Summary
On episode 573 of 40+ Fitness, Coach Allan sits down with Ivor Cummins, known as the Fat Emperor, an engineer turned health science investigator who spent years dissecting the science behind low fat diets and found it was built on shaky ground.
Ivor explains why food and health science rarely behaves like real science: unlike physics or math, food and pharma are two of the biggest markets on the planet, so funding and ideology shape the studies and the headlines that come from them.
The conversation covers how to spot a weak study through funding and ideology, why correlation keeps getting mistaken for causation, why whole animal based foods match human evolution and nutrient needs, and the three things Ivor prioritizes to protect his own heart health.

Key Takeaways
- Food and health science gets co-opted by money in a way physics doesn't. Ivor argues theoretical sciences stayed close to the scientific method because there's no mass market forcing conclusions, while food and pharma are massive industries with a direct interest in the outcome of research.
- Check funding and ideology before trusting a study. If a conclusion lines up neatly with veganism, a particular university, climate politics, or an industry sponsor, look up who paid for it and who wrote it before accepting the headline.
- Correlation keeps getting sold as causation. Ivor's example: decades of “healthy user bias” made vegetable oil look good in the data, not because the oil helped, but because health conscious people were the ones following the official advice to eat more of it.
- Whole animal based foods best match human evolution. Ivor points to paleoanthropology, nutrient density, and nutrients like B12 that only occur in animal foods as evidence that meat, fish, and eggs are hard to beat nutritionally, though whole plant foods aren't the enemy either.
- The WHO's “meat causes cancer” claim rested on weak associational data. Ivor calls the 2015 classification of processed meat as a carcinogen absurd, built mostly from correlational studies rather than proof.
- Ancel Keys' seven country study cherry picked its data. Keys selected the countries most likely to support his hypothesis out of roughly 22 available, and that choice shaped decades of official advice against saturated fat.
- Insulin resistance drives most heart disease. Citing Dr. Joseph Kraft's five hour glucose testing and the Euro Aspire study across 24 countries, Ivor says roughly three quarters of heart disease patients were diabetic or pre-diabetic, most of them undiagnosed.
- A coronary calcium scan beats standard risk factors at predicting heart attacks. A score of zero carries an extremely low risk of a cardiac event, while a high score, like the one that led David Bobbett to make the film The Widowmaker, can mean 20 times the risk even with normal cholesterol.
- Ivor's three strategies to get and stay well: cut the “devil's triad” of sugar, refined carbs, and seed oils in favor of real food; do resistance and bodyweight training to failure a few times a week; and prioritize sleep quality and stress management.
“There are a thousand studies now, all driven by ideology, whether climate, religious, or just general dietary ideologies.”
