Excess saturated fat could be bad depending on the health condition of the person.
This doesn’t match my reading of the literature. Even if someone had extensive CVD dietary fat wont increase their bad outcome risks. The damaged cholesterol (glycated and oxidate) is the warning sign of CVD issues - and that is caused by dietary sugar/carbs/industrial oils.
A diet high in saturated fat is more dangerous for the heart than a diet high in unsaturated fat, even when there has been no weight gain, according to new research funded by us and presented at the European Society of Cardiology Congress 2024 in London.
I haven’t seen it before, is this the paper they are hinting at (I HATE it when articles don’t mention the research they are talking about) https://doi.org/10.1242/dmm.050878 ?
The problem with this literature review is the studied studies only look at 30% total energy as LC, which on a 1500 kcal daily intake is 75g of carbs, which means the participants were not in a ketogenic state, not fat adapted, and had elevated insulin levels during the study. I think they looked at a weak signal across the data set, but that is the purpose of literature reviews.
I’m glad they are reviewing the Noakes literature. If you look at table 1, every low carbohydrate intervention regardless of fat composition resulted in a reduction of liver fat. That tells us saturated fat is not a independent variable in this review.
From the conclusion of the paper
Current evidence from hypercaloric feeding studies clearly shows that the consumption of excess calories,
regardless of the macronutrient composition, increases IHTG content.
hypercaloric and isocaloric intervention studies in humans is that an individual’s dietary fat composition likely plays a role in mediating their IHTG content and composition
Likely tells us this is a opinion, and they qualified it in the expert opinion even.
Although the effect of SFA on IHTG content appears to diverge from that of unsaturated FA, specifically PUFA, the mechanisms underpinning these observations remain to be elucidated
Likely because this analysis isn’t looking along insulin or ketogenic state. Probably because there is lots of paper competition, so taking a novel perspective has a better publication chance for a phd candidate.
It’s a interesting literature review, but hardly a smoking gun against saturated fat as a demon, especially when you look at table 1 and the ketogenic interventions.
If someone is worried about saturated fat content of their diet they can always do calcium imaging of their arteries - it’s inexpensive and gives a actual score of risk. As far as I’ve read in the literature serum cholesterol is not a danger, only if it’s damaged - which can be measured by several proxies (tg/hdl ratio, fasting insulin) or measured directly through diffusion (though that is expensive).
ok, yeah, agreed.

Please have a look at diet doctors literature review of saturated fat https://www.dietdoctor.com/low-carb/saturated-fat#evidence-to-date
It’s extremely well referenced.
Thanks. It is really good to know that I can be more relaxed with saturated fat in my diet. I’m already doing low carb.
Yeah, that’s great! I hope you see improvements.
