The only way I've been able to tell visually so far are before/after pictures. I'm down 55 pounds after 6 months (diet and exercise) and I don't feel like I've noticed changes in the mirror. However, I've gone down a number of belt sizes and the pants I previously wore around my waist can now be worn comfortably over my gut. Visually it only occurred to be because a friend sent me a picture from a dinner I had with them and I saw how much smaller I looked.
