Is there any hope of a thicc gay guy to become skinny and more fem?

I'm pretty heavy (around 340) but I've been melting the wait off. The biggest I was being around 460 pounds. Is it still possible for me to get in shape and have a more fem figure or are my goals impossible? Like will I ever look normal even if I'm skinny or am I screwed? I just want to be attractive...and I'm afraid it may not happen.
