I'm sorry to say that even taking it slowly losing 111lbs has left me with permanent loose skin, that only surgery will correct. Really, the only bad place is my stomach and I think that is from being obese - losing weight - getting pregnant - getting obese again and losing weight. Sadly, though, I will never wear a bikini.

Some of it will tighten up, but some of it won't. The fact that your not say, in your teens or 20s will make it harder, as your skin is losing elasticity now anyway.

The health gains are worth the loose skin and wrinkles, though.

Time and increased lean muscle mass will take care of most of this issue. The biggest thing is to be patient. Not sure how overweight you were, but in some cases I would imagine that there will be some permanent loose skin.

I lost about 80 pounds but I lost it slowly so no problems with the face in this regard. Abdominal fat loss was an issue with loose skin. I'm 38 and have thick skin. The thick skin helps. Younger bodies respond better also. I believe you'll see the majority of recovery due to skin elasticity after 3 months.

I ran across this website not too long ago. I'm not really sure what to make of it. Even if he is correct, you would have to get your bodyfat percent pretty low to have a strong effect.

I hope he is correct, because I'm halfway to goal and my tummy is a little scary. Oh well...

Don't be afraid of loose skin...if it does become a big problem (rare, most people lose weight without much loose skin issues, and it solves itself over time, especially if you build muscle as well) there is always the option of surgery if you are comfortable with that. Which may not be "natural" but being that obese wasn't natural either. I'd say the cost of surgery would be worth the happiness and confidence you would get from it as long as you were confident in the surgeon. But chances are it won't be a problem because you can see many pictures of people who were fat and became very lean and muscled without the slightest hint of loose skin.

I had the same problem (caused by pregnancy). Core strengthening exercises, like sit-ups, lunges and crunches helped a lot. And yes, time helps too. ;)
