Got a lot to do with humans' "reptile brain".
Back in the day when we were living in caves and poking each other in the eye with a burnt stick, food was hard to come by, heating was a bit hit-and-miss and clothing was not as stylish as today (although I wonder).
Humankind needed fat to survive and the eating of fatty foods (i.e. animal fat) was an essential to survival. In much the same way as the desire to procreate, this has become a innate desire, but unfortunately, the high metabolism rate which was a trait of the hunter-gatherer has not kept pace.
I'm very lucky, I have a fast metabolism and no matter what I eat, I don't put on weight. Oh, I've got the middle-age spread, but I weigh 90 kgs or so, much as I always have and these days, my most strenuous exercise is getting out of bed.
Life's a lottery - and I was lucky enough to get a winning ticket. (these cigarettes are going to kill me, though)
