When I started HRT I was in the mid 200s, and muscular, and overweight. Muscle began melting off of me very early on, and so did the fat. I dieted intensely, giving up sodas and sugar and high-carb stuff, eating mostly vegies and meats/seafood/fish in a sorta paleo diet thing. About a year in, my belly fat was gone, and so were my love handles, but my boobs had also lost some plumpiness, and my face was thinning again, too.
So, I decided at that point to try to gain weight, as long as it went where it should on a woman, and not back onto my belly and sides. I increased my healthy fat intake, resumed eating multi-grain breads and cereals, and added dairy back into my diet, also.
That did work, and I was up to a small C cup again. But as even more muscle melted off, and I came to realize that my bones and body shape were that of a tall skinny woman, not a shapely, curvy girl like the Kardashians, lol. So, I then decided to just be as healthy as I could be instead of trying to be that which I could not. I am now in the mid 100s, having lost about 90 lbs since the start of my journey, with a BMI of almost exactly 20. But my boobs have shrunk down to small B's, maybe even smaller, and my butt is almost gone, too. This is how my sisters are shaped, and how my mother was, too, no butt, no hips, just a beanpole look, sooo I feel I have that at this point, I have arrived at my full genetic potential.
Buuut, my shoulders were widened by T, so I think it in my best interest to have breast and hip and butt implants at some point, though I hate the idea of cutting up my boobs, especially, I like them as they are, and I usually wear padded bras to make up for what I lack proportionally, and I choose clothing that enhances my silhouette, and give me the desired hourglass look. Still, that doesn't work with a bikini, and I am a beach bunny by nature, sooo, yeah, someday after my face is remodeled, there will be implants top and bottom..
Sorry to ramble, but the whole 'body image' thing is pretty involved, and HRT might just be the first step of many along the way..
Some girls get all they need shape-wise from HRT and exercise, but I was not one of them..
Hope this helps...
