What Is Orthorexia? When Healthy Eating Becomes an Unhealthy Obsession

It is safe to say that today's world is obsessed with wellness and fitness. In such a scenario, the pursuit of a perfect diet can sometimes feel overwhelming. It may even cross the line from a healthy habit into a mental health disorder. This intense fixation with eating clean is known as orthorexia. It is a condition that can severely affect a person's mental, physical, and social well-being. 

We consulted a mental health expert to understand the hidden warning signs of this disorder and learn how to build a good relationship with food. Let us take a look at what Dr Sharadhi C, Consultant, Psychiatry, Aster CMI Hospital, Bangalore has to say about it.

What is Orthorexia? 

Let us first understand what orthorexia is. Explaining this, Dr Sharadhi says, “Eating healthy is important, but when a person becomes extremely obsessed with eating only foods they consider ‘pure’ or ‘healthy’, it can become harmful instead of helpful. This condition is called orthorexia.” 

The expert further explains, “Although it is not officially recognised as a separate mental health disorder in major diagnostic manuals, mental health experts acknowledge that it can seriously affect a person's emotional wellbeing, physical health, and daily life.”

Shedding light on its symptoms, Dr Sharadhi says, "People with orthorexia may spend hours planning meals, reading food labels, avoiding entire food groups without medical reasons, and feeling anxious or guilty if they eat something they believe is unhealthy. Over time, this rigid thinking can lead to poor nutrition, weight loss, social isolation, stress, and strained relationships. This is because eating becomes a source of fear rather than enjoyment.”

A 2025 study, published in the journal Heliyon, examined how this condition transitions from a simple desire for a healthy lifestyle into a consuming psychological illness. To understand this shift, researchers interviewed people who are deeply committed to healthy diets. They were asked about their daily routines, thoughts, and inner struggles. 

The study discovered that the causes of orthorexia originates from a deep need for control and a strong desire to feel physically and morally pure, especially in a modern food environment perceived as toxic. It notes that while the journey starts with pure intentions to improve overall well-being, it can quickly spiral into intense fear. 

What Causes Obsession with Healthy Eating? 

Now let us understand what are its causes. Dr Sharadhi explains, “Orthorexia often develops gradually and may begin with a genuine desire to improve health, lose weight, manage a medical condition, or follow wellness trends seen on social media. However, the focus slowly shifts from balanced nutrition to strict food rules, making it difficult for the person to enjoy meals or eat spontaneously with family and friends.” 

What happens as a result of this? The expert answers, “They may avoid restaurants, celebrations, and travel because they cannot control what is served, leading to loneliness and emotional distress. Unlike healthy eating, which allows flexibility and balance, orthorexia is driven by fear, perfectionism, and anxiety, making food choices control a person's thoughts and daily routine.”

The above mentioned study mentions some of the key signs of the disorder as follows:

• Obsessively researching nutritional facts.
• Constantly judging the safety of ingredients.
• Strictly categorising foods as either completely ‘good’ or entirely ‘contaminated’.
• Experiencing a heavy moral burden and intense guilt whenever they deviate even slightly from their self-imposed rules. 

The findings conclude that when eating habits are led by rigid control and moral judgment, instead of genuine nourishment, even the ‘cleanest diet’ transforms into a deeply harmful pathology.

Tips to Deal With Orthorexia 

Dr Sharadhi says that recognising orthorexia early is important because timely support can prevent both mental and physical health complications. On this note, the expert shares some tips to deal with the eating disorder:

• Treatment usually involves guidance from a mental health professional, a dietitian, and sometimes a physician to address nutritional deficiencies and unhealthy eating patterns.
• Therapy can help people challenge rigid beliefs about food, reduce anxiety, and rebuild a healthier relationship with eating.
• Family members should encourage support without criticism, as judgement may worsen guilt and stress. 

“The goal of treating orthorexia is not to stop eating healthy foods but to develop a balanced, flexible approach where nutrition supports overall wellbeing without causing fear, isolation, or emotional suffering,” concludes Dr Sharadhi.
