I want to get a D cup naturally, is that possible? (photos)

Natural breast enhancement they're only are a few ways of achieving natural breast enhancement. One is weight gain another's pregnancy and the last is doing a surgical procedure to transfer fat from one part of the body to another. It's necessary to have enough fat to create a volume difference in the breast.

Unfortunately there are no creams, pills or foods that can cause breasts to grow. You can use certain bras and bra inserts to make your breasts look larger in clothing, but the only way to actually increase the size of your breasts would involve surgery in one form or another. 

Other than Breast Augmentation there is no way to add volume to breasts. Breast Augmentation is a very safe surgery. But sounds like this is not an option for you.  There are bras and inserts for bras that give the illusion of larger breasts. That may be the answer for you.

 I know of no way to increase the volume of the breast substantially without breast augmentation. From your opinion however it sounds like it's not an operation for you.

There is no way to naturally grow your breasts in the manner
that you are presenting. Breast enhancement surgery will be the choice for you.
It is very safe in this day in age if you are a healthy patient with no medical
problems. Eating in the manner you describe will not enhance your breast size
to the degree you are desiring or much at all for that matter.

Hellow  Rikkio  !Gain weight is not the answer, right now you have  two options, One is  a breast implant, ( those  are  very safe   in  this days )  and the  second one is to trafer fat to your breast, but you will need a donor area,  that minds extra fat some where else in your body.  Good Look 

Weight gain unfortunately will not all be where you want it.Only way to get you to a D cup is through augmentation with a breast implant.Nowadays it is the most common plastic surgery procedure and it is one of the safest as well.

Thank you for the question. As you can imagine, it is hard to know whether your current breast size increase is related to diet or not. It is also hard to predict whether you will be able to achieve a specific cup size will “naturally”. If, you are not able to achieve your desired goals through the measures you are currently utilizing, you may benefit from in person consultation with board certified plastic surgeons to discuss your goals and options. Make sure that you see lots of examples of their work achieving the types of outcomes you will be pleased with. I would also suggest that you do not communicate goals in terms of achieving a specific cup size; for example, a "D cup” may be the source of confusion/miscommunication. Best wishes.

Its difficult to answer your concerns specifically based on photos alone. For the best results seek the consultation of a plastic
surgeon certified by the American Board of Plastic Surgery. They have a website
listing all the certified plastic surgeons. Members of the American Society of
Aesthetic Plastic Surgery will all be board certified in plastic surgery and
have demonstrated an interest and competence in cosmetic plastic surgery as
well.

Sounds quite simple to me - pregnancy. That's the only way short of the unsafe surgery you want to avoid. How exactly to you figure eating a lot of fat will make the breasts grow without going elsewhere on the body?
