In the modern world: Yes.
A long long time ago: It was a good thing. Being fat meant you could survive longer without eating.
Once again, in the modern, developed, world where food shortage isn't a problem, it may not always be the "best". However, it is the most concentrated, and a long time ago eating fat was the evolutionary advantage.
I'm trying to say that humans naturally like the taste of fat better because we evolved to.
You're stupid. How the hell would you know anything about being fat long ago? For a fact, when humans don't eat, their bodies make an attempt to store as much fat as they can, and only use the fat to sustain at the verge of starvation. In healthy bodies, there's not much fat to use when there's no other food.
Long ago, people weren't fat because their daily lives required near constant physical strain, and they ate about half of what we eat by standard. They had to walk anywhere if they didn't have a wagon, and nearly everything was done by hand. I assume you're talking about times before industrialism, electricity, cars, etc...
We don't evolve like the taste of butter, you forgettard. "liking the taste" or something varies from person to person, and I know we have always accepted the taste of fat as something awesome, it's why people used to put butter on everything. Of course that was before they were eating so much food.
Did you know 50-60 years ago an 8 oz beverage at a fast food joint was a large? Yeah.
