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?

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.

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.

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.

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.
