Yes, you're under eating.
Yes, very much so. The average person should be eating 1,500 to 2,000 calories a day. Eating only 600 to 700 calories a day is starving your body of the proper nutrients it needs and is very unhealthy.
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.

It depends on how long the 160 pound female eats 600 per day for. If this helps 1 pound = 3500 calories
600 calories is about 2.51 kJ
233 days assuming you burn 600 calories per day:* 1 lb = 3,500 calories 40 x 3,500 = 140,000 calories 140,000 / 600 = 233 days *The actual number may be less if you are working out because muscle continues to burn calories after workouts.

3500 calories make up a pound. So, if you burn 600 a day it would take you a little less than 6 days to lose a pound ( 3500/600= 5.83333) Keep in mind that this only remains true if you are burning more calories than you are consuming.
about 500-600 :( so little
100 g of chicken breast, meat only, boiled/steamed is 165 calories. so 600 grams would be 990 calories
Yes its 600 CALORIES!!
