On “Being fatter than Homer Simpson”

I don't think there's any evidence that they're inflammatory (great video about it here 1), but obviously oils are almost 100% fat and therefore have a ton of calories. At the same time, some people feel incredibly satiated from eating fats, to the point where they might eat fewer total calories if they include some... Generally, avoiding added high calorie fillers (that includes sugar and oils alike) is almost certainly a good idea if you're trying to lose weight though. 1 link to this video

On “Saturated fat: the making and unmaking of a scientific consensus (2022)”

Except the human studies we have suggest that seed oils are probably not inflammatory. A few examples are listed in this video: link to this video

Are there any human randomised control trials that show stuff like vegetable oil cause inflammation? Atleast the ones I've seen show the opposite link to this video
