Induction of hypertriglyceridemia by a low-fat diet.

Cross-Sectional Study

Human

1976 Apr

The study gave 27 people a diet with less fat and more carbs, and 26 of them ended up with higher triglyceride levels — just like the claim said. So the study backs up the claim perfectly.

Similar Assertions

When you swap fats (like butter or oil) for carbs (like bread or sugar), your blood fat levels (triglycerides) tend to go up.

Eating a diet low in fat and high in carbs makes the body less able to clear fat from the blood, causing triglyceride levels to rise sharply.

When people eat less fat and more carbs, their blood fat levels (triglycerides) go up a lot—even if their cholesterol stays the same—and high blood fat is linked to heart disease.

After eating, people on a low-fat, high-carb diet have higher levels of fat, sugar, and insulin in their blood for longer than when they eat a diet with more fat, which might stress the body over time.

When overweight mice eat fewer calories, only those on a low-carb, high-fat diet see a big drop in blood fats called triglycerides — other diets don’t have the same effect.
