I would like to advise you to go about that in a better way, if you're looking to lose weight, fine, but doing it in said manner isn't the way. It's hypocritical of me to say, but I'm saying it to try and prevent you from making the terrible mistakes I gave and still am. You might lose weight, but you also lose your ability to go about your day to day activities. Depending upon the severity of your situation.

Do yourself a favor by just eating, and exercising. You're not going to look any better by just no longer eating.
