The closest thing I have to a phobia is to voluntary self-starvation. I can’t interact with an axorexic in any sort of normal fashion very long, and even TV programs or articles will throw me off-balance. It takes me several readings to finish stories dealing with voluntary self-starvation. Yet the subject’s like a moth to a flame for me, and invariably find it interesting. Like this story about a diet called LighterLife. You get 500 calories a day. That’s it.
The rapid weight loss is not arguable, but there’ve been stories of severe side effects, including vision problems, rotten teeth, and death. One lady’s death has been attributed to a weakened heart due to lack of protein.
