I'm only 6 months on hormones and I started with a face devoid of fat and I think it pretty much stayed that way. Face fat is also the most important issue for me as far as I'm concerned.
Whenever I gain weight, it goes straight for the belly, the waist, the butt... and that's where I lose it first as well. If I really puff up then a bit goes to my breast and then goes away if I eat thin again. Face, nothing so far... so personally, I haven't had any success with the gaining weight strategy, and gaining weight makes me not like my body shape and not feel as good physically as I do when I eat thinner.
i.e. when I eat low fat high carb (basically a lot of whole fruits) I've got energy and I can run and feel light and athletic, when I eat high fat foods I feel heavy and get more depressed...
And I think, the transition is hard enough as it is. Sure, the fatty food provides instant comfort, but then I feel horrible for a few days. I found it better to do what makes me feel good right now and hope some fat will reach my face eventually. At the moment, it seems I would have to gain way too much weight for my own comfort level to get face fat.
So I'm just focusing on eating healthy, getting all my nutrients and make sure to get all my calories and that they come from good or at least decent sources and be active - running every 2-3 days for 30 minutes or more and doing a bit of aerobic exercise every day. Sports and good nutrition help take my mind off the transition a bit and stay a bit more focused on taking care of myself.
Before I did this, I was just crying all the time non-stop and wanted to die. Perhaps the estrogen increased my tendency to be depressed. It's really dangerous to feel like I did and I don't want to go back to feeling that way all the time.
