Understanding Eating Disorders: Signs, Causes, and How Psychotherapy Can Help

Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, and ARFID

Eating disorders are complex mental health conditions that affect people of all ages, genders, and backgrounds. They are not simply about food; they involve emotional pain, perfectionism, anxiety, shame, and often a deep struggle with self-worth. At Atlas Therapy, we specialize in supporting individuals living with

Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, and Avoidant/Restrictive Food Intake Disorder (ARFID). With

specialized, compassionate care, recovery is possible.

Let’s break down the key types of eating disorders, their signs and impacts, and how evidence-based therapy can support long-term healing:

What Are Eating Disorders?

Eating disorders are diagnosable mental health conditions characterized by persistent disruptions in eating habits, thoughts about food and body image, and emotional distress. They can lead to significant physical and psychological harm if left untreated. Contrary to stigma, eating disorders are not a choice, and recovery requires skilled therapeutic support.

Many individuals experience overlapping symptoms or move between diagnoses throughout their lives. Early intervention significantly improves outcomes, but therapy can be effective at any stage of recovery.

Anorexia Nervosa – Restricting Type (AN-R)

Anorexia Nervosa (Restricting Type) involves severe limitations on food intake without regular bingeing or purging behaviours. People with AN-R often struggle with an intense fear of gaining weight and a distorted body image, believing they are larger than they are.

Common Signs of AN-R:

Extreme restriction of calories or certain food groups

Rigid food rules and obsessive thoughts about eating

Significant weight loss or inability to maintain an appropriate weight

Excessive exercise

Perfectionism and high self-criticism

Feeling “in control” through food restriction

How Therapy Helps

Therapy focuses on rebuilding a healthy relationship with food, challenging distorted beliefs about weight and body image, and addressing the underlying emotional factors such as anxiety, trauma, or a need for control that fuel restrictive behaviours.

Anorexia Nervosa – Binge-eating/Purging Type (AN-BP)

The binge-eating/purging type of Anorexia Nervosa involves periods of restrictive eating followed by episodes of bingeing or purging (vomiting, laxatives, or compulsive exercise). Weight may still be dangerously low despite these cycles.

Common Signs of AN-BP:

Restrictive eating with episodes of bingeing or purging

Intense guilt or shame after eating

Highly distorted body image

Difficulty regulating emotions

Secretive behaviour around food

How Therapy Helps

Therapy supports emotional regulation, decreases binge-purge cycles, and helps restore physical and psychological balance. The therapeutic process often integrates grounding skills, compassion-focused approaches, and structured meal support.

Bulimia Nervosa (BN)

Bulimia Nervosa is characterized by cycles of binge eating followed by compensatory behaviours such as vomiting, laxative use, fasting, or excessive exercise. Unlike anorexia, individuals with bulimia often maintain a weight within or above the typical range, which means the disorder can be harder to detect.

Common Signs of Bulimia Nervosa:

Repeated episodes of eating large quantities of food

Feeling out of control during binges

Purging or extreme compensatory behaviours

Swelling of cheeks/jaw (from vomiting)

Frequent trips to the bathroom after meals

Intense shame and secrecy

How Therapy Helps

Therapy explores the emotional triggers behind bingeing, helps reduce compensatory behaviours, and strengthens self-worth. Cognitive Behavioural Therapy (CBT-E) is particularly effective, focusing on patterns of restriction that often drive binge episodes.

Binge Eating Disorder (BED)

Binge Eating Disorder is the most common eating disorder, involving recurrent episodes of eating unusually large amounts of food accompanied by a sense of loss of control – but without purging behaviours. Many individuals experience distress, shame, or emotional numbness during binges.

Common Signs of BED:

Eating large quantities of food, often quickly

Eating past fullness or when not hungry

Emotional eating triggered by stress or difficult feelings

Feeling ashamed, guilty, or disgusted afterward

Eating alone or in secret

How Therapy Helps

Treatment focuses on emotional regulation, reducing shame, building mindful eating habits, and healing underlying triggers such as trauma, loneliness, stress, or chronic dieting patterns. Therapy also helps individuals cultivate self-compassion and dismantle harmful beliefs about food and body image.

Avoidant/Restrictive Food Intake Disorder (ARFID)

ARFID is not driven by body image concerns. Instead, it involves extreme restriction or avoidance of certain foods due to sensory sensitivity, fear of choking or vomiting, or a general lack of interest in eating. ARFID can occur in children, teens, or adults and often goes unrecognized.

Common Signs of ARFID:

Very limited variety of foods consumed

Avoidance due to texture, smell, colour, or past negative experiences

Strong sensory sensitivity around food

Significant weight loss or nutritional deficiencies

Anxiety around mealtime

How Therapy Helps

Therapy may involve gradual exposure to avoided foods, emotion regulation strategies, sensory integration support, and addressing the fears that make eating feel unsafe or overwhelming.

Why Psychotherapy Is Essential in Eating Disorder Recovery

Eating disorders are not solely about behaviour – they are deeply connected to emotional experiences, trauma, stress, identity, family dynamics, and personal coping patterns. Psychotherapy helps individuals understand the root causes of their symptoms and build long-lasting, sustainable change.

Evidence-Based Therapies We Use:

CBT (Cognitive Behavioural Therapy)

DBT (Dialectical Behaviour Therapy)

ACT (Acceptance and Commitment Therapy)

Trauma-informed therapy

Emotion-Focused and Compassion-Focused approaches

Family-Based Support (when helpful)

Our approach is weight-inclusive, shame-free, and client-centred. We honour each person’s unique relationship with food and body image while providing structure and clinical expertise to guide recovery.

Hope and Healing Are Possible

Eating disorders thrive in secrecy, shame, and isolation. But recovery thrives in connection, support, and compassion. Whether you’re struggling with restriction, bingeing, purging, fear of certain foods, or emotional overwhelm around eating, you are not alone and help is available.
