Just a little advise about the "overweight" thing.
I see all or most MtF absolutely want to stay thin and want to loose weight etc.
To me, additional weight is a bless. With the HTR the fat will move to the feminine places and will make you a body clearly feminine. You'll be a chubby/curvy/fat voluptuous woman. It will soften your face too. The passing will be way easier than if you are very slim ! Even if your face will still have masculine features for instance, with a voluptuous body, people will be more likely to assume that you are a woman anyway.
When I was younger, my mom thought that one of my cis male friend (with masculine face and haircut) was maybe actually a girl because he had this chubby/curvy feminine body...
I was born myself in a female body but basically had a very androgynous body : tall, long, skinny, athletic shoulders, very small boobs ...
I wanted to become more feminine, so I decided to gain a lot of weight which I succeed. Yes I gained a lot in my belly (which is cute and not disguting contrary to what society claims) but also in my thighs, boobs, arms, EVERYTHING, which makes my shoulders appear not broad anymore...My body is now absolutely feminine.
Really, you and all MtF, don't take additional fat as a curse, it's actually a bless for your feminization
