Key points
- Weight stigma means judging people for their size. It covers negative attitudes, stereotypes and unfair treatment because of body weight.
- It is very common. In a survey of almost 14,000 adults in a weight programme in six countries, 56 to 61 % said they had experienced it.
- It often comes from people close by. Family members, classmates, doctors and colleagues were the most frequent sources.
- It harms health. An analysis of 105 studies linked weight stigma to poorer mental health, and it can keep people away from care.
- Shame does not help people lose weight. Research shows stigma adds stress and can lead to more weight gain.
- Everyone can help stop it. Use person-first language, speak up against jokes and offer support without judgement.
What is weight stigma?
Weight stigma is the negative way people are seen and treated because of their body size. It ranges from jokes and remarks to unequal chances at work and poorer care.
Weight bias is the attitude behind it: the belief that people in larger bodies are lazy or lack willpower. It can be open or unconscious. See the glossary for both terms.
Where does weight stigma happen, and what can you do?
Weight stigma happens almost everywhere in daily life. The table shows the most common places and first steps you can take.
| Where | What it can look like | What you can do | Read more |
|---|---|---|---|
| Family and friends | Remarks about your body or plate, diet advice nobody asked for | Say how the remarks affect you; ask for help with shared activities instead | Supporting a loved one |
| School | Teasing, bullying, being left out of games or sport | Tell a teacher or school counsellor; schools can act on bullying | Obesity in children |
| Healthcare | Every complaint blamed on weight, chairs or cuffs that do not fit | Ask for the same tests anyone would get; bring someone you trust | Stigma in healthcare |
| Work | Fewer job offers or promotions, jokes in the team | Keep notes, talk to HR or a union, check local law | Weight and work |
| Media and online | Photos without heads, jokes, stories that blame | Report harmful posts; follow sources that use respectful words | Person-first language |
| Your own thoughts | Believing the negative messages and blaming yourself | Talk to someone you trust or a psychologist | Psychological support |
How common is weight stigma?
A survey of almost 14,000 adults in a weight-management programme in Australia, Canada, France, Germany, the UK and the US found that more than half had faced weight stigma. It was most frequent, and most upsetting, in childhood and the teenage years.
Among those affected, most had faced it from family members (76 to 88 %) and classmates (72 to 81 %). Doctors (63 to 74 %) and co-workers (54 to 62 %) followed.
How does weight stigma harm health?
An analysis of 105 studies with about 59,000 people found a clear link between weight stigma and poorer mental health. The link was stronger at higher body weight.
Stigma can also turn inward. In the six-country survey, people who blamed themselves more avoided care, went to fewer check-ups and felt less respected by doctors. Read more about weight stigma in healthcare.
Why does shaming people not work?
Some people think shame will push others to lose weight. The evidence shows the opposite: stigma is linked to stress, binge eating, avoiding care and further weight gain.
Researchers therefore advise changing the attitudes of those who stigmatise, not the people who are targeted. An international expert consensus calls on healthcare, media and governments to end weight stigma.
Which words should you use?
Words matter. Say a person living with obesity rather than an obese person. The condition is something a person has, not who they are.
Avoid words that blame, such as lazy, and images that show people without their head or in unflattering poses.
How can you support someone and speak up?
- Do not comment on someone’s body or food unless they ask.
- Ask how you can help, instead of assuming.
- Join in with activities you can do together, without making weight the topic.
- Speak up when you hear jokes or blame.
- Encourage professional care, and offer to come along to an appointment.
- Remember that health is about much more than a number on the scale.

What can healthcare professionals do?
Ask permission before discussing weight. Use neutral words such as weight and body mass index, and look for other causes of symptoms instead of blaming everything on weight.
Make sure your practice has suitable chairs, blood pressure cuffs and scales. Experts recommend training on weight bias for all healthcare teams.
Where can you get support after weight stigma?
Talking helps: to someone you trust, your doctor or a psychologist. If you want to work on your health in your own way, sign up for free: we offer eating plans, workout videos and a free video meeting (in English), without judgement.
Frequently asked questions
What is person-first language?
Person-first language puts the person before the condition, for example 'a person living with obesity' instead of 'an obese person'. It reduces stigma and is recommended by international obesity organisations.
Does weight stigma motivate people to lose weight?
No. Research shows the opposite: weight stigma is linked to stress, binge eating, avoiding healthcare and weight gain.
How do I talk to a loved one about their weight?
Only if they want to. Ask open questions, listen without judgement, focus on health and wellbeing rather than appearance, and offer practical support such as going to an appointment together.
Is weight stigma common?
Yes. In a survey of almost 14,000 adults in six Western countries, between 56 and 61 % said they had experienced weight stigma. People with a higher BMI reported it more often, and most first met it in childhood or as teenagers.
Who is most often the source of weight stigma?
In a large six-country study, family members were named most often, followed by classmates, doctors, co-workers and friends. That is why change has to start close to home, as well as in schools, healthcare and the media.
What is internalised weight bias?
It means a person starts to believe negative messages about weight and blames themselves. Research links it to avoiding healthcare, fewer check-ups and feeling less respected by doctors. Talking to a psychologist or someone you trust can help.
