Weight loss of 3-10% of baseline body weight reduces systolic and diastolic blood pressure by approximately 3 mmHg, independent of salt restriction, primarily through decreased sympathetic nervous system activity and improved insulin sensitivity.
If you have high blood pressure and are overweight, aim to lose just 3-10% of your current body weight. You do not need to reach a 'perfect' weight to see benefits; this modest loss can lower blood pressure by about 3 mmHg. Work with a dietitian to achieve this gradually using calorie reduction and behavioral strategies like appetite awareness, rather than crash dieting.
Weight reducing diets in overweight people with hypertension, leading to a modest weight loss (3–10% of baseline body weight), decreased/discontinued dosage requirements of antihypertensive medications and reduced SBP and DBP by ~3 mmHg resulting in lower BP levels even without reaching ideal weight [40]. ... The BP-lowering effect of weight loss is most likely a result of a decrease in sympathetic nervous system activity and an improvement in insulin sensitivity [42] and occurs independent of salt restriction.

- Regular physical activity, including aerobic, dynamic resistance, and isometric training, reduces blood pressure, with isometric training showing significant reductions when performed at ~30% of maximal voluntary contraction.Good
- Adoption of the DASH diet or similar healthy dietary patterns (high in fruits, vegetables, low-fat dairy, low in saturated fat/salt) reduces blood pressure and is recommended as a first-line intervention for hypertension management.Good
