This Open Access article looks at the reality of anorexia in men, at least in Finland. There is doubtless some similarity in patterns for the rest of Europe and the US. This is a twin study, so it's going to have some interesting outcomes regarding the genetic links to this disorder.
Bottom line is that anorexia is more common in men than previously believed, and that it looks different in men than it does in women. It may be the difference in manifestation that results in men generally remaining undiagnosed.

Abstract
Background
To examine the epidemiology of anorexia nervosa in men, we screened Finnish male twins born in 1975–79.
Methods and Findings
Men (N = 2122) from FinnTwin16 birth cohorts were screened for lifetime eating disorders by a questionnaire. The screen positives (N = 18), their male co-twins (N = 10) and those with lifetime minimum BMI≤17.5 (N = 21) were administered the Structured Clinical Interview for DSM-IV anorexia nervosa. The incidence rate of anorexia nervosa for the presumed peak age of risk (10–24y) was 15.7 per 100 000 person-years; its lifetime prevalence was 0.24%. All probands had recovered from eating disorders, but suffered from substantial psychiatric comorbidity, which also manifested in their co-twins. Additionally, male co-twins displayed significant dissatisfaction with body musculature, a male-specific feature of body dysmorphic disorder.
Conclusions
Anorexia nervosa in males in the community is more common, transient and accompanied by more substantial comorbidity than previously thought.
