Body image dissatisfaction and biases on weight as well as body size and shape, cultivated by a stance of privilege, often excluding many individuals, pervade societal norms. Due to the multivariant nature and connectedness of body image concerns, counselors working with clients who present with these issues could struggle with their own biases. How counselors manage this struggle within the therapeutic relationship could be a key factor in treatment effectiveness. Over the last decade, researchers have examined components of weight-based discrimination in connection to counselor countertransference and treatment outcomes. Although these negative attitudes could negatively impact therapeutic outcomes for clients, the prevalence of weight bias among counselors and its impact on therapeutic outcomes is not fully understood. The purpose of this transcendental phenomenological study was be to explore counselors' awareness of their weight bias in their clinical work with clients of various body sizes. A review of the literature indicated the factors that may impact counselors' weight bias, weight-based discrimination, and closely examined sociocultural connections to beauty and body image. Answering the research questions required exploring counselors' perspectives of their implicit weight biases and the influences on the therapeutic alliance and clinical work with clients who present with disordered eating, body image concerns, and eating disorders.
