Weight limits and any way to help it (other then losing weight)

I wanna start by saying I am working out and dieting to lose weight I am currently 297-300lbs and I’m trying to get a discovery flight I have potential to have a va loan but if I don’t use it within a couple months it won’t be possible for me to use it. And everywhere around the Columbus In area seems to have a weight limit of 250-240 lbs in order to fly a discovery flight
I’m trying as hard as I can to prove that I can and will finish the course but I want to take this step to show I can do it
