Low libido age 27? What is causing it?

Hi, I was wondering if something in my lifestyle is affecting my sex drive. I quit vaping like 6 months ago, but mostly replaced it with smoking a fair amount of weed. I don't eat all that healthy, but in general it seem like my sex drive is just lower than it used to be. I also mostly stopped exercising. What should I do that will fix this the most?
