In many circles, if I were to say that I wanted to be more fit in order to attract the kinds of people I'm attracted to, the main answer I would get is that I shouldn't feel the need to change anything about myself - that someone who would be more attracted to me if I were to work on myself isn't worth the effort. I heard this from my sibling-in-law constantly. Honestly started to think they were just trying to justify their own disregard of their health.
I started a 430 lb 6'4 man. I'm 320 lb now and while I still have a ways to go, the difference in the attention I get is mind boggling. Women actually flirt with me now. Initiate even. As someone who's felt invisible for a decade, I can't describe how much my mental state has improved.
