If you eat 200 to 500 calories a day and burn 1000 how much weight will you lose?
If you eat 200 calories a day and burn 1000 calories a day, you will lose 1.6lbs extra a week.
(((200cal-1000cal=-800calories burned a day
-800*7days=-5600 calories burned a week
-5600/3500(calories in 1lbs)=-1.6lbs extra lost a week)))
If you eat 500 calories a day and burn 1000 calories a day, you will lose 1lbs extra a week.

**I say "extra" because depending on your bmr(calories burned everyday just by being awake/sleeping) you will lose more weight.**
I would say on average on a diet like this, you will lose between 3-6lbs a week.
