Highest I ever was put me just into obese category: 200lbs (BMI of 30.4). I already had stretch marks from pregnancy, and it was/is BAD. Before I really took care of my health, I think I averaged about 150lbs post-baby. I started a catering job, and the boss was constantly feeding us and I just stupidly packed on the weight in about a year and a half.  Went from 200 to 140lbs in 10 months. I already had stretch marks (many are still still red after giving birth 16 years ago - trying retinoids to heal them FINALLY because nothing else has worked). I was 24 when I started learning about proper nutrition and health and began the road to fit status. No sagging skin because I eat fairly well, drink mostly water, and take care of my skin bc of stretch marks. It took maybe 3 or 4 months after all the weightloss to get my skin to tighten up again, and it wasn't really that bad, just lower abdomen and tippy top of upper arms.  Stretch marks are the reason I have yet to get verified though :( They're so bad, they'll bleed if I scratch too hard. My fiance and I want to have kids in a couple of years, and I'm terrified to get pregnant again because the skin on my abdomen is so stretched that even massage hurts it (and the bleeding). Umbilicus is 27-28", and it's worrisome to think what would happen if my skin is still this frail and is expanding to accommodate a mini-me. The retinoid cream seems to be helping, but I've only been using it a week.
