Which combined lifestyle strategy is most likely to produce clinically meaningful reductions in hypertension risk for an overweight adult who currently consumes a typical high‑sodium American diet?

• A. Adopt the DASH diet (lower sodium, higher fruits/vegetables/low‑fat dairy), reduce body weight by 5–10%, and increase regular aerobic physical activity — a multifactorial approach has additive benefits for blood pressure reduction.
• B. Only reduce dietary sodium while keeping body weight and activity constant because sodium reduction alone will reliably normalize blood pressure in most overweight adults without other changes.
• C. Focus exclusively on moderate alcohol consumption, because alcohol restriction produces larger blood pressure falls than diet alteration, weight loss, or physical activity combined in population studies.
• D. Begin high‑dose mineral supplementation of calcium and magnesium without any dietary changes, since supplements alone fully counteract the hypertensive effects of high sodium intake regardless of body weight.
