doesn't BMI determine calorie needs?

Hi, I have a question. I find myself starving if I only eat the amount of calories MFP says I need, based on my activity level and my body weight.
Here's the thing though. They only info MFP has about me is my body weight and height.
They don't know how much of my weight is muscle mass and how much is fat. I know I have a lot more muscle than the average person of the same weight and height as me, because I do a lot of strength training.
Yet, MFP tells us both to eat the same amount of calories.
I feel like I need more calories due to my higher metabolism (due to higher muscle mass).
Is this a glitch over-looked by MFP that makes it impossible to truly track calorie needs and/or daily deficit and surplus?
I am starting to wonder what is the point unless MFP calculates a lot more info.
Also, MFP doesn't count the calories burned during strength classes, such as boot camp or Zuzka workouts. Another glitch that lends itself to inaccurate calculating.. Anyone else have issues with these things?

    1) BMI is based on height and weight. You mean bodyfat percent.

    2) Yes higher lean to fat ratios mean higher caloric needs. MFP's numbers are best estimates. They are not personalized. Best practice is to follow the MFP goal for a reasonable time period such as 3-4 weeks and then adjust calories as needed.

    3) Strength training calories are logged in the cardiovascular section by searching "strength training. " The strength training section is only for logging the sets/reps/weight used in your workout.

    Also boot camp could be logged as calisthenics probably. Have never heard of Zuzka.

    MFP assigned your calories in part by your stats, height, weight, age, etc. However, when you put in a weekly weight loss goal MFP subtracted 500 (1 pound) 750 (1.5 pounds) etc. An aggressive weekly goal equals a smaller number of calories.

    Another thing to consider, this goal is before exercise. When you add exercise, you earn calories. Calorie burns are rough estimates. These can be way off.

    Jemhh is correct. Give it some time and adjust calories based on actual results. MFP (and other sites) uses generalities.
