According to a study published in the Archives of Internal Medicine, January 25, 2010, a low-carb diet can have a significant effect on high blood pressure. Previous studies have shown that reducing carbohydrate intake provides faster weight loss and improved cholesterol, despite the common assumption that the low-carb diet must be unhealthy.
據一項於2010年1月25日在內科醫學檔案發表的研究，低碳水化合物飲食能對血壓高產生顯著的影響。先前的研究已顯示，減少碳水化合物攝取量提供較快的減磅和改善膽固醇，儘管一般的假設低碳水化合物飲食一定是不健康的。

低碳水化合物研究的詳情
Low-carb study details
The Jan 2010 study compared weight loss, cholesterol changes, and blood pressure changes in 146 obese patients over the course of 48 weeks. The patients were placed in two groups for the study. One group received education and weight-loss support for a low-carb diet, and the other received education and support for a low-fat, low-calorie diet supplemented by the weight-loss pill orlistat (Also known as Alli or Xenical).
In this study, the low-carb group lost slightly more weight than the diet-pill group. (Low-carbers lost an average of 9.5% of their starting body weight, diet-pill group lost an average of 8.5% of their body weight during the study).

High blood pressure effects
Over the course of the study, the patients on the low-carb plan experienced a drop in blood pressure readings. Systolic blood pressure was reduced by an average of 6 points, and diastolic blood pressure lowered by an average of 4.5 points. The patients taking Alli/Xeneca diet pills increased their blood pressure by an average of 1.5 mm HG (systolic) and .4 mm HG (diastolic).

較早前低碳水化合物的研究
Earlier low-carb study
Dr. William Yancy, the lead researcher in this low-carb study, conducted another study on the effects of lower-carbohydrate dieting vs. other types of diets in 2004, while at Duke University Medical Center. That study concluded that low-carb diets resulted in more weight loss, as well as a significant improvement in cholesterol.
