900 calories is way too little for a growing teenager or even an adult. If its weight loss that your looking for, then you should try eating fresh veggies and fruits, and eat around 1000 calories.
Hmm that doesn't sound good. You need to give your body nourishment in order to loose weight, so you wont over eat. I say that 1200 calories if PERFECT

You lose weight at first, but after a while your metabolism would get used to it and stop allowing you to lose weight.
I would lose muscle mass and my metabolism would be shut down.
