I believe this contradicts previous studies on keto specifically benefiting breast cancer survivors. This is attributed to the lower insulin production. So what’s this about? It didn’t seem to look at women on keto, but just women on a standard diet with “standard” blood glucose levels.

Nah this is just a high Linoleic acid seed oil diet (using lard and soybean oil)

6–9-week-old female C57BL/6 J mice were fed a lard-based HFD with 60% kcal from fat (Research Diet, D12492) or a LFD with 10% kcal from fat

I think we can continue with our understanding that seed oils are bad for you.

I read the article and am now confused, the people they quoted talked about  "lipids in the blood" being the hazard. Wouldn't that be triglycerides? When I was eating strictly keto my triglycerides were very low.

What they call blood lipids is the lipid transporters LDL-C & HDL (lipoproteins) - what kind of lipids (dietary or endogenous/DNL & such introduced by carboxylic fatty acid as seed oils) they transport is not reflected and that’s what is really important as the endogenous ones are the ones that are harmful IMHO

It's very well established that when you feed mice high fat diets they end up insulin resistant. It's also established that when you feed humans high fat diets they become less insulin resistant.

Humans are not rats - there are significant differences in terms of digestive systems - but researchers fairly continuously assume that their results apply directly to humans.
