I only got an increase in appetite the first few months on T, then it got back to "normal" again. I say that in quotation cause my normal appetite is very, very low. I feel physical hunger but somehow my mind doesn't really register that for what it is, and eating is only a need for me never something I actually want or look forward to. So when I got an increase in appetite on T it just barely got up to the point of "maybe I actually do want to eat, for a change".
But I have a very slow metabolism (which didn't change on T as far as I can tell) so I gain weight very easily even if I eat very little, but then I also do eat next to nothing cause of my lack in appetite which makes it easier fo me to stay at a healthy weight. I have also only gained a very minimal amount of physical strength and/or muscle mass from just taking T and not exercising. My little sister who's also a couch potato is stronger than me, as a reference. I've struggled with both my slow metabolism and an eating disorder though, as well as my lack of appetite, so my weight has been fluctuating a lot and still does somewhat, but I've only briefly been overweight and never actually underweight just very close to. So mostly I've still been within the healthy range, just all over in it.
I'm not entirely sure of what my body type is, but the kind that gains fat easily, mostly subcutaneous and it mostly stores on my butt and thighs. I look thinner than I actually am to others because I don't really store fat on my upper body or face and that's what other people tend to see/focus on. So I'm like a pear-shaped endomorph, kinda. I had an extreme pear shape before T, and now 5 years on T I look kinda hour-glass minus tits, due to fat redistribution. (Same shoulder and hip width, narrower waist).
Short answer: it basically didn't make any difference for me how easy/hard to lose/gain weight after starting T compared to before. It just increased my appetite somewhat in the beginning but it didn't cause a weight gain cause even though I was more hungry I resisted it and didn't actually eat more.
