Loss of appetite in depression is common, and so is overeating. Why does appetite change, when does weight change matter and how can you protect your meals?
Imagine a twenty-nine-year-old engineer living alone in Ankara. For the past two months, she has been opening the fridge, looking at what is inside and closing it again. She gets through the day on a few crackers and a glass of tea in the evening. When her mother asks on the phone, "Your voice sounds so faint, are you eating?", she says, "I am, Mum." In the same city, someone else is going through the opposite: at midnight he goes to the kitchen and finishes a packet of biscuits without really noticing what he is eating, then is angry with himself in the morning. Although the two pictures look like opposites, they can grow from the same root. Loss of appetite in depression and increased appetite are both common changes. In this article I explain why appetite changes in depression, which signs need attention and the small but effective steps you can take to protect your eating.
How Does Depression Affect Appetite?
Appetite is not only about whether your stomach is empty. When we get hungry, what we crave and how much we enjoy food are the shared product of the brain's reward, stress and energy-regulation systems. Since depression affects all of these systems, it is not surprising that appetite changes too.
In the diagnostic criteria for depression, changes in appetite and weight appear in both directions: in some people appetite decreases markedly and weight loss occurs; in others appetite increases, a pull towards sweets and pastries becomes noticeable, and weight gain occurs. The same person may also experience different pictures in different depressive episodes.
There is another reason this change matters: appetite is one of the most concrete indicators of mood. Sometimes, without noticing their own emotional state, a person says, "Lately I don't feel like eating anything" or "In the evenings I can't stop myself." These sentences are important clues in an assessment.
What is more, the two extremes can appear on the same day. Someone who cannot get anything down in the morning and skips lunch may eat uncontrollably in the evening as hunger and tiredness combine. The regret that follows leads to the decision "I won't eat anything today" the next morning, and the cycle begins again. That is why, when assessing a change in appetite, it is necessary to look not only at how much is eaten, but also at what time of day and with what feeling.
Why Does Loss of Appetite in Depression Happen?
Several mechanisms work together behind a decrease in appetite.
Less enjoyment from food
One of the core symptoms of depression is being unable to enjoy things that used to bring pleasure. Food is one of those things. Even your favourite dish may taste bland, "like cardboard". When food stops being a pleasure and becomes a burden, it becomes easier to skip it.
The effect of the stress system
Intense stress and anxiety put the body into a kind of alarm state. In this state, digestion takes a back seat; the stomach knots up, the throat feels as if it is closing, and nausea may be felt. If depression is accompanied by anxiety, loss of appetite may be more pronounced.
Loss of energy and motivation
Eating requires a series of small steps: shopping, preparing, cooking, sitting down at the table, washing up. In depression, each of these steps can feel heavy. The person is actually hungry, but because preparing a meal looms so large, they skip it. This is especially noticeable in people who live alone. I discuss the difficulties in other areas of self-care, such as showering and housework, in the article on struggling with self-care in depression.
Thoughts of worthlessness and "not deserving"
For some people, eating is perceived as a form of looking after themselves, and it is neglected along with the thought "I'm not worth it." This can be seen especially in depressions involving intense self-criticism.
Why Does Appetite Increase in Depression?
Increased appetite is at least as common a face of depression as loss of appetite, but it is usually talked about less, because the person sees it as a willpower problem and feels ashamed.
When food becomes a tool for regulating emotions
Sweets, pastries and fatty foods stimulate the brain's reward system quickly and briefly. In a low mood, this short relief is very tempting. Food suppresses emptiness, loneliness or boredom for a few minutes. The guilt and regret that follow, however, drag the mood down further, and the cycle starts again. If you would like to understand this pattern in more detail, take a look at the article on emotional eating. I would also add that emotional eating can happen to anyone from time to time, but when it becomes more frequent alongside depression, it needs to be addressed in its own right. The problem here is not eating itself, but the job that food has taken on.
Tiredness and the search for quick energy
The tiredness of depression can push the body towards foods that give quick energy. Especially during periods when sleep is disrupted, the systems that regulate hunger and fullness signals are also affected; the person gets hungry more often and feels full less easily.
Evenings and night-time
Increased appetite usually concentrates at certain times of day. A day that somehow passes with work or responsibilities becomes heavier in the evening when you are alone. Snacks eaten in front of the television or while scrolling on the phone become a way of filling that emptiness.
Appetite is often the voice not of the stomach, but of how the day has gone.
How Appetite Changes Show Up in Daily Life
Changes in appetite and weight are not only a personal experience; the people around us notice them too and often comment. In Turkey, the shared table is an important expression of love and belonging. That is why someone with no appetite often faces insistence such as "Just have a bite of something" or "How can you eat so little?" Although this insistence comes from love, it can create pressure and guilt in the person.
Weight change is also a visible subject. Comments at Bayram holiday visits, weddings or family meals such as "You've lost so much weight, are you ill?" or "Look at you, you've put on weight" can touch the wounds of someone who already feels bad. As a result, the person may start avoiding family gatherings and eating alone, which in turn increases loneliness.
For those who live alone, things get heavier in a different way. When no one calls you to the table, meals easily disappear. Food delivery apps, ready-made food and irregular hours make both loss of appetite and overeating easier. In periods when the high cost of living makes grocery shopping harder, the quality of eating can drop even further; cheap and filling but less nourishing foods come to the fore.
How can loved ones help at the table?
Looking at the plate of a loved one with depression and saying "You haven't eaten anything" increases the pressure on them, however well meant it is. Instead, it is more reassuring not to put food at the centre of the meal and to steer the conversation elsewhere. Preparing a small amount of a dish they like, and making small offers that give them a choice instead of saying "Eat", such as "I'm making tea; would you like a slice of bread and cheese with it?", works well. Comments about weight and body should be avoided, especially in front of others. The same principle applies to someone struggling with overeating: instead of criticism and bans, an evening walk together or a calm, screen-free dinner at the table is far more supportive.
Coping with Loss of Appetite in Depression and Overeating
For someone with loss of appetite in depression and for someone whose appetite has increased, the basic principle is the same: routine and compassion. Waiting for appetite to come back before sorting out your eating usually does not work. Here too, behaviour comes first; appetite and enjoyment often follow.
For loss of appetite
- Eat by the clock, not by hunger. Set fixed times during the day for three main meals and one or two snacks, and put reminders on your phone. When hunger signals weaken, the clock becomes a guide.
- Start with small portions. A full plate can be daunting. Putting a small amount of food on a small plate creates the feeling "I can finish this."
- Make a list of effortless foods. Keep easy-to-prepare, nourishing options at home such as yoghurt, cheese, eggs, simit (a sesame bread ring), fruit, nuts and boiled chickpeas. Have a ready "plan B" for days when you do not have the strength to cook.
- Don't neglect fluids. If solid food will not go down, liquid options such as soup, ayran (a salted yoghurt drink) or milk can be a start. Keep track of how much water you drink, too.
- Don't always eat alone. If possible, eat a few meals a week with a relative, a friend or at the family table. A shared table can turn food back into a social and meaningful experience.
For overeating
- Don't punish yourself. Strict diets and going hungry can lead to an even greater loss of control in the evening. Regular meals are the foundation for reducing episodes of overeating.
- Notice your trigger times. For a week, note when and what you eat and how you feel at that moment. Most people notice that overeating comes at certain times and with certain feelings, such as loneliness or boredom.
- Create a pause. When you head for the kitchen, ask yourself, "Am I hungry right now, or do I need something else?" Sometimes calling a friend, a short walk or a warm shower can take the place of the relief food provides.
- Arrange your surroundings. Putting snacks out of sight, eating food from a plate at the table and avoiding eating from the packet in front of a screen reduce the amount you eat without your noticing.
When Should You Seek Professional Support?
A change in appetite on its own does not mean a diagnosis; however, in the following situations it is important to see a professional and, where necessary, a doctor:
- If there is marked and unintended weight loss or weight gain in a short time
- If for days you have barely been able to eat or drink enough fluids
- If the change in appetite is accompanied by low mood, loss of enjoyment, hopelessness or intense tiredness
- If there are eating episodes you cannot control, followed by compensatory behaviours such as vomiting, excessive exercise or going hungry
- If thoughts about your weight and body take up most of your day
- If thoughts that life is meaningless, of dying or of harming yourself cross your mind; in such a situation, if you do not feel safe, call 112 (emergency services) without delay
A doctor's assessment is also important to rule out physical conditions that can change appetite and weight, such as thyroid problems, diabetes or digestive diseases. A medicine you are taking may be affecting your appetite; in that case, talk to your doctor rather than stopping it on your own.
How Are Appetite Changes Addressed in Therapy?
In therapy, a change in appetite is addressed as part of the overall picture of depression. In cognitive behavioural therapy, an eating and mood record is kept first; it makes visible at which times, with which emotions and with which thoughts eating decreases or increases.
If loss of appetite is in the foreground, a regular meal plan comes up as part of behavioural activation. Small steps to make preparing food easier are planned, and an effort is made to bring the shared table back into life as a social activity. Thoughts such as "I'm not worth it" or "What's the point of eating?" are examined.
If overeating is in the foreground, we explore together which emotional need the food is meeting. Other ways of coping with feelings such as loneliness, emptiness or anger are developed. Instead of the cycle of self-blame and strict dieting, an effort is made to build a kinder and more regular approach. If there are signs of an eating disorder, the assessment and treatment plan are shaped accordingly; where necessary, there is collaboration with a doctor and a dietitian.

Frequently Asked Questions
Should I force myself to eat when I have no appetite at all?
Rather than forcing yourself through large portions, eating small amounts at regular times is a more workable approach. Easily digested, nourishing options are a good place to start. If you have barely been able to eat anything for days, it is important to see a doctor.
Is it normal to gain weight with depression?
In some forms of depression, increased appetite and weight gain are common. This is not a weakness of willpower but one of the ways depression shows itself in the body. As mood improves, eating patterns often settle as well; during this process, focusing on regular meals is more helpful than punishing yourself.
Why do my sugar cravings get worse in the evenings?
Evenings are when the tiredness and emotions held back during the day come to the surface. Sweets provide short-term relief. Not skipping meals during the day, planning other small ways of unwinding in the evening and noticing your feelings at these times can help reduce the cravings.
When does loss of appetite in depression become dangerous?
In cases of marked weight loss in a short time, reduced fluid intake as well, dizziness, being too weak to stand, or being unable to eat almost anything for days, a doctor should be seen without delay. These situations can directly affect physical health.
