i don't believe it's possible to live on that for the rest of your life. fasting will get rid of your excess fat, and if you don't take in enough calories and fast for too long you will just start starving.starving=death. although that is a great feeling, you do have to go back to eating sometime. you have digestive organs for a reason, and you're body is made to ingest food. you will get very close to that feeling if you eat a raw vegan diet, so if you really want it that much, do that. i saw you posted this on the anorexia/bulimia forum, so i hope all is well with you... God bless.
