I think the greatest compliment for me is "You're beautiful." I also got called "skinny mini" this weekend from a friend I hadn't seen in a while. That secretly made me feel good!
Also, I spent this summer at home for the first time in a year or two, and I ran into some old friends/acquaintances. The first thing they'd ALWAYS say is, "Courtney! OH MY GOSH HAVE YOU LOST WEIGHT?? You look so good! Oh, and I've missed you!" Haha...I didn't realize what a big difference it was and how noticeable it is...
The worst? My mom...she would always be like, "I wouldn't wear that if I were you...you can see your rolls." She'd always comment my clothes or jeans if I had muffin top. She was my worst critic I think...
