Health at Every Size (HAES) concept promotes health irrespective of weight. This study aimed to determine the correlates of HAES alignment in registered dietitians (RDs). Of the 246 RDs, 34.1%, 34.6%, 13%, and 18.3% were aligned, somewhat aligned, not aligned with HAES, and unaware of HAES, respectively. Weight blame was lower in RDs aligned with HAES than among others (P = .001). Alignment with HAES was not associated with body mass index, prior weight bias training, practicing weight management, or implicit weight bias (P > .05). Understanding the correlates of HAES in RDs is important for the care of individuals with higher weight.
