Low-carb diets may help prevent or improve serious health conditions, such as metabolic syndrome, diabetes, high blood pressure and cardiovascular disease. In fact, almost any diet that helps you shed excess weight can reduce or even reverse risk factors for cardiovascular disease and diabetes. Most weight-loss diets — not just low-carb diets — may improve blood cholesterol or blood sugar levels, at least temporarily.
While eating a low-carbohydrate diet might not be the “magic bullet” to lasting weight loss for every person, it’s very helpful for most people to cut back on added sources of sugar and processed carbs. Removing foods such as bread, cereals, sweetened drinks, processed dairy and in some cases, even whole grains or starchy veggies from your diet can result in your body releasing less insulin.
