TheLindsy you could lose weight on 1400 calories a day

I think you're confusing BMR with your actual calories burned. There's no way 1500 is maintenance for you—especially if you're hitting the gym!
Remember, your BMR is what you would burn just existing; if you did nothing else. Even if you are sedentary you multiply this number by 1.2!
Use this formula to find out what your BMR is:
Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )
Then when you find out that number, multiply it according to the following:
If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
Those will be your calories to maintain

subtract 500-1000 to figure out around what you would need to lose weight.
For example, my BMR is 1356. I am very active, but I believe I'm somewhere between the moderate and very active range, so I multiplied my BMR by 1.6 and get 2170 calories to maintain.
granted we are not machines so each body varies, but generally you'll find you can eat more than you thought and lose weight.
When I was 125 pounds I was eating 1600 calories and still losing weight!
