After a 10 lb loss, I noticed that my boobs had shrunk. Also, the armpit fat on the left side of my body has disappeared, but I still have a fat roll under my right armpit. Weird.

Most likely it's because you're not wearing the correct bra size and you're probably not leaning forward and scooping all your breast tissue into the cups in the bra. ;)

Typically women think that they have back fat/underarm fat when it's really migrated breast tissue from wearing bra bands that are too large and cup sizes that are too small. What is your underbust measurement?

My losses so far are pretty small in the grand scheme of things however, I already notice my jeans are looser in the thighs and waist and my puffy tummy has gone down. It's still loose as all get out after years of being way overweight/obese and two kids but! It's not protruding all the time either.

Also, my face looks less puffy overall.
