imagine thinking it's ok to be fat
While I would agree that being overweight generally can cause issues is there really anything inherently wrong with it? I've known plenty of people who were less-than-fit, but were entirely ok with that and it had little impact on their general happiness. Most of them were perfectly fine with the risks associated with their lifestyle, and a few are already dead from it, but I find it hard to argue that they didn't enjoy their lives.
With regards on the medical side of things, I'd say being morbidly obese is where it starts to get serious. Other than that, I've seen plenty of fat people live a long time with little issues (but not as much as fit people). What does confuse me, is why people are more concerned about the cancer risks that come with it, rather than CHF. According to the CDC, at least 90% of CHF cases are preventable through excercise and treatment, while cancer (mathematically speaking) is unpreventable a majority of the time. I'm not an expert on this, but from when I've spoken to oncologists, cancers are naturally inevitable simply by being alive.
To be clear, I'm not trying to downplay cancer, as I've seen it plenty of times in person and it is god fucking awful, but I don't think enough funding and attention is going into other areas.
