研究目的:

主要目的:观察限制热量低碳水化合物饮食及限制热量正常结构饮食两组方案对超重/肥胖受试者在减重效果、糖脂代谢、血管内皮功能等的变化。 次要目的:在超重或肥胖的受试者中,比较热量限制和低碳水化合物饮食在减重疗效及代谢改善上的优劣。因此2016年的AACE指南指出对于超重、肥胖的患者,制定结构化的生活方式干预计划,包括科学合理的饮食计划、体育运动与行为干预至关重要。而饮食干预是减重生活方式干预中最关键的环节。  

Objectives of Study:

The usefulness of low-carbohydrate diet for Chinese overweight or obesity subjects with type 2 diabetes mellitus or prediabetes has not been fully investigated. Therefore, we compared the effectiveness and safety of calorie-restricted low-carbohydrate diet with calorie-restricted balance diet.

药物成份或治疗方案详述:

本试验为前瞻性随机对照试验,随机分为常规治疗+低能量均衡饮食组(对照组)和常规治疗+低能量低碳膳食干预组(治疗组)。每组60人。干预组对象在减重期将接受低碳水化合物饮食的面对面具体指导。膳食蛋白质供能比40-50%,脂肪供能比30-35%,碳水化合物供能比20-25%,限制每日总能量的摄入为1000-1200kcal。为达到低碳水化合物的膳食要求,每日午晚餐主食由研究组提供的营养代餐棒代替。对照组对象接受标准的减重膳食建议及总能量控制基础上的平衡膳食,建议能量摄入每天减少300-500kcal,严格限制食用油和脂肪的摄入,适量控制精制白米面和肉类,保证蔬菜水果和牛奶的摄入充足,三大营养素供能比为脂肪20-25%,蛋白质15-20%,碳水化合物55-65%,给予示范食谱及饮食注意事项。分别在干预的第2、4、8周随访。 

Description for medicine or protocol of treatment in detail:

Participants: 120 subjects with type 2 diabetes mellitus or prediabetes at the enrollment. Study Design: A randomized controlled trial. Arms, Groups, and Intervention: Participants were blinded to an assigned diet which was either the (1) calorie-restricted low-carbohydrate diet (20%-25% CHO, 40%-50%% protein, 30%-35% fat, n=60) or the (2) calorie-restricted balance diet (55%-65% CHO, 15%-20% protein, 20%-25% fat, n=60). Intervention Duration: 8 weeks. Visits: The subjects were followed up by the same clinicians at the Outpatient Clinic and by dieticians at 0, 2, 4, and 8 weeks.
