Compared to straight men, gay men are more likely to diet and binge eat and they may even be at greater risk for eating disorders than straight women. One contributing factor is that the gay subculture tends to emphasize the idealized hyper-masculine male physique. The pursuit of this ideal can lead to excessive exercise and the use of substances such as anabolic steroids and certain supplements that can adversely affect health. 
Adolescents and young adults presenting with an eating disorder may have an underlying conflict related to sexual orientation. 
Healthcare providers should ask their LGBT clients about:
history of dieting
use of diet products and supplements
and whether they feel pressures within the LGBT community to conform to certain notions of body image.
