studies show obesity reduces your lifespan by 9 months.

So your choice is to eat what you want your whole life and live 9 months less when it doesn't matter anymore... or live your life in misery eating rice cakes.

I'll eat what I want in moderation, and if it shaves a few months off my life... then so be it.

studies show obesity reduces your lifespan by 9 months

Obviously it depends on how obese you are and at what age, but even a very brief search shows that studies actually show a much bigger effect than the one you state.
