I have been watching closely what I eat for about two months and doing a bit of starving from time to time. I also lost about 1" of my shoulders during that time without any HRT as well. I limited my intake of meat, especially fats - I would rather eat nuts, fish or raw eggs instead. By the way, if You are not doing HRT then You MUST take those proteins to remain healthy. One of my habits is that I never eat breakfest and I am trying not to eat after 8 PM in the evening either. If I desperately want something to munch down, then sometimes drinking a glass of water helps, because often body confuses thirst with hunger, or I munch down a couple of cherry tomatoes or a cucomber - almost zero calories and instant effect

And I have to admit, I have very good metabolism, but this might be because of testosterone and thus could go worse with time
