Is it possible to lose this amount in a week

Don't answer please if your going to be negative!I am going somewhere important in a week and I was wondering if I eat less than a 100 calories a day until then will I be able t drop 8lbs?

yes I know this is dangerous and all the risks but that is not my question, my question is it possible to lose that amount? and if more?
