I know that genetics determine a dude’s hip width and collarbone length from the start...but can lifestyle choices during puberty (read: high body fat and low exercise) cause a hormonal imbalance (low-Test and high Estrogen) that would cause narrower shoulders and wider hips than what was originally planned?

Now at 19 theres probably nothing I can do about my rather pear-shaped bone structure, but I want to know if it didn’t have to be this way.
