What is your height, weight, and BMI? One word of caution, you know your BMR, but that is only what your body needs to at rest with no physical activity. If you start an exercise program, you will need to adjust your calorie intake accordingly. The suggestion of subtracting 500 kcal from your BMR is a good start, but could be unhealthy. This is really disheartening for most people to hear, but you need to burn 3500 calories to lose 1 lb of fat. Not easy by any means, but with the right diet you can do it. Also, portion control is a must if you plan to lose any fat while still maintaining muscle mass.
