People on a meat-only diet for up to a few years tend to see their 'bad' and total cholesterol go up a lot, which might raise their risk of heart problems.

People on a meat-only diet for a month or more tend to see their bad and total cholesterol go up a lot, which could raise their risk of heart disease.

People in Germany who ate only meat for about a year saw their bad cholesterol and overall cholesterol go up a lot, according to one small study.

If adults eat only meat for a month or more, their bad and total cholesterol levels go up a lot — so much that about half end up with LDL cholesterol above the healthy range.

People eating only meat had very high 'bad' cholesterol but also high 'good' cholesterol and very low triglycerides — a pattern that usually means their bodies handle sugar well.

People who are overweight and eat a low-carb diet end up eating more cholesterol over time—way more than the old health guidelines recommended—but their bad and good cholesterol levels, and triglycerides, didn’t get worse. This suggests that eating more cholesterol might not hurt your heart like we used to think.
