How much should I weigh...?

I'm 14 (turning 15 in September) and 5 foot 8.
Currently I'm 165lbs but I want to loose weight because I be aware of kinda... above weight average for my age and echelon (despite what a site I used to indicate my weight-for-height said)...
So what would you say I should be around weight-wise?

140 pounds is about right for your bulk if you are an adult, but if you lost 5-10 pounds you'd be fine. I wouldn't recommend trying to lose any more than that to someone your age, you don't want to mess next to your metabolism while you're still developing.

You're really not too overweight considering your height. Your BMI is 25.1, which is just overweight. I would try losing 10-15 pounds at most..Maybe not even that much. You don't have to be a barbie doll that weigh 80 pounds.
