Two small studies of adults with obesity linked internalized weight stigma to dysregulated cortisol (Jung et al., 2020; Nicolau et al., 2023), with one study also finding an association with greater self-reported chronic stress (Jung et al., 2020); still, one of these studies found no association with other measures of inflammation (e.g., C-reactive protein; CRP; Nicolau et al., 2023). This evidence concerns the gene CRP and obesity due to melanocortin 4 receptor deficiency.
