That seems like an extremely far-reaching statement. Are you sure you wish to hold to it?
It isn’t a select few being given the option, anyone could take up the same option if they want and need to.
If they have no desire to change their body by losing weight then obviously they would have to come to terms with who they are. Equally, plenty of people with various forms of gender identity issues don’t choose to take any medical intervention, maybe even not making significant changes to their natural appearance as they’ve come to terms with who they are.
Others wish to go a different way and that is their choice. An overweight person, especially one who is overweight due to genetic or medical conditions can and should get support in losing weight, up to and including surgical options available where appropriate for their individual circumstances. A person with gender identity issues should similarly have support available and may seek surgical options as appropriate to them.
Really? Have you had a haircut recently?
