Hello everyone. My name is Alex. I just started T 9 days ago (SOOOO EXCITED) and I came to the decision that I need to stop putting off dieting. I'm sick of being overweight (I'm 252lbs

, 5' 5", 20 years-old). I do like to run, which might be odd for someone in my weight group, but oh well. And when I say "run", I say that in the most flexible way possible. It's more like sprinting for 20 seconds, walk until I can catch my breath, then sprint again, which I'm told is healthier than the average pace.
Anyway, I guess there are a couple points to this post.
1. I'm TERRIBLE at dieting. I always get a great start going, and then I end up giving up sometime later, and I'm not sure why. It's almost impossible to convince myself that it's what I need, even though I yell at myself after. I'm going to join MyFitnessPal, and I wasn't sure how many here are currently on that or have tried it before.
2. While on T, I'm not really sure if I should be dieting in the more generally "female" way or the "male" way. That is to say, 1.) I don't know what a healthy weight would be for someone of my age and height, adding in the fact that I'm medically transitioning, so I'm not sure if 252lbs is still huge in male terms and 2.) I don't know if I should start lifting weight, while ALSO counting calories or cutting carbs from my diet, while ALSO adding more protein?? I'm just not sure on which side of the scale I should stand. On the one hand, my body is going to start reacting and developing similar to a biological male's, while on the other hand, I still have a biological female body for quite some time, so I'm not sure which "method" would work best for the most fat decrease and lean increase.

Sorry if that doesn't make much sense. I'm really terrible at wording things when I'm confused. Basically, I just want to know what a ftm can do to lose the most weight the fastest. I don't eat much (I have Hypothyroidism, my weight is not due to overeating), and I love to run, and I've noticed that already, the T is giving me much more energy to be able to work out much more efficiently at home, but I still have the female curves and body fat areas.
Thank you!!! Again, I'm reaaally sorry if it's confusing at all!! And it's really nice to meet everyone!

I'm so glad I can finally say I'm becoming who I really am! Woooooo!!
