Weight loss and hrt

I am preparing to get on hormones and I'm currently trying to (healthily) lose as much weight as possible before I start estrogen, as I understand that Hrt will probably lower my BMR. Do any of you all have experience with losing weight on hrt?

I'm mostly doing this so I can get a more feminine fat distribution, and have heard that E doesn't really redistribute existing fat that well. I've also heard that losing weight while on hrt can also help with body shape (and yes, I am working out my glutes). Any tips?
