Policy makers developing obesity policies should assess and reflect on their own attitudes and beliefs related to obesity. Public health policy makers should avoid using stigmatizing language and images. It is well established that shaming does not change behaviours. In fact, shaming can increase the likelihood of individuals pursuing unhealthy behaviours and has no place in an evidence-based approach to obesity management. Avoid making assumptions in population health policies that healthy behaviours will or should result in weight change. Weight is not a behaviour and should not be a target for behaviour change. Avoid evaluating healthy eating and physical activity policies, programs and campaigns in terms of population level weight or BMI outcomes. Instead, emphasize health and quality of life for people of all sizes. Because weight bias contributes to health and social inequalities, advocate for and support people living with obesity. This includes supporting policy action to prevent weight bias and weight-based discrimination. Policy makers should know that most people living with obesity have experienced weight bias or some form of weight-based discrimination. Public health policy makers should consider weight bias and obesity stigma as added burdens on population health outcomes and develop interventions to address them. To avoid compounding the problem, we encourage policy makers to do no harm, and to develop people-centered policies that move beyond personal responsibility, recognize the complexity of obesity, and promote health, dignity and respect, regardless of body weight or shape. Health care providers should ensure their clinical environment is accessible, safe and respectful to all patients regardless of their weight or size. Make efforts to improve health and quality of life rather than solely focusing on obesity management. Ask permission before weighing someone, and never weigh people in front of others; instead, place weighing scales in private areas. Health care providers should consider how their office’s physical space accommodates people of all sizes and ensure they have properly sized equipment (e.g., blood pressure cuffs, gowns, chairs, beds) ready in clinical rooms prior to patients arriving. Because weight bias impacts morbidity and mortality, advocate for and support people living with obesity. This includes action to create supportive healthcare environments and policies for people of all sizes.
