Congratulations on your awesome loss!! And your new category!!
I have read a lot of threads on 3FC where people are nervous to say anything to a woman about losing weight in case they offend her. I have had people ask my husband if *I* lost weight!! I tell him not to tell anyone anything but come on, I have lost over 100lbs in the last 7 months so they'd have to be blind not to notice!
Your 24lbs definitely has to be noticeable, I am *positive* you'll be getting compliments soon.
Make sure you wear smaller flattering clothes too, that will definitely help people notice. I wore the same clothes for a long time even though they were getting too big as I couldn't believe I'd actually fit in smaller ones. No one could possibly tell at that point I had lost anything.
Good luck getting to your goal!!
