LOL, all of the POS saying, "gyno." You're really jealous. Even if that is gynecomastia, it's barely noticeable, except to the guys obsessing over other guys' chests. Awesome physique, Abed!
Definitely don't worry about 18%, lol. 14ish with the new pics. I believe it's bad lighting for you. You probably look leaner in better lighting (just a guess).
Congrats on the lifestyle change. I've seen some guys actually hide the bottom part by pulling up shorts/pants over the bottom portion, essentially hiding the loose skin. Economical solution if you...
