I’ve always been insecure about my side profile and I’m seeking advice on how I could improve it. I’m roughly 5’9, 168lbs (down from 250lbs).. I definitely have an anterior pelvic tilt, forward head posture and an overbite. I had braces at around 12yrs to fix buckteeth. Could my issue just be caused by my posture/weight? Or do I require surgery? If so which procedure?
