you are burning around 600 too 800 calories.
Yes, you're under eating.
No, it is just a tad too little. You should eat at least1200 calories a day :)
Calories are necessary, but too many for a day is unhealthy. Some say 2,000 calories a day is good.
The body uses calories for energy. Naturally, the body requires many calories just to perform every day functions and to survive. If you take in too little, you won't have anything to burn for energy. Taking in too few calories (which, for the average person, is less than 1,200 calories a day or so) can lead to deprevation, modd swings, hormone fluctuations, starvation, and other health complications.
Yes! If you eat you take in calories. If you exercise, you burn calories. The problem is that many people eat too much and exercise too little.
There is no advantage.

It depends on three factors: your current size, age and the types of foods you eat to get the 1900 calories. If you are a teenage male 1900 calories may be too little to support your activity, normal growth and muscle building.
No, not at all. Most human bodies need about 800 to 1,000 calories a day just to survive, at the minimum. (Breathing, heart beating, simple movements.) When people do active things, ranging from walking to playing in sports, the body requires more calories to have enough energy to do so. Eating too few calories deprives the body of nutrients and can harm many organ and systems in the body.
Calories provide the body with energy and nutrients that are vital to survival.
Having only 600 calories a day will be a shock for your system, anything under 900 calories is classed as a starvation diet. You will not feel great, believe me. Also, having vitamins won't change the fact that your body will be lacking calories, having too little little calories will eventually cause you to gain more weight as it will slow down you metabolism.
