What is Health At Every Size® (HAES®)?
Health at Every Size® (HAES®) is a framework that helps people step out of the pressure to change their bodies and into a more compassionate, realistic approach to well-being. This framework was created by the Association for Size Diversity and Health (ASDAH). For so many of our clients, it feels like the first time health has been talked about in a way that does not create shame. Instead of tying health to a specific number or size, HAES® focuses on access, respect, and the many factors that shape how we care for ourselves day to day. There is also a lot of confusion about HAES®, including what it actually means in practice. So let’s clear it up.
What is the Core Idea Behind Health at Every Size®?
Health at Every Size® is a weight-inclusive framework that supports people in pursuing well-being without tying it to body size. At its core, HAES® recognizes that:
Bodies naturally come in diverse shapes and sizes
Weight is not a behavior and cannot be reliably controlled
Health is influenced by genetics, trauma, access to care, discrimination, environment, and social conditions
Everyone deserves respectful, compassionate healthcare, regardless of body size
HAES® originated from decades of research and advocacy within the weight science, public health, and eating disorder fields. Many of the ideas in HAES® are not new. They reflect what the evidence has shown again and again: weight is not a reliable indicator of health and weight-focused interventions are often ineffective or harmful. HAES® was created to offer a more ethical, evidence-aligned approach to care, especially for people harmed by weight stigma.
The Five HAES® Principles
ASDAH outlines five core HAES principles. Below they are explained in practical, real-world language.
1. Weight Inclusivity
All people deserve care and respect, regardless of body size. This means moving away from assumptions based on weight and focusing on the full picture of a person’s health.
2. Health Enhancement
Health is supported through access to safe, affirming healthcare, including mental health care, trauma-informed care, and environments that reduce harm.
3. Eating for Well-Being
This principle supports flexible, nourishing eating that honors hunger, fullness, satisfaction, culture, and pleasure. It does not prescribe a single way of eating for everyone.
4. Respectful Care
This principle acknowledges how weight stigma, racism, ableism, homophobia, transphobia, and other forms of oppression impact health. It encourages providers to challenge these barriers.
5. Life-Enhancing Movement
Movement should feel supportive, accessible, and enjoyable. It should not be tied to earning food, burning calories, or changing body size.
What Health at Every Size® Is Not
Because HAES® often gets talked about online without much context, there are a lot of misunderstandings about what it actually stands for. Clearing these up helps people see the framework for what it truly is: a respectful, evidence-aligned approach to care. Here is what HAES® is not:
HAES® is not saying everyone is healthy at every size
This is one of the most common misconceptions. HAES® does not claim that size determines health. Instead, it recognizes that people of all sizes can work toward well-being and deserve access to supportive care.
HAES® is not anti-health or anti-medical care
HAES® does not ignore medical conditions or health concerns. It encourages providers to address health with nuance and without assumptions based on body size.
HAES® is not “letting people eat whatever they want”
HAES® supports a flexible, nourishing, compassionate approach to food. It does not promote chaotic eating or the absence of structure. Instead, it focuses on reconnecting with internal cues and individual needs without external rules or shame.
HAES® is not a diet or weight-loss alternative
It is not another plan or program. HAES® shifts the conversation entirely, moving away from weight manipulation and toward sustainable behavior change, nervous system support, trauma-informed care, and internal cues.
HAES® is not anti-weight loss
People may lose, gain, or maintain weight throughout their lives for many reasons. HAES® does not judge those changes or try to control them. It simply does not prescribe weight loss as a treatment goal.
HAES® is not ignoring the impact of social conditions
HAES® openly acknowledges that health is shaped by access, discrimination, trauma, safety, privilege, and environment. It does not pretend health is only about personal choice or individual responsibility.
HAES® is not one-size-fits-all
HAES® leaves room for nuance, identity, culture, disability, neurodivergence, chronic illness, and real-life complexity. It adapts to the person rather than asking the person to adapt to a rigid system.
Why Many Providers Are Moving Toward a HAES® Approach
More providers are adopting HAES®-informed care because:
Weight-centric care often leads to avoidance of medical care, delayed treatment, or mistrust.
Evidence shows that behavior-based and compassion-centered approaches support long-term health more effectively than weight-focused ones.
HAES® supports health equity by addressing barriers that shape people’s lived experiences.
Providers are recognizing that health is complex and cannot be measured by a single number.
What HAES®-Aligned Care Looks Like in Practice
A HAES-aligned provider might help you:
Build consistent eating patterns without dieting
Navigate hunger and fullness cues
Explore your relationship with movement
Understand how stress, sleep, trauma, and environment affect your body
Work through internalized weight stigma
Create a more respectful, trusting relationship with healthcare
The goal is to support your health in a way that feels sustainable and compassionate. Health at Every Size® is not a trend or a quick fix. It is a framework rooted in evidence, ethics, and respect. If you have ever felt dismissed, judged, or misunderstood in healthcare spaces, HAES® may offer a more supportive path forward. If you are curious about how HAES® could support your relationship with food and your body, we’re here to help you explore this in a shame-free, collaborative way.
