Energy balance

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.
