There is no reason to avoid fat.

Here is one instance of an easily accessible peer-reviewed-science-based list of the current knowledge on dietary fat: https://www.foundmyfitness.com/news/t/fat

It does not show that oils or fat are something to blanket avoid.

I didn't say to avoid fat, I said to avoid extracted fats (oils). Whole food fats e.g. the olive instead of olive oil is fine

About a year ago, I started looking into current nutritional advice. One thing that stood out was that the average American used to get 40% of their calories from fat and 1/6 of Americans were obese. The government recommended reducing fat to less than 30% of overall calories, and, amazingly, Americans actually followed the recommendation. We now get about 30% of our calories from fat, and 1/3 of us are obese.

That doesn’t say much about what kind of fat we’re eating (e.g., if it’s oil), but the advice to reduce calories from fat was based on them being empty calories. It appears that they also help people feel full longer.

Personally, when I eat a salad for lunch, it doesn’t bother me that literally 85% of the calories come from fat (15 calories for the lettuce, 90 calories for the salad dressing). Even if I have low-fat salad dressing (30 calories), I’m getting 66% of my calories from fat.

Then again , maybe I’m reading the data wrong: it’s possible to reduce the percentage of calories coming from fat by eating the same amount of fat, and more food overall. Maybe Americans just did that.

Olives make a good snack, olive oil doesn't. Olive oil is great for frying things in, whole (or even sliced) olives aren't.

It's silly to pretend that you can pick one and live your life without the other. Or that there is never a need for some sort of cooking fat.

Because you're assuming maintaining the same eating habits. I have literally consumed no overt oils for a year now, have had no need for a cooking fat, and have had no lack in creative dishes. I eat flavorful curries, soups, etc. If I want something similar to sauted, I can use water or broth. If I want something crispy, I can bake. You just lack creative imagination to see that it's possible.

As dietary advice is being presented here as explicit statements (incidentally without evidence) I want to make this claim: The advice to avoid extracted fats (oils) is not sound.

As categories, oils and fat are fine. They both contain elements which are good for health. There are subcategories which seem to be bad for health (e.g. trans fats, and oils with those in, or rancid oil).

There's no physiological need for oil. Fat, yes. Oil is purely culinary.
