So I'm in a sport and I work out with my team mon-fri, also I normally go to the gym and run on the treadmill and do upper, lower and core workouts. Recently I've gone on a diet to lose weight because I was tired of feeling fat and flabby. So far I've lost about 15 pounds in 5 weeks, but I've been on a really low calorie diet (like 1000 or less). I've heard that eating really small amounts lowers your metabolism and working out raises it. I feel okay, like i dont feel starved or like I wanna pass out. So am I eating enough? If I'm not then how much should I eat and what are good things to eat that promote weight loss, keeping in mind that I'm also an athlete. My stats by the way are 16year old female-5'8"-130 pounds

No, you are not eating enough.

1. You are already at a very healthy weight for your age and height

2.  You should be eating at 2200 calories per day -- and you would still be losing weight, which you don't need to do.

3. 1000 calories is almost starvation. Among all the other things involved with starvation -- it kills.

Some stuff about starvation:

Adequate nutrition has two components, necessary nutrients and energy in the form of calories. It is possible to ingest enough energy without a well-balanced selection of individual nutrients and produce diseases that are noticeably different from those resulting from an overall insufficiency of nutrients and energy. Although all foods are a source of energy for the human body, it is possible to consume a seemingly adequate amount of food without getting the required minimum of energy (calories).

Since the body will combat malnutrition by breaking down its own fat and eventually its own tissue, a whole host of symptoms can appear. The body's structure, as well as its functions, are affected. Starved adults may lose as much as 50% of their normal body weight. Characteristic symptoms of starvation include:

• shrinkage of such vital organs as the heart, lungs, ovaries, or testes, and gradual loss of their functions
• chronic diarrhea
• anemia
• reduction in muscle mass and consequent weakness
• lowered body temperature combined with extreme sensitivity to cold
• decreased ability to digest food because of lack of digestive acid production
• irritability and difficulty with mental concentration
• immune deficiency
• swelling from fluid under the skin

After your bones deteriorate and your reproductive organs become so atrophied they don't work, your other organs, including your brain will be permanently damaged. You will end up as a stunted adult with brittle bones and infertility. 

^^ what coach k said, to the max. Your weight is perfect, you could even weigh more and still be perfect, if that's what's worrying you. Please stop what you are doing to your body NOW. You do not want it to continue, nor do you want it to get any worse.

If you eat 150-300 calorie meals every 3 hours and eat a good balance of protein fat and carb i garuntee you wont have to eat only 1000'a day. I was diagnosed with gluten intolerance this year and it was hard to prepare really large meals so i started to do it and lost a bit of weight and it was because now my metabolisms super fast and my body wasnt in starvation mode like many teen girls are simply by ignoring hunger. Working out helps your metabolism but shouldnt be relyed on in order to keep it from shutting down, which is why your only eating that much yet arent always hungry
