Any good response for "wah you've gained weight"?

I'm not one of those lucky mums who can shed off the post-pregnancy weight gain. Post-partum depression hit me hard, so staying fit on top of taking care of my baby without helper or family's help just wasn't on top of my list. Just went to a wedding and the first thing my inconsiderate aunt and uncle who haven't seen me in years since covid was "wow you've put on weight", in front of other relatives. It was embarrassing and hurtful. It's not something that can just be ignored and then move on from. I was self conscious throughout the wedding dinner, and I am already dreading upcoming Christmas and Chinese New Year family gatherings where they may be more of such unnecessary comments from others. Realistically I will not be able to go back to pre-pregnancy weight in time. So...***Are there any sassy witty mums here with a good, helpful comeback?*** A response that lets them know it's not okay to shoot their mouths off this way?? I don't wish to just smile and nod and say "ya lor", then feel embarrassed and self-conscious throughout the gathering. If your advice is to ignore, no that's not practical. If a person says to you "Hey you've gained weight!", you can't just treat the person as invisible and pretend you didn't hear. You can't just stay silent, you also can't ignore and just walk off. To those advising to slim down by doing exercises or to face the truth, yeah sure don't worry, am in the process, but that's not the reply suggestion I'm seeking here. Thank you in advance for those with practical advice (instead of "just ignore")!!!!!🤗
