Anticipated bra change as weight is lost?

It doesn't sound like you're morbidly obese, having only 30 pounds to lose*, so your breasts might be there to stay. You may lose an inch or two of breast fat and maybe an inch or two of ribcage fat, but that would still give you 32DDDs, maybe DDs on a good (bad?) day. Breasts are finicky things, though, so who knows.

(* I don't mean to belittle your efforts or anything--just saying that if you had, say, a hundred pounds to lose, you could expect a more dramatic change.)

I am down slightly over 20 pounds (but still have 60 to lose). My underbust size is down 3" and so is my bust size. Since cup size is relative, that means my cup size is the same, but my band size has gone down by 4. I keep hoping that my cup size will come down faster, but no luck so far.

This appears to be idiosyncratic per person.; I have friends who complain that their boobs shrink faster than everything else.

At least with 30 pounds to lose you probably won't have to buy new bras several times. I am figuring on buying new ones about every 25-30 pounds and being resigned to them just not being quite right a lot of the time.

it's very individual... I know people who have literally lost their breasts.
However, when I was a size 6 i still had a D-cup. Now I'm DD. So I personally don't expect to lose too much.

But: I keep telling myself that this doesn't matter. What matters is that I'm healthy. I'd rather take an A-cup and be fit than keep my DD and stay where I am.

I was wondering the same thing! I have about 30lbs to lose also. Since i put on the weight my bra has gone from 32c to 34D (but that is a bit of a tight squeeze but determined not to buy even more bras!) I am hoping they will go back to what they were before i ut on weight as i had some really pretty underwear!!!!!! Hubby wants them to stay as they are, typical man!!

I lost around 25-28lbs and my bra size went from 34G to 32E... a huge change! I must have been holding a lot of excess fat in that area. I'm not sad to see it go, though, it's much easier for me to fit into certain clothes now that my measurements are a bit more average.

I want to loose 30lbs as well, and I anticipate to go down one cup size. I am currently a 36-38D (dependent on brand of bra) and when I used to be at my goal weight, I was a 36C - so really hoping this is what I go back down to. Hope this helps!

I went from 36D's at my HW (195 pounds) to 32B's at my CW (126 pounds).
If you have 30 pounds to lose I wouldn't be too worried. Get plenty of potassium (supports breast tissue growth), and do a little upper body strength training if you can - I didn't think I was that kind of exerciser (I prefer biking or walking) once I started the strength stuff my boobs got perky and round again!! They started looking a little 'deflated' after shrinking so much but that fixed them right up.

You're lucky to have big boobs and I'm sure you will be beautiful no matter their size. Don't let your cup size become your identity. No matter what happens, you are NOT "the girl with the big boobs" or "the girl with X size boobs" you're so much more to people than that!

I think it would be difficult for someone else to estimate how much weight you will lose from your breasts. Each individual is different. Some people gain and lose from their breasts first thing while others have little bra size changes when their weight fluctuates. And, of course, it all depends on how much weight is gained or lost.

Wishy-washy answer to a wishy-washy question.:laugh:

I have lost 21 lbs so far and went from an over flowing 38DDD to comfortably fitting into a 36DD. I found that when I had lost weight before and got down to 148, I still never got below a 34D. I really am ready to get rid of some of it and is a large part of my motivation for losing.

I went from 36D to a 34C now closer to 32C...perfectly ok with me since they were A's before gaining weight.
