Worries about losing weight!

I don't speak from experience, but as far as I am aware skin loses its elasticity at some point. Just like a rubber band that won't go back to its original form. So perhaps some skin will still be able to move back. Perhaps you can also fill out some of that skin by growing your muscles.
There are however no exercises that reduce excess skin. If it is really bad surgery might be your only option.

I don't speak from experience either, but from what I know, if you lose weight gradually (say, 1-3lb/week), the skin being elastic, will just shrink back to accommodate for the new body size. When I hear of problems with loose skin, they are usually caused by the fact that the person lost a lot of weight very quickly, think crash diets & no exercise, and the skin hadn't yet had time to adjust.
But in any case, even if you lose in total 150lb, you will lose them 1lb at a time - so you can see how your body changes at all times, and you can adapt your weight loss strategy and goals based on how you feel. Good luck!

I'm in the same boat! I have 140lbs to lose and I know I'll be healthier but the extra skin idea freaks me out. I've been told that if you lose the weight slowly it won't be as bad and with weight training you can tone a lot of it up.

It depends on a number of factors including: how long you have been overweight; how old you are; how fast or slow you lose weight; and the big one - GENETICS.

You can mitigate loose skin a little bit by losing slowing, lifting weights to maintain muscle mass underneath the skin and taking care of your skin (moisturizers, etc.). Also, your skin will continue to tighten up for about 2 years after weight loss, so you won't know the full effects until much later. However, how much loose skin you have in the end is largely determined by your genetics.

All of that being said, being a healthy weight with loose skin is still the FAR better option than being overweight, wouldn't you agree?

I've lost 95 pounds over 3 1/2 years so I have the slow loss going for me. However, I have been overweight my entire life and I am no longer in my 20's (in fact, not even close). ;-) I also apparently don't have good genes going for me. I have a lot of loose skin on my belly, upper arms, elbows and thighs. While I don't particularly like to looks of it, I wouldn't trade my new, healthier body for tight skin ever! I still have 23 pounds to go, so we'll see where I am in the end, but I don't expect my skin to tighten up as much as I would like it to. I feel incredible though. The benefits of my weight loss completely and totally outweigh the look of the loose skin. Besides that, only my husband and I see the loose skin and he's been with me since my heaviest and this is definitely an improvement!

It depends on a number of factors - genetics, your age, how overweight you are/were, how long you were overweight (how long the skin was stretched). But as the others said, it is better to have extra/loose skin then the health issues that come with being morbidly obese.

I have loose skin, and come into this journey 64 lbs ago expecting that. I have had 3 pregnancies and 3 c-sections, with lots of stretch marks and scars from those pregnancies. So as soon as I began trying to lose weight, I began saving money for a potential tummy tuck. When I reach goal, if I have lots of loose skin, I have the option to consider surgery. If I don't need the tummy tuck after all, bonus, that saved money can be spent on a brand new wardrobe or a trip somewhere.
