Mark Ennis and Victoria Olson dive straight into one of the most controversial questions in modern nutrition: what if the very oils we were told would “protect our hearts” are actually driving metabolic dysfunction?

In this conversation, Mark and Victoria break down how industrial seed and vegetable oils – high in unstable polyunsaturated fats – become prone to oxidation, disrupt cell membrane structure, and interfere with cellular signaling. The result? What they describe is “metabolic chaos.”

They also tackle the cholesterol question head-on. Rather than viewing cholesterol as the villain, they discuss its structural and reparative role in cell membranes – and how excessive intake of processed seed oils displaces and undermines cholesterol’s protective functions. If cholesterol is the stabilizer and repair molecule, what happens when it’s crowded out by fragile, easily oxidized fats?

Finally, they zoom out to the last 50 years of dietary guidance – low-fat messaging, vegetable oil promotion, and the parallel rise in obesity, diabetes, and arterial disease – and ask whether we’ve misunderstood the root cause of the epidemic.

Victoria also shares insights from her soon-to-be-published book, “Troubleshooting Your Carnivore Diet,” offering practical strategies for those using a carnivore framework to restore metabolic health and reduce inflammatory burden.

If you’re curious about the biochemical case against seed oils – and the argument for rethinking long-standing nutrition dogma – this discussion will challenge you to look deeper.
