Diet ?

k so I want to lose weight like super bad. if I eat nothing but 1 piece of celery a day and water for one week, how much weight do you think I'll lose? or will I have to do it for a longer period.

and please don't be like"oh that's so stupid don't starve yourself" I know its stupid, but I've been doing it for 3 days already and its the one diet I've ever stuck to.

i just want to know how much weight you think I'd lose.
