Vitamins don't have calories.... (at least not a significant enough amt. to quantify)
Teenagers are growing/developing, they need more calories than the average person. Probably 2x as much as what you suggested.
no, you wouldn't die...you'd just lead a miserable malnourished existence. Man, infertility at 16 is awesome! Permanently weakened bones prone to breaking is just the best! cerebral atrophy and stunted growth is amazing! Kidney failure! yay! Destroyed metabolism, whee! Dry, patchy, dull skin is just the best! who doesn't love losing clumps of hair!? mood swing? awesome! I can't wait to alienate all my friends!
so you might not die, but you'll sure look and feel like s*** 24/7.
Have you told your parents about your eating disorder yet? You should, cause girl, you are in over your head and you're gonna need all the help you can get to claw your way out.
Is your goal "not to die"? Or to be healthy? Because there's a huge gap between those two goals, and if all you are aiming for is the first one... that's going to be a problem.
Also, from your other thread, you are eating far less than 1200, throwing up when you eat barely enough food, you've lost your period, you are losing hair... so clearly what you are doing is very unhealthy. And could lead to death. I'm not trying to scare you - just a few months ago, we lost a member to her eating disorder.
Eating the bare minimum for a sedentary adult woman when you are an active teen is NOT the way to get better. Nobody is going to tell you that it's enough when it isn't.
Not much to add. Just going to second what the PP said.
It sounds like a starve-binge cycle. And it's clearly hurting you.
That thread was called "I need help". So clearly, you know it's not good. What we are telling you here is that eating 1200 isn't the solution. It isn't going to allow you to recover. It isn't going to prevent you from binging. It isn't going to bring back your period. It isn't going to bring you back to health.
A 15-year old girl who is 120 and 5'5" should be eating ~2100 if active less than one hour a day. If you are more active (especially if you are taking part in any sports), then you'd need to eat more than that.
CC's tools are not appropriate for teens (I used this calculator), and I'm assuming that you put that you were trying to lose weight, not maintain.
Getting in shape does not require losing weight, especially if you are at a healthy weight already. Eating enough, eating healthy, being active -- that is what it takes to get in shape.
Protein and Veggies, work out. 1600 cals is not enough. 1800-2,000, along with excercise is gonna keep you lean if not still drop some weight.
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
