I've lost 12.5lbs and 2" so far, and personally I can't really tell that much in the mirror. Maybe a little in my face... but my engagement ring is fitting much looser... I will probably have to get it resized soon. And, a lot of my size 24 pants are getting loose... I may have to actually buy a belt. However, people around me, my fiance and his family have been saying that I look like I have been losing weight... I just can't wait until I really start to see the difference in the mirror!!
When I was at 260, I lost 30 pounds before anyone noticed. Then, a whole bunch of people seemed to notice at the same time. It was weird.
To be honest, I didn't see it at all. I had to lose 50 pounds before I could look in the mirror and truly see a difference. And now, at 80+, I still don't look in the mirror and see a huge change. I still look fat to me.
Don't trust your eyes. Trust your scale, or even better trust your clothing.
That's why it is good to take pics. You see yourself every day, it's going to be a while before you notice a change. And like others have said, when you have more to lose, it takes longer to notice. But when you have those pics you'll be able to see it much better.
