The Association for Size Diversity and Health (ASDAH) is an international professional organization started in 2003. It is an all-volunteer, not-for-profit organization whose diverse membership is committed to education, research, and the provision of services which enhance health and well-being, and which are free from weight-based assumptions and weight discrimination. ASDAH promotes the Health At Every Size (HAES) approach to health. HAES advocates work to promote size acceptance, end weight stigma, and lessen the cultural obsession with weight loss and thinness.
