Adherence to a composite low-risk lifestyle profile (non-smoking, BMI <25, moderate alcohol, vigorous exercise, and specific dietary metrics) reduces the relative risk of major coronary events to 0.17 compared to non-adherent women.

To drastically lower your risk of heart disease, focus on a combination of habits rather than a single magic bullet. Stop smoking, keep your weight under a BMI of 25, engage in at least 30 minutes of brisk walking or similar activity daily, and consume moderate amounts of alcohol (if you drink). Crucially, prioritize a diet high in fiber, healthy fats, and folate while minimizing trans fats and high-glycemic foods. Even if you can't hit every target perfectly, moving in this direction significantly reduces risk.
