Multicomponent lifestyle interventions (dietary changes, weight loss, and increased physical activity) significantly reduce estimated 10-year coronary heart disease (CHD) risk in adults with prehypertension or stage 1 hypertension.
If you have high-normal blood pressure, making specific changes to your diet (like the DASH diet), increasing physical activity, and losing weight can significantly lower your estimated risk of heart disease over the next 10 years. You don't need to do everything perfectly; even partial adherence to these lifestyle changes can lead to substantial health benefits.
In individuals with prehypertension or stage 1 hypertension, 2 multicomponent behavioral interventions, EST+DASH and EST, significantly reduced the estimated 10-year CHD risk by 12% and 14%, respectively, compared with advice only.
Why this rating
Randomized controlled trial with a large sample size (n=810) and statistically significant results, though it uses estimated risk rather than hard clinical outcomes.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
