I have lost 88 pounds total. I have lost 10 inches off my chest, 15 inches off my waist, 5 inch off my arms, 8 inches off my thighs, 5 inches off my calves, and 15.5 inches off my hips.
In my experience, I haven't had any significant loose skin. By that I mean nothing that is apparent. I have a bit of looseness on the lower side of my arms, nothing bad, more an issue of toning my tricep. I have no loose folds of skin on my tummy , I have some loose skin on my thighs but, I am still loosing in this area.
I am actually REALLY pleased with my appearance and the skin issues were a big concern for me. I found that I lost pounds first, then my skin tightened up and I lost the inches.
I may feel differently about my appearance in another 30 pounds but, I don't think so.
I drink at least 3 liters of water a day, and drink the blueberry pomegranate drink or have the jello everyday. I was told the drink and jello have properties in them to help with the skins elasticity.
I also have significantly less cellulite than I did.
My stretch marks aren't bad but, my family doesn't have a history of them to begin with. I have a little bit on my bust which almost don't show (I have to be in just the right light), and a small amount on my outer hips. The hip stretches showed up when I was a teen and came about when I had really rapid height/growth spurt.
As expected, I do have a less full bust line than I did. Nothing I am embarassed by or worried about. If I didn't have a lift, I could still feel comfortable in my birthday suit!

(hopefully that isn't TMI.)
