Most blood test results stay normal when adults go on a carnivore diet, and fewer results fall outside the healthy range after starting the diet — though the change isn't big enough to be sure it's not just by chance.

People on a meat-only diet saw fewer blood test results outside the normal range over time — it didn’t reach statistical proof, but there’s a hint their metabolism may be getting more in line with healthy levels.

People with diabetes who ate only meat lost weight and lowered their blood sugar enough that most stopped taking their diabetes pills or insulin.
