I'm curious too, what's the thing with visceral fat? Other than it being an unhealthy way to carry weight and the interesting little thing that I have never had much of the stuff, not even when I was on T dominance before transition. I've had partial female fat distribution since my teens and nearly all appears to be subcutaneous rather than visceral from my observation. (Slimming down makes my tummy and waist tiny while I still have stuff on thighs and hips and so on.)

Its interesting because we want to nuke the visceral fat if possible anyway as its just not healthy to have much of it... But about breast development? New information to me so please do tell.

Never heard of visceral fat so I looked it up --it's deep belly fat around your abdomen 
"How can I reduce visceral fat

The best way to reduce visceral fat is through losing weight and diet. Visceral fat responds better to diet and exercise than fat on the hips. Regular exercise can also stop visceral fat from coming back.

Another option is medication, but studies show this is not as effective in reducing visceral fat as exercise. Liposuction does not work to remove visceral fat.

Even though you cannot change your genetics, hormones or your age, you can reduce your risk of disease by:

exercising for at least 30 minutes every day (for example by brisk walking, cycling, aerobic exercise and strength training)
eating a healthy diet
not smoking
reducing sugary drinks
getting enough sleep
won't affect fat around hips
