Correlation != causation. Let me guess the root cause of this "fat is evil" meme. People who love fat are often gluttons. They eat what they want, in large quantities, and don't care about the consequences. They also consume huge quantities of processed sugar, which is now found to be "bad", and don't eat their greens. Health freaks avoid fats and sugar, living on lean meat, veggies, and grains. This may not be optimal, but it's better than Big Macs, Cola, and fries.
