is the wrong page if your eating feels out of control, if eating more fills you with dread, or if you do not have enough food at home. Many people say night hunger is often what is left over from eating too little earlier: skipped meals, small meals, or meals light on protein. They say that eating more during the day, or adding protein to the day’s meals, took away much of the pull to snack at night. One person says that if you let yourself get very hungry during the day, you end up reaching for fatty and salty food at night, and suggests pairing carbohydrate with protein at your meals; another that skipping breakfast set up their night snacking and that adding protein to the morning helped; a third that cutting calories too sharply may be the cause. Some people say foods with protein and fibre keep them full for longer. The page does not say how much is enough: that depends on you, and if a doctor has given you a way of eating, that comes first. When the evening comes, the page offers a night of evidence and not a test of willpower: tomorrow, eat breakfast and lunch properly, with some protein in each, and have a proper dinner, then notice how hungry you are at ten at night.

When you eat is argued. Some people say that eating dinner later, or allowing a late snack, suited them better than forcing themselves to eat breakfast. One person says a bigger dinner earlier in the evening stopped the late hunger and that they then stop eating for the night; another says a bigger meal roughly an hour before bed stopped them waking up hungry. Those two point in opposite directions, and the page does not pick between them. One person says late eating gave them reflux that took months to settle and limited what they could eat; the page sets that beside the NHS’s 3 or 4 hours above. If you are still hungry after eating enough, some people say to eat a small snack so you can sleep, and some people say to wait, and that the hunger gets easier to sit through with practice, and one person says the urge passes by itself within a short time. The decider they name is whether the hunger is physical or habit, and how much it gets in the way of sleep. Waiting is not a fair test of your willpower if you have not eaten enough during the day. One person says a very small amount, such as a few almonds, was enough to let them sleep; another found that a small sweet portion made the urge stronger and not weaker.

If you are well fed and still reaching for food, pause for about three minutes and ask what you actually want. Pause and ask what you actually want before you eat says that when you want to eat and are not physically hungry, the three minutes can show whether it is company, rest or something to do and not food. Some people say a waiting period of about three minutes before you act on an urge lets the first impulse pass and shows whether you are really hungry or just have a passing craving. What people wrote does not say whether three minutes is special, or whether a different length would do as well. The pause is not a ban: after it, you can eat. One person says it is more realistic to go ahead and eat while doing something else, until you have other ways of coping, than to drop a go-to comfort overnight; another says to deliberately not do the habit once or twice and move your attention elsewhere. People differ on that, and the decider they name is how much discomfort you can stand and how far along you are. One person warns that holding the urge back without having built other ways of coping is unlikely to work, and one that shame does not help and self-kindness is what sustains change.

For the three minutes, many people say a glass of water first helps tell thirst from hunger. One person says sitting down and putting the food on a plate takes the autopilot out of it. One person says to do something with your hands: knitting, cross-stitch, gardening or painting your nails keeps the hands that would be eating busy. One person says the urge is often really about the mouth wanting something to do, and uses gum, floss picks or toothpicks, while another says gum led to dental problems that needed treatment. Some people use a rule: when you do not feel hungry enough to cook a proper meal, you are probably bored. It is one rule people use and not a test, and the page does not cover how to tell hunger from boredom in the moment without a doctor. It fails for anyone whose hunger signals are not working. Many people say food is often how people cope with loneliness, stress or boredom, and that dealing with the feeling, through therapy, mindfulness or company, works better than restricting food alone. One person says the core issue is loneliness and not hunger, and the answer is company that does not involve food, such as volunteering, meetups or joining a group; one person says that plating a home meal nicely and putting music on can make a meal alone feel less lonely. Some people say overeating can be linked to depression, or to growing up where food was scarce and waste was a fear, and not simply to a lack of control. People also disagree about whether this is mostly about what you eat or mostly about feelings; one person says it comes from poor food choices, too little fibre and protein, and habit, and can be fixed by changing what you eat and where you sit; another that it grows out of loneliness, depression or an addiction to food, and needs company or therapy. The decider people name is whether changing what you eat is enough on its own, or whether the feelings underneath need attention too.

The evening craving is decided earlier. The decision happens in the shop says the decision that matters happened in the shop, hours earlier, when you were fed and calm and it was easy. If it is not in the house, ten at night is an inconvenience, and inconvenience is enough. Shop straight after a meal, and look in your cupboards before you go. The page says the specific pull fades: people describe it dropping off sharply within a few days and being close to gone in a couple of weeks, so every craving you sit through is doing something rather than nothing. Its small tricks: a strong mint, mint gum, or brushing your teeth, which makes sweet food unappealing for a while; a hot drink such as tea, or cocoa powder in hot milk; and saying “I am choosing not to today” and not “I can’t have it”. The tooth caution comes with it: do not brush immediately after eating, and especially not after anything acidic like fizzy drinks, wine, citrus or sour sweets, because acid softens enamel for a while and brushing it in that state scrubs some of it off for good. Rinse your mouth with water instead, wait half an hour, then brush. One person says brushing does nothing for their cravings and leaves the hunger in place, which fits the night page: a stop sign does not feed you. On whether to cut a food out completely or plan it in, the page says people split hard: one camp says stop entirely for a few days, because each craving you do not act on weakens the loop and the whole thing quietens within a week or two; the other says a total ban makes the food enormous in your head and produces the binge it was meant to prevent, so count it, plan it and have it. What seems to separate them is whether a small amount satisfies you or starts something. The page also says some people found their cravings were plain hunger, or a dinner with too little protein in it, and that fixing the meal did more than any resisting afterwards. And if a craving is reliably attached to a particular feeling, the sweet thing may be doing a job, and taking it away without replacing the job it does is a plan with a hole in it.

If you live alone and the evenings are the problem, one person names libraries, parks, museums, farmers markets and church, one person says to cook for others or invite friends over, and one person points out that dance, cross-fit and cooking classes cost money, so they are not a free fix. Making friends from nothing is not covered. Join the club. Really. is the nearest page.

If there is not enough food at home, the answer is food help and not willpower, one person says. The Resource Bank entries below list food help in the US and the UK: SNAP, which helps you pay for groceries every month when money is tight and which you apply for through your own state; 211, a free call that connects you to local help with rent, food, bills, utilities and more; and, in the UK, Trussell, where you need a food voucher from a local community organisation to get a parcel with at least three days of meals.

Who these pages are not for. If you eat too little, or your eating feels out of control, the first box above is for you, and advice about eating less can be harmful or beside the point for someone who already struggles to eat enough. Left out on purpose, because they are ways of restricting and can hurt someone who already struggles with food: calorie counting, fasting and skipping meals, fasting windows, fixed cut-off times for eating, a deliberately dull diet, undercooked food, smaller plates to eat less, a plan to throw food away, and treating hunger as a sign of progress. One person says strict cut-offs such as no food after a set hour can themselves look like disordered eating, and suggests eating on a regular schedule every few hours instead. If your night hunger began after you stopped drinking alcohol, some people link sugar cravings to that; the pages do not cover it, and a doctor can. Not covered: managing hunger on shift work, what to do when the urge comes at work, how to handle pressure to finish your plate in company, and long-term upkeep. What people wrote is mostly from people who found something that worked. The pages do not diagnose anything, and no one’s experience here predicts yours.
