Low-carbohydrate diet not only helps to lose weight, but also may have other aspects of the health benefits. New research shows that the role of low-carbohydrate diet and weight-loss drug orlistat, like him, can help overweight and obese people lose weight, not only so, insist on low-carbohydrate eating habits of people's blood pressure also dropped to health.
Participate in the study at Duke University Medical Center, William S. Yancy, associate professor, said: "I originally estimated that the two therapies, body weight will be substantially reduced, but we are surprised to find that, through the low-carbohydrate diet to improve the effect of blood pressure, even More than the use of weight-loss drug orlistat. If people have high blood pressure and obesity, low-carbohydrate diet should be a better choice than diet pills. "
The researchers said previous studies showed that these two kinds of weight loss methods have helped to lose weight, while the latest study is the first time they have a direct comparison of the two methods. Yancey said: "The important thing is that we can achieve the same diet to lose weight rather than the drug effect, while investing less, with fewer side effects."
The release of the "Internal Medicine" magazine on the latest study, researchers will be 146 obese or overweight adults, randomly divided into two groups. Among the participants in these studies, many people have chronic health problems, such as hypertension or diabetes. The researchers suggested that the first group of maintaining low-carbohydrate ketogenic diet, carbohydrate intake per day less than 20 grams, the second group Chijianfeiyao orlistat, three times a day, in addition to the panel meeting, acceptance of the low-fat diet (fat intake of calories per day less than 30%) guidance. The results show that the same effect as the two teams to lose weight, adhere to a low carbohydrate diet group reduced by an average weight of 9.5%, while the Chijianfeiyao weight orlistat group reduced by an average 8.5%. The two weight loss methods to improve cholesterol and blood sugar levels and no much difference.
However, when the researchers analyzed changes in blood pressure of participants, they found that adhering to a low-carbohydrate diet group, nearly half of the blood pressure medicine during the study period reduced or interrupted, compared to eating orlistat group was only 21%.
Overall, in the low-carbohydrate diet group, systolic blood pressure an average of 5.9%, compared to taking orlistat group systolic blood pressure increased by 1.5%. The researchers said that, under normal circumstances, losing weight itself will lower blood pressure to healthy levels, but there are other low-carbohydrate diet appeared blood pressure effects, it still needs further study.
