Check out your Basal Metabolic rate. Your resting rate for calories assuming you are 30 year Female 5'2" 140 pounds
your BMR is 1406 calories a day. In order for a diet to work you need to creat a caloric deficit. I know on Atkins you can get away with about 300 more calories than BMR. If you are active and are working out you can multiply your MBR by 1.2 or 1.3 to get a new level. The BMR is what is reqwuired to run your body. In order to lose weight you need to cut your BMR by 10%. One pound of fat is roughly 3500 calories.
