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 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 very few carbs—like on a strict keto diet—can raise your 'bad' cholesterol, especially if you're replacing those carbs with lots of saturated fats like butter and red meat.

If you're overweight and have high 'bad' cholesterol, eating fewer carbs for four weeks might help lower your bad cholesterol and improve your overall cholesterol balance better than eating low-fat, high-carb foods.

Eating fewer carbs might help people with type 2 diabetes who are overweight lose around 8 pounds and improve how their body uses insulin over several months.
