How much weight can I lose in a week eating 500 calories?

I'm 5'2, 125lbs, female & 16. Don't preach, I know the cons. I want an actually answer so if you're going to rant about it being unhealthy or whatever please just don't comment.

How to Lose Weight as a Kid

Recommended Answer:

A lot in the 1st week (1 or more lbs), some in the 2nd week, a little in the 3rd week, and then the loss trails off.And when you start eating normally again, watch out!If we could only lose weight - as much as we want -- by just cutting calories. I agree that it works, but doesn't seem to be permanent solution.In theory, a lb of fat is about 3,500 cals. So, in theory, cutting 3,500 cals a week -- we'd lose a lb every week, for as long as we want. However, in practice, the body eventually adjusts to the new caloric intake.Still, diet is 75% of my weight loss success. Wish there was an easier/simpler answer.
