Here are some examples:
- In "The Rocky Horror Glee Show", Sam clearly exhibits signs of body dysmorphic disorder, thinking he's fat and cursing himself for eating Doritos, yet becomes a stripper somewhere between "New York" and "Hold On to Sixteen".
- Santana's possible bulimia/anorexia/other eating disorder e.g. the excitement over the "Sue Sylvester Master Cleanse" in "Home", Rachel hearing someone throwing up in the bathroom and automatically assuming it's Santana in "New York", Mercedes' comment "like you eat" in "Asian F".
- Quinn's post-pregnancy body has been joked about several times ("Dream On", "Audition", "A Very Glee Christmas" and "Prom Queen")
- Rachel's attempts at bulimia are met with an oral sex joke in "Showmance".
