Too low calories: You should not go below 1000 calories a day. You need to exercise also. You need to burn off 3500 more calories than you take in.To loose 1 pound a safe weight loss is 1 - 2 pounds a week. Good luck.

Note:: Restricting calories below your base metabolic rate triggers starvation mode for the body which causes you to overeat when food is available. You may lose a little weight at first but then the body will try to store fat to fight starvation--you'll gain it back and it will be harder to lose. Best to work with a nutritionist/health coach on a life plan for steady healthy sustained weight management.
