Its not always a comfortable conversation with people regarding weight, just like the “how many months pregnant are you” is seen as innapropriate to ask, saying “wow you’ve lost a lot of weight” is innapropriate to ask when they don’t know if you are losing it on purpose, yay! or there is something else going on like “oh i just haven’t been eating since my entire family DIED in a PLANE CRASH” then that’d be awkward for them
