Carnivore diet myths: saturated fat, fiber, and LDL
About a third of people who start carnivore see their LDL cholesterol rise, yet markers like fasting insulin, triglycerides, and hs-CRP staying in normal range matter more for heart risk than that single number, and fiber turns out to be unnecessary since a meal of meat and eggs is fully digested within about two hours.
- What to do: Cover vitamin gaps with two to four ounces of liver a week, or a liver supplement, and track A1C, fasting insulin, triglycerides, HDL, and hs-CRP alongside LDL instead of watching LDL alone.
- Why it matters: The clogged-artery fear comes from a decades-old ad campaign, not physiology, since arteries sit at body temperature and dietary fat never solidifies inside them, and pre-diabetes, obesity, and smoking carry more established heart risk than elevated LDL.
- How to apply it: Treat carnivore as a genuine elimination diet by removing seed oils, grains, and legumes, keep the rendered fat instead of pouring it out, and mix it with a zero-sugar condiment like mustard.
- Metrics: Roughly a third of people see LDL drop, a third stay the same, a third rise, and about 1% spike sharply; meat clears the stomach in around two hours.
- Tools: An organ-based seasoning blend with beef liver and garlic adds about half an ounce of liver to a meal without changing the taste.
- Exceptions: People managing severe autoimmune or inflammatory conditions may skip spices and seasonings for the first 90 to 180 days to rule out triggers.
