It's even worse during the fat loss part of the process because body fat stores hormones that get dumped back into your system while you lose weight.  They probably hear that and think "extra hormones? great!!" But wouldn't their body produce extra female hormones to compensate? It's not like they're on blockers. I honestly can't think of any trans guys I know who aren't chubby. Some trans women are, but I guess the Ebbl (it's) PATrichary has body shamed them into not being butterhuffers.
