I think the trouble is define 'high fat diet' What kind of fats are we talking about exactly. Trans-fats? Rancid fats. Fats in cured meat? Fats from seed oils? What kind of seeds? Vegetable fats? If so again what kind? Maybe you think olive oil is okay. What if I told you 90% of olive oil is adulterated? Animal fat? What's that animal been eating? The last one is interesting. Before WWII frozen chicken really wasn't a thing because frozen chicken tasted rancid after it was thawed. Someone figured out you could fix that by switching the feed from linseed to corn.
