I am 16, 5'8 and I weight 175 lbs. I found online that I have a larger body frame if that means anything. I swim so I have a bit of muscle in my body. The BMI says I am a bit over weight, but I think losing 15 lbs would be good, but I think that's still considered over weight. I have no idea. I look healthy, and feel healthy. I've just go a bit of stomach chub that never goes away.
