I definitely found both that E made me hungrier (and gave me new cravings) and that I put weight on more easily now. I don't mind the extra padding on the curves, but I could really do without the belly as well! My metabolism cratered on HRT, and I was still used to eating like a teenage boy when I started.
On the other hand, I'm sure losing weight would come off the boobs first, with my luck, and that's what balances out the belly (I'm 42DDD and it's *just* enough to distract from elsewhere IMO, which is annoying).
