Eating disorders affect people of all body sizes

When many people hear the word starvation, they picture someone who is visibly and extremely underweight. It is an image reinforced by films, media coverage and even some health messaging about eating disorders.

But the reality is much more complicated.

A person does not have to look emaciated to be experiencing the physical and psychological consequences of inadequate nutrition. Someone can live in a larger body, an average-sized body or a smaller body and still be consistently eating less than their body needs. They may be losing weight rapidly, skipping meals, fasting, following rigid food rules or compensating for eating through excessive exercise or purging behaviours.

From the outside, these behaviours may even be praised.

Someone might hear:

“You look amazing.”

“You've lost so much weight!”

“You're so disciplined.”

“What diet are you doing?”

Yet behind those comments, that person's body may be struggling with insufficient energy. Their thoughts may increasingly revolve around food. They may feel cold, exhausted, anxious or irritable. Concentration may become difficult. Their relationship with food might become progressively more restrictive and frightening.

This is one of the reasons eating disorders can be missed.

At Eat At Ease Counselling, we believe it is important to move away from the idea that you can determine someone's nutritional or psychological wellbeing simply by looking at their body.

Understanding what happens when the body does not receive enough food can also help us understand why eating-disorder recovery involves much more than simply telling someone to “eat normally.”

What do we mean by starvation?

The word starvation can sound dramatic. However, medically, the important issue is whether the body is consistently receiving enough energy to meet its needs.

Our bodies require energy every day simply to keep us alive.

Energy is needed for the heart to beat, the brain to function, the lungs to work, the digestive system to operate, hormones to be produced, body temperature to be regulated and cells and tissues to repair themselves.

On top of those basic requirements, we need energy to move, work, study, exercise, socialise, care for children and carry out everyday life.

When insufficient energy is available over time, the body has to adapt.

One of the most important points to understand is that this can happen at any body size.

A person's appearance does not tell us whether their body is adequately nourished.

This matters enormously in eating-disorder treatment because cultural stereotypes can lead people to believe they are “not sick enough” to deserve help.

Eating disorders don't have a particular look

There remains a powerful stereotype of what someone with an eating disorder is supposed to look like.

Often, that stereotype is someone who is visibly underweight.

As a result, people whose bodies do not fit that image can struggle to recognise their own illness.

They might think:

“I can't have an eating disorder because I'm not thin.”

“Other people are much worse than me.”

“My weight is still considered normal, so I must be fine.”

“Surely I would have to lose more weight before anyone would take this seriously.”

These thoughts can become particularly dangerous when they are reinforced by other people.

A person may be restricting food intensely and experiencing significant physical symptoms, while friends, relatives or even healthcare professionals congratulate them for losing weight.

Instead of concern, they receive praise.

That creates a deeply confusing situation. The body may be signalling distress while the surrounding culture is communicating that the behaviour producing that distress is an achievement.

Eating disorders should therefore never be assessed solely by appearance or a number on a scale.

The person's eating behaviours, thoughts about food and body image, weight history, physical symptoms, psychological wellbeing and overall functioning all matter.

What happens when the body doesn't get enough energy?

The human body is remarkably adaptive.

When food becomes scarce, it does not simply continue operating normally while waiting for more energy to arrive. It begins making adjustments designed to conserve resources.

In simple terms, the body starts prioritising survival.

Processes that are not immediately essential may receive less energy. Metabolism can adapt. Hormonal systems can change. Digestion may slow. Energy levels may fall. Reproductive functioning can be affected. Thinking and concentration can become more difficult.

These adaptations are evidence that the body is trying to protect itself during a period of inadequate energy availability.

Unfortunately, some of these changes can reinforce the eating disorder.

For example, inadequate nutrition can increase preoccupation with food. A person may find themselves constantly thinking about their next meal while simultaneously becoming increasingly frightened of eating it.

They may spend hours looking at recipes, watching food videos or planning what they will eventually allow themselves to eat.

Concentration can deteriorate, making work or study harder.

Mood can change too. Someone who previously felt relatively emotionally stable may become more anxious, irritable, withdrawn or rigid.

Food restriction is therefore not simply something happening to the stomach or to body weight.

The brain is affected by inadequate nutrition too.

That is one reason nutritional rehabilitation can be such an important part of psychological recovery.

Anorexia nervosa is more than low weight

Anorexia nervosa involves persistent restriction of energy intake alongside significant difficulties relating to weight, body image and the fear of gaining weight.

People may experience an intense fear of weight gain or engage in persistent behaviours intended to prevent it.

Their perception of their body may become distorted, and body shape or weight can take on an enormous role in determining how they evaluate themselves.

Anorexia nervosa can involve different patterns of behaviour.

Some people primarily restrict their food intake. Others may experience binge eating and/or engage in compensatory behaviours such as self-induced vomiting or misuse of laxatives or diuretics.

Compulsive or excessive exercise can also occur.

What these presentations share is that food, weight and attempts to control the body can progressively dominate a person's life.

Eating becomes governed less by hunger, enjoyment, preference and connection and increasingly by rules.

There may be rules about what foods are “allowed.”

Rules about when eating is permitted.

Rules about quantities.

Rules about earning food through exercise.

Rules about compensating after eating.

Rules about what the scale is permitted to say.

And as these rules multiply, a person's life can become smaller.

What is atypical anorexia nervosa?

One particularly important diagnosis for challenging stereotypes about eating disorders is atypical anorexia nervosa.

A person with atypical anorexia may experience the restriction, fear of weight gain, body-image disturbance and other psychological and behavioural features associated with anorexia nervosa without being classified as significantly underweight.

That distinction can unfortunately cause people to misunderstand the seriousness of the condition.

The word “atypical” may sound as though the disorder is unusual, mild or somehow less legitimate.

It isn't.

Someone can experience substantial nutritional deprivation and serious psychological distress while remaining in a body that other people perceive as “normal” or “larger.”

They may also have lost a significant amount of weight.

This is why looking only at someone's current weight can conceal important information.

Imagine two people experiencing severe restriction.

One began in a smaller body and became visibly underweight. People around them may quickly become concerned.

Another began in a larger body and lost a substantial amount of weight but remains above the conventional threshold associated with anorexia nervosa.

Their behaviours and distress may be very similar.

Yet the second person may be congratulated.

The difference in how those two people are treated tells us something important about weight stigma, not necessarily about how much they are suffering.

“But I'm not underweight”

This sentence is heard far too often in conversations about eating disorders.

Sometimes it means:

“I'm afraid nobody will believe me.”

Sometimes:

“I don't think I deserve treatment.”

And sometimes:

“Part of me thinks I need to become thinner before I'm allowed to recover.”

That last belief can be particularly powerful.

Eating disorders frequently create moving goalposts. There is always another reason to delay recovery: another kilogram, another clothing size, another food to eliminate or another rule to follow.

Waiting until someone appears stereotypically ill before taking an eating disorder seriously gives the illness more time to become entrenched.

You do not need to reach a particular weight before your relationship with food deserves attention.

If food restriction is controlling your life, that matters.

If you're frightened of gaining weight, that matters.

If eating creates intense guilt or anxiety, that matters.

If you're compensating for food through exercise, fasting or purging, that matters.

And if thoughts about calories, weight and food are taking over your day, that matters too.

Why rapid or significant weight loss matters

Weight is only one piece of a much bigger clinical picture, but changes in weight can provide useful information.

A person's body may experience substantial stress after losing a significant proportion of its previous weight, even when their current weight does not fall into an “underweight” category.

Clinicians may therefore consider someone's weight history rather than focusing exclusively on today's number.

Not everyone with an eating disorder loses substantial amount of weight. Some people's weight may remain relatively stable despite severe restriction, chaotic eating patterns, compensatory behaviours or considerable psychological distress.

This is why comprehensive assessment matters.

A person is more than their BMI, weight or weight-loss percentage.

Weight stigma can make eating disorders harder to recognise

Weight stigma is not merely about hurtful comments.

It can affect whether harmful behaviours are recognised as harmful.

Consider two people engaging in the same restrictive behaviour.

If a thin person says, “I've barely eaten all week,” people may express concern.

If a person in a larger body describes similar restriction, they may be praised for their “willpower.”

The behaviour hasn't become safer because the person's body is larger.

Yet our cultural assumptions about weight can dramatically change our response.

People may consequently learn to distrust their bodies.

Hunger becomes something to conquer.

Eating becomes a sign of weakness.

Weight loss becomes automatically associated with health, regardless of how it was achieved.

And weight gain becomes something to fear, regardless of why the body may need it.

For someone vulnerable to an eating disorder, these messages can provide fertile ground for increasingly restrictive behaviour.

Dieting, fasting and “clean eating”

Not every person who diets develops an eating disorder, and eating disorders cannot be reduced to one simple cause.

They are complex conditions influenced by interacting biological, psychological and social factors.

However, restrictive eating can sometimes begin in socially acceptable ways.

Someone decides to “get healthy.”

They remove a few foods.

Then a few more.

They start counting calories.

They begin skipping breakfast.

Perhaps they start fasting for increasingly long periods.

Exercise changes from something enjoyable to something they feel compelled to do.

Eating at restaurants becomes stressful because the calorie content is unknown.

Social events are avoided because food might be involved.

Foods become divided into categories of “good” and “bad,” “clean” and “dirty,” or “safe” and “unsafe.”

What began as an attempt to improve health can gradually become a life organised around avoiding food and controlling the body.

The language surrounding these behaviours can make them difficult to recognise.

Restriction may be described as “discipline.”

Compulsive exercise may be called “dedication.”

Food anxiety may be disguised as “clean eating.”

And significant weight loss may automatically be celebrated as “getting healthier.”

But health cannot be determined from weight loss alone.

How that weight loss occurred matters.

Physical wellbeing matters.

Mental wellbeing matters.

The person's relationship with food matters.

And quality of life matters.

ARFID and inadequate nutrition

Not all restrictive eating disorders involve a desire to lose weight.

Avoidant/Restrictive Food Intake Disorder (ARFID) is an important example.

People with ARFID may struggle to consume enough food without having the body-image concerns or fear of weight gain typically associated with anorexia nervosa.

Restriction may instead be connected with sensory characteristics of food, very limited interest in eating or fear of consequences associated with eating, such as choking or vomiting.

The reasons for restriction are therefore different.

But the body still needs energy.

If someone consistently cannot consume enough nutrition, physical consequences of inadequate energy intake can occur regardless of whether body image played any role in creating the restriction.

This distinction is important because someone does not need to dislike their body or want to become thinner to have a serious eating disorder.

Why “just eat” doesn't work

To someone who has never experienced an eating disorder, the solution can appear obvious.

If someone isn't eating enough, why can't they simply eat more?

Because eating disorders are not simply a lack of knowledge about nutrition.

A person may intellectually understand that their body needs food while experiencing intense anxiety when they actually try to eat it.

They might know that carbohydrates are necessary while feeling terrified of bread.

They may know that one meal cannot dramatically change their body while experiencing overwhelming guilt after eating it.

They may desperately want freedom from their eating disorder while another part of them remains frightened of what recovery could mean.

This apparent contradiction is not unusual.

Eating-disorder recovery often involves learning to tolerate anxiety and uncertainty while gradually challenging behaviours and beliefs that have become deeply established.

Food is essential, but psychological support can also be essential.

Malnutrition can affect thinking

There is another reason recovery can become difficult.

The brain itself requires adequate energy.

When someone is undernourished, their capacity for flexible thinking, emotional regulation and concentration can be affected.

The person may become increasingly rigid about routines and food rules.

Decision-making may become exhausting.

Obsessive thinking about food can intensify.

That creates something of a vicious circle.

Restriction affects the brain.

The undernourished brain may then become increasingly preoccupied, anxious and rigid.

Those changes can make challenging the restriction even more difficult.

This helps explain why eating-disorder treatment often addresses nutritional restoration and psychological recovery together rather than treating them as completely separate issues.

Recovery isn't something you have to earn

One of the cruellest messages an eating disorder can create is the belief that a person must become “sick enough” before they deserve help.

There is no useful finish line at the end of that thought.

Whatever point you reach, the eating disorder can move the standard.

If you've lost weight, it can tell you to lose more.

If you're restricting, it can tell you that somebody else restricts more.

If you're struggling physically, it can tell you you're exaggerating.

If you're struggling psychologically, it can tell you it doesn't count because nobody can see it.

Recovery does not have to begin at the lowest weight someone has ever reached.

It does not require hospitalisation.

It does not require other people to notice.

And it does not require fitting the stereotypical image of an eating disorder.

Early support can prevent months or years of additional suffering.

Looking at the whole person

Good eating-disorder care needs to see more than a number.

Weight can sometimes provide clinically relevant information, but it cannot describe someone's complete physical or psychological condition.

A fuller picture asks different questions.

How much is this person eating?

Has their eating changed significantly?

Are they restricting entire food groups?

How frightened are they of eating or gaining weight?

Are they experiencing binge eating or compensatory behaviours?

Has exercise become compulsive?

How much of their day is consumed by thoughts about food and their body?

Are they withdrawing socially?

What physical symptoms are occurring?

How is their mood?

What is happening in their relationships?

What has happened to their quality of life?

Most importantly, what is this person experiencing?

Those questions help move us from judging a body to understanding a human being.

Creating a different relationship with food

Recovery from restrictive eating is not simply about increasing calories until a target is reached.

Ultimately, it is about developing a relationship with food in which eating no longer needs to be dominated by fear, punishment or rigid rules.

That can mean learning to recognise hunger again.

Allowing previously forbidden foods back into life.

Eating even when the eating disorder says you shouldn't.

Reducing compensatory behaviours.

Challenging beliefs connecting thinness with worth.

Learning that rest does not have to be earned.

Finding ways to manage difficult emotions that don't involve controlling food.

And gradually discovering that a person's identity can be much bigger than their body.

These changes rarely happen all at once.

Recovery often involves repetition. Something that feels terrifying the first time may still feel difficult the fifth time but become more manageable by the twentieth.

The aim isn't necessarily to wait until fear disappears before doing something.

Recovery means learning that fear can be present and you can still choose differently.

How counselling can help

Eating disorders often have a way of turning private thoughts into unquestioned truths.

“I ate too much.”

“I need to compensate.”

“I'll be happier when I'm thinner.”

“People will judge me if I gain weight.”

“I don't deserve to eat because I haven't exercised.”

“I'm not ill enough for help.”

When these thoughts circulate internally for long enough, they can begin to feel like facts.

Counselling offers a space to become curious about them.

Where did these beliefs come from?

What keeps them going?

What happens emotionally when you challenge them?

What does controlling food provide for you?

What does it cost you?

What would life look like if food occupied less mental space?

Eating disorders are complex, and appropriate care can involve collaboration between professionals such as a GP or other medical practitioner, therapist and dietitian depending on the person's individual circumstances and level of medical risk.

Counselling can support the psychological part of that process: understanding patterns, developing alternative ways of coping, challenging eating-disorder beliefs and reconnecting with a life that is not organised around food and weight.

You can't tell who needs help by looking at them

Perhaps the most important message is this:

There is no single eating-disorder body.

Someone can be underweight and struggling.

Someone can be at an average weight and struggling.

Someone can live in a larger body and be struggling.

Someone can lose weight and be struggling.

Someone's weight can remain relatively stable and they can still be struggling.

Appearance cannot tell us how frightened someone feels at dinner.

It cannot show how many hours they spend thinking about calories.

It cannot reveal whether exercise has become compulsive.

It cannot tell us whether they avoid seeing friends because eating might be involved.

And it cannot tell us whether their body is receiving everything it needs.

Moving beyond stereotypes allows us to respond to eating disorders with greater compassion and, importantly, to recognise difficulties earlier.

A message from Eat At Ease Counselling

If you are reading this while wondering whether your difficulties are “bad enough” to deserve support, consider asking a different question.

Instead of:

“Am I sick enough?”

you might ask:

“Is my relationship with food, exercise or my body making my life harder?”

Perhaps eating causes significant anxiety.

Perhaps food rules are becoming increasingly rigid.

Perhaps you've lost a substantial amount of weight and everyone congratulates you, even though you know what you are doing to maintain that loss is hurting you.

Perhaps you spend far more time thinking about food than you want to.

Perhaps you are exhausted from fighting your body.

Or perhaps you cannot quite explain what is wrong - you simply know that eating no longer feels easy.

Those experiences are worth talking about.

At Eat At Ease Counselling, our focus is on understanding what is happening for the individual: their thoughts, behaviours, fears, experiences and relationship with food and their body.

Eating disorders and disordered eating can exist across the weight spectrum.

You do not need to wait until things become worse before seeking support.

You do not need to look a particular way.

And you do not have to prove the seriousness of your struggle by becoming physically smaller.

The possibility at the heart of recovery is much bigger than eating differently.

It is the possibility of having more mental space for relationships, interests, work, creativity, rest and ordinary everyday experiences. It is being able to sit down for a meal without an internal calculation determining whether you deserve it. It is allowing your body to have needs without treating those needs as failures.

It is moving towards a life in which food can simply be food again.
