Losing Weight May Improve Your Blood Pressure

Published:August 26th, 2011

Are you overweight and hypertensive at the same time? Does your doctor tell you to reduce your weight in order to reap the benefits of blood pressure reduction? Do you ever wonder why you have to reduce your weight in order to control your blood pressure better? Well, wonder no more.

In a study conducted by a group of researchers from Baker IDI Heart & Diabetes Institute, Melbourne, Victoria, Australia and published in the August 2011 issue of the journal Hypertension Research, the researchers discovered that blood pressure reduction can be achieved with calorie-restricted diet and exercise that induce weight loss.

In this particular study, the researchers investigated the effect of a calorie restricted diet alone, exercise alone and calorie-restricted alone plus exercise to induce weight loss and control the blood pressure in 30 obese men with problems with their blood pressure reading. The researchers divided their subjects into three classes and imposed these weight-loss methods to them for over 24 weeks.Their body mass index,  blood pressure, waist-to-hip ratio, plasma norepinephrine and insulin resistance were measured every 2 weeks for the first 4 weeks and every four weeks thereafter to monitor their body parameter changes and their blood pressure improvements.

The researchers noted that those obese men who were assigned to the calorie-restricted diet plus exercise reaped the greatest benefit in weight reduction and blood pressure control compared to those had a calorie-restricted diet alone and those who had exercise alone. Thus, the researchers concluded that a calorie-restricted diet plus exercise is the best lifestyle modification to those patients suffering from overweight or obesity and hypertension. However, further clinical investigation is still needed to further establish this fact.
