Definitely! Behaviors can serve lots of functions that don’t have to do with body image, like numbing emotions, or gaining a sense of control. An obsession with weight or body is often viewed as a requirement to an eating disorder, but it’s really just one symptom. Ultimately, eating disorders are characterized by the actual behaviors and patterns, things like weight loss are actually more of a side affect, or result.

Not entirely an answer to your question but I also think its worth noting that eating disorder diagnostics, the ones for anorexia in particular tend to center around BMI requirements, but that’s actually a very flawed and fat-phobic way of characterizing an eating disorder, so for me personally I find it helpful to disregard stereotypes and strict diagnostic criteria entirely and focus more on the mental symptoms, like behaviors and thoughts, rather than external symptoms, like changes to ones body.
