I've been on HRT for nearly 10 months and for the first 6 months saw basically little weight loss around the waist or muscles.
In the last 4 months I changed the types of things I ate, did a little more exercise and then things started to change. I have to say the majority of my weight loss has been my waist with the rest coming off the upper body. The limbs have seem some weight loss, but not as much compared to the torso. The extremities of the limbs have lost the least.
The visceral fat was the first to go, sub-cutaneous fat around the waist is some of the most stubborn to shift however, but it too is going slowly. I have lost also a fair amount of upper body fat and muscle, such that I am able to go down one band size (I wear my current bras at their tightest hook position for now). My upper arms are comparable to my SO's in girth now. The hips too have lost some mass, but this is probably more muscle than fat, I find it harder to get up from a seat than before and notice the thighs straining to get me up. My leg calves seem to be taking their time to lose the bulk though, but the muscles do seem to be a lot less defined.
