Your biases seem to be driving your views more than your supposed rationality, at least on this issue.
There are plenty of obvious reasons people likely to die young would end up alone. It's natural to not be attracted to people likely to die young, it's a behavior our evolution has selected for.
We're not attracted to sick-looking people, for example.
That's cool if you set your standards extraordinarily high and you can't find someone because of it, but don't blame evolution, realize you set those standards.
I'm pointing out obvious reasons people who die prematurely would also be alone, pointing out obvious flaws with the article's unscientific claims.
People who are sick are less attractive to the opposite sex, this is a deeply-rooted evolutionary trait. I'm saying this in reference to one of many obvious reasons people destined to die early also are alone. Few want to date or live with seriously ill people. They're arguably not dying young because they're alone, they're alone because they're sick and likely to die young.
I made no such claim that evolution explains my personal choices on this topic as it pertains to my life, no sir, I proudly own those 100%.
My argument is that "evolutionary attraction" isn't actually a phenomena. Our interests have swung wildly from valuing huge to tiny and from pale to tan all due to cultural shifts, not because of an innate inbuilt evolutionary mechanism - there was no filtering of genes due to these features. Heroin chic was a thing, and that's downright sickly.
Statistically speaking, 75%+ of the adults in the US are overweight. That is the pool being drawn from.
So when you're not in the overweight majority, and have no interest in cohabitating with an overweight person who presumably lives a lifestyle contributing to being overweight, you already have just 25% or less of the population to pick from.
Now you need to find within that fraction someone you actually like as a person, who doesn't have any of the other unhealthy habits unrelated to being overweight you want nothing to do with.
