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 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.

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 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.

If you're overweight and eat fewer carbs instead of less fat for four weeks, you might lose more body fat—even if you lose the same amount of total weight as someone on a low-fat diet.

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.
