If you swap out carbs in your diet for healthy fats or protein, your body may make more of a good cholesterol protein that helps protect your heart, but less of another protein linked to heart disease risk — and this happens within just four weeks if you have slightly high blood pressure.

If you swap out 10% of the carbs in your diet (like bread or sugar) for healthier fats (like olive oil or nuts), your body might produce a little more of a good protein in your blood that helps protect your heart — and this change can happen in just four weeks if you have slightly high blood pressure.

If you swap out 10% of the carbs in your diet for more protein, it might lower certain proteins in your 'good cholesterol' that are linked to heart disease — and this change happens in people with slightly high blood pressure after just 4 weeks.
