what makes this a bad idea?!

if you starve the weight off, which you are doing at 1000 cal per day, you are much more likely to gain the weight back. slower weight loss is more sustainable, because you build healthy patterns that you can continue with. don't be in such a rush.

if you don't eat for a little while, your body will rob its protein, carbohydrate, and fat sources for food. It will also lower your metabolism and make you more susceptible to disease.

There is nothing wrong with that.

You would be hungry alot of the time. That's pretty much it though.
