Good news!
Keto zealots have gone through various stages of KETO-CTA grief and have finally reached acceptance of the fact that no cardiovascular outcome RCT exists for keto.
Classic motte-and-bailey alert.
What is a keto clown to do when the circus collapses? Easy. Demand that the other side prove a standard no medical intervention has ever met. Directly randomize humans to high versus low ApoB for decades, withhold proven therapy from the control group, and measure what happens.
That experiment cannot be done. It would be unethical.
By that same standard, smoking does not cause lung cancer. No one randomized people to smoke for forty years.
Seatbelts do not save lives. No one randomized drivers to go beltless at highway speed.
Blood pressure treatment is unproven. Withholding antihypertensives from a control group for a decade would be monstrous.
The keto RCT has no such barrier. Food trials are not unethical. PREDIMED randomized 7,447 people to a dietary pattern. DiRECT randomized adults to a low-calorie dietary intervention and measured hard metabolic outcomes.
Randomizing someone to eat differently for two years has no ethics problem.
The carnivore / keto community even raised $216,880 for exactly this trial. The money materialized. The trial vaporized.
So instead we use the best available evidence. For ApoB that is 170,000 patients across statin trials, 27,564 in FOURIER, 18,144 in IMPROVE-IT with an ezetimibe mechanism that has nothing to do with statins, and a natural experiment running in PCSK9 loss-of-function carriers for generations showing 88% lower coronary heart disease.
For keto: no cardiovascular outcome trial, no loss-of-function genetics showing lifelong keto-adapted humans with lower coronary heart disease, no Mendelian randomization, no dose-response line, no natural experiment of any kind, and no proposed causal mechanism from dietary ketosis to reduced cardiovascular events that does not run directly through ApoB particle burden.
If their mechanism runs through ApoB, they have conceded the argument. If it does not, they need to name it.
Their circus collapsed. Their response is to set fire to the building and call it a draw.
Stay awake my friends.
There’s isn’t one but then again there isn’t a single one for your beloved ApoB either, life’s a b$tch isn’t it
