Christians, how is an eating disorder defiling the temple more than getting fat?

I totally agree. Overeating and eating disorders are both unhealthy and harmful to our bodies. I struggled from overeating as a child and then turned to bulimia which evolved into anorexia into my teens and it still plagues me. However, I can't help but say it- I'd rather be unhealthy and skinny than unhealthy and fat.
