Healthy Eating and Eating Disorders Overview
Healthy Eating
- Definition: According to the National Eating Disorders Association (NEDA), "normalized, non-disordered eating" refers to a diet that includes a variety of foods, allowing individuals to mindfully respond to hunger cues while also being able to stop eating when they feel full.
- Characteristics of Healthy Eating:
- Individuals can choose foods they enjoy and consume what they need and desire.
- Eating is free from anxiety or guilt.
- There is a thoughtful consideration of nutritious choices without obsession over caloric content or extreme restrictions.
Eating Disorder Facts
- Mortality Rates:
- Eating disorders have one of the highest mortality rates among mental health disorders (Anorexia Nervosa and Associated Disorders, 2020).
- They claim 10% of lives affected by these syndromes (Magnolia Creek, 2019).
- At least one person dies every 52 minutes due to an eating disorder (ANAD, 2020).
- Approximately 30 million people in the U.S. have struggled with an eating disorder at some point in their lives (NEDA, 2021b).
Eating Disorder Indicators
- Behavioral Changes:
- Secrecy and rituals surrounding food/eating.
- Obsessive Behaviors:
- Focus on calorie counting and fixation on food, weight, body shape, and size.
- Functional Changes:
- Impacts on social, work, and school life.
- Lowered self-esteem and potential physical illnesses.
Eating Disorder Warning Signs
- Physical Changes:
- Unexplained weight fluctuations (loss/gain).
- Behavioral Signs:
- Lying about food consumption.
- Engaging in secret eating or bingeing.
- Excessive exercise routines.
- Preoccupation with weight and body image.
- Intense fear of fat.
Eating Disorders: Major Classifications
- Anorexia Nervosa (AN):
- Characterized by self-induced starvation.
- Bulimia Nervosa (BN):
- Involves binge eating followed by purging behaviors.
- Binge-Eating Disorder (BED):
- Involves repeated rapid consumption of large amounts of food unrelated to hunger (APA, 2013).
Other Eating Disorders
- Avoidant Restrictive Food Intake Disorder:
- Inflexible eating habits, strong sensory aversions or fears of certain foods.
- Orthorexia:
- An obsession with eating "clean" foods.
- Diabulimia:
- Diabetics who stop taking insulin to lose weight.

Risk Factors
- Mental Health Conditions:
- Anxiety, depression, and substance misuse can increase risk.
- Personality Disorders:
- Includes obsessive-compulsive, avoidant, and borderline personality disorders.
Continued Risk Factors
- Biological/Genetic Influences:
- Family history of eating disorders, although no specific gene has been isolated yet.
- Socioeconomic Stresses:
- Influenced by culture, occupation, family dynamics, and potential abuse (ANAD, 2021).
Serotonin Dysregulation
- Research Findings:
- Clinical studies suggest that alterations in the serotonin system can impact feeding behaviors.
- Family history of mood or anxiety disorders may relate to this.
Contributing Biological and Genetic Factors
- Familial Patterns:
- Eating disorders are more common among family members than in the general population.

Complications Arising from Eating Disorders
- Potential Health Issues:
- Diabetes (e.g., ketoacidosis), electrolyte disruptions, osteoporosis (leading to fractures and dental issues).
- Risk of kidney failure, cardiac dysfunction, neuroendocrine problems (thyroid function, menstrual cessation, brain atrophy), as well as skin complications.
Anorexia Nervosa – DSM-5 Criteria
- Energy Intake Restriction:
- Significant reduction of energy intake relative to requirements, resulting in significantly low body weight based on age, sex, developmental stage, and physical health.
- Fear of Weight Gain:
- Intense fear of gaining weight or behaviors that inhibit weight gain even underweight.

Interprofessional Team Approach
- Roles:
- Provider: Prescribes medication and treatments; manages medical complications.
- Nurse: Provides direct care to client, monitors eating patterns, weight, and health status.
- Dietitian: Recommends nutritional intake; collaborates on diet plans.
- Therapist: Conducts counseling sessions addressing emotional and psychological issues.
- Social Worker: Facilitates discharge planning and coordinates case management.

Analyzing Cues/Prioritizing
- Criteria for Analysis:
- Medical Stability: Evaluate physiological functioning.
- Psychosocial Aspect: Assess mood and affect.
- Safety Considerations: Ensure a safe environment for care.
- Educational Needs: Discuss treatment/therapy, medications, nutrition, and resources.
Generating Solutions
- Decisions:
- Determine inpatient or outpatient care based on acuity of condition.
- Address physiological stability needs.
- Engage in nutritional engineering for weight restoration/maintenance.
- Address psychosocial needs related to body image and self-esteem.
Take Action – Nutritional Re-engineering
- Care Strategies:
- Placement in specialized units may occur; dietitian involvement is essential.
- Daily caloric intake may start low (approximately 1800 calories).
- Close monitoring to prevent refeeding syndrome, a condition characterized by fluid/electrolyte shifts and cardiovascular decompensation.
- Regular monitoring of vital signs, weight, and relevant lab tests.
Take Action – Pharmacotherapy
- Medications:
- Vitamins and minerals for deficiencies.
- GI medications such as bulk laxatives and simethicone for discomfort.
- Psychedelic medications (e.g., antidepressants, mood stabilizers, anxiolytics).
- FDA Approved Medications:
- Fluoxetine for bulimia.
- Olanzapine for anorexia.
- Lisdexamfetamine dimesylate for BED.
Take Action – Meal Monitoring
- Procedures:
- Meals must occur within a designated timeframe.
- All food on tray should be consumed ( "Food is medicine").
- Supplements may be included in dietary plans.
- Strict calorie counting to ensure nutritional needs are met.
- Vigilance for any food hiding or smearing behaviors.
Take Action – Bathroom Monitoring & Weighing Protocols
- Post-meal Procedures:
- Implement protocols to wait one hour after meals before bathroom breaks to deter purging.
- Daily weights should occur under controlled conditions (morning after voiding, before breakfast).
- Quality control with the use of hospital gowns during weighing.
Take Action – Psychosocial Interventions
- Therapeutic Approaches:
- Acceptance Commitment Therapy: Assists clients in aligning behavior with personal values.
