bmi charts don't take into consideration muscle or bone size for that matter so your ideal weight is dependent on more than just the
bmi chart.
I'm guessig your still a teenager, so I'd really caution you against being overly concerned about the number on the scale as yout
body is still growing and changing, and having proper
nutrition at this age is important.
I'd really focus on what you say you've beendoing - eating right and exercise and feeling and looking healthy and not being overly concerned with what the scale says
