Is there a safe way to be anorexic?

I've been struggling with my weight my entire life and I'm sick of being severely over weight. Due to a recent sinus infection I haven't been able to eat in the past couple weeks causing some weight loss. I've heard about religious fasting where the church goers refrain from eating for long periods of time and I haven't heard of anyone dying in my community just yet. I figure if I eat perhaps once every other day I'd prevent any serious damage to my body but I'm not quite sure. Suggestions?
