PROJECT SUMMARY Type 2 diabetes mellitus (DM2) causes significant morbidity and mortality. Diet can be a powerful tool for treatment of DM2, but the potential impact of diet has not been fully realized, which may be because usual recommendations include the challenging goals of caloric restriction and weight loss. An isocaloric, moderate carbohydrate, high protein diet (the Low Biologically Available Glucose, or LoBAG, diet) has been designed specifically for people with DM2, and is unique because it does not require caloric restriction or weight loss to produce beneficial effects. Data from preliminary efficacy studies are exciting, but are limited in generalizability. The purpose of the proposed project is to expand generalizability by testing the effectiveness of the LoBAG diet in people with DM2 who are free-living (given diet instruction and asked to prepare their own food). This project is proposed as a key component of a five-year career development plan for Dr. Anne Bantle, an endocrinologist and early career investigator at the University of Minnesota. Dr. Bantle’s long-term goal is to become an independent clinician investigator with expertise in treatment of DM2, with particular focus on diet and the gut microbiome. Her career development plan will allow her to 1) develop expertise in clinical research as a principal investigator, 2) develop expertise in DM2, diet, and gut microbiome, 3) develop skills necessary to lead an interdisciplinary research team, and 4) generate preliminary data to support future funding applications. Specific career development activities will include completion of a Master’s Degree in Clinical Research, hands- on training through implementation of the proposed research study and as a co-investigator in multicenter clinical trials, instruction in gut microbiome analysis, attendance and participation in research meetings, and ultimately, successful application for independent funding. The proposed research project will test the hypothesis that the LoBAG diet is effective in free-living participants with DM2, and specifically that consumption of the LoBAG diet will result in greater reduction of hemoglobin A1c than consumption of a control diet, without requiring caloric restriction or weight loss. Thirty-eight participants will be enrolled in a randomized controlled clinical trial of the LoBAG diet versus a control diet over a 12-week intervention period. Specific aims are to 1) determine the effect of the LoBAG diet compared to control on glycemic control, 2) determine the effect of the LoBAG diet compared to control on compliance and quality of life, and 3) determine if features of the gut microbiome are predictive of glycemic response to diet. It is anticipated that this project will generate preliminary data for a future larger, definitive effectiveness trial. The skills and expertise gained from the proposed career development plan and research project will allow Dr. Bantle to successfully emerge as an independent investigator, and will lay the groundwork for her to become a leading scientist in the field of DM2, diet, and gut microbiome.

项目总结 2型糖尿病(DM2)会导致严重的发病率和死亡率。节食可以是一种强大的工具 治疗DM2，但饮食的潜在影响还没有完全认识到，这可能是因为平时 建议包括具有挑战性的卡路里限制和减肥目标。等卡路里的，中等热量的 碳水化合物、高蛋白饮食(低生物可利用葡萄糖或LoBAG饮食)已经设计出来 特别针对患有DM2的人，它是独特的，因为它不需要限制卡路里或减肥来 产生有益的效果。来自初步疗效研究的数据令人兴奋，但推广能力有限。 拟议项目的目的是通过测试LoBAG饮食的有效性来扩大普适性 在自由生活(给予饮食指导并要求自己准备食物)的DM2患者中。 该项目被提议作为Anne Bantle博士五年职业发展计划的一个关键组成部分 明尼苏达大学的内分泌学家和早期职业研究员。班特尔博士的长期目标是 成为一名独立的临床研究员，具有治疗DM2的专业知识，尤其关注饮食 还有肠道微生物群。她的职业发展计划将使她能够发展临床研究方面的专业知识 作为首席研究员，2)开发DM2、饮食和肠道微生物组方面的专业知识，3)开发必要的技能，以 领导一个跨学科的研究团队，以及4)生成初步数据以支持未来的资金申请。 具体的职业发展活动将包括完成临床研究硕士学位，手- 通过实施建议的研究研究并作为多中心临床联合研究人员进行培训 试验，肠道微生物组分析的指导，出席和参加研究会议，最终， 成功申请独立资助。 拟议的研究项目将检验LoBAG饮食对自由生活参与者有效的假设 对于DM2，特别是LoBAG饮食的消费将导致血红蛋白A1c的更大降低 而不需要限制卡路里或减肥。38人参加 将参加为期12周的LoBAG饮食与对照饮食的随机对照临床试验 干预期。具体目标是1)确定LoBAG饮食与对照相比对 血糖控制，2)确定LoBAG饮食与对照相比对依从性和质量的影响 生命，以及3)确定肠道微生物群的特征是否可以预测饮食的血糖反应。这是意料之中的 该项目将为未来更大规模的最终有效性试验产生初步数据。 从拟议的职业发展计划和研究项目中获得的技能和专业知识将使Dr。 班特尔成功地成为一名独立调查员，并将为她成为一名 DM2、饮食和肠道微生物组领域的领先科学家。
