Surprising Findings
Despite massive cholesterol increases, more people had normal blood markers on the diet than before.
We expect high cholesterol to mean worse overall health, but 24.4% of pre-diet markers were abnormal vs. 18.3% on-diet — suggesting possible metabolic benefits in some.
Practical Takeaways
If you're considering a carnivore diet, get blood work before and after to monitor cholesterol and metabolic markers.

Eating only animal products might help calm inflammation in your body by lowering high triglycerides, which could mean your metabolism is under less stress.
Burning fat for fuel helps keep your energy steady and your blood sugar from spiking and crashing, unlike when your body runs on carbs.
Eating only animal products might help people with slightly high blood sugar get it under better control, based on lower HbA1c levels seen in some people.
Most people in a small group of German meat-eaters started the carnivore diet because they had health problems, and they kept it up because they felt healthier — suggesting this diet tends to attract people who already have medical issues.
