Internalised Weight Bias
Internalised weight bias is what happens when a person absorbs the negative messages society holds about higher body weights and turns them on themselves, producing shame, self-blame and a sense of not deserving help.
Plain English
Patient-Friendly Explanation
There are strong negative messages in most societies about higher body weights, and people who live in larger bodies hear them constantly - in the media, in shops, sometimes in clinics and often in family conversation. Internalised weight bias is what happens when those messages are taken inwards and accepted as true about oneself: a sense of being lazy, unworthy or at fault. It shows up as shame before a consultation, avoiding gyms or pools, eating in secret, or abandoning a plan the moment it slips. Recognising it is part of treatment, not a side issue, because the same shame is what keeps people away from care.

Clinical Definition
Internalised weight bias, also called internalised weight stigma or weight self-stigma, is the acceptance and self-application of negative weight stereotypes. It is measured with the Weight Bias Internalisation Scale (WBIS) and the Weight Self-Stigma Questionnaire (WSSQ). It correlates with binge eating, disordered eating, depressive and anxiety symptoms, lower physical activity, higher avoidance of health care, and poorer retention and outcomes in behavioural weight management programmes, in most studies independently of BMI itself. The proposed mechanisms are experiential avoidance, shame-based coping, and reduced self-efficacy, which in turn undermine the self-monitoring and follow-up that any effective programme depends on. Interventions with randomised support include self-compassion training, acceptance and commitment therapy, cognitive restructuring of weight-related beliefs, and clinician training to remove blaming language from consultations. Weight stigma in the health care environment is a separate but interacting factor: patients who expect judgement delay appointments and screening.
Key Insight
Why It Matters
Asking about shame rather than only about food is often what unlocks engagement, and the way a clinic speaks about weight is itself part of the treatment rather than just bedside manner.
