My personal experience with Estrogen & food cravings is two fold -
-on the one hand, interest in a lot of greasy, meaty type food has gone way down (cheeseburgers, drive thru, etc.)
-on the other hand, interest in chocolate -& specifically chocolate, not other sugary items, but specifically chocolate- has gone WAAY up.
So, pretty much, my appetite doesn't bother me - until I need a chocolate pick me up - which fixes things & then I have to eat some protein / veggies / etc. along with the chocolate in order to not cause blood sugar fluctuations. I'm not diabetic and my A1C is fine. But seriously, there is an Estrogen / chocolate connection -- before starting Estrogen I enjoyed the occasional treat, now I'd eat it nonstop if I could.
As for my weight, it kinda did a yo-yo thing. Before transitioning at all, I was overweight from being depressed & eating crap all the time. When I first started transitioning a combination of better diet, happiness, increased activity & not wanting crappy food helped me to lose a lot of weight & I was really thin and looked really good. Years of Estrogen and chocolate, however, has caused me to gain weight again, which I don't like - but I'm still less than I was before transitioning & I find that with the Estrogen, my body carries the extra weight better.
But yeah, Estrogen and chocolate have some bizarre relationship I do not yet understand...it must be chemical
