Well first off you took one section of a collective, which are all intertwined, not to mention the articles, one of which explains Trump is now eating healthier.
Secondly, by asking how unhealthy can it be, I'm clearly implying it's unhealthy, but how destructive is it exactly is the underlying point. Which would mean it's unhealthy to some degree, but whether it's slightly unhealthy, or horrendously unhealthy, is the question.
Thirdly, as this is part of what was said prior, these stars do not necessarily want to promote the product itself, or care about the product at all. If people choose to stuff their faces and sit on their butts all day, it's their fault for what follows. You shouldn't eat lot's of fast food if you can't burn it off, whether that's natural or through exercise, just like how you shouldn't go out and purchase a bunch of luxury items through credit if you don't plan to pay them off, naturally or though extra work.
