I once tried the starvation thing netwus let me tell you a little secret,It never works because once you finally eat your body grabs on to those calories much faster, And you gain twice the weight back.The only way to diet without eating, Is to go on a 7 day juice and water diet. But you need to drink things like slim fast during that time or you'll get too hungry. Also chewing gum helps when you're hungry too because the effect of chewing makes you feel like you're eating something. But you should never stay on that longer than 7 days. I really don't recommend it.
