Eating fewer carbs might help people with type 2 diabetes who are overweight or obese improve their cholesterol numbers — lowering bad fats in the blood and raising good cholesterol — which could mean a healthier heart over time.

If you're an adult with obesity and you eat fewer carbs on a low-carb diet, you might lose more weight and see better cholesterol numbers in just a few months.

Eating fewer carbs doesn’t really change bad or total cholesterol levels in adults with type 2 diabetes who are overweight or obese — it might help other things, but not these cholesterol numbers.

Eating fewer carbs might help boost good cholesterol and lower blood fats in people with higher body weight, but it doesn’t seem to change overall or bad cholesterol much.

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.
