some experts have suggested out that low carbohydrate diets (LCD) are more effective for weight loss and glycemic control. However, long term results are controversial.
to review and analyze randomized control studies that evaluate the effect of LCD on weight and metabolic control in individuals with type 2 diabetes for a period equal to or greater than 10 months.
a systematic review was conducted on randomized trials registered in PubMed, EBSCOhost and Scielo to May 15th 2015, published in English and Spanish, with the following search data: "diabetes mellitus" AND "carbohydrate restricted diet" OR "restricted carbohydrate diet" OR "low carbohydrate diet" AND "weight loss".
four studies met the inclusion criteria. There were 444 participants between 18-70yo. Follow-up time ranged between 10 to 24 months. Three out of the four studies reported weight reduction with LCD. However, when LCD were compared with other diets no significant differences in weight loss or A1C levels were observed.
this review showed that three of four studies on the LCD were effective for weight loss over a period of 10 to 24 months. However, there was no evidence showing better results than those observed with other diets. Nor, difference in A1C.
一些专家指出，低碳水化合物饮食（LCD）对减肥和血糖控制更有效。然而，长期效果存在争议。
回顾和分析随机对照研究，这些研究评估了LCD对2型糖尿病患者体重和代谢控制的影响，为期等于或大于10个月。
对截至2015年5月15日在PubMed、EBSCOhost和Scielo上注册的随机试验进行系统评价，这些试验以英文和西班牙文发表，搜索数据如下：“糖尿病”与“碳水化合物限制饮食”或“限制碳水化合物饮食”或“低碳水化合物饮食”以及“减肥”。
四项研究符合纳入标准。有444名年龄在18至70岁之间的参与者。随访时间为10至24个月。四项研究中有三项报告LCD可减轻体重。然而，当将LCD与其他饮食进行比较时，未观察到体重减轻或糖化血红蛋白（A1C）水平有显著差异。
本综述表明，四项关于LCD的研究中有三项在10至24个月内对减肥有效。然而，没有证据表明其效果优于其他饮食。糖化血红蛋白方面也无差异。
