One solution are implants, of course.

But not all breasts are made alike. Some contain more gland tissue, others more fat. Also, fat deposition in the body, and consequentially, where a person looses fat first and foremost when they go lean, depends mostly on genetics. Their body might favor reducing fat around the abdominal area first before going for the breasts.

That being said, when you go this lean, breasts size will most likely always be affected, but all the above factors may contribute to a person still maintaining a decent size.
