And as for your questions, if after a year of maintaining at a healthy weight, and your skin still doesn't tighten up, usually the only option is surgery. Possibly chest exercises would work to tighten, but I really have no idea about those.
I don't mean to sound rude. As someone who has been there/done that, it's the most likey scenario I can think of.
Another consideration (as a 5'8" woman myself), there is not enough fat on your body to fill out your chest. Breast are made of fatty tissue and you starved all that away. Now that it's gone, you have excess skin with nothing to hold up.
Colbers is right that if the skin doesn't tighten back up within a year, surgery is the only option.
Now I apologize for subsiding your question, but this type of weight loss needs to be giving you a wake up call. Why do you think I'm trying to lose weight now? Because I did exactly what you did 3 years ago! At any rate.... to answer your question. You can't fix your boobs. They do need fat.... but one exercise that can help are flies. Also chest presses, and the bench should work to firm up your pecs... .not the boobies though!lol
Hopefully when the weight comes back and even more after you stop starving yourself, which will hopefully be soon, you'll appreciate who you were really were and how you looked before you took that approach.
You should also supplement with Omega 3-6-9 pills. it the good fat that your body needs and it should help to tighten the skin.
pectoral flyes with dumbells or on the machine
building up the muscle under the breast can help lift. I've noticed improvement from working out my chest 1-2 times per week.
I'm about 1/3 of the way through a large weight loss goal, and it's really starting to show. I was concerned that I was going to lose my boobs as I lost weight, but so far, not so much -- and in fact, my hubby complimented me recently that I was really starting to tone up my chest and my boobs looked great! All I've been doing is light-to-moderate strength training at my local Y. I imagine the chest press is the machine most responsible for toning up the breast area, but just having a more overall strong and fit body is doing wonders.
Best of luck in working towards your strong and fit body.
i was there about 4 years ago. and these people r right. i however am only 5'2. i was down to 87 pounds and i started at 115. i gained 40 POUNDS! in like 4 or 5 months wen i desided to stop starving myself. i shouldve taken a heathier aproach to gain weight back. my advise to you is to slowly eat more, eventually you'll be back at a healthy weight. what you have is a disease, not a diet, just focus on being heathly. heathly healthy healthy. i am now 120 pounds.. and still trying to find a perfectly happy weight. once you get ur weight back.. get a boob job lol, best thing i ever bought :) good luck!
Im 5'8 and used to be 165,... you had me till... starving yourself
