It's considered rude to comment on things like that, so many people won't do it. You never know why someone is losing. They could have cancer and not be thrilled about the congrats you give.
When you're really big, you need to drop a couple sizes before people notice. I was size 24 and nobody really said anything until I was a 20 and I didn't hear a lot until I was 18. When I was a solid 18 - that's when I started hearing comments all the time. My hats when people really noticed.
Other than saying, "You look great!" people really should stick to saying nothing because a lot of what they say is just...not really very nice, lol.
"You really were a porker!"
"No, she was REALLY FAT! She lost a TON! You should've seen her!"
"You have such a nice waist now! You didn't have one before!"
"Now you walk like a woman. You used to waddle."
It's really hard to thank people for some of that, lol.
I will never say anything other than, "You look great!" again.
